Key functions and features

Multimedia Messaging - Digital greetings

Reacting to the enormous popularity of mobile phone messaging, Sony Ericsson has incorporated the latest messaging standard into the T300/T302, along with a colour display for an enhanced imaging experience.

T300/T302 users can share ring signals, and download them from the Web.

Early Ericsson mobile phones supported a proprietory non-polyphonic format called eMelody. Due to the musical limitations of eMelody, and as it became popular to create, send and download ring melodies, Ericsson and Sony Ericsson, together with other manufacturers created the more advanced nonpolyphonic sound format - iMelody.

The development from the iMelody format to the MIDI format means a revolution to the sound quality. The MIDI files are small, and perfect for mobile devices, which has limited storage capacity.

MIDI - Musical Instrument Digital Interface - is a specification for a communications protocol principally used to control electronic musical instruments. MIDI is today a well known standard used by musicians, composers, arrangers and so forth.

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 synthesiser, the synthesiser will translate the binary data to music, when connected to an amplifier with speakers so that the sound becomes audible.

Say it in words, say it with pictures, animate it, add sound. Multimedia birthday and holiday greetings are great fun to put together using the T300/T302. On vacation, use your mobile phone and accessories to send a digital postcard with stylized text, digital pictures of where you are, and authentic sound clips to friends and family back home. If, when shopping, you find something a friend might like, you can instantly send a digital picture of the item and ask if they like it.

With MMS, the subscription applications get more interesting, for example stock information, movie trailers and weather reports.

Polyphonic ring signals

Pleasing to the ear, polyphonic ring signals play several tones simultaneously making a more musical sound. The word “polyphony” means playing with several tones at the same time. Almost all music that we listen to consists of polyphonic melodies. Up to now, the majority of the GSM mobile phones doesn’t support polyphonic sounds and ringsignals.

Please visit www.midi.org for more information.

Downloadable games

Gaming is already a very popular feature in Sony Ericsson phones. Now the mobile Internet portal offers the possibility of downloading games. Net work operators may also offer games download to their customers as an added value offer. Users can add new games and skill levels to further enhance the entertainment value of Sony Ericsson phones.

T300/T302 games download is made possible by a true virtual machine. The Sony Ericsson portal for downloading of free games for the T300/T302 is accessible with only one key press in the games menu. The openess of the downloadable games solution is dedicated to provide an enhanced gaming experience.

T300/T302

White Paper, August 2002

The downloadable games can fully take advantage of the phone´s interfaces, such as TCP/IP, SMS, vibrator and backlights. The virtual machine executes the downloading of games for the optimal game experience. The user can download an unlimited number of games as long as the file system allows it, i e until the phone memory is full.

The downloading concept includes certification of the games, which makes it possible to create a revenue chain and favourable business opportunities for network operators and content providers. The virtual machine uses true sandbox technology for highest level of security.

The software development kits are available via www.mophun.com

Imaging

With a digital camera attached to your T300/ T302, you can take, view, store and send highquality pictures over the air to another mobile phone, as MMS messages, or you can send them to an e-mail address or Web photo album. Downloading images from the Web is another alternative. Thousands of online image collections already exist on the Web and many sites are already gearing up to include images for use in mobile phones.

There are various ways to incorporate images and other multimedia into your communication. You can attach pictures to people listed in your phone book and have pictures or icons of the caller identifying them in your display.

In addition to XHTML, the WAP browser supports WML. The user can navigate between WML and XHTML pages.

WAP 2.0 in the T300/T302 also supports cookies, often used by Web sites to store site-specific information in the browser between visits to the site. Cookies are often used by e-commerce sites (shopping carts and wish lists), and to save the user from entering the same information more than once.

Full graphic 256 colour display

The large colour display of the T300/T302 enhances viewing, facilitating high-quality multimedia messaging and personalized imaging. The standby display looks like the desktop in a computer, with the menus presented as icons.

Joystick navigation

The T300/T302 has an easy-to-use 5-directional joystick function. Using finger or thumb, you can easily navigate the new T300/T302 menu system. When you arrive at the required function in a menu, instead of pressing Yes, just gently press the joystick and the feature is activated. The T300/T302 MMI is adapted for easy joystick navigation.

The pictures are stored in the picture browser in the phone. From here, the user can select view, thumbnail or full view, as well as keep track of the number and size of the pictures stored in the phone.

