T300/T302 White Paper, August 2002 Preface Purpose of this document The Sony Ericsson T300/T302 White Paper is designed to give the reader a deeper technical understanding of how the T300/T302 is designed, and of how it interacts with other media. This document will make it easier to integrate the T300/T302 with the IT and communications solutions of a company or organization.
T300/T302 White Paper, August 2002 Product overview The T300/T302 is Sony Ericsson´s rough diamond - calm, plain and simple in appearance but absolutely bursting with fun features for consumers and revenue winners for network operators. The T300/T302 marketing focus is on messaging. It has all EMS and picture messaging (text messaging with pictures and sounds), email and MMS (Multimedia messaging), and a snap-on camera as a core accessory.
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.
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.
T300/T302 White Paper, August 2002 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.
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.
T300/T302 White Paper, August 2002 MMS (Multimedia 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
T300/T302 White Paper, August 2002 Push services Mobile Internet 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.
T300/T302 White Paper, August 2002 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.

WAP over GPRS Access the Internet via WAP at high speed and with a constant connection.
T300/T302 White Paper, August 2002 Modem and AT commands The T300/T302 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.

T300/T302 White Paper, August 2002 Infrared transceiver Infrared communication creates a data link between two communications devices through an infrared beam of light. On the T300/T302, this link is used to connect with desktop computers, PDAs, Sony Ericsson handheld computers, laptop PCs, other phones (for example, the T39), and other hardware supporting the standard. The Infrared Data Association (IrDA) has set the hardware and software standards that form the infrared communication links.
