Product overview

White Paper T310/T312

The Sony Ericsson T310/T312 is designed for entertainment and imaging, with features that are bursting with fun for consumers, and its a revenue winner for network operators. The T310/T312 marketing focus is on mobile gaming, imaging and messaging. It has all EMS and picture messaging (text messaging with pictures and sounds), e-mail and MMS (Multimedia messaging), and a snap-on camera as a core accessory.

Key functions and features

Downloadable games

Gaming is already a very popular feature in Sony Ericsson phones. Now the mobile Internet portal offers the possibility of downloading games. Network 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.

With a GPRS (General Packet Radio Services) modem built in, the T310/T312 offers a fast and satisfying mobile Internet experience. The T310/ T312 is a triple band 900/1800/1900 premium product which is planned to be available Q1, 2003.

menu. The flexibility of the downloadable games solution is dedicated to provide an enhanced gaming experience.

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.

T310/T312 games download is made possible by a true virtual machine. The Sony Ericsson portal for downloading of games for the T310/T312 is accessible with only one key press in the games

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 technology for the highest level of security.

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

Polyphonic ring signals

Pleasing to the ear, polyphonic ring signals can play up to 32 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 ring signals.

T310/T312 users can share ring signals, and download them from the Web.

5 January 2003

Page 6

White Paper T310/T312

Early Ericsson mobile phones supported a proprietary 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 non-polyphonic 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 text information as binary data about what, when and how an instrument/melody is played. When this data reaches a synthesizer, the synthesizer translates it into music from the following attributes:

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.

Digital Rights Managements

Digital Rights Management (DRM) is a technology that enables secure distribution, promotion and sale of Digital Media.

T310 includes implementation of EMS ODI (Object distribution Indicator) and MMS limited forwarding (Sony Ericsson proprietary forward lock for MMS content).

When downloading via WAP, the T310 includes support for OMA (Open Mobile Alliance) defined DRM solution forward lock, meaning that Content is packaged in a DRM package and delivered to the device. The support of forward lock means that it is not possible to forward the downloaded content to any other device. Forward lock is useful for all types of content that the provider wants to charge for.

• What instrument is to be selected and played by the synthesizer.

• How a melody is played.

• When connected to an amplifier with speakers,

the sound becomes audible.

Please visit www.midi.org for more information.

Imaging

With a digital camera attached to your T310/T312, you can take, view, store and send high-quality 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 on-line 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.

Related information such as the “OMA-Download- DRM, v1.0” specification can be found at http:// www.openmobilealliance.org/documents.html.

Multimedia Messaging

Reacting to the enormous popularity of mobile phone messaging, Sony Ericsson has incorporated the latest messaging standard into the T310/T312, along with a colour display for an enhanced imaging experience.

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 T310/T312. 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.

Full graphic 256 colour display

The large colour display of the T310/T312 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 on the keypad

The T310/T312 has an easy-to-use 5-directional joystick function. Using finger or thumb, you can easily navigate the new T310/T312 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 T310/ T312 MMI is adapted for easy joystick navigation.

Browser supporting WAP 2.0 - XHTML™

The T310/T312 supports the WAP 1.2.1 browser and protocol stack as well as the WAP 2.0 browser.

The 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.

GPRS

GPRS uses Internet-style packet based technology. It uses the radio link only for the duration of time that it transfers data. GPRS offers the user the speed needed for satisfactory mobile Internet usability. The T310/T312 supports GPRS 3+1.

Design

The basic form gives a strong and sophisticated product image by using a simple cylindrical shape with relaxed, smooth surfaces and slightly curved sides featuring concave grips. The bezel surrounding the display wraps across the front surface creating an innovative wide-screen design element. The split-line speaker outlet between the front and the bezel enables a completely new look reducing unnecessary ornamental detailing. The navigation keys are clustered into one design detail around the joystick to ensure best possible ergonomics. Below the keypad is a small expansion of the surface, featuring a separate detail, which enhances the grip while pushing the lower keys. The front cover is not exchangable and the battery cover slides into place. There is also a loophole for a carrying strap accessory.

Customization

The T310 has a separate co-brand inlay part for more flexible customization. The co-brand inlay is snapped on to the front, in the area below the keypad, and is mounted on the phone as the last step in our production chain. This makes it possible for a shorter lead time when printing operator details on customized phones. Furthermore, the co-brand print is covered with a top coat for greater wear resistance.

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

T310/T312 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.

Content

Content such as games, pictures and sounds can vary depending on the customization requirements.

This document describes the general content plan for T310. Content can also be found at http://wap.SonyEricsson.com.

