Rotating the Jog Dial takes the user through a menu of the most important applications. Clicking the Jog Dial or pressing OK will select the application, for example the Calendar.
The standby screen may be personalised with photographs. The user may also personalise the application menu.
Pressing the Menu button brings up a set of options relevant for the current application. The Jog Dial may be used to make a selection, or the corresponding numeric key on the keypad may be pressed as a shortcut.
During a phone call, the user has access to most applications, making it possible to look up appointments, contacts, etc whilst chatting on the phone.
The P800 enables Latin characters to be entered via the keys on the flip. Characters are selected by pressing the key until the required one is shown. The P802 supports Chinese character input using Stroke, Pinyin and Bopomofo.

The flip may also be removed. A ‘flip replacement’ cover is clipped in place instead of the flip:

Replacement
When the flip is open or removed, a ‘virtual flip’ can be displayed on the screen. It works in exactly the same way as the hardware flip, except that the buttons are represented on the touch screen. The main uses of the virtual flip are:
• FC input methods (especially for the Chinese versions)
•
SIM-AT
•
Keylock
The virtual flip is enabled or disabled in the Control Panel. When enabled, the symbol is shown in the status bar. Tapping the symbol displays the virtual flip. The virtual flip is ‘opened’ (removed from the screen) by tapping the arrow symbol
.

The user may select five important applications and display them on the ‘application picker’ strip across the top of the screen. The sixth icon at the right always switches to the Application Launcher.
All applications are listed in the Application Launcher. The user may select list view with small icons and text, or a ‘finger-size’ icon display of 8 applications per page. One tap on the list-row or icon will launch (switch to) the desired application.
The Folder feature enables the user to group applications into logical folders such as ‘games’ and ‘work’. This feature is carried through into many applications, enabling contacts, appointments, notes etc. to be organised effectively.
The Jog Dial can also be used to navigate up and down; clicking on an application will navigate to it.
There is no concept of starting or closing applications; simply navigating to them. When an application is used for the first time it will start in its basic state, which is typically a list view. If the user navigates from application A to application B (using, say, the Application Picker,) application A will close any open dialogs and views and return to its initial state ready for the next time it is used. Data is saved. There are some exceptions, for example the browser stays at the current page.
Here is an example of a list view. This is the normal state of the Contacts application.
Tapping on the folder drop-down, the list can be filtered to show just one folder, for example business or personal.
A tap on the desired item will open the detail view.
Lists typically scroll a page at a time. The scroller may be found in the lower corner of the screen.
As in the application launcher, the Jog Dial can be used to select an item. This provides a useful ‘one-handed’ way of operating the P800 in FO mode.
16
P800/P802
Here is the detail view in the contacts application. The most important information is displayed directly. Further information is organised by using tabs; in this case notes and a picture.
A conventional menu structure is provided for tasks and actions.
Changing the folder here will re­classify this entry. Entries default to ‘all’ or ‘unfiled’.
Tapping on a telephone number will navigate to the phone application to make a call. Similarly, tapping an E-Mail address will navigate to the E-Mail application and create a new E-Mail to the contact.
Management functions such as delete, copy to Memory Stick or Send As are performed in detail view.
As before, the Jog Dial can be used to perform these operations one-handed. Scrolling the Jog Dial will move the highlight and pressing Select will initiate the chosen action (telephone call, new e-mail etc.)
Status Bar
The status bar shows the normal items such as signal strength and battery meter. In FO mode, the icons may be tapped to see further information and access relevant settings. Tapping the keyboard icon whilst entering text enables the user to switch between handwriting recognition and on-screen keyboard. More icons are used to indicate temporary conditions such as , Bluetooth activity, ongoing call and internet connection status.

P800 Memory Organisation
Data Storage Locations
The P800 is divided into two parts:
•
A GSM phone part, having flash memory. This is very similar to a conventional mobile phone such as the T68i
•
An ‘Organizer’ part running Symbian OS and having a large amount of flash and RAM memory plus a Memory Stick slot and ability to exchange files with a PC.
Note: The ‘Phone’ application which provides the phone MMI exists on the Symbian OS part of the P800; the GSM stack resides in the GSM phone part.
The diagram below shows the memory organisation of a P800:
The RAM (Random Access) memory is controlled by the Symbian OS operating system and is not used to store any user or program data. All use is dynamic and managed by the OS. The RAM is totally re-initialised when the P800 is started.
Two banks of 16Mbyte flash memory are built into the P800, making a total of 32Mbyte. Flash memory retains data even with no power applied. Unlike some PDA devices, the P800 does not require a small ‘memory backup’ battery. Data stored on the P800 is therefore not subject to loss due to such a battery running down.
The first bank is used like a ROM. It stores the Symbian OS (UIQ) operating system, the built-in applications and some essential multimedia information like a default ring tone. It also stores the language files for UK English. This is the default language of the P800.
18
P800/P802
Note: The extensive MMI of the P800 means that it is impractical to hold many languages inside the phone, as is done for some other models.
The second 16Mbyte bank of flash memory is divided into two parts. The first 4 Mbyte is reserved. It is essentially an extension of the ROM area.
The rest of the second bank provides a ‘C:’ drive of 12 Mbyte capacity. This behaves just like a normal disk drive. Some folders can even be viewed and managed from a connected PC. In the Chinese version the reserved area is 7Mbyte and the C: drive is 9Mbyte
When a P800 is updated at a Sony Ericsson Service Point, or over the internet using the Sony Ericsson Update Service, all three banks of flash memory will be rewritten. User data that has previously been backed up to a PC can be restored to the C: drive afterwards.
User Storage
The user storage space (C: drive) is shared across applications without any imposed restrictions, apart from the whole space becoming full. For example, one user might use the entire user storage space for photographs, in which case over 200 can be stored. Another user might load a third party street map application and a number of street maps. In this case, the application will take up some of the storage space and so will each map. When space becomes limited, the user can choose to remove some maps.
Unlike a PC, the user does not need to be aware of the underlying filing system. Applications will always make sensible choices and store information automatically, simplifying management of data. Third party applications may implement more complex file management solutions where required.
Additional storage space is available by using Memory Stick Duo. A 16Mbyte Memory Stick Duo is included with the P800. Any number of Memory Stick Duos may be used with the P800. See ‘Memory Stick Duo’ later in this paper for more information. Memory Sticks up to 128Mbyte capacity are supported.
Depending on the application, data can be beamed, mailed, uploaded to the web or transferred over the link to a PC in order to archive and create free user space on the P800 – see ‘Synchronisation and Data Transfer’ later in this paper.
User Storage configuration in a new P800
Applications and information are placed in the internal storage of the P800 in the factory. This provides sample demonstration, educational, multimedia and fun content so that the P800 can be used directly out of the box. Much of this can be deleted by the user in order to make the space available for personal use.
This section describes the case for a generic (non-customised) P800.
User Data
This space is initially empty. Normal uses are:
• User-data associated with built-in applications (e.g. Messaging, Contacts)
• Applications installed by the user
•
Multimedia content added by the user
Settings
Settings such as dial-up networking and e-mail account information. Initially Empty.
19
P800/P802
Sony Ericsson Multimedia Content
Sound, pictures, video and other files chosen to show off the capabilities of the P800. This is described in more detail in ‘Customisation and Personalisation’ later in this document.
Application Files
Three applications are stored on the C drive: Chess, Solitaire and P800 Demonstration. The user may uninstall them in order to free space on the C: drive.
Language Files
The generic P800 is prepared for different markets. A maximum of 6 languages can be placed in this area. This is set by convention; the file system does not impose any limit other than overall

P800/P802
capacity. A ‘Load Module’ is constructed containing the languages for a given market. Therefore a number of load modules is specified for the P800 to cover all required markets.
Language is selected at First Startup and Master Reset.
Action when P800 is Initialised
When the P800 is first started, the user is prompted to select a language as part of the initialisation procedure. The P800 is then restarted.
If the user selected UK English, all of the alternative language files will be deleted, making 2.6MB extra space free on the C: drive in the above example.
If the user selected any language other than UK English, then the selected language files are retained on the C: drive and the other language files are deleted. In this example, we assume that the user has selected Swedish and therefore the Danish, Finnish and Norwegian files are deleted during the restart procedure. In this case, approximately 1950KB is made free on the C: drive.
The diagram below illustrates this for a generic P800, where the free user data area on the C: drive grows to 8.15MB.
P800 C: drive contents after first user initialisation
21
P800/P802
Action at Master Reset
Master Reset will delete everything on the C: drive except for Languages and (if selected by the user) user-installed applications.
If a newly-initialised P800 goes through a Master Reset, the C: drive will look like this afterwards. If the user had included user-installed applications, then the P800 Demo, Chess and Solitaire would be deleted also.
P800 C: Drive after Initialisation and Master Reset
Data can be restored as follows:
If the user has previously backed up the P800 using the PC Suite, then the C: drive can be restored to the exact condition it was in when the backup was made.
Otherwise, data can be re-loaded from the following places:
•
Sony Ericsson Multimedia Content from the P800 Multimedia CD-ROM
• Applications Chess, Solitaire and P800 Demo from the P800 Multimedia CD-ROM
Since Multimedia content is easily transferable using Memory Stick, infrared or Bluetooth wireless technology beaming, it is simple to restore favourite content from someone else’s P800.
22
P800/P802
Folder View of Internal Storage
This section explains in more detail how the data is organised on the C: drive. Note: The actual file and folder structure on the P800 is not exactly as shown in this document.
When viewed from a PC using PC Suite for P800, the ‘C:’ drive is named ‘Phone Memory’, but only a subset of the folders is accessible from the PC.
Language files are represented by the Language Files folder. The user has no access to this data.
Multimedia is stored in a structure beneath the Media Files folder. There is a folder for each media type: audio, video and image. Documents (such as Microsoft Word files) are stored under the Document folder. An Other folder provides a place for files that do not fit into the other categories.
Beneath each media type and documents, the material on the P800 is broken into Folders. For each named folder in the related P800 application, a folder is created beneath the applicable media type. For example if the user creates a ‘MyMP3’ folder in the Audio Player application, a ‘MyMP3’ subfolder is created beneath the audio folder. Unfiled folders are created in the initial folder structure and all material, including Sony Ericsson Multimedia Content, is placed in the unfiled folder by default.
Generic P800 C: drive folder structure (simplified)
In the above diagram, the folder structure is shown and the Sony Ericsson Multimedia Content (audio) files can be seen.
23
P800/P802
Phone and PIM Applications
Phone
The P800 is a full-featured mobile phone having full integration with the other functions of the device, including third party applications.
The phone includes useful and fun features such as:
•
Personalised ringtones – conventional or polyphonic ringtones can be set in Contacts, giving audible indication of who is calling. Supported formats are AMR, Au, iMelody, MIDI, RMF (Beatnik) and WAV.
• Picture Phone Book – if there is a picture of the person in Contacts, it will be displayed when making outgoing calls and when receiving the CLI with an incoming call.
• Quick access back to the entry in Contacts, making it easy to try an alternative number or send an E-Mail if the contact is unavailable or busy.
•
Voice dialling – make a call by speaking the contact’s name. The contact’s name may be recorded when entering/editing the entry in Contacts. The call is made by pressing the OK button on the flip or the button on the headset. If a ‘magic word’ is recorded, contacts may be dialled by saying the magic word followed by the contact name. It is then not necessary to press any buttons.
• Voice answer – an incoming call may be answered or sent busy signal, using the words recorded for ‘answer’ and ‘busy’. There is 40 seconds of storage space allocated for voice dialling and voice answer. This is enough for approximately 50 words (contact names plus ‘magic word’, ‘answer’ and ‘busy’)
• Access to most other applications whilst talking on the phone.
•
Office handsfree (speakerphone) which is enabled when the flip is open, making it easy to access applications such as Calendar and Jotter whilst talking.
• Flight mode enables the P800 to be used as a PDA in situations where radio transmitters may not be used. The GSM and Bluetooth transmitters (and receivers) are switched off.
In FC mode, the phone is driven by the keypad, like a conventional mobile phone.
24
P800/P802
If the flip is opened, the phone application re-scales itself to the full screen size. Other P800 flip closed applications are able to do this too.
A traditional keypad view is available.
The shortcut view provides one-touch dialling to 9 contacts.
A call log view provides summary details of calls made, received and missed. Full details can be viewed from here.
The shortcut view automatically takes pictures from Contacts and places them under the shortcut button. The Jog Dial also works in this view; scroll to highlight the desired contact and press Select to call.
25
P800/P802
Contacts
The P800’s Contacts application holds the details of all the user’s contacts. It is available in FC and FO modes and is fully integrated with the phone and other PIM applications. Each contact can contain multiple phone numbers and E-Mail addresses, name and address details, personal notes and a photograph of the contact or other image. This information will typically be synchronised in to the P800 to begin with; contact data can also be added and edited on the P800 itself. Local and remote synchronisation is possible to the SyncML standard.
Contact data can be beamed in or out using Infrared and Bluetooth. It can also be sent and received using messaging. See the Object Exchange section for full details.
Contacts are displayed in a list, which may be filtered by folder such as business or personal. Use the Jog Dial or stylus to select the required person.
Key communication details are displayed first. One tap will initiate a phone call, new message or URL in the browser. The Jog Dial can also be used.
Photograph of Rosie stored in Contacts.
A voice dial tag can be recorded, enabling Rosie to be called by saying her name.
A personal ringtone sound can also be set. It will be played whenever Rosie calls and her CLI is passed to the P800.
Picture formats supported: BMP, GIF, JPG, MBM, PNG, WBMP.
Audio formats for ringtones: AMR, AU, iMelody, MIDI, RMF, WAV.
26
P800/P802
Calendar
The Calendar application keeps track of appointments and events and enables reminder alarms to be set. The alarm sound can be personalised, using any of the supported sound formats. Appointments can be shared using Infrared and Bluetooth beaming and also messaging. Local & remote synchronisation are both supported using SyncML. The P802 supports the lunar calendar.
Week and month views provide a high level view of

