Key functions and features
White Paper
This phone is the next st ep in i magi ng for Sony Ericsson products. The evolution of mobile communications towards imaging will greatly increase the scope for new applications and services. In the area of multimedia in mobile phones, Sony Ericsson can show its vast experience in consumer electronics and entertainment – music, pictures and games – as well as its mobile technology leadership.
EDGE
EDGE (Enhanced Data rates for Global Evolution) enhances all the benefits of GPRS by providing significantly higher data rates. In addition, services are made feasib le by EDGE th at requ ire more b andwi dth and speed than GPRS can offer. Altern atively, the added bandwidth can be used as capacity for additional customers. Higher data rates are achieved using new modulation schemes on the air interface.
Device Management
The Z500a supports Open Mobile Alliance Device Management (OMA DM) which allows for the remote configuration and updating of settings for purposes such as web browsing and synchronization. Service providers benefit because OMA DM allows for efficient reconfiguration of phones in the field without requiring consumers to visit a retail location or call a customer servic e representative. Netwo rk changes such as new IP addresses can quickly be configured in numerous devices. Consumers benefit because the manual effort needed to modify settings can be avoided.

3D Games
The Java 3D gaming software introduces and supports cutting edge 3D graphics. Audio developments
such as 40 tones polyphonic sound and force feedback provide a much richer experience. With operator support, there is the possibility for multiplayer games to play against friends. The large 1.8” STN display can only add to a lasting gaming experience. Downloading graphic intensive games requiring up to 6 MB user memory is also possible with that amount of built-in mem ory.
Java™ 2 Micro Edition
With Java, you can download extra content, for example, new information- an d entertainment -based application s. This gives use rs a chanc e
to personalize the functions and features in their phones, and developers the opportunity to create new applicatons.
Gaming
Gaming is already a very popular
feature in mobile phones, and with
Java, users can add new games and
skill levels to further enhance the entertainment value of Sony Ericsson phones.
Copyright protection – DRM
DRM (Digital Rights Management) assures the rights and copy protection of downloaded content (audio, pictures, ri ngt ones , vi deo , ent er ta inment features such as games etc.).
Content-based services have great market potential, and to encourage this, Sony Ericsson plans to support DRM in all future multimedia products. Sony Ericsson regards DRM as a key enabler for content-based services, and is active in supporting the ongo ing sta nda rdi zation work of the OMA (Open Mobile Alliance). Furthermore, any additional market requirements for DRM will be monitored.

File management
There is a file manager, similar to that which can be found on many computers. In the file manager the user has an overview of the contents of the phone as well as how much memory is allocated to each function and feature.
GPRS (General Packet Radio Service)
GPRS offers the user the speed needed for satisfactory mobile Internet usability. The phone supports GPRS (Class 10 meaning 4+2 sum 5).
WAP 2.0 supporting XHTML™
The WAP browser supports the markup languages of WAP 2.0 – XHTML Mobile and XHTML Basic. These two subsets of the Web standard XHTML are supported by all major Web browsers. An XHTML page can be viewed in both the WAP browser and in any standard Web browser. All of the basic XHTML features are supported, including text, images, links, check boxes, radio buttons, text areas, headings, horizontal rules and lists.
In addition to XHTML, the WAP browser supports WML. The user can navigate between WML and XHTML pages. WAP 2.0 also supports cookies, often used by Web sites to stor e sit e-spec ific in format ion in th e browser between vi sits to th e s ite. Coo kies a re oft en use d by e-commerce si tes (in shoppin g ca rt s and wish lists for example), and to save the user from entering the same information more than once.
On the Web, the de facto standard style she et la ngua ge is Cascading S tyle Sheet s (CSS), s pec ifie d by the W3C and implemented in IE, Netsca pe, and Opera. For mobile phones, the OMA has identified a subset of CSS and extended it with OMA specific style rules. The CSS subset and the OMA extensions are called Wireless CSS (WCSS). The WAP browser supports WCSS 1.1
Instant messaging (Wireless Village)
To ensure interoperability of mobile instant messaging and presence services, Sony Ericsson, Ericsson, Motorola and Nokia have created the Wireless Village Solution, an open standard. The protocol is bearer­independent and can be implemented in different networks. The Wireless Village Instant Messaging and Presence Service (IMPS) includes three primary features:
Presence
Presence information of other Wireless Village users is received and displayed to indicate their willingness to communicate. The user’s own presence information is also sent for othe rs to view. If the user is interested in another person’s presence status, he or she can search fo r this person. If the person is found , the user may sub scribe to his/her presence information. The presence information is displayed in a contact list.
Instant messaging
Instant messaging means “point-to-point messaging” between Wireless Village users. Messages can be sent to an entire contact list or to a single user. Short message histories of the communication are filed.
Groups
The user may join a chatroom and chat with the other participants/members.
Cascading style sheets (CSS)
Before style sheets were introduced on the Web, developers had little cont rol over the presentat ion of thei r Web pages. An XHTML document specifies the structure of the content, wh ich part is a paragraph, which part is a heading, and so on. It does not specify how it shall be presented. Browsers use a default presentation for documents without style sheets. By adding a style sheet to the document the developer can control the presentation of the document, the colors, fonts, and layout.
Email
With inbox, outbox, save draft and reply options, you have all the functions you need for effective email communication in a powerful mobile phone. Constantly connected to a POP3, SMTP or IMAP4 email server anywhere on the Internet, your phone stores messages dynamically, depending on available memory, and updates your inb ox aut omatic ally and over t he air. Check your email anywhere. Reply to email on the move. Friends, family and business contacts know that when they send you email, you can receive, read and act on it immediately. Y ou can i nclude pi ctures i n outgoing e mails and receive attachments. Hyperlinks in emails are supported.
Z500a
Personalization
With themes, the user can change many settings in the phone, for example colors, images and ringt ones, making it more personal. The phone comes with a number of preloaded themes and pictures, and more can be downloaded and exchanged – sports, movie, seasonal and other themes will be available on Sony Ericsson or operator sites. Other personalizable features are the start­up picture and the screen saver. Specific pictures and ringtones can also be set for each separate name in the phonebook.