Direct download links

The direct download link is a function designed to encourage downloading of content via WAP to enrich the user experience. Furthermore the

download link also tries to influence the user to use WAP-based services and get used to using data oriented services on the network.

The Fun&Games menu includes a link called Download which directs the user to the Sony Ericsson WAP site where there are links to Games, Pictures, Themes and Sounds.

More in-phone functions

E-mail

The T310/T312 has a fully functional e-mail client. With inbox, outbox, save draft and reply options, you have all the functions you need for effective email communication in a small and powerful mobile phone. Constantly connected to a POP3, SMTP or IMAP4 e-mail server anywhere on the Internet, your T310/T312 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 e-mail 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 easy-tocreate and fun messages. EMS has been adopted by several leading mobile phone manufacturers, making it possible for T310/T312 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 pre-defined images and animations in the T310/T312.

Predictive Text Input Software

Text messaging with your T310/T312 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 T310/ T312 chooses from a dictionary of words and phrases and anticipates what word or phrase you

The presence of the link and the URL of the link can be customized according to customer choice. It is also possible for operators to include an additional link with their own URL and generic name for all languages.

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 pre-defined 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

Most applications in the T310/T312 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 downloaded content from applications, in order to set memory free. The memory available for the user is approximately 340 KB (Kilobytes).

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.

White Paper T310/T312

Picture phone book

The phone book in the T310/T312 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 T310/T312 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 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 5

Camera application

The camera application in the T310/T312 supports the Communicam™ MCA-20 and 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.

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 pre-defined themes. It is possible to download and exchange additional themes. The maximum number of themes is limited only by the amount of free memory.

Multimedia in the T310/T312

The T310/T312 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 T310/ T312 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.

Audio

The user of the T310/T312 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 T310/ T312 also allows downloading of sounds and melodies.

Pictures

With a digital camera attached to your T310/T312, you can take, view and store pictures. It is also possible to download colour pictures to your T310/ T312. 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 T310/T312 can be used for creating your own digital postcards. This is easily done by adding text to the pictures and sending them via MMS.

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 pre-defined 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 71 and “Images – downloading to phone” on page 71.

MMS (Multimedia Messaging Service)

One of the key features in the T310/T312 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 T310/T312 can contain text, graphics, animations, images, audio clips and ring melodies. For more detailed information, see “Multimedia Messaging Service” on page 55. For third-part developers’ information, please visit www.SonyEricsson.com/mobilityworld/ and look for the MMS Developers’ guidelines.

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.

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 high-speed 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

MMS objects

White Paper T310/T312

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.

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 l at e s

The T310/T312 comes with a number of MMS predefined templates, for example templates for birthday cards, meeting requests etc.

Audio

MMS provides the ability to send and receive full sound (iMelody, MIDI and AMR) 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”.

Mobile picture transmission also offers inestimable utility in business applications, from sending onsite 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 T310/T312 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

PIM communication with MMS

With MMS in the T310/T312, it is easy to send and receive business cards (vCard) and events.

Pictures and themes

By using either a digital camera attached to the T310/T312 with 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.

Benefits

White Paper T310/T312

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 inter operability,

MMS technical features

The MMS standard, just like SMS, offers store-andforward 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.

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 inter operability 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.

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-to-terminal and terminal-to-e-mail, and supporting flexible addressing. The centre’s MMS Proxy-Relay

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.

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.

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

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

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.

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.

14 January 2003

Page 15

White Paper T310/T312

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 EMS service to subscribers and little maintenance is required. EMS will create additional revenue for service providers and network operators by increasing SMS traffic.

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.

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 e-mail, the subject field and first few words of the e-mail message, and in this case formatted text is excellent to identify message elements.

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.

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, jokeof-the-day illustrated by pictures or sound, horoscopes, movie related animation or theme

15 January 2003

White Paper T310/T312

song, TV show promotions, music artist promotions, lottery results, food and drinks pictures and recipes, mood-related pictures.

Corporate

Flight schedules, pre installed 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.

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.

WAP services

White Paper T310/T312

The T310/T312 supports the WAP 1.2.1 browser and protocol stack as well as the WAP 2.0 browser.

The T310/T312 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

Using WAP in the T310/T312

The built-in WAP browser in the T310/T312 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:

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

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.

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

desktop and laptop computers, these devices are limited by user interface, low memory and low computing power.

The WAP browser in the T310/T312 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 T310/T312 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 59.

the same information (e.g. the password or user ID) more than once. Cookies are often used by ecommerce 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 61.