27
P800/P802
Jotter
The Jotter application provides a quick means of making notes in either text or sketch format.
Notes are displayed in a list format for fast reference. The pencil indicates a sketch.
Text notes can be input using handwriting recognition or the virtual keyboard.
Time, Voice Memo and Calculator
Time is a sophisticated alarm clock which can show the time both locally and in another time zone. Alarms can be set. The alarm signal can be personalised using sound clips.
Voice Memo is a simple screen-driven dictation machine with the added advantage that recordings can be beamed and exchanged via messaging. It can also be used to record a personal ringtone.
Diagrams and sketches can be made in colour, using the stylus like a pen.
Calculator performs like a standard desk calculator, and is always available from the application launcher.

Description
Advanced Audio Coding. This is one of the audio compression formats defined within the MPEG-2 standard. Compared to MP3 it has more advanced features and is more efficient. AAC is commonly used as the audio component of an MPEG-4 video file or stream. The P800 Video Player can play AAC format audio which is encoded into an MPEG-4 file or stream. Such audio-only content is not common.
Adaptive Multi Rate. AMR is a speech compression format that is highly optimised for the mobile environment, requiring as little as 4.75kbps bandwidth. AMR is used to convey voice recordings in MMS, when the P800 records at a rate of 12.2kbps. Sample rate is 8kHz and processing is done on 20ms frames.
Similar to WAV, this is an audio format commonly used in the Macintosh, unix and java worlds. It is not commonly used for content on mobile devices.
A format commonly used for monophonic ringtones.
MIDI means Musical Instrument Digital Interface. MIDI specifies a format which describes music in a binary format which may then be stored as a file. Unlike the other formats, MIDI is not a recording of music but a description which enables a local synthesizer to play the music from the instructions included in the MIDI file. MIDI is ideal for polyphonic ringtones.
The P800 includes the Beatnik mini-BAE providing support for General MIDI Level 1.
MPEG1 Layer 3 audio compression. MP3 is a very popular format for downloading songs from the internet. It is also increasingly available in personal and in-car audio equipment. MP3 files can be created with different size/quality compromises.
Rich Music Format compact size of MIDI files with the high quality of sampled sound.
This is an typically used for short ‘alert’ sounds. The size of files is determined by sample rate, bits-per-sample and mono/stereo.

Loudspeaker Characteristics
General
The P800’s built-in loudspeaker is most sensitive to middle and high frequencies; tones below 400Hz generate distortion instead of bass. Therefore, sampling frequency for WAV should not be reduced below 16kHz, otherwise the characteristic low frequency sampling ‘ringing’ will be very distinct compared to that of a more linear system.
Recommended WAV file format for the loudspeaker is 22.050kHz sampling rate, 8-bit samples and 1-channel (mono).
Recommended MP3 setting for playback over the loudspeaker is 64kbps
P800 Loudspeaker
mono.
Ringtones
The stimuli should be kept around 4 kHz in order to generate high SPL (~90dBSPL@40cm) ring tones (see frequency response in figure below).
The speaker will accentuate with-in this band and alter the timbre of the ringer tones for frequencies around 2kHz. E.g. a square wave at 500Hz will not sound the same as a square wave at 2 kHz as is the case for a more linear system.
Recommendation: Keep the bandwidth of stimuli as narrow as possible. For discrete signals (~80dBSPL@40cm) the band broadens to 2-5 kHz. These types of stimuli can be generated at a larger bandwidth as an analogue to the above reasoning.
Stereo Headphone Characteristics
The P800 is supplied with a pair of high quality stereo headphones.
Recommended WAV file format for playback over the headphones is 44.1kHz sampling rate,16-bit samples and 2-channel (stereo). Files to this standard are very large – use WAV only for short bursts of sound.
Recommended MP3 settings are 128kbps stereo.

Description
Microsoft Windows Bitmap. A graphics format defined by Microsoft supporting 1, 4, 8 or 24 bit colour depth. No compression, so files can be very large. Used for icons and very small images.
Graphics Interchange Format. Highly compressed by limiting the colour palette to 16 or 256 colours. GIF is therefore good for icons and diagrams. When a Jotter sketch is send as an e-mail attachment, the GIF format is used.
A GIF file containing a number of images in a timed and repeating sequence. Some P800 applications display only the first image in the sequence.
An image compression format managed by the Joint Photographic Experts Group. The format supports various degrees of compression, enabling different quality/file-size balances to be provided in one standard. JPG files support millions of colours and are therefore good for ‘real life’ photographs.
Multi Bitmap. This is a Symbian OS format for colour and greyscale bitmap images.
Portable Network Graphics. PNG compresses images with millions of colours no loss of detail, but has comparatively large file size. It is not commonly used.
Wireless BitMap. Part of the WAP specifications, an image format optimised for small mobile devices. The P800 supports Black and White, 2-bit greyscale and 6-bit colour modes, according to ETSI 3GPP TS 23.040
Colour Screen
Images having more than 4096 colours will be adjusted to display optimally within the capabilities of the P800 screen.
Images larger than the display area will generally be scaled to fit the application window.
The Image Viewer uses 192 x 144 pixels in full screen mode.

Data Flow Summary
The diagram below shows a generalised view of the ways in which data can be imported, stored and exported. Data is stored in a generic multimedia structure for images, audio, documents, video and other. Therefore an image received as an e-mail attachment can be saved and used by any application capable of reading it.
Beaming
When an infrared or Bluetooth beamed object is received, the user is immediately notified via a dialog box on screen. The object can be viewed, saved or deleted. If no action is taken, the object is saved in the Beamed Inbox in Messages.
The Send As command in many applications allows an item of data to be beamed from the P800. For more information see ‘Synchronisation and Data Transfer’ later in this document.
Viewer
The ‘Viewer’ boxes in the diagram are instances of P800 applications that show selected details of the object and provide an option to save the object and/or go back.
Messages
Objects embedded in or attached to messages can be viewed and saved via the Viewer mechanism described above. Wallpaper and ringtones can be set directly from MMS messages.
The Send As command in many applications allows objects to be sent from the P800. It is also possible to add multimedia attachments whilst composing MMS and e-mail messages.
34
P800/P802
Application Behaviour
This section highlights certain application capabilities that are useful to understand.
Browser
The Browser is able to read HTML based content from local storage. More importantly, a long tap on an object such as a picture will display a menu, from which it is possible to save the object to storage. This enables images to be collected and saved in internal or Memory Stick storage.
Folder Mechanism
Almost all applications use folders to allow the user to sort information into useful groups. This mechanism can also be used to move an object between the Internal Storage and the Memory Stick. The Media Format and Application Summary table above shows which built-in applications have this ability. A separate application menu function, where provided, enables an object to be copied between Internal Storage and Memory Stick.
Control Panel
Wallpaper. Screen Saver and default ringtone are set here. Refer to ‘Personalisation and Customisation’ later in this document for more information.
Contacts
In Contacts, the user can select a picture from the P800 storage and save a copy against a contact. A compatible audio file can be linked to a contact and played as a ringtone when that contact is identified as the calling party.
PC Suite for P800
The PC Suite for P800 enables multimedia content to be freely copied and moved between the P800 storage and a connected PC. The Internal Storage and Memory Stick appear as separate drives when viewed from the PC. See ‘Synchronisation and Data Transfer’ later in this document for more information.
35
P800/P802
P800 Audio Player
The P800 Audio Player is a multi-format digital audio player which enables the user to play a selection of favourite songs.
Songs may be stored in the internal P800 user storage and on Memory Stick. The folder system enables the user to organise songs into groups and create simple playlists of MP3 songs. It also allows songs to be moved between internal and Memory Stick storage.
Songs may be collected in numerous ways, including internet download, file transfer from the PC using SyncStation and, of course, Memory Stick.
The Audio Player is intelligently aware of other applications on the P800:
• Playback is paused when a telephone call is made or received
•
Playback is paused if the user starts another application which requires the audio channels to be dedicated to it.
• Playback of MP3 files continues if the user switches to another FO application or closes the flip, providing music whilst using other applications such as PIM or Messages.
The Audio Player is started from the Application Launcher and is accessed in Flip Open mode.
Folder ‘All’ is selected. It contains the songs listed in the lower half of the screen.

Imaging
Built-In CommuniCam
The P800 has a built-in camera capable of taking still pictures up to 640 x 480 pixel (VGA) resolution (307200 pixels) and 24 bit colour depth. 320 x 240 (QVGA) and 160 x 120 (QQVGA) pixel sizes are also selectable. The camera may be used in Flip Closed mode for fast point-and­shoot pictures using the screen as the viewfinder. The lens is recessed into the back of the P800. With the flip open, the viewfinder is supplemented with graphical controls and access to camera settings. The viewfinder is always 160 x 120 pixels, irrespective of the resolution at which the picture is taken. A dedicated hardware button provides fast access to the camera application.
Images are stored in the P800’s filing system and are therefore available for other applications to use. The number of images that can be stored depends on the available file space, which is shared with other applications. In FO mode, the viewfinder will give an estimation of the number of images remaining, assuming that all of the free storage is available for the camera application and using the current settings for size and quality. Approximate JPEG file sizes are 50kbytes for VGA, 18kbytes for QVGA and 3kbytes for QQVGA.
Images are placed into a user-definable folder on either internal or Memory Stick storage. They may be viewed and organised in the Pictures application, and are available for use by other P800 and third party applications.
In Flip Closed mode, the camera is optimised for ‘point-and-shoot’ speed:
•
Dedicated CommuniCam button
•
Ready/Busy indicator
• Delay Timer icon audible 15 second ‘countdown’ to the shot.
The first press on the CommuniCam button will switch on the viewfinder. Each further press on the button will then act as a shutter and take a picture.
With the flip open, additional on-screen controls are:
• Shutter
• View all pictures (shortcut to Pictures)
Settings are accessed via the CommuniCam menu and include:
• Image size
• High/Medium/Low quality (low uses least
storage space)
•
Brightness and Contrast
• Backlight mode (when there is light behind the subject in the viewfinder)
• Flicker-free mode (for fluorescent lighting)
•
White Balance (automatic or one of 4 pre-set values)
Pictures remaining is calculated based on the current settings plus available space on the selected storage location (internal or Memory Stick).