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, checkboxes, radio buttons, text areas, headings, horizontal rules and lists.

GPRS

GPRS uses Internet-style packet based technology. It lets you be permanently connected to the mobile Internet, but only uses the radio link for the duration of time that it transfers data. GPRS offers the user the speed needed for satisfactory mobile Internet usability. The T300/ T302 supports GPRS 3+1.

T300/T302

White Paper, August 2002

More in-phone functions

E-mail

The T300/T302 is one of the first mobile phones on the market with a built-in fully functional email client. With inbox, outbox, save draft and reply options, you have all the functions you need for effective e-mail communication in a small and powerful mobile phone. Constantly connected to a POP3, SMTP or IMAP4 e-mail server anywhere on the Internet, your T300/T302 stores messages (without attachments) dynamically, depending on available memory, and updates your inbox automatically and over the air. Check your e-mail anywhere. Reply to email on the move. Friends, family and business contacts know that when they send you e-mail, you receive it and can read it and act on it immediately. You can include pictures in outgoing e-mails, but not receive attachments. Hyperlinks in e-mails are supported.

EMS (Enhanced Messaging Service)

You can send text, pictures and sounds in easyto-create and fun messages. EMS has been adopted by several leading mobile phone manufacturers, making it possible for T300/T302 users to send enhanced text messages to users of other makes of mobile phones. EMS makes it possible for the user to use text formatting (style, size, alignment and paragraphs) in a text message. At purchase there are several predefined images and animations in the T300/ T302.

Predictive Text Input Software

Text messaging with your T300/T302 is made easier than ever with the introduction of predictive text input software. Instead of having to press keys several times for a letter, software in your T300/T302 chooses from a dictionary of words and phrases and anticipates what word or phrase you are writing, giving your mobile phone keyboard ease of use comparable to that of a full-size keyboard.

Screen saver and sleep mode

The screen saver is activated when the phone has been idle for 26 seconds. There is a predefined screen saver at the purchase of the phone, but the user can choose his/her own image/animation as a screen saver. After a short period of time the screen saver changes to sleep mode, to save power.

Memory management

All applications in the T300/T302 share the same memory, allowing for efficient memory usage. When the memory runs low, the user gets information about the current memory situation, where each application’s usage is displayed. In the memory manager menu, the user can delete items from any application, in order to set memory free. The memory available for the user is approximately 400 kBytes.

Mobile chat

Mobile chat makes text messaging easier, since a chat-session opens up immediately when a text message is received from a phone. Because the user stays connected during the session, the messages open up automatically. All previous messages from both persons are visible on screen, each writer being distinguished by a nickname.

Picture phone book

The phone book in the T300/T302 lets the user assign a picture or a personal ring signal to a certain phone number. When the user gets a call from this person, the picture (instead of the number) is shown in the display.

Events

The T300/T302 Events feature keeps track of important meetings that you need to attend, phone calls that you need to make or tasks that you need to do. 20 items can be saved. You can also choose to add, reschedule, edit, send or delete events.

iMelody and Melody Composer

The audio iMelody format enhances the sound quality in the T300/T302. With this format, the user can play, compose, edit and send melodies within the improved Melody Composer. The composer has an improved graphical user interface to simplify melody handling. All new and edited melodies are stored in the iMelody format.

Sound browser

From the Sound browser function, the user can handle all sounds (for example MIDI, eMelodies, iMelodies and sound recordings) stored in the phone. The user can play, send and view information on the sounds. Ring signals (MIDI, eMelody, iMelody, vMel) can be downloaded via WAP or exchanged via SMS (iMelodies), infrared and MMS (MIDI, iMelodies). Sound recordings can be exchanged via infrared and MMS. The maximum number of sounds is limited only by the amount of free memory.

Please also see information about the MIDI format under “Polyphonic ring signals” on page 4

Camera application

The camera application in the T300/T302 supports the Communicam MCA-25. The user can browse, view, send and store pictures in the phone. It is also possible to set different picture sizes.

T300/T302

White Paper, August 2002

Themes

With themes, the user can change the appearance of the display, for example, the text, the background colours and the background picture. The phone comes with a number of predefined themes. It is possible to download and exchange additional themes. The maximum number of themes is limited only by the amount of free memory.