Adapt to phone type

The User Agent Profile function allows WAP content to be automatically optimized for the T310/ T312, ensuring the intended user experience.

Several bearer types

The T310/T312 accesses WAP over a standard GSM Data connection as well as over a GPRS connection (network-dependent services.)

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.

17 January 2003

Page 18

White Paper T310/T312

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.

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 T310/T312. 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 T310/T312 has dynamic WAP profile handling, which means that the user can add, edit and delete WAP profiles. The T310/T312 has a maximum of 5 WAP profiles.

During WAP browsing, the options button on the T310/T312 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 T310/T312 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

• Data is transmitted in packets, with transmission capacity being used by the application in use on an as-needed basis.

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

Gateway characteristics

• Pricing of GPRS can for example be dependent on the volume of data transmitted, rather than the duration of the connection.

• 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.

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

White Paper T310/T312

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 T310/T312 indicates when a secure connection is in use.

The T310/T312 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.

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.

Certificates

To use authenticated 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 pre-installed 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.

A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys and algorithms needed for WTLS handshaking and signature generation. The WIM module can be placed on a SIM card and is then referred to as a SWIM card.

• Signature lock

In the T310/T312, 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 T310/T312 is to use the step-by-step WAP configurator available on http:// www.SonyEricsson.com. The configurator utilizes

OTA provisioning.

19 January 2003

A signature lock is used for confirming transactions, much like a digital signature.

Page 20

White Paper T310/T312

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 T310/T312, 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.

Push services

Examples of WAP services that can be pushed include:

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

• News, sports results, weather forecasts, finan-

cial information (stock quotes etc.).

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

• Smart card e-cash.

• Interactive games.

In the T310/T312, 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 T310/T312, 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.

20 January 2003

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

White Paper T310/T312

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 T310/T312. 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 bearerspecific 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.

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

21 January 2003

Page 22

White Paper T310/T312

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

9,600/14,400

9,050/13,400/ 15,600/21,400

scale and can reap the associated benefits. GPRS also provides a secure way to connect to private networks, banking and financial services.

With GPRS, the T310/T312 sends data in “packets” at a very high speed. The T310/T312 uses transmission capacity only when data is sent or received. For details, see “GPRS technical data” on page 66.

9,050/13,400/ 15,600/21,400

A comparison between GSM and GPRS

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 T310/T312 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 (network dependent).

2. In GPRS, data is sent in packets, with up to three time slots being combined to provide the necessary bandwidth. The T310/T312 is prepared to support 3+1 time slots, giving speeds of up to 40,200 bps for receiving data, depending on coding scheme.

22 January 2003

Page 23

Using GPRS in the T310/T312

White Paper T310/T312

Instead of occupying an entire voice channel for the duration of a data session, the T310/T312 sends/receives data in small packets, as needed, much like IP on the Internet. Because of this, the T310/T312 has 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 theoretical data speeds of 9,050 bps, 13,400 bps, 15,600 bps and 21,400 bps respectively. The T310/ T312 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 speed is limited to 40,200 bps.

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.

Using GPRS with the T310/T312 has several advantages, for example:

• All connection settings can be managed by using the data connections feature.

• High speed

• Cost efficient when downloading large files,

images etc.

• Use transmission capacity only when needed, thus reducing costs.

• WAP over GPRS

• Access the Internet via WAP at high speed.

• E-mail over GPRS

• Data communication

• Transfer data and access the Internet or an

intranet with a PC, PDA or handheld device connected via infrared.

• Receive GPRS configuration settings from the provider over the air, OTA, making manual configuration unnecessary.

• User controlled settings

• Take advantage of full user control in the data

connections menu, establishing multiple descriptions and accessing advanced settings for GPRS.

Modem and AT commands

The T310/T312 contains a complete GSM/GPRS modem. This provides data and e-mail communication, as well as Internet/intranet access, for a connected PC, PDA or handheld device. Once the PC/PDA is connected to the phone using infrared, and the appropriate software is installed, the modem in the phone works in a similar way to a PC Card modem, or an external modem.

GSM data communication

The built-in data capability turns the phone into a modem when connected to a PC/PDA. The T310/ T312 offers the user data connection anytime, anywhere, unmatched by fixed telephone networks. Each GSM channel is divided into eight

In the T310/T312, AT commands are used for:

• controlling the data communication between the PC and the remote service

• configuring and requesting settings and behaviours in the phone, from a connected PC or PDA

repeating time slots. A normal GSM voice or data call is circuit switched, and only one time slot is used for each call. The data speed is therefore

23 January 2003

Page 24

White Paper T310/T312

limited to 9,600 bps. For more information, see “Built-in GSM data modem technical data” on page 69.