P800/P802
Video Playback and Streaming
The P800 Video Player plays video content that is locally stored or streamed. It can also play audio-only material which is encapsulated within an MPEG file or stream.
MPEG-4 Standard
MPEG-4 was developed in 1998 by the Motion Pictures Expert Group, and has been incorporated into the 3GPP specifications for mobile multimedia. The earlier standards, MPEG-1 and MPEG-2 are widely in use for multimedia CD-ROMS and digital broadcast television for example. MPEG-4 has new functionality enabling to support both small mobile terminals and larger fixed devices within one standard. It has been adopted by 3GPP.
MPEG-4 has the following advantages:
• Flexible range of bit-rates supported, from 9.6kbps to 6Mbps (compared to 1.5 to 12Mbps for MPEG-2)
• High error resiliency
•
Variable frame rate, enabling optimisation based on the transmission path and the overall load on the server.
Video Compression
The video compression component of the standard is called MPEG-4 Visual and covers a range of bitrates and functionalities. Profiles are used to describe functionality packages. Simple Visual Profile provides efficient and error-resilient coding of video content, and is supported by the P800 Video Player.
MPEG-4 Visual is also broken down into levels, describing such things as frame size, bitrate and buffer capacity. Level 0 is targeted at mobile devices and provides for a frame size up to 176 x 144 pixels at maximum rate of 15 frames per second.
Audio Compression
AAC (Advanced Audio Coding) is one of the audio compression formats defined within the MPEG-2 standard. Compared to MP3 it has more advanced features and is more efficient.
The 3GPP standard uses AMR for audio coding, though this is actually outside of the MPEG-4 standard. This is because AMR is highly optimised for the mobile environment, requiring as little as 4.75kbps bandwidth.
File Format
The file format defined by MPEG-4 has extension MP4. It is applicable for both streaming and local storage/playback. MP4 uses a structured yet flexible method to describe and encapsulate multimedia material.
3GPP PSS (Packet Switched Streaming) Standard
What is streaming?
Streaming is a method of making audio, video and other multimedia available in near real-time, over the Internet or corporate intranets. Streaming media to computers has been used during the last few years, and now, with GPRS, EDGE and UMTS, the technique is can be used with mobile phones.
39
P800/P802
The name ‘streaming’ refers to the technique it is based on. Previously it was necessary to download an entire file to the hard disk or mobile phone and then play it, whereas through streaming the user can begin to watch or hear the content of a requested file after only a short delay. The data in the file is broken into small packets that are sent in a continuous flow, a stream, to the end-user’s computer or mobile phone. It is then possible to begin viewing the file from the beginning as the rest of the packets are transferred to the end-user’s machine or mobile phone while playing. The short delay at the start is to enable a small amount of data to be buffered. The data buffer enables playback to continue uninterrupted despite variations in the rate of received data.
Applications
The applications which can be built on top of the streaming services, can be classified into on­demand and live information delivery applications. Examples of the first category are music and video, news-on-demand applications as well as on-demand instructions material. Delivery of radio and television programmes are examples of live information delivery applications.
User scenarios
•
Streaming of music on demand
• Streaming of news (video, audio) on demand
•
Streaming of movie trailers on demand
•
Streaming and download of video on demand
• Live streaming of music/video (broadcast)
Standards, architecture and protocol
Sony Ericsson supports the architecture, protocols and codecs for the PSS (Packet Switched Streaming) within the 3GPP system, as well as supports all ongoing standardization activities within 3GPP. Sony Ericsson constantly works to follow standards and to ensure interoperability between business solutions, and also stands up to meet additional market requirements within this area. The relevant 3GPP specification is TS 26.233 “Transparent end-to-end packet switch streaming service (PSS).” The PSS includes media codecs for video, still images, bitmap graphics, text, audio, and speech.
P800 Video Player
The P800 Video Player is used in Flip Open mode.
Locally Stored Clips
Video clips may be downloaded from the internet or copied over from a connected PC. Video files are large compared to still images. The demonstration videos Sony Ericsson has shown on the P800 require approximately 1 Mbyte storage per minute. Video files may be stored on Memory Stick as well as internal storage.
Files must be .3GP or .MP4 having video coded in MPEG-4 Simple Visual Profile and audio in AAC or AMR format.
40
P800/P802
Video files can be stored on the P800, organised into user­defined folders if required. Tapping a filename will start playback.
The user may pause, rewind or fast-forward the playback.
The Video Player will also play audio-only material. (AAC or AMR encoded in an MPEG-4 wrapper)
Streaming Support in the P800
The Video Player can be launched from hyperlinks in the Browser or in messages. Content is streamed using RTSP (Real Time Streaming Protocol) session control according to 3GPP specification.
Audio support is AAC and GSM-AMR according to 3GPP
The following video codec support is provided according to 3GPP:
•
MPEG-4 Simple Visual Profile Level 0
•
H263 Profile 0 Level 10
• H263 Profile 3 Level 10

Memory Stick Usage Cases in the P800
Any number of Memory Stick Duo units can be used with a P800, providing virtually unlimited storage opportunities. Here are the main usage cases:
• Additional storage for pictures taken with the CommuniCam
•
Images from the CommuniCam can be transferred to other image-aware devices such as PCs and printers.
•
Transfer of data and media (sound, pictures, video clips, documents etc) between the P800 and a PC or Mac
• Save data and media from the P800 on to a Memory Stick, for example to make backup copies of important files.
• Transfer of data and media between P800s.
•
New applications may be installed from a Memory Stick.
•
Third party applications can make use of Memory Stick storage.
• Data can be transferred over SyncStation between a Memory Stick in the P800 and a connected PC.
•
Personalise the P800 using media on a Memory Stick, for example ring signals, alarm sounds and pictures of contacts.
•
Use media on a Memory Stick when composing MMS messages
Specifically, the following built-in applications are enabled to work with the Memory Stick: CommuniCam, Pictures, Video Player, Audio Player, E-Mail (attachments), Viewers (e.g. Word), MMS (media), Browser, Phone (ring signals, screensaver), Contacts (pictures of contacts; ringtones).
Compatibility with other Memory Stick devices
The P800 defines its own folder structure on a Memory Stick, within the vendor-specific area and this is the only area that is accessed. Other devices must therefore access the same folder structure in order to interact with P800 files and media. For a PC or Mac, this is easily done by browsing to the required folder on the Memory Stick. Memory Stick enabled devices with no browsing capability may be unable to share data with the P800. For example, it may not be possible for the P800 to read images taken on a Memory Stick enabled digital camera without first using a PC to copy them to the images folder within the P800 folder structure.
Magic Gate, the copyright protection mechanism available with Memory Stick, is not supported on the P800.
43
P800/P802
Memory Stick inserted in to a PC
Using the supplied Memory Stick Duo Adaptor, the P800’s Memory Stick Duo may be inserted into a memory-stick enabled PC.
In the example below, the Sony Vaio PC locates the Memory Stick on the S: drive. The memory stick is new and has been initialised by the P800. Note that some capacity is taken up by the filing system.
Folders MMSEMC and P-Series identify the data structure as that of the P800, according to defined Memory Stick conventions. Media data is stored in the standard P800 structure.

P800/P802
Messaging
The P800 Messages application has integrated support for SMS, EMS, MMS and E-Mail from a unified UI. Messages may be addressed using the contacts data and hyperlinks are supported in all message types to create E-Mails, call telephone numbers and navigate directly to web and WAP pages that are referenced in the text.
EMS (Enhanced Messaging Service)
Enhanced Messaging Service (EMS) adds new powerful functionality to the well-known SMS standard. With it, mobile phone users can add life to SMS text messaging in the form of pictures, animations, sound and formatted text. This gives the users new ways to express feelings, moods and personality in SMS messages. As well as messaging, users will enjoy collecting and swapping pictures and ring signals and other melodies.
EMS uses existing SMS infrastructure and industry standards, keeping investments to a minimum for operators and providing a familiar user interface and compatibility with existing phones and with other manufacturers. EMS is part of the 3GPP standards.
An EMS message can be sent to a mobile phone that does not support EMS, or only supports part of EMS. All the EMS elements i.e. text formatting, pictures, animations and sounds are located in the message header. The EMS contents will be ignored by a receiving phone that does not support the standard. Only the text message will be displayed to the receiver. This is true consumer-friendly standardization. EMS is compatible to SMS across most of the range of mobile
•
With the Short Message Service, a user can send text messages containing up to 160 characters to and from GSM mobile stations (up to 70 characters using Chinese text)
•
With concatenated SMS, the user can write a longer message and the P800 will automatically send it using more than one SMS.
• EMS (Enhanced Messaging Service) enables the user to include graphics, sounds and font attributes as part of a text message, which can then be sent over the normal GSM/SMS service. Such messages may also be received and the extra media objects saved.

phones from the oldest to the newest. Some companies in the mobile phone industry have developed their own messaging technologies, which only work with their own phone models. Network operators are in favour of EMS because it is universal – many of the major mobile phone manufacturers are constructively improving and developing the EMS standards even further for implementation in their products.
Examples of EMS contents and applications
A wide range of contents, applications and services may be developed. Below is a list of examples and areas where messaging can be enhanced with EMS:
• User-to-user message
•
Message notifications for voicemail, e-mail, unified messaging.
• Illustrated news & commercials
EMS Media Objects in the P800
Sounds and melodies
EMS sound is in the form of simple melodies according to the iMelody standard. Multiple sounds may be included in a message.
A library of sounds is included with the P800. Additional sounds may be copied from incoming EMS messages and pasted in to a new message. Sounds from received messages can also be stored in the ‘Melody’ folder within the EMS ‘Insert object’ menu.
EMS also has pre-defined sounds such as “Chime high” and “Notify.” Rather than sending the complete sound to the receiving phone, EMS sends a ‘token’ instructing the receiving phone to play that sound according to its own library. When the P800 receives a message that includes an EMS pre-defined sound, it will be played in polyphonic form.
The P800 does not include a melody composer for EMS, neither is it possible to set ringtones from melodies received in EMS messages as the P800 is better suited to polyphonic ringtones.
Pictures and Animations
EMS pictures and animations are in the form of small bitmaps. These are transmitted in binary black and white (meaning that there are no scales of grey in between). Multiple pictures can be added to a message.
8 x 8 pixels 16 x 16 pixels 32 x 32 pixels
A library of pictures is included with the P800. Images from received messages may also be saved to the ‘User Defined’ folder within the EMS ‘Insert object’ menu. These images can then be edited and re-used.
Pictures may be added to a message by copying and pasting them from received messages.
New images can be created using a simple grid and pen editor. Animations may not be created or edited.
EMS also has pre-defined images such as smileys. Rather than sending the bitmap, a simple token is sent to instruct the receiving phone to display the pre-defined image. The P800 will
46
P800/P802
display these images in colour, since a pre-defined image is always displayed from local P800 storage.
Example stored colour animation for EMS
The P800 does not support the use of EMS to set background images because other methods are more appropriate for the large size and colour capability of the P800’s screen.
Text
There are 3 text font sizes.
, italic, underline
Bold
and strike through styles are available, and text
may be aligned left, centre or right.
Concatenated messages
A part of the EMS standard is the support for concatenated messages, which means that the phone is able to automatically combine several messages both when creating and receiving EMS. This is useful to be able to build and display messages with rich content, since the amount of information in each SMS is limited by the SMS standards.
EMS Display in the P800
Receiving an EMS message in FC mode
In the P800, the extra facilities of EMS are integrated with the SMS UI, making it easy for the user to enrich an ordinary text message. A selection of icons and sound objects is included and more can be added via M-Services download.
Objects in received messages may be saved for re-use when composing outgoing messages, so as well as messaging users will enjoy collecting and swapping pictures, ring signals and other melodies.
Simply tap on the required object to copy or save it.
One message may contain several EMS objects, such as a pictures, animations and sounds..
Messages may be created using the keypad to enter text in FC mode, or using handwriting recognition or virtual keyboard in FO mode.