T300/T302

White Paper, August 2002

Multimedia in the T300/T302

The T300/T302 is a multimedia phone. The colour display together with the audio functionality gives the user several multimedia possibilities. For example, sounds can be recorded and stored. By using themes, it is easy to change the appearance of the display. Pictures, audio, animations and themes can be transmitted via MMS.

Graphics

Graphics (tables, charts, diagrams and layouts) has a major impact on the way we work. The T300/T302 supports JPG (max 640x480), GIF (max 160x120), WBMP (max 320x320) and animated GIFs. With MMS, the user can personalize the appearance of the display — for example the text, the background colours and the background picture.

Themes

With themes, the user can change the appearance of the display, for example the text, the background colours and the background picture. The phone comes with a number of predefined themes, and it is possible to download additional themes. The maximum number of themes is limited only by the amount of memory.

Image formats

For information on Image formats and downloading of images, see “Image format technical data” on page 64 and “Images — downloading to phone” on page 64.

Audio

The user of the T300/T302 can use the mobile phone as a sound recorder. With the sound recorder function, it is easy to make a voice recording, for example a personal rendition of “Happy Birthday”. The audio function in the T300/T302 also allows downloading of sounds and melodies.

Pictures

With a digital camera attached to your T300/ T302, you can take, view and store pictures. It is also possible to download colour pictures to your T300/T302. The pictures are stored in the picture browser in the phone. From here, the user can select view, thumbnail or full view, as well as keep track of the number and size of the pictures stored in the phone.

The pictures stored in your T300/T302 can be used for creating your own digital postcards. This is easily done by adding text to the pictures and sending them via MMS.

MMS (Multimedia

F m

Messaging Service)

One of the key features in the T300/T302 is the Multimedia Messaging Service (MMS), expected to become the preferred messaging method of mobile terminal users, since there are virtually no limits to the content of an MMS transmission. An MMS message from the T300/T302 can contain text, graphics, animations, images, audio clips and ring melodies. For more detailed information, see “Multimedia Messaging Service” on page 51. For third-part developers’ information, please visit www.SonyEricsson.com/mobilityworld/ and look for the MMS Developers’ guidelines.

Defined and specified by 3GPP as a standard for third generation implementation, MMS completes the potential of messaging. Sending digital postcards and PowerPoint-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 by as much as forty percent.

Using the Wireless Application Protocol (WAP) as bearer technology and powered by the highspeed transmission technologies EDGE, GPRS and UMTS (W-CDMA), Multimedia Messaging allows users to send 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 benefits at every level and to every kind of user.

T300/T302

White Paper, August 2002

igure 1. An MMS message can contain images,

usic, audio and graphics.

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. That is why the key word to describe MMS content is rich. Complete with words, sounds and images, MMS content is endowed with the user’s ideas, feelings and personality. There is however a storage limit of 20 MMS messages, which is independant of available memory. And whether the messages are full or only notifications is insignificant. An MMS message can contain one or more of the following:

Te xt

As with SMS and EMS, an MMS message can consist of normal text. The length of the text is unlimited, and it is possible to format the text. The main difference between an EMS and MMS message is that in an MMS message, text can be accompanied not only by simple pixel images or melodies but by photographic images, graphics, audio clips and in the future, video sequences.

Te mp la te s

The T300/T302 comes with a number of MMS pre-defined templates, for example templates for birthday cards, meeting requests etc.

T300/T302

White Paper, August 2002

Audio

MMS provides the ability to send and receive full sound (iMelody, MIDI and AMR) messages. Not only can users share a favourite song ot 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 and themes

By using either a digital camera attached to the T300/T302 with a cable, or a snap-on camera accessory, users can take a snapshot and immediately send it to a recipient. 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.

PIM communication with MMS

With MMS in the T300/T302, it is easy to send and receive business cards and events.

Business card (vCard)

With MMS in the T300/T302, the user can send his/her business card.

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. 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-sending market.

Themes (downloaded or pre-defined) can be exchanged via MMS.

SMIL presentations

SMIL stands for Synchronized Multimedia Integration Language and is pronounced “smile”. SMIL in the T300/T302 allows the user to the create and transmit PowerPoint-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 Powerpoint-style 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

Figure 2. Example of the creation of an MMS message.

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.

T300/T302

White Paper, August 2002

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 technical features

The MMS standard, just like SMS, offers storeand-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. Unlike SMS, the MMS standard uses WAP as its bearer protocol. MMS will take advantage of the high speed data transport technologies EDGE and GPRS and support a variety of image, video and audio formats to facilitate a complete communication experience.