Technologies in detail
Entertainment
Media player
The Media player supports different audio and video formats, streaming as well as download and playback.
Music
The Media player is a multi-format digital audio player which enables the user to carry and play a selection of favorite songs. A range of audio formats are supported:
•MP3
MP3 is the file extension for MPEG audio layer 3. Layer 3 is one of thr ee c odi ng schemes (la yer 1 , l ay er 2 and layer 3) for the compression of audio signals. Layer 3 uses a very efficient compression method, removing all i rrelevant pa rts of a soun d signal tha t the human ear cannot perceive. The result is, for exam­ple, CD digital audio (CDDA) convert ed to MP3 with almost untouched quality, compressed by a factor of around 12. The high compression of audio in MP3 files makes them relatively small, though MP3 files can be crea te d wi th different size and quali t y co m pro -
mises. The smal l fi l e si ze, t oge the r w i th t he ex cellent sound quality, are the main reasons for the MP3-for­mat’s huge popularity.
•MIDI Musical Instru ment Digital Interface. Unlike the other formats, MIDI is not a recording of music, but a de scription whic h e nabl es a local sy nth e­sizer to play the music from the inst r uct ions included in the MIDI file. Since a MIDI file only represents player information, it is far more concise than for­mats that store the sound directly. An advantage is very small file sizes. MIDI is one format used for polyphonic ringtones.
•AMR Adaptive Multi Rate. A medium quality co mpress ed sound format.
White Paper
Z500a
Songs may be stored in the internal Z500a user memory. The folder syste m enabl es the user to orga nize s ongs int o groups and create simple playlists of MP3 songs.
Songs may be collected in numerous ways, including Internet download and file transfer from a PC.
The Med ia player is intelligently aware of other applications in the phone:
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 application, providing music while using other applicat ions su ch as the phone book or ca lendar, or playing games.
Polyphonic ringtones
Background
The word “polyphony” me ans produ cing sev eral t ones at the same time. Almost all music that we listen to consists of polyphonic melodies.
Early Ericsson mobile phones supported a proprietary non-polyphonic format called eMelody. Due to the musical limitations of eMelody, and the popularity of creating, sending and downloading ring melodies, Ericsson and Sony Ericsson, tog eth er with other manufacturers, created the more advanced non­polyphonic sound format – iMelody.
A MIDI signal or file does not contain any music. It contains binary data (information) of how a melody is played and when this data reaches a synthesizer, the synthesizer will transla te the binary data to music, w hen connected to an a mpli fier with sp eakers so tha t the s ound becomes audible.

The Media player supports download and playback of MPEG-4 and H.263 formats for viewing video clips in the phone.
Video clips may be downloaded from the Internet or copied from a connected PC. Video files are large compared to still images (roughly 1 MB per 1 second of video).
Files must be of types MP4 or 3GP, having video encoded in MPEG-4 Simple Visual Profile and audio in AAC or AMR format. Video may also be encoded in H.263.
MIDI – Musical Instrument Digital Interface – is a specification for a communications protocol principally used to contr ol elect ronic mu sical in struments . The MID I files are small, and perfect for mobile devices, which have limited storage capacity. MIDI is today a well known standard used by many musicians, composers, arrangers and so on.