P800/P802
MMS (Multimedia Messaging Service)
One of the key features in the P800 is the Multimedia Messaging Service (MMS), expected to become the preferred messaging method of mobile terminal users, since the ability to send real pictures and sound greatly enhances the messaging experience. An MMS message from the P800 can contain text, graphics, animations, photographic images, audio clips, ring melodies and even a video clip.
Defined and specified by 3GPP as a standard for third generation implementation, MMS completes the potential of messaging. Sending digital postcards and multiple-slide style presentations is expected to be among the most popular user applications of MMS. Eagerly awaited by young users in particular, MMS is projected to fuel the growth of related market segments. Using the Wireless Application Protocol (WAP) as bearer technology and powered by the high speed transmission technologies GPRS, EDGE and UMTS (W-CDMA), Multimedia Messaging allows users to send and receive messages that combine text and media in slides, having a built-in timing sequence decided by the sender. The messages may include any combination of text, graphics, photographic images, speech and music clips. MMS will serve as the default mode of messaging on all terminals, making total content exchange second nature. From utility to sheer fun, it offers benefits at every level and to every kind of user.
Benefits
Essentially enabling the mobile terminal to serve as image processor and conveyor, Multimedia Messaging accommodates the exchange of important visual information as readily as it facilitates fun. Business and leisure usage of MMS will be dynamically merged, resulting in enhanced personal efficiency for users and increased network activity for operators. In short, MMS affords total usage for total communication. Because MMS uses WAP as its bearer technology and is being standardized by 3GPP, it has wide industry support and offers full interoperability, which is a major benefit to service providers and end users. Ease-of-use resulting from both the gradual steps of the messaging evolution and the continuity of user experience gained from interoperability is assured.
The MMS server, through which MMS messages are sent, supports flexible addressing (to both normal phone numbers (MSISDN) and e-mail accounts), which makes user interface more friendly and allows greater control for operators. The MMS server, moreover, is responsible for the instant delivery feature of MMS.
MMS objects
Although MMS is a direct descendant of SMS, the difference in content is dramatic. The size of an average SMS message is about 140 bytes, while the maximum size of an MMS message is limited only by the memory. Multimedia Messages will initially be in the range 30k-100kbytes. The P800 is optimised for messages up to 200kbytes. In the P800 the MMS inbox is only constrained by the amount of available user storage.
48
P800/P802
An MMS message can contain one or more of the following:
Text
Much larger amounts of text can be used in MMS messages when compared with SMS. Thousands of characters can be included in a message.
Audio
MMS provides the ability to send and receive recorded audio and polyphonic sounds in messages. Not only can users share a favourite song or ring signal with a friend, they can also use the mobile phone to record sound and send it along with a message. Because sound includes speech as well as music, this extra dimension of an MMS message makes for enhanced immediacy of expression and communication. Rather than sending a downloaded birthday jingle in EMS, for example, a user can send a clip of his or her own personal rendition of “Happy Birthday”.
Pictures
With the built-in CommuniCam, users can take a snapshot and immediately send it using the ‘Send As MMS’ facility. The ability to send pictures is one of the most exciting attributes of MMS, as it allows users to share meaningful moments with friends, family and colleagues.
Mobile picture transmission also offers inestimable utility in business applications, from sending on-site pictures of a construction project to capturing and storing an interesting design concept for later review. The ability to put text and pictures in a message allows users to create their own electronic postcards, an application that is expected to substantially cut into the traditional postcard-sending market.
The P800 supports the following image formats for MMS: GIF (including animated), JPEG, PNG, WBMP and BMP. Images may also be edited during message creation.
Video
The P800 can play MPEG4 video clips attached to MMS messages. They are opened as an attachment and played in the Video Player. Note that the MMS message is closed and control is transferred to the Video Player.
PIM Objects
With MMS in the P800, it is easy to send and receive business cards (vCard), Calendar and Tasks entries (vCal) and Jotter notes (text content is added to a slide). Received PIM objects are listed under the ‘Attachments’ tab.
SMIL presentations
SMIL stands for Synchronized Multimedia Integration Language and is pronounced “smile”. SMIL in the P800 allows the user to the create and transmit multiple-slide style presentations on the mobile device. SMIL is an advanced XML-based protocol, and Sony Ericsson MMS supports a subset of this protocol. Using a simple media editor, users can incorporate audio and animated GIFs along with still images, animations and text to assemble full multimedia presentations. The idea of SMIL is to allow the user to customize the page timing in slide presentations. The user can decide in which order the image and text will be displayed, as well as for how long the images and text lines are to be shown in the display. The user never sees the underlying SMIL code and does not need to understand it.
The P800 has an implementation of SMIL 2.0 Basic Profile. Messages created by the P800 use a subset of SMIL as defined in the Conformance Specification (see below).
49
P800/P802
SMIL Example
As an example, consider a two-slide message. In this case it was created using the Sony Ericsson MMS Home Studio described in the Personalisation and Customisation section of this document.
Slide 1
Picture (Slide_1.jpg) Text “this is my new car” Audio: Slide_1.midi
Slide 2
Picture (Slide_2.jpg) No text Audio: Slide_2.amr
The following files are used:
Slide.txt contains the text for slide 1. The SMIL conveyed in the mms.smil file looks like this example:
<smil> <head> <meta name="title" content="untitled" /> <meta name="author" content="MMS" /> <layout> <root-layout width="160" height="160" /> <region id="Image" width="160" height="120" left="0" top="0" /> <region id="Text" width="160" height="20" left="0" top="120" /> </layout> </head> <body> <par dur="35.723s"> <img src="Slide_1.jpg" region="Image" /> <audio src="Slide_1.mid" end="35.723s" /> <text src="Slide.txt" region="Text" /> </par> <par dur="6.026s"> <img src="Slide_2.jpg" region="Image" /> <audio src="Slide_2.amr" end="6.026s" /> </par> </body> </smil>
The components of the message will be encapsulated, like in the example below:
50
P800/P802
Media Object Timing
Timing of individual media objects must be within the overall slide time except for audio. This provides plenty of flexibility and greatly reduces the complexity of building a presentation.
The user may add text, an image and a sound clip to each slide. The timing of each within the slide can be adjusted. The default timings are as follows:
Object type Start Point
(Seconds from start of slide)
Default Duration (Seconds)
Text 0 5 seconds Image 0 5 seconds Animation 0 Duration of animation Audio 0 Duration of audio clip No Content 0 5 seconds
The user is not allowed to shorten the duration of a slide such that any media item would be truncated, meaning that the minimum duration of a slide is never less than the duration of the longest object within it.
The following example helps explain P800 timing behaviour:
The user creates a new message using the Blank template. An image and some text is added. Both of these are set to last 5 seconds, which is the default duration of a slide
A 4-second audio clip is now added. The duration of the slide is now set to the duration of the clip and the display time of the image and text objects is shortened too.
51
P800/P802
The user may shorten slide duration to less than the duration of the audio track. If there is audio on the next slide, the audio will be stopped and the track for the next slide will be played.
If there is no audio on the next slide, the audio track will continue playing until it finishes or a later slide is displayed which has its own audio track.
If Page time is un-checked, then the display time for the text can be set to shorter than the
Special case where audio can continue playing after the end of a slide.
page duration.
Templates
A template is a predefined message containing one or more slides. It may be modified by the user to quickly produce an attractive message. The Blank template is the default – in this case nothing is pre-selected and the user may create slides as required.
Users may store a favourite message as a template. Templates can also be deleted.
The P800 comes with 8 pre-defined templates, all of which have sound and an animated image (GIF format, 160 x 120 pixels). These and other useful content pre-loaded by Sony Ericsson are described in ‘Personalisation and Customisation’ later in this document.
Notification and download
Incoming multimedia messages are normally notified to the user as soon as they arrive, in the same way as text messages. Basic download options are:
• On – always download the message
•
Home only – messages are downloaded only when connected to the home network.
•
Off – download messages manually.
Additionally, filters may be set, based on:
•
Message size
• Message class (Advertisement, Information)
•
Anonymous sender (exclude messages from senders not listed in Contacts, or where sender information has been hidden)
Interoperability and Conformance
MMS is a very flexible and extendable specification. To help mobile operators launch MMS services that are consistent and reliable, Sony Ericsson, Nokia, Motorola, Siemens, CMG, Comverse and Logica have worked together to produce a Conformance Specification (‘MMS Conformance Document V2.0.0’). This provides additional guidelines that are intended to make sure that messages sent between different products are played back correctly.
The main areas covered by the specification are:
•
Picture formats (JPEG/JFIF, GIF, WBMP) and size (160 x 120 pixels)
• Sound format (AMR)
•
Slide layout (2 objects plus sound, layout is the same for all slides)
• SMIL subset (all timing elements are within a slide)
• Maximum message size of 30kbytes
52
P800/P802
The P800 has much greater capability than that stated above. The user may therefore choose between two conformance modes: Standard and None. The setting may be found in Control Panel, Messaging accounts, MMS, Advanced. Standard mode is useful when sending messages to smaller MMS-capable phones.
In Standard mode, the user may select any media items, but will be warned if the selection falls outside of the standard. For example:
•
Selection of a VGA (640 x 480) sized image will result in the warning “Recipient may not support this image size” being displayed. The user can choose to continue composing the MMS message, or select a different image. The image can be reduced to 160 x 120 pixels by taking it into the editor.
• If the message is greater than 30kbytes in size the warning “Recipient may not support this size of message” will be displayed
When ‘None’ is selected, no warnings are displayed.
When non-conformant messages are received, they will be displayed within the capability of the SMIL player. If the message is edited, objects may only be saved. If the message is saved as a template or forwarded then objects can be deleted or changed and new slides can be added.
Media Object Summary
The table below shows the media standards supported by MMS on the P800.

The MMS player will render all of the above formats. The display window for images is 200 x 120 pixels in FC mode and 200 x 200 pixels in FO mode. These are the optimal sizes for images where MMS messages are composed specifically for the P800. Incoming images larger than this will be re-scaled to fit within the window, preserving aspect ratio.
Standard None

P800/P802
Composing a multimedia message
Multimedia messages may be created in FC or, as shown below, in FO mode.
Composing an multimedia message is like building a small slide presentation. A typical slide will consist of a picture, some text and a sound. Text and sound can be added to complete a slide.
The user can set the duration of the slide. If a sound is added, the slide duration is set to the duration of the sound clip.
Slides can be chained together to make a sequence. Timing elements can be added to control the display of images and text within a slide. The user can preview the message before sending and make any timing adjustments via the UI. Slide order may also be changed.
Multimedia messages can be created using any suitable media in the user storage space – including media downloaded from
The MMS message is compiled using MIME standards and consists of the following parts:
• One part containing the description of the slides, using MMS SMIL.
•
One part containing the actual contents of the slides – text, images and sound.
the internet, synchronised from a PC or created on the P800 itself. Simply tap the placeholder in the slide template and select the required item.
An image editor is provided so that images may be modified before sending. The available functions are:
• Crop (Select a part of the picture, for example just the cat)
• Rotate
•
Pen (Draw on the picture in a choice of colour and thickness)
•
Scale (Resize image)
• Undo and Undo All operations
The pen function enables notes and drawings to be made on images. These become part of the image and cannot be erased separately from the image itself. The annotated image (with pen) is saved separately and sent with the message, leaving the original image unmarked.