Architecture

The MMS Centre (MMS-C) is comprised of the MMS Server, the MMS Proxy-Relay and the MMS Store. The MMS Centre is the central element of the MMS network architecture, providing storage and operational support, enabling instant delivery of multimedia messages from terminal-toterminal and terminal-to-e-mail, and supporting flexible addressing. The centre’s MMS ProxyRelay interacts with the application being run on the MMS-enabled terminal to provide various messaging services. WAP is used as 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.

T300/T302

White Paper, August 2002

Figure 3. The architecture of MMS

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.

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.

T300/T302

White Paper, August 2002

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, downloading them from the Internet or editing them directly on the phone.

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 — more than just words

Sounds and melodies

EMS gives the user the ability to send and receive sounds. These can be pre-defined sounds, such as “Chime high” and “Notify ”, or melodies (ring signals in the phone), downloaded from the Internet, received in SMS messages or composed by the user on the phone keypad or a PC.

Several sounds and melodies can be inserted in one message, and they can be combined with pictures.

Pictures, animations and formatted text

Phones supporting EMS include a set of predefined pictures for inserting in SMS messages. New pictures and animations are downloaded from the Internet or received in SMS messages. Several pictures can be inserted in one message, and they can be combined with sounds and melodies. The users can format text in messages with different styles and sizes.

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.

New possibilities with messaging

The EMS standard is now a part of the SMS standard and supported by the major network operators and mobile phone manufacturers. This universal approach enables a fast penetration and development of new services and applications within messaging.

Creativity explosion

Users will be inspired to create and swap their own melodies and pictures. But more importantly, professional content creators and providers are already preparing to offer imaginative and creative contents for use with EMS. Based on subscriptions, fees or ads, network operators will be able to provide wide ranges of ring signals, operator logos and corporate icons, as well as personal and mood-related pictures and melodies. Movie, music and game companies can promote new products and events with designer melodies, animations and pictures.

Huge business potential

Network operators can now enhance their services and attract more customers by offering pictures, animations, ring signals and melodies for download at their portals. Operators can charge more per EMS message since it contains more data. Thereby EMS adds more value to the operators and to the end users.

Increase SMS revenue

EMS uses the same basic network support as ordinary SMS, and with the same familiar user interface. From an operator's point of view, SMS is low tech because minimal investment is needed to provide an effective SMS service to subscribers and little maintenance is required. EMS will create additional revenue for service providers and network operators by increasing SMS traffic.

T300/T302

White Paper, August 2002

Compatible with SMS standards

Users will find EMS as easy to use as SMS. At the moment 15 billion SMS messages, are sent every month worldwide. Roughly 80% of this traffic is user-to-user, i.e. mobile phone users sending short messages to each other using the keypad of the phone to enter text. The remaining 20 % is shared by downloads and notifications of different kinds.

The Enhanced Messaging Service (EMS) was first submitted to the standards committees by Ericsson. Ericsson presented the outline structure of EMS to the relevant ETSI/ 3GPP committees. The major mobile phone manufacturers and most operators are actively contributing to the 3GPP standards. Hence the EMS standards have evolved and are now stable and complete as part of the 3rd Generation Partnership Project (3GPP) technical specification.

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 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

Messages usually originating from the keypad of a mobile phone can include pictures, melodies, formatted text with EMS.

Voice and e-mail notifications

Notifying mobile phone users that they have new voice or fax mail messages waiting - including icons or melodies with EMS.

Unified messaging

The user typically receives a short message notifying them that they have a new message in their unified messaging box, with icons or formatted text further enhancing the message.

Internet e-mail alerts

An Internet e-mail alert is provided in the form of a short message that typically details the sender of the email, the subject field and first few words of the email message, and in this case formatted text is excellent to identify mesage elements.

Ring signals

Downloading ring signals from the Internet.

News & commercials

World news illustrated, sports scores and news headlines, finance and stock market news with diagrams and tickers, commercial product promotions, weather reports with maps, tunes from TV commercials as ring signals.

Info & entertainment

Ring signals, e-greetings, football club logo, joke-of-the-day illustrated by pictures or sound, horoscopes, movie related animation or theme song, TV show promotions, music artist promotions, lottery results, food and drinks pictures and recepies, mood-related pictures.