MMS completes the potential of messaging. Sending digital postcards and PowerPoint-style presentations is expected to be among the most popular us er application s of MMS. Eagerly awaited by young users in particular, MMS is projected to fuel the growth of related market segments by as much as 40%.
Multimedia Messaging uses WAP (Wireless Application Protocol) as bearer technology which can also be powered by the high-speed transmission technology EDGE/ GPRS. This allows u sers to sen d and receive messages that look like PowerPoint-style presentations. 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 ben efits at every level and to every kind of user.
OTA configuration
Users can easily get MMS into their phone. MMS supports OTA, meaning that the user does not have to configure the settings manually. The configuration is done by the operator.
Auto-exposure c ontrol
The camera has a fully automatic exposure control that selects the optimal exposure time needed to get an excellent picture. The exposure time is automatically adjusted whenever changes occur in the viewfinder.
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 messa ge is ab out 200 Kb ytes ( limit ed by both the mem ory capability of the mobile phon e and less than ideal network conditions), enabling much richer MMS content. Comple te wi th wor ds, sound s and ima ges, MMS content is endowed with the user’s ideas, feelings and personality. An MMS message can contain one or more of the following:
Text
As with SMS and EMS (Enhanced Messaging Service), an MMS message can consist of normal text. The length of the text is unlimited. The main difference between an EMS and MMS m e ssage is that in an MMS message, text can be acco mpani ed no t only by simp le pixel ima ges or melodies but by photographic images, graphics, audio clips and video clips.
Templates
The phone comes with a number of MMS pre-defined templates, for exa mple temp lates for birthday c ards, meeting requests etc.
Audio
MMS provides the ability to send and receive audio as part of messages. The phone supports iMelody, MIDI, and AMR formats. Not only can users share a favorite song or ringtone with a friend, they can also use the mobile phone to record a sound or message and send it along with a text message. As sound includes speech as well as music, this extra dimension to an MMS message allows for a spontaneous and immediate personal

expression in communication messaging. Rather than sending a downloaded birthday jingle in EMS, a user can, for example, send a clip of his or her own personal rendition of “Happy Birthday”.
Pictures and themes
By using the integrated camera, users can take a picture and immediately send it to a recipient. The ability to send pictures is on e of th e mos t exci ting a ttri butes of MMS, a s it allows users to share meaningful moments with friends, family and colleagues.
Mobile picture transmis sion also offers inestimable utility in business applications, from sending on-site pictures o f a co nstru ction proje ct t o capt uring and st oring an interesting design concept for later review. Editing a picture by adding text allows users to create their own electronic postcards, an application that is expected to substantially cut into the traditional postcard market.
Themes (downloaded or pre-defined) can be exchanged via MMS.
PIM communication with MMS
By using MMS, it is easy to handle PIM (Personal Information Manager) information. The user can send and receive bus iness cards ( vCard) , cal endar e ntrie s su ch as appointments (vCal) and notes (vNotes).
Streaming content in MMS
Streaming makes it possible to view files as they are being downloaded to the pho ne. The MPEG-4 file for mat can be used for continuous media along the entire delivery chain envisaged by the MMS, independent of whether the final delivery is done by streaming or download, thus enhancing interoperability.
In particular, the following stages are considered:
Benefits with MMS
By allowing the mobile phone to serve as an image processor and conv eyor, 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.
As MMS uses WAP as its bearer technol ogy and is being standardized, it has wide industry support and offers full interoperability. This is a major benefit to service providers and end users. Gradual steps in messaging evolution and the conti nui ty of user experience has resulted in an ease -of -use where interoperability is assured.
The MMS server, through which MMS messages are sent, supports flexible addressing (to both normal phone numbers (MSISDN) and email accounts), which makes the user interface more friendly and allows greater control for operators. The MMS server, moreover, is responsible for the instant delivery feature of MMS.
MMS technical features
The MMS standard, just like that of SMS, offers store­and-forwar d transmi ssion (i nstan t deliv ery) of m essage s, rather than a mailbox-type model. MMS is a person-to­person communications solution, meaning that the user gets the message directly into the mobile phone. He or she does not have to call the server to get the message downloaded to the mobile. Unlike SMS, the MMS standard uses WAP as its bea rer pro tocol. MMS wil l take advantage of the high speed data transport technology EDGE/GPRS and support a variety of image, video and audio formats to facilitate a complete communications experience.
Upload from the originating terminal to the MMS proxy.
File e xchange between MMS servers.
Transfer of the media content to the receiving termi­nal, either by file download or by streaming. In the first ca se, the self-contained file is transfe rred, whereas in the second case the content is extracted from the file and stre amed accordi ng to open payl oad formats. In this case, no trace of the file format remains in the con t ent that is transmit ted over t he wire or over the air.
Additionally, the MPEG-4 file format can be used for storage in s er ver s and the “hint t rac k” m e chan ism can be used to prepare for streaming.
Architecture
The MMS Center (MMS-C) is comprised of the MMS Server, the MMS Proxy-Relay and the MMS Store. The MMS Center is th e cen tr al ele me nt of th e MMS net w or k architecture, providing storage and operational support, enabling instant delivery of multimedia messages fro m terminal-to-terminal and terminal-to-emai l, and supporting flexible addressing. The center’s MMS Proxy-Relay interacts with the application being run on the MMS-enab led te rmi nal to provi de vari ous m essagi ng services. WAP is used as the bearer of an MMS message between the MMS-C and the MMS client (application). The WAP Gateway is used for delivery and retrieval of messages.