Receiving a multimedia message
Incoming MMS messages typically arrive just like SMS messages – automatic delivery with notification to the user. Messages are located in the MMS Inbox.
FC playback of a multimedia message
FO playback
Receiving a multimedia message on other terminals
Interoperability is dependent upon the capability of the receiving terminal and the MMS server in the mobile network. Here are some examples.
The Sony Ericsson T68i is enhanced with MMS, enabling multimedia messages to be exchanged with excellent compatibility.
Hi Paul, here are my contact details as requested! Hope to speak to you soon.

A mobile without MMS may be sent the text by SMS together with a URL which enables the picture and message to be seen via the WAP browser.
55
P800/P802
MMS technical features
The MMS standard, just like SMS, offers store and forward transmission (instant delivery) of messages, rather than a mailbox-type model. MMS is a person-to-person communications solution, meaning that the user gets the message directly into the mobile. He or she doesn’t have to call the server to get the message downloaded to the mobile. GPRS enables a continuous connection and rapid transfer of data.
Architecture
The P800 communicates with the WAP Gateway using WAP transport protocols. That data is transported between the WAP Gateway and the MMS Relay using HTTP protocol.
The MMS Relay is at the centre of an MMS system. The MMS-C is primarily a message store. In some implementations the MMS-C is combined with the MMS Relay. The MMS Relay is linked to other MMS-Relays in order to forward MMS messages to external networks. The MMS relay can also send an MMS over e-mail using the SMTP protocol over the internet. The Relay can also format messages as SMS and send them via the SMS-C, enabling users of non-MMS terminals to receive MMS messages and view the text as SMS and the whole message via Web or WAP.
Example Usage Cases
User A will address a multimedia message to user B’s mobile number (MS-ISDN). The completed message will be sent via the WAP Gateway to the MMS-Relay. The MMS-Relay will store the message at the MMS-C and send a notification to User B’s T68i. The T68i will retrieve the message (depending on user settings) and the user will be able to read it from the MMS Inbox.
If User A sends an MMS to a user on a different network, the MMS-Relay will forward the message to the correct MMS-Relay in the target network (assuming interconnect agreements are in place) and the message will be stored in the MMS-C in the target network. It will be retrieved and read by the recipient’s mobile phone in the same way.
If User A sends an MMS to an e-mail address, the MMS-Relay will package the contents and use SMTP to send the message as an e-mail over the internet.
56
P800/P802
Message conversion
The MMS-C is able to perform limited message conversion - for example, from MMS to SMS – so that processing and air time is not wasted in sending messages to mobile terminals that do not have adequate capability to receive them. It also handles service aspects such as store and forward, guaranteed delivery, subscriber preferences, operator constraints, and billing information. The MMS-C also vouches for high quality messaging, e.g. by format conversion. This means that the MMS-C recognizes which formats are supported in the mobile phone, and adapts the MMS messages to these formats. The WAP User Agent Profile (UAProf) is used to communicate the handset’s capabilities to the MMS server. These features depend on the configuration of the MMS servers and will therefore be operator-dependent.
OTA configuration
Users can easily get MMS into their phone. MMS is configurable via OTA, meaning that the user does not have to configure the settings manually. The configuration is done by the operator.
E-Mail
P800 E-Mail Features
The P800 E-Mail client supports the following standards:
POP3 Post Office Protocol 3 POP is used to copy, move and delete messages
from an incoming mail server in the network
IMAP4 Internet Message Access
Protocol
MIME Multipurpose Internet Mail
Extension
These standards are supported by most Internet Service Providers and many corporate environments. Any number of E-Mail accounts may be set up – a typical configuration will be one business and one personal account. OTA configuration of E-Mail and ISP accounts is supported. E-Mail accounts and associated ISP accounts may be remotely configured over the air.
Built-in password generators from RSA Security and Secure Computing and make it possible for the P800 to connect corporate networks which use these popular access controls, so allowing corporate e-mail to be used.
When connected via GPRS, automatic polling can be used so that E-Mail is automatically collected and presented in the Inbox. Controls are provided to filter messages based on size, enabling cost and download time to be managed. Another option enables only e-mail headers to be presented in the inbox. Headers are quick to download. The user may read and select headers and request the message to be downloaded.
Attachments may be viewed using the built-in viewers for Microsoft and Adobe
®
Acrobat® (PDF). More viewers may be loaded from the supplied CD-ROM. See
Viewer section for more information.
A signature may be set up so that essential details are automatically copied to the end of each outgoing E-Mail.
The supplied PC Suite for P800 enables E-Mail to be synchronised with Microsoft
®
Lotus
Notes®. During synchronisation, new e-mail from the PC is transferred in to the
IMAP is also used to copy, move and delete messages from an incoming mail server. IMAP has more features than POP, but the P800 behaves in the same manner whichever is used. MIME is a protocol describing data, for example to define the attachments included in an e-mail.

corresponding ‘Synchronised e-mail account’ inbox on the P800. Messages and replies written using this account on the P800 are transferred and sent via the PC.
Web and WAP based E-Mail can, of course, be accessed using the P800’s browser.
Technical Explanation of E-Mail
Configuring and using the E-Mail client in Messages is very straightforward in most cases, especially where the e-mail service is provided by the mobile operator. Reading e-mail from third­party ISP services will normally work over GPRS with no problems. Sending e-mail may require some special configuration, however. This section provides a basic explanation of the end-to-end path involved in an e-mail transaction and some of the issues that may be encountered when using GPRS. Note that all examples refer to a POP server, but equally apply to an IMAP server.
A more detailed explanation of GSM and GPRS is given in the chapter ‘Technical Explanation of CSD, HSCSD and GPRS’ later in this document.
A common PC solution is to connect to the internet using a modem and a circuit-switch call over the public telephone network. In the diagram below, User B’s laptop PC uses this method to connect to the internet using Internet Service Provide ISP B.
User B has an e-mail address me@isp-b.net
and communicates with the POP server at ISP B to receive mail and uses the SMTP server at ISP B to send mail. Note that these servers are inside the ISP’s facility and that a firewall exists between the ISP and the internet itself.
When me@isp-b.net
sends an e-mail to me@isp-a.net, the e-mail client on User B’s laptop will connect to the SMTP server and ISP B, which will in turn connect over the internet to the POP server at ISP-A and transfer the message. The e-mail will be stored here until User A connects to retrieve waiting messages.
User A has a P800 and therefore several different ways of connecting to the internet:
1. Using CSD/HSCSD to an ISP service offered by the network operator or a third party
2. Using GPRS to connect to an e-mail service offered by the network operator
3. Using GPRS to connect to an e-mail service offered by a third party
58
P800/P802
In case (1) User A will connect using a circuit –switched call in much the same way as User B. A circuit-switch call will be established from the Interworking Centre (IWC) at the mobile operator to the modem bank at ISP-A. The P800 Messages application will perform a ‘Get&Send’ operation. Messages will access the POP server at ISP A and collect waiting messages.
If User A now replies to the message and selected ‘Send Now’ on the P800 whilst connected to internet, the Messages application will connect to the SMTP server at ISP A, which will in turn connect to the POP server at ISP B and the message will be transferred.
In Case (2) everything happens as in case (1) except that the connection to the ISP is made directly from the GSM/GPRS network using TCP/IP networking rather than modems. Because everything is managed by the mobile operator, the POP and SMTP servers can be made available.
In case (3) the P800 will be connected to the internet via the GSM/GPRS network and the route to the servers is over the internet. Most ISPs allow a connection from the internet to the POP server since access to the POP server is password-controlled. In other words, the firewall at ISP A will allow the connection from the P800 Messages application to the POP server to be made. The P800 will therefore be able to collect mail over GPRS.
Sending e-mail requires access to the SMTP server. The ISP will have configured the SMTP server to behave differently when the user is accessing it from the internet. This is done as a precaution against it being used to send spam (unwanted e-mail). E-mail send is therefore likely to fail when connected over GPRS and trying to use the third party ISP settings for SMTP.
Typical configurations include:
•
Block all external access to the SMTP Server
•
SMTP server works provided the sender address is in a domain belonging to the ISP.
• SMTP server works provided the recipient is in a domain belonging to the ISP.
•
SMTP server works only after a successful login has been made to an associated POP server.
•
SMTP server requires a username and password
There are a number of possible workarounds:
•
Switch to an e-mail service offered by the mobile operator
• Check if the SMTP server can be accessed in ‘Secure Mode’ using a password.
•
Find out if the mobile operator has an SMTP server configured to work where the sender e-mail address belongs to a different domain.
•
Try checking the mail on the POP server and then sending – some ISPs will allow access to the SMTP server from a user who has recently successfully logged in to the POP sever
•
Ask the ISP to allow external access from the IP number range used by the mobile operator’s GPRS service
• Connect to the ISP using CSD or HSCSD when e-mail needs to be sent
E-Mail Fetch and Delete Operation
The P800 is designed to work both as the only means of accessing e-mail and to work together with a PC which accesses the same e-mail account. It is useful to explain how each case works.
Basic Operation
The P800 Messages application fetches e-mail from the POP server using the COPY method. This means that each e-mail is copied from the sever and therefore two copies exist, one at the server and one in the P800 e-mail inbox.
When a message in the P800 inbox is deleted, the P800 will delete it from the server the next time it connects and does a ‘Get&Send’ operation.

P800 Server P800 Server P800 Server P800 Server
Starting state Get&Send 1 Deletions Get&Send 2
In the above example, there are 6 waiting e-mails on the POP server when the P800 does the first Get&Send for the mail account. After the Get&Send all 6 e-mails are copied to the P800 inbox (header only or body, depending on advanced settings). The user then deletes messages 2 and 5. After the second Get&Send, messages 2 and 5 have also gone from the POP server.
If the P800 discovers during a Get&Send that a message has been deleted from the server, for example by another e-mail client, then it will also be deleted from the P800 inbox.
Sent messages are stored in the P800. Sent e-mails will need to be deleted as required to free up storage space.
E-Mail account accessed only by the P800
The P800 e-mail inbox will stay synchronised with the POP mailbox at the ISP. The action of tidying up the P800 inbox will automatically tidy the POP server inbox upon the next Get&Send operation for the e-mail account in question.
E-Mail account accessed by the P800 and another device
A common configuration is to use the P800 to access e-mail whilst on the move, but to maintain a master copy of e-mail on a PC.
The E-Mail client on the PC must be set to copy from the server. For example, in Microsoft Outlook Express this is done by selecting Tools, Accounts, Properties, Advanced tab and tick ‘Leave a copy of messages on server’
All messages will now be received at both the P800 and the PC.
From time to time it will be necessary to delete messages on the P800 in order to create free storage. Before doing this, ensure that the PC has already collected the messages that will be deleted on the P800.
E-Mail account accessed by the P800 and another device – Alternative
If the P800 is only used for reading mail when away from the PC and it is not required to retain any mail on the P800 after it has been copied to the PC then this alternative may be preferred.
Leave the PC e-mail client on the default setting of MOVE messages from the server (i.e. do not leave a copy of the message on the server). In this case the behaviour will be as follows:
1. PC Sends and receives e-mail before leaving the office.
2. P800 inbox will be emptied if ‘Get&Send’ is performed immediately after the PC
3. New messages through the day will be received on the P800
4. Upon return to the office, a Send and Receive on the PC will collect the day’s messages, minus any that were deleted on the P800.
5. P800 inbox will emptied if ‘Get&Send’ is performed immediately after the PC

P800/P802
Area Information
Area Information, commonly known as SMS Cell Broadcast, is a method of sending text messages to mobile phones within a certain part of the network. For example, traffic news can be sent to users in a single cell or a group of cells. It is not widely deployed by network operators.
Information is organised into numbered channels. The user selects the required channels in the P800 Control Panel, Messaging Accounts, CBS tab. The requested text messages are received and placed in the ‘Area info’ mailbox.
Cell Information may be switched on and off in the Control Panel. When enabled and supported by the network, the ID of the current cell (or group of cells) will be displayed underneath the network operator name in the FC phone display. This is often the telephone area code or postal code of the current location.
61
P800/P802
Document Viewer
The P800 Viewer application enables the user to manage and view a wide range of document formats. A set of plug-ins is included for common document types and more can be loaded from the Multimedia for P800 CD-ROM. Viewer will list the documents that it finds on Internal and Memory Stick storage. Documents can be opened from the list.
Viewer is also automatically started when opening an e-mail attachment, in which case the user can also choose to save the document.
Exact options whilst viewing a document depend on the document type. For example, when viewing a Microsoft (text, tables, graphics) and Page (whole page on the screen) views are available. Text can be copied from the document and pasted into, for example, a Jotter note or an e-mail.
Viewer supports a subset of functionality in each case, for example Word headers and footers will not be displayed.
Documents can be exchanged using Memory Stick, infrared, Bluetooth wireless technology, MMS and e­mail.
Word document, draft (text only), Normal
When viewing a PDF document, it can be fitted to the width of the screen or to the window.
It is also possible to zoom in and out.