Corporate

Flight schedules, preinstalled corporate logos, map snippets and travel info, company branded icons and ring signals, corporate e-mail notifications, affinity programmes where companies notify customers of product updates etc, banks notifying customers about new services and interest rates, call centres providing answers to questions about a product, vehicle positioning combining EMS with Global Positioning System (GPS) position information, job dispatch with delivery addresses for sales or courier package delivery, using EMS in a retail environment for credit card authorization, remote monitoring of machines for service and maintenance purposes.

T300/T302

White Paper, August 2002

Using Web, WAP And SMS for download

Already today services exist on the Internet where users can create melodies, and view icons and pictures, subscribe to entertainment and informations services. These may develop further

in the future to support access via PC over the Internet, from the phone using WAP and even with an SMS request interface.

The diagram shows a model over the possibilities with Enhanced Messaging Service:

- When the Operator/Service provider enables EMS in the network, users will enjoy adding life to messages with sounds, melodies, pictures and formatted text.

- New ranges of Content/Application aggregators on the operator network or the Internet can provide EMS contents and services to the users over SMS.

- Content Creators/providers can see a new demand for creative contents. Also, promotional activities from movie companies, record labels etc can provide ring signals, movie snapshots etc.

The added value in SMS messaging will create new revenue which can be shared between the network operators, the application aggregators and the content providers.

T300/T302

White Paper, August 2002

WAP services

The T300/T302 has a WAP browser, supporting WAP 2.0 (WML 1.3). WAP 2.0 optimizes usage of higher bandwidths and packet-based connections of wireless networks.

The typical WAP client is a small, portable device connected to a wireless network. This includes mobile phones, pagers, smart phones, PDAs and other small devices. Of course, compared to desktop and laptop computers, these devices are limited by user interface, low memory and low computing power.

The WAP browser in the T300/T302 is compliant with WAP 2.0 and includes WTLS class 3 as well as mechanisms for digital signatures. It supports WML and XHTML. The WAP browser in the T300/T302 is also designed to access information such as timetables, share prices, exchange rates, Internet banking and other interactive services. For more details, see “WAP browser technical data” on page 55.

Using WAP in the T300/T302

The built-in WAP browser in the T300/T302 gives the user portable, fast and secure access to a wide variety of services, including personalized services, with new opportunities for business, individuals and service providers:

Support for cookies

This version of WAP has support for cookies (client based), an application used by Web sites to store site-specific information in the browser between visits to the site. Cookies give the site owner a possibility to see when a person has visited their site. They also save the user from having to enter the same information (e.g. the password or user ID) more than once. Cookies are often used by e-commerce sites (shopping carts and wish lists).

Sending bookmarks

WAP 2.0 enables the sending of bookmarks via infrared as well as via SMS.

Provide settings

Using SMS messages, configuration settings can be sent over the air, OTA, so that the user does not need to configure the WAP access settings manually. WAP settings may also be customized by the operator. For more information, see “WAP operator technical data” on page 56.

Adapt to phone type

The User Agent Profile function allows WAP content to be automatically optimized for the T300/T302, ensuring the intended user experience.

Several bearer types

The T300/T302 accesses WAP over a standard GSM Data connection as well as over a GPRS connection (network-dependent services.)

Push services

Businesses and service providers can “push” content or service indications to work groups and/or customers. Examples of pushed content would be mail alerts, messaging, news, stock quotes, contacts, meeting requests, etc.

Support of XHTML

Bandwidth efficiency

Unlike traditional Internet services, WAP services are relayed to wireless devices as binary encoded data, maximizing bandwidth efficiency. A GPRS connection further increases efficiency.

Easy create for WAP

Creating a WAP service is no harder than creating an Internet/intranet service, as WML and WMLScript are based on well-known Internet languages such as HTML and JavaScript.

Using standard tools

Service creators can use standard tools such as ASP (Active Server Page) or CGI (Common Gateway Interface) to generate content dynamically. Services can be created once and then made accessible on a broad range of wireless networks.

T300/T302

White Paper, August 2002

Maintain customer base

Existing services can be adapted to WAP. The necessary binary encoding is handled by a WAP Gateway, allowing HTML-based services to be viewed on the WAP browser of the T300/T302. An XHTML page can be viewed in both the WAP browser and in any standard Web browser.

Improve productivity

A business can use a WAP gateway to provide a secure connection to its corporate network, improving internal communication flow by making information available to mobile as well as office users.