High Speed Data gives a faster speed

High Speed Data (HSCSD) increases speeds for circuit switched data by allowing the phone to use a coding scheme with a high capacity, and to use two time slots for receiving data. The download speed is increased to up to 28,800 bps. The speed for sending data is limited to 14,400 bps. The data rate can be increased several times by the use of

AT commands support

This section outlines the AT commands supported by the T310/T312. The information here can be of use for advanced users, to indicate the possibilities they have to:

rate adaption, inter working with ISDN. This also provides additional features, such as quick call setup capability.

GPRS at high speed

With GPRS data is transmitted in packets. Pricing of GPRS may be dependent on the data transmitted, which means very low cost when no data is sent or received. When transmitting large amounts of data, it may be possible to increase bandwidth automatically to allow faster transmission speed, up to 40,200 bps download speed.

On-line data mode

Allows “normal” operation of the built-in modem, for exchanging data or facsimiles with a remote modem.

• develop new communications software

• add the T310/T312 to an application’s list of

compatible modems

• adjust the settings of their mobile telephone and modem

The modem in the T310/T312 supports the V.25ter command set, which is the standard communication set used by modems.

The T310/T312 is compatible with industry de facto extensions, ETSI 07.05, 07.07 and 07.10.

Overview of AT command functions

AT commands are used to configure the mobile telephone, to request information about the current configuration or operational status of the mobile phone, and to test availability and request the range of valid parameters, when applicable, for an AT command.

The built-in modem can be set to any one of three modes of operation. These are:

Off-line command mode

The command mode for entry of AT commands, when the device is first turned on.

On-line command mode

For sending AT commands to the built-in modem while remaining connected to a remote modem.

The AT commands in the T310/T312 are grouped as follows:

• Control and Identification

• Call Control

• Interface Commands

• Data Compression

• Mode Management

• Audio Control

• Accessory Menus

• Accessory Authentication

• Voice Call Control

Infrared transceiver

Infrared communication creates a data link between two communications devices through an infrared beam of light. On the T310/T312, this link is used to connect with desktop computers, PDAs, Sony Ericsson handheld computers, laptop PCs, other phones (for example, the T68i), and other hardware supporting the standard. The Infrared Data Association (IrDA) has set the hardware and software standards that form the infrared communication links. The T310/T312 complies with the IrMC 1.1 specification, which defines how mobile telephony and communication devices can exchange information. Key benefits of using the T310/T312 with its built-in infrared transceiver:

• ObEx

• WAP Browser

• True wireless communication

• Low power consumption

• Ability to send and receive e-mail and data on

the connected PC/PDA

• Ability to connect to the Internet or intranet/LAN from the connected PC/PDA

• Ability to manage the phone book from a PC

• Exchange of business cards with vCard

compatible devices

• Exchange of ring signals between compatible phones

• Ability to attach a photo from a digital camera in outgoing e-mail

Connection via infrared

IrDA is a point-to-point communication link between two infrared ports. The infrared beam has to be directed towards the target infrared port and as long as the two infrared ports are within sight and range, the devices exchange data. For optimal performance, place the T310/T312 within 20/30 cm and in direct line with the infrared port on the PC/ PDA, or other phone. An advantage of the necessary proximity of devices is reduced risk of transmitting data to other nearby devices. An infrared link is a serial connection, which means that data bits are sent one after another in a long stream. The IrDA–SIR Data Link Standard is a protocol that makes transmission of data faultless. The standard provides a high level of noise immunity, which means that the connection should not be affected by standard fluorescent light and electromagnetic fields – making it suitable for the modern office environment. However strong sunlight may affect the connection.

SIM application toolkit

The SIM Application Toolkit (SIM AT) is a smart card-centric method of deploying programs that apply only to GSM and to SMS and USSD transports. Programs must be distributed on smart cards. WAP is an Internet-centric method of deploying programs that is independent of network technology. Programs and content are kept centrally on web servers and downloaded as required. While there is some overlap, WAP is a particularly good choice when deploying programs that also have an HTML version for desktop use. Work is currently under way on building interfaces between the two technologies.

For an operator, a company or service provider, SIM AT offers a powerful way to deploy programs and services to users, without the need for new or upgraded equipment. All necessary setup and programming is distributed to users over the air, directly to their phones. In the T310/T312, a separate menu is available for functions residing on the SIM card. These can include sub menus for controlling functions, and also functions which allow the phone to initiate calls, send data, and display information to the user.