Browser, M-Services and MeT
The P800 features an integrated browser capable of browsing WAP, Web (HTML) and cHTML content from a common User Interface (UI).
M-Services
M-Services is a set of feature guidelines published by the GSM Association with the support of leading mobile network operators and handset manufacturers. These include easy start-up for the user, better user experiences, easy download of contents, and simple charging models. Technically, the guidelines cover existing standards including WAP, MMS, EMS, SIM-AT and SyncML. Requirements are also made in the areas of UI, MIME descriptors, media formats and codecs.
For developers and operators, this means that a standardised yet rich set of services can be deployed simply. Users will be able to enjoy a new world of consistently available and advanced mobile internet services such as:
• Pictures
•
Wallpapers
• Screensavers
•
Audio / Ring signals
• Games
The P800’s large colour touch-screen, dedicated browser access button and large amount of memory exceed the requirements of M-Services. The UI meets many of the recommendations. Since the P800 has a proper filing system for storage of media, download content is typically stored to file such that it is available to many applications including the P800’s personalisation settings. The P800 supports both WAP Provisioning and the established Ericsson/Nokia OTA provisioning standards – see Personalisation and Customisation section for more details.
MeT – Mobile electronic Transactions
With the introduction of WAP it has become possible to access mobile Internet services and undertake mobile e-commerce transactions. One of the key elements is the ability for any phone to operate with any service in this mobile e-commerce environment. This is why Sony Ericsson, Motorola, Nokia, Panasonic, NEC, Siemens and others have teamed together to create a common industry framework for mobile commerce - the Mobile electronic Transactions (MeT) initiative. Members come from handset manufacturers, financial institutes, mobile operators, security specialists and technology /solutions vendors. The MeT initiative co-operates with MasterCard International’s Global Mobile Commerce Forum.
MeT has the aim of establishing a framework for secure mobile transactions, ensuring a consistent user experience independent of device, service and network. It is a global initiative to ensure that interoperable mobile transaction solutions are developed around the world - enabling consumers to access goods and services seamlessly wherever they may be.
MeT builds upon existing industry standards such as WAP, WTLS, WIM and WPKI.
64
P800/P802
MeT covers the following core functions:
Initiation Providing the Personal Trusted Device (PTD) with key pairs for
authentication and signing.
Registration Providing the PTD with certificates associated with its keys.
Secure Connection Establish an encrypted link with the server in order to keep
information private.
User Authentication Prove the identity of an individual or an application.
Digital Signatures Authorise a contract by means of a user signing text (see example
below)
The P800 fulfils the compliance requirements for MeT version 1.0, (February 2001), according to the following MeT specifications:
•
Met Core Specification
• MeT PTD Security Requirements
•
MeT CUE Consistent User Experience
More information on MeT may be found at http://www.mobiletransaction.org/
MeT Example
Whilst shopping around for a new television set, the user finds a good price from a store and decides to order immediately. The store requests a ‘signed text’ confirmation from the customer:
As with many online transactions, the user enters all the details and must then press OK to confirm the transaction.
The user is requested to sign the transaction using a suitable certificate.
The certificate has a related signature PIN. The user enters the PIN to confirm the transaction.
65
P800/P802
P800 Browser
Content Types Supported
The P800 browser, called “Internet,” supports all of the following content types within a single browser, directly or via a gateway/proxy.
World Wide Web (WWW) - HTML
The WWW is the most popular method of publishing information on the internet and on company intranets. Content is organised using the Hypertext Markup Language (HTML).
The P800 browser can read HTML pages and therefore gives access to a vast amount of existing material. Of course, much of the content on the WWW is aimed at large screens and will therefore require scrolling on the P800. However some websites, and more frequently those of interest to the mobile user, have ‘low graphics’ or ‘mobile friendly’ options which are better suited to small screens.
HTML 3.2 is supported, minus some features that are applicable to large screen devices such as PCs. The main points to note are that the P800 browser does not support Frames or Javascript
Wireless Application Protocol (WAP) - WML
Wireless Application Protocol (WAP) 2.0 – xHTML
cHTML
WAP uses Wireless Markup Language (WML), which is like HTML but specially optimised for mobile devices. The P800 browser is compliant with WML 1.3 and therefore gives access to a world of existing WAP content. The large touch screen and multiple WAP accounts make it easy to access and surf WAP pages
Extensible Hypertext Markup Language, xHTML, is a combination of HTML 4.0 and XML, managed by the World Wide Web Consortium. xHTML Basic provides a common subset of features to enable the design of pages that will work on small handheld devices, yet rich enough for content authoring. In WAP 2.0, xHTML Basic is extended with additional markups to create xHTML Mobile Profile. This is the core markup language for WAP 2.0.
WAP 2.0 introduces many new facilities including colour graphics, animation, large file downloading and improved menu handling.
The P800 browser supports xHTML Mobile Profile.
Compact HTML is a version of HTML optimised for small handheld devices. It is widely used in Japan. The P800 browser will display cHTML content where it is available on the internet or from mobile operators over GSM/GPRS.
66
Browser UI
P800/P802
The browser is always close at hand, having a dedicated hardware button. It may also be reached from the application picker and the application launcher.
The browser is used in FO mode.
The touch screen makes navigation very quick and simple – just tap a bookmark or a link to navigate. The Jog Dial can also be used to scroll the page. To work with an object on a page, such as an image, tap and hold it. A menu will be displayed listing available options such as Save, Copy, Send As.
To open a new URL, click Internet and select Open Page. Local HTML content can be browsed, for example from the Memory Stick:
file:///d:/Media%20files/document/menu/menu.htm
Bookmarks and other information is presented in a simple list view. Just tap the text of a bookmark to view the page. Tap the icon to view the bookmark details. As in the R380, WAP Accounts may be stored in a bookmark, ensuring that the correct WAP/internet service provider is used to access the required page.
Pages may be saved to local storage. They are kept in the bookmarks list and may be opened offline.
WAP Push messages are received within the browser and presented in the list view.
The user may organise bookmarks into user-defined folders, for example creating a folder of sports bookmarks and a folder of transport bookmarks.
It is also possible to view a list of all signed documents (see MeT example above) and access incoming WAP Push messages.
67
P800/P802
Browser Security
World Wide Web
The P800 supports the TLS/SSL to provide a secure encrypted link between the browser and the website. This method is commonly used for secure transactions on the WWW. An icon in the display indicates when a secure connection is in use.
WAP Security
When using certain WAP services the user may want a secure connection between the phone and the WAP gateway, for example when using banking services. An icon in the display indicates when a secure connection is used. The P800 is based on the WAP 2.0 specifications where security functionality is specified with a technology called Wireless Transport Layer Security (WTLS) and WAP TLS Profile..
The WAP protocols that handle the connection, its transport and its security are structured in protocol layers. The security is handled by the WTLS layer operating above the transport protocol layer. There are 3 WTLS classes that define the levels of security for a WTLS connection:
• WTLS class 1 involves encryption with no authentication.
•
WTLS class 2 involves encryption with server authentication.
• WTLS class 3 involves encryption with both server and client authentication
Server authentication Requires a server certificate stored at the server side and a root
certificate stored at the client side.
Client authentication Requires a client certificate stored at the client side and a trusted
certificate stored at the server side.
A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys and algorithms needed for WTLS handshaking, encryption/decryption and signature generation. The WIM module can be placed on a SIM card and will then be referred to as a SWIM card.
Certificates
To use secure connections, the user needs to have certificates saved in the phone. User certificates can be downloaded. There are two types of certificates:
Certificate authority A certificate used to verify that a WAP site is genuine. If the phone
has a stored certificate of a certain type, it means the user can trust all WAP gateways which present a certificate that can be verified by the trusted certificate. Certificates can be preinstalled in the phone, pre-installed in the SWIM, or downloaded from the trusted supplier’s WAP page.
User certificate A personal certificate that verifies the user’s identity. A bank that the
user has a contract with may issue this kind of certificate. User certificates can be pre-installed in the SWIM card.
The P800 is loaded with WTLS/X509 certificates from Baltimore, CTE Cybertrust, Entrust, GlobalSign and VeriSign.
68
P800/P802
WIM Locks (PIN Codes)
There are two types of WAP security locks (PIN codes) for the WIM on SIM. The locks protect the subscription from unauthorized use when browsing. The locks should typically be supplied from the supplier of the SWIM.
Access lock An access lock protects the data in the WIM. The user is asked to
enter the PIN code the first time the SWIM card is accessed when establishing a connection.
Signature lock A signature lock is used for confirming transactions - like a digital
signature.
Push Services
These are useful for sending updated WAP site contents or WAP links to mobile users. Examples of services that can be implemented using push services:
•
Notifications about new E-Mails, voice mails, etc. Instant messaging and chat
• News, sport results, weather forecasts, financial information (stock quotes etc.)
•
Personal Information Manager (PIM) - delivery of contacts, meeting requests etc.
• Interactive games, e.g. play poker with a friend
There are two different forms of Push services, Service Indication and Service Loading. Reception of push messages and automatic load of URL (see below) may be turned on and off in the P800 user preference settings.
Service Indication (SI)
A Service Indication message contains a short text message and a URL. In the P800, these types of messages are typically stored in the WAP messages inbox which is integrated with the bookmark list in the browser application. When the user opens a message, both the text message and the URL will be displayed. The user have the options to postpone the message, load the URL or to delete the message.
Service Loading (SL)
A Service Loading message contains a URL. When such a message is sent to the P800, the URL will automatically be loaded into the browser application if the user is currently browsing the same site; otherwise it will be treated as a Service Indication message.
Opera Browser
Opera Software produces a fast standards-compliant browser for multiple platforms including UIQ. The Opera browser supports frames, javascript, plug-ins and much more whilst having a very compact code size. Opera has developed a technology called Small Screen Rendering which reformats full websites to fit the small screens of mobile devices without the need for scrolling. This technology resides in the browser and does not depend on any additional server capability in the network. Opera has demonstrated this technology on the P800 and is currently porting it to UIQ.