The WAP profiles

A WAP profile holds network settings and user identification, allowing the user to switch easily between corporate services and WAP services on the Internet, simply by switching WAP profile.

The T300/T302 has dynamic WAP profile handling, which means that the user can add, edit and delete WAP profiles. The T300/T302 has a maximum of 5 WAP profiles.

During WAP browsing, the options button on the T300/T302 gives the user immediate access to a dynamic option menu for WAP services, similar to a mouse right-click in PC programs.

Bearer type characteristics

The T300/T302 accesses WAP services over IP. IP can be provided either over GSM Data or GPRS, depending on network services.

Typical differences which distinguish the bearer types are listed below.

GPRS access

• The connection is maintained “constantly”, with data transmitted in packets, and transmission capacity being used by the application in use on an as-needed basis.

• Higher transmission speed than with GSM Data or SMS access.

• Pricing of GPRS can be dependent on the actual use of bandwidth, which means the user is charged for the volume of data transmitted, rather than the duration of the connection.

• When transmitting large amounts of data, bandwidth can be increased automatically to allow faster transmission speed.

• Ideal for complex pull services, browsing, data transfer, provisioning, pager services, messaging services, info services, push initiations.

GSM data access

• Circuit connection of data calls, which means that the phone is connected during the entire WAP session.

• Pricing is comparable to that of data calls in the network.

Gateway characteristics

A WAP Gateway provides Internet/intranet as well as WAP services to the mobile browser. A Gateway is identified by an IP number, depending on access type.

End-to-end gateway navigation

The WAP 2.0 supports E2E (End-toEnd) Gateway navigation, making it possible for example for a bank to redirect its clients from the Internet gateway to its own gateway.

Security using WAP

For certain WAP services, such as banking services, a secure connection between the phone and WAP gateway is necessary. An icon in the display of the T300/T302 indicates when a secure connection is in use.

The T300/T302 is based on the WAP 2.0 (WML

1.3) specification suite, in which security

functionality is specified by a technology called Wireless Transport Layer Security (WTLS). The WAP protocols for handling connection, transport and security are structured in layers, with security handled by the WTLS layer, operating above the transport protocol layer. WTLS classes define the levels of security for a WTLS connection:

• WTLS class 1 — encryption with no authentication.

• WTLS class 2 — encryption with server authentication.

• WTLS class 3 — encryption with both server and client authentication.

T300/T302

White Paper, August 2002

Server authentication requires a server certificate stored at the server side and a trusted 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 is then referred to as a SWIM card.

Certificates

To use secure connections, the user needs to have certificates stored in the phone. There are two types of certificates:

• Trusted certificate A certificate that guarantees that a WAP site is genuine. If the phone has a stored certificate of a certain type, it means that the user can trust all WAP gateways that use the certificate. Trusted certificates can be pre-installed in the phone, in the SWIM or they can be downloaded from the trusted supplier’s WAP page.

• Client 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. Client certificates can be preinstalled in the SWIM card.

WIM locks (PIN codes)

There are two types of WAP security locks (PIN codes) for a SWIM, which protect the subscription from unauthorized use. The PIN codes should typically be provided by 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, much like a digital signature.

In the T300/T302, the user can check which transactions have been made with the phone when browsing. Each time the user confirms a transaction with a signature lock code, a contract is stored in the phone. The contract contains details about the transaction.

Configuration of WAP settings

An easy way to perform WAP configuration in the T300/T302 is to use the step-by-step WAP configurator available on http:// www.SonyEricsson.com. The configurator utilizes OTA provisioning.

Manual configuration is done using the menu system in the phone. This is described in the User’s guide.

Over-the-air provisioning of WAP settings

To simplify the configuration of WAP settings in the T300/T302, all settings can be sent to the phone as an SMS message. This makes it easy for an operator, a service provider or a company to distribute settings for Internet/intranet, and WAP, without the user having to configure the phone manually. This also makes it easy to upgrade services, as no manual configuration is required.

• The OTA configuration message is distributed via SMS point-to-point.

• The setup information is a binary encoded XML message (WBXML). To receive information about OTA specifications, please contact your local Sony Ericsson representative for consumer products. A configurator that utilizes OTA provisioning can be tested on www.SonyEricsson.com.

• The user is alerted about new settings when the ongoing browsing session ends. Settings are not changed during an ongoing browsing session.

• User interaction is limited to receiving and accepting/rejecting the configuration message, and selecting which WAP profile to allocate the settings to.