Advantages of GPRS/EDGE
Using GPRS and EDGE has many advantages, for example:
Constant connection Keep an open connection to the company network. All connection settings can be managed by using the
subscriber preferences, operator constraints, and billing information. The MMS-C also vouches for high quality messaging, for example by format conversion. This means that the MMS-C recognizes which fo rmats are supported in the mobile phone, and adapts the MMS messages to these for m at s.

WAP over GPRS Access the Internet via WAP at hi gh speed and with a constant connection.
Email over GPRS Remain connected to an email system while reading and preparing messages, (which are then sent at high speed).
Data communication Transfer data and access the Internet or an intranet
GPRS
The introductio n of GP RS was a big step i n the evo luti on of the GSM networks for enhancing the capabilities of data communication. Data traffic has increased (over both wired and wireless networks), with the growth in demand for Internet access and services paralleling that of mobile communications.
We can now see that the demand for high-speed Internet access is the key driver for coming generations of wireless multimedia and entertainment services.
with a PC, PDA or handheld device connected via cable.
Provide settings Receive GPRS configuration settings from the pro­vider OTA (over the air), making manual configura­tion unnecessary.
User-controlled settings Take advantage of full user control in the data con­nections menu, est ablishing m ultiple des criptio ns and accessing advanced settings for GPRS.
Instead of occupying an entire voice channel for the duration of a data session, the Z500a sends and receives data in small packets, as needed, much like IP on the Internet. Thank s to this, th e phone is always onli ne, using transmissi on capacity only whe n da ta is sent or rec eiv ed. The phone is compa tible with GPRS R99.
The GSM system l imits the ability to use all ei ght time slots, so the ph one use s up t o four tim e sl ots f or re ceivi ng data, and one slot for transmitting.
GPRS is able to take advanta ge of the global co ver age of existing GSM networks. Applications developed for GPRS have been deployed on a la rge scale an d have thus reaped the assoc iated benefits.
With GPRS, the Z500a sends data in “packets” at a high speed. The Z500a remains connected to the network at all times, using transmission capacity only when data is sent or received.
EDGE
EDGE (Enhanced Data rates for Global Evolution) provides all the benefits of GPRS at significantly higher data rates and enables feature-rich services that require higher data rates than GPRS can deliver. The added bandwidth can also be used to increase capacity for additional customers.
The higher data rates are achieved with the use of new modulation schemes on the air interface. Several of the new modulation schemes use 8-PSK modulation rather than the GMSK modulation used by GSM and GPRS.
Phone identity in formation and character i stics of the connection are described in the PDP (Packet Data Protocol) context. This information is stored both in the phone and in the mobile network, so that each phone is identified and “visible” to the system.
The new modulation sche mes m ay re qui re an upgr ade to the RF hardware in all base stations and new mobile stations such as the Z500a. In addition, new re­transmission procedures and packet data channels are introduced with the associated signaling. The Z500a is a class B mobile station meaning it can monitor circuit switched and packet switched services simultaneously but can utilize only one of the services at a time. In addition, it is 8-PSK power class 2 meaning the nominal maximum output power is 27 dBm i n t he GSM 850 band and 26 dBm in the GSM 1800 or 1900 bands (see 3GPP TS45.005).