Symbian OS Operating System
Symbian is the company that developed the Symbian OS technology. Symbian OS is the operating system for Wireless Information Devices, and can be found in a wide range of PDA, ‘communicator’ and ‘smartphone’ designs. The Symbian OS technology delivers application and communication capabilities in a small package - it has a robust system kernel, powerful object­oriented middleware, industry-standard communication protocol suites, and an optimised implementation of Sun's Java smartphones and communicators.
The P800 is based on Symbian OS v7.0 and the established UIQ UI. Sony Ericsson and Symbian have been actively working with software developers for some time, and a range of UIQ-based applications have already been publicly demonstrated. Sony Ericsson is also an active participant in developer events such as the Symbian Developer Conference and Java One.
Third party applications may make use of the communications, display and storage facilities of the P800. Such applications may therefore be much more powerful than browser-based applications, enabling games to be faster and more exciting, for example. Applications from other PDA OSs and from the PC world may be expected to be ported across to the P800. Applications already available for Symbian OS (for example, on Psion products) may be ported by the supplier to run on the P800.
The P800 supports Java-based applications. Java technology is platform-independent, portable, modular and secure. Java applications are easy to develop, deploy and maintain. Because it supports both PersonalJava many applications written for handheld computers and mobile phones.
The P800 has 12 Mbyte user data space in which settings, user data and third party applications are stored. (9Mbyte on the P802). Applications are easily downloaded directly to the P800 using the browser, or may be installed from a connected PC.
Key consumer applications for the consumer include games, instant messaging, chat, information and entertainment. Corporate applications may be deployed, extending information access to the P800.
Open Environment
Applications may be written in both C++ and Java. Supported Java environments are PersonalJava

P800/P802
Java
Java is a widely used and extensible programming platform, which makes the development of personalized applications and content much easier. Originally developed by Sun in 1991, Java is a programming language used to develop applications – utility programs, games, plug-ins etc. – for different hardware and software platforms. Users of Java-enabled devices can install new applications and games to make their devices more personal and adapt them to specific needs.
Sun marketed Java as a “write once, run anywhere” concept, which at the time was a good description of Java’s strength. Simply put, Sun based the Java concept on two parts, the Java application and the Java interpreter, known as the Java Virtual Machine (JVM). A Java application cannot run by itself, it needs an interpreter that translates the code and runs the program. This was really the secret behind Java’s ability to work on various platforms. A developer could write an application without having to think about different computers and operating systems as long as hardware and software manufacturers included Java Virtual Machines in their products.
Even if “write once, run anywhere” still applies to some degree, the evolution of handheld computers and telecommunications forced Sun to adapt Java to the requirements of mobile devices with small displays and slow connections. This has led, among other things, to the development of PersonalJava and subsequently to Java 2 Micro Edition, (J2ME).
PersonalJava
PersonalJava, also known as pJava, is an edition of Java appropriate for mobile devices such as PDAs. It is suited to more powerful mobile phones and PDAs, such as the P800, and has a richer development environment and can interact more extensively with the P800 functionality compared to J2ME MIDP/CLDC.
PersonalJava was transferred into the J2ME platform in 1999, becoming the J2ME CDC/Personal Profile. However, CDC/Personal Profile has not really taken off yet and, pending its breakthrough, PersonalJava will still be a powerful option for years to come.
The P800 includes Symbian’s implementation of PersonalJava according to the Sun Microsystems ‘PersonalJava Application Environment Specification (PJAE)’ version 1.1.1, January 7, 1999. That version corresponds to a Sun JDK 1.1.7 implementation.
PersonalJava applications can make use of the following services:
• TCP/IP network communication
•
• JavaBeans support
• Virtual Keyboard and Jog Dial (up, down, select) input
•
• Time/Date sensing
•
PersonalJava applications are typically transferred to the P800 from a connected PC.
PersonalJava applications are used in FO mode. If the flip is closed, the application will receive an event and may choose to close or continue running in the background. There is no UI available in FC mode.

J2ME CLDC/MIDP
J2ME CLDC 1.0 (Java2 Micro Edition, Connected Limited Device Configuration, version 1.0) is an edition of Java aimed at small resource-constrained mobile devices where the runtime environment must fit into a few hundred kilobytes of memory (as compared to the 2.5Mb required for a typical PersonalJava environment).
MIDP (Mobile Information Device Profile) defines a programming API which has gained wide industry acceptance, and many MIDP compliant mobile phones are anticipated to come to market. A large number of applications for this environment is therefore to be expected.
The P800 supports this J2ME CLDC 1.0 / MIDP 1.0 environment. Applications may make use of the following services:
• Persistent storage (RecordStore class only – no access to the rest of the filing system)
•
J2ME canvas size is 208 x 172
• Touch Screen
•
Virtual Keyboard and Jog Dial (up, down, select) input
J2ME/CLDC uses a security model, often referred to as a sandbox. The sandbox includes a number of system components working together to ensure that untrusted applications cannot gain access to system resources.

MIDP applications can interact with arbitrary remote services that exist as a URL. Data may also be exchanged with remote devices that accept an HTTP or datagram connection.
Applications are typically downloaded from the mobile operator’s portal or the internet.
Applications are used in FO mode. When the flip closes, the instance of the Virtual Machine is not visible, but the user may return to the application by selecting it from the Application Launcher.

Personalisation and Customisation
The P800 may be personalised by the user and customised at the factory:
• By the User (via the UI, including interactive M-Services).
• By the User via PC-based utility applications.
•
Via Over The Air (OTA) configuration, initiated by operator, user or IT helpdesk.
• In the factory or at a Sony Ericsson Service Point, on behalf of a mobile operator.
User Personalisation
Wallpaper and Application Shortcuts
The user may set a static image to be the background ‘wallpaper’ for the FC standby screen. Image size is 208 x 144 pixels and formats JPEG, GIF, BMP, WBMP, MBM and PNG are supported. Larger images, for example, a 640x480 picture from the CommuniCam, will be resized to fit.
Wallpaper images may be selected from internal or Memory Stick storage. They can also be downloaded via M­Services, beamed in to the P800 using Bluetooth or Infrared, or transferred in over the PC link.
The application shortcut buttons may be personalised by the user. They will disappear after a short period to reveal more of the wallpaper image. Rotating the Jog Dial will redisplay them. They user may switch them on all the time.
Wallpaper is set in Control Panel, Display. A useful shortcut is to tap the battery icon select Settings. Wallpaper can also be set directly from a received MMS message.
in the FO Status Bar and
Screen Saver
A ‘screen saver’ image is displayed after a period of inactivity. The user can switch this facility on and off and select the delay period before the screen saver is displayed. Image size is 208 x 320 and format is the same as the Wallpaper image above, with the addition of support for animated GIF. Note that use of animated GIF increases power consumption. The top part of the image is displayed in FC mode and the entire image is displayed in FO mode.
Device lock may be used in combination with the screen saver. Upon pressing a button or touching the screen, the user will be prompted to activate keys and/or enter the device lock code.
When the screen saver or screen blanker is deactivated, the P800 will revert to the state it was in before the screen saver was activated.
76
P800/P802
Picture Phone Book
The user may store a picture of each person in Contacts. When an incoming call is received with CLI matching that contact, the contact’s picture will be displayed together with the other information. The contact’s picture is also displayed when making a call.
Pictures are easily taken using the built-in camera, though of course other images can be loaded in to Contacts. A copy of the picture is held in the Contacts database, therefore the original picture may be deleted or renamed without losing the copy stored in Contacts.
Ringtones
The user can add as many ringtones as desired, subject only to available file space. Ringtones may be collected from many sources including Memory Stick, M-Services,
Any compatible audio file in the multimedia storage (Internal or Memory Stick) can be selected as a ringtone. The P800 can play both iMelody format ringtones and the following polyphonic formats: AMR, AU, MIDI, RMF (Beatnik) and WAV.
A system default ringtone is provided. This is the ringtone when the P800 is first initialised. It cannot be deleted and is retained after a Master Reset.
The user may select a user default ringtone in the Phone application. In FO mode select Edit, Preferences, Sounds and alerts. This will now be played where no Personal ringtone is identified for the incoming call.
A Personal ringtone may be selected for a contact – simply select the required ringtone whilst entering or editing the contact’s details. When the Calling Line Identification (CLI) of the incoming call is matched to a contact, the Personal ringtone for that contact will be played.
Ringtones are played directly from the Internal or Memory Stick storage. Therefore, if they are renamed or deleted (using the Audio application), or located on the Memory Stick and it is removed, the P800 will instead play the system default ringtone.
The flow diagram on the next page illustrates the logic for ringtone selection when an incoming call arrives.
If no CLI information is available, then only a default ringtone can be played. If the user has selected a personalised default ringtone and it is available (can be read from the internal storage or Memory Stick) then it will be played, otherwise the system default will be played.
If CLI information is available, the P800 checks the Contacts database to find a contact with the telephone number in question. If a Personal ringtone has been set for this contact, it will be played. If the ringtone has been deleted, moved, renamed or exists on a Memory Stick that is unplugged, then the system default ringtone will be played.

P800/P802
Over-The-Air (OTA) Configuration
OTA remote configuration provides simple set-up of services. The user is spared the task of finding complex technical information and then manually entering it via the UI. Instead, a web request or a call to be the mobile operator’s helpdesk is all that is necessary – the appropriate settings can then be sent via SMS directly to the P800.
OTA configuration using the Ericsson/Nokia Over The Air Settings Specification enables the following parameters to be provisioned:
• WAP Account (Account name & WAP Gateway settings; Like a WAP Profile on the R380)
•
ISP Settings (Bearer information, username, password)
• Bookmark (name and URL)
•
SyncML settings
• MMS Settings
The following parameters may be remotely configured according to WAP Forum specifications:
•
WAP Account
• ISP Settings
Further OTA configuration is provided using Nokia Smart Messaging. It is used to set up E-Mail accounts, specifically:

P800/P802
BluetoothTM Wireless Technology
The P800 features built-in Bluetooth wireless technology. Its short-range radio link operates in the globally available 2.4 GHz frequency band, ensuring fast and secure communications up to a range of 10 metres.
Bluetooth wireless technology is designed to operate also in noisy radio frequency environments, providing reliable and high data throughput. To achieve this, techniques such as frequency hopping and error correction are used. To enforce data security, data can optionally be encrypted.
Bluetooth wireless technology facilitates instant connections, which are maintained even when the devices are not within line of sight. High-quality voice transmission is provided under adverse conditions, making it possible to use a headset connection to the P800 at all times.
Sony Ericsson is a founding partner of the Bluetooth Special Interest Group (SIG). Examples of Bluetooth wireless technology devices that are available now or are expected to be available in the near future include:
• Headsets for wireless voice transmission and remote call control
• PC cards for Bluetooth wireless technology in laptops and PDAs
•
MP3 music player
• Other phones for exchanging business cards, ring signals, playing games etc.
•
Digital still and motion video cameras
• Printers, hard disks and other storage devices
•
Handheld scanners for text, barcodes and images
Please note that restrictions upon the use of Bluetooth may exist in a few countries. Contact a Sony Ericsson representative to check if the use of Bluetooth is restricted in your country. If you are unsure, the Bluetooth function should be switched off until you know the possible scope of any restrictions.
Benefits of Bluetooth wireless technology in the P800
No cables Bluetooth wireless technology gives a true wireless connection to
headset, computers, networks, printers and other devices.
Radio Link Bluetooth does not require line-of-sight alignment. For example,
when using the P800 to connect a laptop to the internet, a Bluetooth link between the laptop and the P800 can be established even when the P800 is placed in a jacket pocket, or placed near a window for better (GSM/GPRS) reception
Several devices The P800 can maintain several devices, which you trust, in a
pairing list, enabling rapid and safe connection when those devices are in range
High transmission speed Comparable to USB.
Secure and fast Data connection with a Bluetooth PC/laptop turns the phone into a
modem for connecting to the Internet and for data transfer (no need to find and plug in cables or to align infrared sensors).
Synchronisation Fast synchronization of calendar and phone book with PC/laptop
and PDA.