• Security can be handled using a keyword identifier displayed on the screen as a shared secret between the SMS sender and recipient. It is important that the user can verify that the configuration message is authentic.

T300/T302

White Paper, August 2002

Push services

Examples of WAP services that can be pushed include:

• Notification of new e-mail, voice mail, etc.

• News, sports results, weather forecasts, financial information (stock quotes etc.).

• Personal Information Manager (PIM) delivery of contacts, meeting requests etc.

• Smart card e-cash.

• Interactive games.

In the T300/T302, the user selects whether to allow push messages or not. There are two different forms of Push services:

Service Indication (SI)

An SI service sends to the browser a text message with a URL of a WAP page. If the user decides to load the URL, normal WAP browsing commences. When an SI is received by the T300/ T302, the user can load it immediately, postpone it or delete it. Received SIs are stored in the Push Inbox and can be viewed and loaded at a later time. The Push Inbox displays a list containing the first part of each received message. The list is sorted by action attribute (high/medium/low) or reception time of the message.

Service Loading (SL)

An SL service sends and displays a WAP page if accepted by the user. If the SL is not accepted, it is loaded and stored in the cache for later use. The user can start the browser and load the page from the cache manually.

Mobile Internet

The mobile Internet offers much more than mobile access to the Internet. It opens up a whole new range of situation-based services that give the user access to personalized communications, information and entertainment, anytime, anywhere.

Data connections

In order to browse via WAP or use an Internet connection, the user must have a data communication connection configured in the phone. This connection contains specific settings and parameters to connect to an appropriate server. Several data connections can be saved in the T300/T302. To make it easier for the user, data connections can be provided by the operator via OTA provisioning.

Advantages of data connections include:

• Once the data connections are defined and named, the user does not have to enter the settings for the connection again.

• Data connections can be re-used at any time.

• Individual data settings for working with WAP, e-mail or the Internet can be stored and activated as needed.

• Data connections can be used for both GSM Data and GPRS connection settings.

• Bearer type for WAP and corresponding bearer-specific parameters may be selected.

• Data connections contain all the necessary settings for the Internet access point, including modem pool phone number or IP address, user ID and password.

Mobile positioning

The geographic location of mobile subscribers can be used to provide them with related information and a variety of services. Sony Ericsson’s Mobile Positioning System (MPS) gives operators a fast and cost-effective way to establish and roll out location-based services.

More information regarding possibilities with and technologies for mobile positioning is available at http://www.SonyEricsson.com/mps

General Packet Radio Services

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, ecommerce 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.

With GPRS, the T300/T302 sends data in “packets” at a very high speed. The T300/T302 remains connected to the network at all times, using transmission capacity only when data are sent or received. For details, see “GPRS technical data” on page 60.

1. A normal GSM call uses only one of eight

repeating time slots in the GSM channel, giving a data speed of 9,600 bps. The T300/T302 supports a more efficient coding scheme, giving data speeds of up to 14,400 bps (with necessary network support). Furthermore, High Speed Circuit Switched Data (HSCSD) adds the possibility of using two time slots for receiving data, increasing the data speed to as much as 28,800 bps (net-

Using GPRS in the T300/T302

Instead of occupying an entire voice channel for the duration of a data session, the T300/T302 sends/receives data in small packets, as needed, much like IP on the Internet. Because of this, the T300/T302 maintains a constant online connection, its data transmission abilities summoned by the application in use on an asneeded basis.

The GPRS specification includes four coding schemes — CS1, CS2, CS3 and CS4 — that allow data speeds of 9,050 bps, 13,400 bps, 15,600 bps and 21,400 bps respectively. The T300/T302 works with all four coding schemes, but data speed will naturally vary according to network configuration. At the moment, CS-3 and CS-4 are not supported in any live network, i e present

work dependent).

2. In GPRS, data is sent in packets, with up to

three time slots being combined to provide the necessary bandwidth. The T300/T302 is prepared to support 3+1 time slots, giving speeds of up to 64,200 bps for receiving data, depending on coding scheme.

speed is limited to 40,200 bps.

The GSM system limits the ability to use all eight time slots, so the T300/T302 uses up to three time slots for receiving data, and one slot for transmitting. This means the speed for receiving data is up to 64,200 bps and up to 21,400 bps for sending data.

Information about the identity of the phone and the characteristics 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.