Synchronization & Data Transfer
In everyday life, access to an updated calendar and details of friends and business colleagues is greatly appreciated. To be truly mobile, users must be able to carry their important information with them. Equipping mobile phones with Personal Information Manager (PIM) programs like calendars, task lists and address books gives users access to their most important data anywhere and anytime. The information is kept updated by synchronizing with the information at the office or at home. The growing use of groupware such as Microsoft
®
means that more and more meetings are booked electronically in daily business life.
Notes
The P800 uses the SyncML protocol for synchronisation. This means that it has compatibility to synchronise with a wide variety of devices over a number of different communications media.
SyncML – An Open Standard for Synchronisation
SyncML Background
Leading the way in providing remote synchronization capability, Sony Ericsson realizes that interoperability of remote synchronization is of utmost importance if mobile data usage is to become as widespread as generally predicted. That is why Ericsson, along with IBM, Lotus, Motorola, Matsushita, Nokia, Palm Inc., Psion and Starfish Software, founded the SyncML initiative in February 2000. Supported by more than 600 software and hardware developers, the SyncML initiative seeks to develop and promote a globally open standard for remote synchronization, called SyncML. Unlike many other synchronization platforms, SyncML is an open industry specification that offers universal interoperability. Because it uses a common language, called XML, for specifying the messages that synchronize devices and applications, SyncML has been called the only truly future-proof platform for enabling reliable and immediate update of data. The benefit for the end user is that SyncML can be used almost anywhere and in a wide variety of devices, regardless of application or operating system

What is SyncML?
SyncML is the common language for synchronizing all devices and applications over any network. SyncML leverages Extensible Markup Language (XML), making SyncML a truly future­proof platform. With SyncML any personal information, such as E-Mail, calendars, task lists, contact information and other relevant data, will be consistent, accessible and up to date, no matter where the information is stored. For example, a calendar entry made to a mobile device on a business trip is equally available to a secretary in a network calendar. SyncML is the ultimate choice for remote synchronization.
The P800 uses SyncML for both local synchronization (for example, with a PC using Bluetooth or a cable connection) and remote synchronisation over HTTP.
Designed for the requirements of the wireless world
SyncML is designed specifically with the wireless world’s tight requirements in mind. SyncML minimizes the use of bandwidth and can deal with the special challenges of wireless synchronization, such as relatively low connection reliability and high network latency. SyncML supports synchronization over WAP, HTTP or OBEX. As an open, future-proof standard, SyncML is the synchronization choice for any device or application of the mobile information society.

Network operators As multiple applications that need remote synchronization over
Today’s user of mobile devices probably uses a different synchronization product with every device. Each technology can synchronize only a few applications, or is limited to a particular type of network connection. This arrangement is expensive to install, confusing to configure and operate, and costly to administer. With SyncML, users will be able to buy devices that synchronize with a broader range of data.
Device manufacturers will benefit from a common protocol that will make the device interoperable with a broader range of applications, services, and network and transmission technologies
hosting are particularly concerned that a proliferation of synchronization technologies will make it impossible to deploy and support their customers in a cost-effective manner. To support the range of data types and devices in use today, service providers must install and configure multiple server infrastructures, maintain and support that infrastructure, and maintain compatibility and performance. The alternative now available, to use a single solution for data connectivity, involves the risk of a tight coupling to a propriety solution. With SyncML, they will be able to provide connectivity to a wider selection of applications.
an application to support more types of devices and networked data, but that choice comes at a cost. With SyncML, application developers will be able to develop an application that can connect to a more diverse set of devices and network data.

The P800 always synchronizes using SyncML, regardless of connection type. It connects via Bluetooth wireless technology, infrared or cable. The cable is connected either directly to the phone or to the desktop charger.
91
P800/P802
Automatic synchronization
Synchronisation can be configured to start automatically, given that a suitable synchronization program must be running on the other device:
•
When the USB cable is plugged in to the P800.
• When the P800 is placed in to the desk stand, and the desk stand is connected to the other device.
• When Bluetooth is activated on both devices and they come into operating range
•
When infrared is activated on both devices and the infrared sensors are aligned.
Intelligent process
A synchronization engine performs the task of synchronizing. For local synchronization, the synchronization engine is an application that runs on the desktop computer. The synchronization engine compares, updates and resolves conflicts to ensure that the information in the phone is the same as that in the computer.

GPRS, HSCSD and CSD Connections
The introduction of GPRS (General Packet Radio Services) is one of the key steps in the evolution of today’s GSM networks for enhancing the capabilities of data communication. Data traffic is increasing enormously (over both wired and wireless networks), with the growth in demand for Internet access and services paralleling that for mobile communications. Users want access to the Internet while they are away from their offices and homes, and surveys have found that the vast majority of business professionals want the ability to send and receive E-Mail, browse the Web and transmit text and graphics on a portable device. That is why the main applications driving Mobile Internet development are E-Mail clients and Web browsers.
The demand for high-speed Internet access will be the key driver for coming generations of wireless services, and GPRS can deliver the necessary speed. GPRS allows innovative services to be created, enabling new and previously inaccessible market segments to be addressed and increasing customer loyalty.
GPRS applications can be developed as both horizontal and vertical. Vertical applications are specific, including those for operations such as reaching police and emergency, taxi, delivery or automated services (vending machines, supervision, vehicle tracking). Horizontal applications are more generic and include those for Internet access, E-Mail, messaging, e-commerce and entertainment.
GPRS is able to take advantage of the global coverage of existing GSM networks. Applications developed for GPRS can be deployed on a large scale and can reap the associated benefits. GPRS also provides a secure medium for connections to private networks, banking and financial services.
The P800 supports connection to the internet, company intranets and mobile operator WAP services over GPRS, HSCSD and CSD. These will be explained in more detail later in this paper. A typical configuration will be to use GPRS for a continuous connection to the net. With GPRS, the P800 sends data in “packets” at a very high speed. The P800 remains connected to the network at all times, using transmission capacity only when data are sent or received. This enables E-Mail to be automatically fetched, whilst the browser is always available for immediate use. Third Party applications such as instant messaging clients will also benefit from a GPRS ‘always on’ connection.
Using the P800 as a Modem
The P800 contains a complete GSM/GPRS modem enabling it to be used to connect external devices such as laptop PCs to the internet or corporate intranet. The P800 is connected to the laptop using infrared, Bluetooth or cable, and will connect over the air using GPRS, HSCSD or CSD. Set Infrared status to Modem in the Control Panel to use this facility over infrared.
The P800 appears to the laptop like a normal modem, having an AT command set compatible with industry de facto extensions and ETSI 07.07. Note that SMS and SMSCB are not supported over this channel. A Windows modem driver file is supplied on the PC Suite CD-ROM.
95
P800/P802
Once paired with a Bluetooth-enabled laptop, the P800 is ready to make an immediate connection to the Internet or corporate network. Because Bluetooth is wire-free and requires no line-of-sight alignment, laptop can be positioned for maximum comfort whilst the P800 can remain in a jacket pocket, briefcase or even be placed up to 10 metres away to get optimal reception.
Infrared may also be used to link the P800 with other devices. Range is typically up to 1 metre. The two infrared ‘eyes’ must be kept in line of sight, at an angle of no more than approximately 30 degrees.
Or a USB cable may be used.

Technical Explanation of CSD, HSCSD and GPRS
This section provides an overview of the way data communication works in a GSM network environment. This will help you to understand the characteristics of the different solutions supported by the P800 and the parameters which govern the data transmission speeds available.
Circuit Switched Data (CSD)
A modem and landline is a common way to connect to the internet and company networks. The modem establishes a telephone call to the remote server which is ‘circuit-switched’, meaning that a telephone circuit is maintained for the duration of the connection, irrespective of whether data flows or not. The connection has a fixed bandwidth and is normally charged on a connected-time basis.
In GSM networks, this facility is widely available and is called Circuit Switched Data (CSD). It is very similar to using a modem, but is subject to lower data transmission speeds due to the connection taking place over the GSM wireless network. The standard speed of operation for CSD is 9.6kbps transmit and receive. 14.4kbps is available in some GSM networks. The P800 will operate at the higher speed where it is available.
Circuit-Switched Network Server
The above diagram shows an end-to-end overview of a circuit switched data call via the GSM network. When establishing a data call, the P800 will be connected via the GSM network to what you may think of as a ‘modem’ within the network, rather like the GSM network is acting as a
97
P800/P802
wireless RS232 cable. The modem makes a PSTN or ISDN call to the Point Of Presence telephone number of the required resource, for example your Internet Service Provider or company modem pool for intranet access. Since the modem in the GSM network operates to common standards, no special configuration is required at the ISP or company remote access servers. The limitation on transmission speed (9.6kbps or 14.4kbps) is due to the lower bandwidth of the wireless connection from the P800 to the modem.
As well as making data calls itself (built-in E-Mail, browsing and other applications), the P800 may be connected to a PC using USB cable, infrared or Bluetooth. In this case it acts like a modem. Either way, a standard CSD call Is limited to 9.6kbps or 14.4kbps.
High Speed Circuit Switched Data (HSCSD)
HSCSD operates in a similar manner to CSD, but allocates more radio capacity between the P800 and base station in order to increase the overall speed of the connection. Some explanation of the GSM system will help explain the characteristics of HSCSD.
A GSM mobile phone making a voice call will digitise the speech into a very efficient compressed data stream. One radio channel has enough capacity to carry 8 of these data streams, so the channel is divided into 8 repeating timeslots. The phone is allocated a radio channel and timeslot and will send the data stream in bursts over that channel. Other phones in the cell may make use of the other timeslots in the channel. A separate receive channel and timeslot is allocated and works in the same way.
When making a CSD call, the data is similarly sent in bursts over one of the 8 timeslots in the transmit channel. The basic data rate of this transmission is 9.6kbps, but some networks are upgraded to a data rate of 14.4kbps.
98
P800/P802
In the above example, terminal A is a phone using one timeslot for a voice call, terminal B is a P800 using one timeslot for a CSD data call and terminal C is a phone using one timeslot for a CSD WAP session. In each case, the timeslot is allocated whether data is transmitted or not.
In order to achieve higher data rates, the GSM terminal may be allocated more timeslots within the transmit and receive channels. Since common applications such as browsing benefit from having high data receive rates without requiring high transmit rates, HSCSD configurations are typically asymmetric, meaning that data speed in one direction (receive) is higher than the data speed in the other (transmit). This also saves battery life.
The slot allocation and hence the speed is set by the GSM network when the call is initiated, and may be dynamically altered depending on network conditions such as the number of active users in each cell. In the above example, the P800 (terminal B) has been allocated 2 receive timeslots.
The HSCSD maximum data rates (kbps) using the P800 are shown below.
9.6kbps per timeslot
14.4kbps per timeslot
Rx 19.2 28.8 Tx 9.6 14.4
The timeslot usage is not linked to demand from applications – an HSCSD connection will be maintained even if no data is flowing. The data ‘pipe’ is (as far as practicable) maintained fully open for you whether data flows or not. HSCSD connections are typically charged by connection duration in the same way as CSD calls.
99
P800/P802
Here is a summary of the slot usages in HSCSD. One ‘uplink’ and 1 to 2 ‘downlinks’.
Analogue and ISDN (V110) Bearer Service Types
CSD and HSCSD are capable of Analogue and, where supported by the mobile operator, ISDN connections. ISDN offers faster call set-up time and can increase the performance of an HSCSD connection due to the limitations in analogue modem technology. The simplest option is to test ISDN bearer mode, and switch to analogue if no connection can be made. Note that due to network limitations, analogue is often the only bearer that works when the user is roaming.
GPRS
GPRS mode combines the speed advantages of multi-timeslot working with packet data efficiency. Instead of utilizing a constant stream of timeslots in a circuit-switched call, GPRS mode sends/receives data in small packets, as needed, much like IP on the internet. Capacity is only used when data is being sent or received, which means that it is possible to be “constantly” connected so that applications have immediate access to networked servers. The radio resources are shared between users in a much more efficient way than is possible using circuit-switched methods – timeslots are dynamically allocated to those users who are transmitting and receiving data. The service is typically charged by the amount of data transferred.
Connection set-up is fast and the P800 will normally be left connected for the whole time it is switched on. When applications need to transfer large amounts of data such as files, images etc, it is possible to increase bandwidth by using more timeslots for the duration of the transfer. The P800 supports up to 4+1 timeslots receive + transmit. The GSM network will dynamically allocate timeslot resources depending on current network conditions.
