T300/T302  
White Paper, August 2002  
T300/T302 users can share ring signals, and  
download them from the Web.  
Product overview  
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  
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), e-  
mail and MMS (Multimedia messaging), and a  
snap-on camera as a core accessory.  
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.  
With a GPRS (General Packet Radio Services)  
modem built in, the T300/T302 offers a fast and  
satisfying mobile Internet experience. The T300/  
T302 is a triple band 900/1800/1900 premium  
product which is planned to be available Q4,  
2002.  
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.  
Key functions and features  
Multimedia Messaging - Digital  
greetings  
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.  
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.  
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.  
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.  
With MMS, the subscription applications get  
more interesting, for example stock information,  
movie trailers and weather reports.  
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.  
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.

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.  
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.  
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.  
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.  
The software development kits are available via  
Imaging  
With a digital camera attached to your T300/  
T302, 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 online image  
Joystick navigation  
collections already exist on the Web and many  
sites are already gearing up to include images for  
use in mobile phones.  
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.  
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.  
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.  
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.  
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.

White Paper, August 2002  
Memory management  
More in-phone functions  
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.  
E-mail  
The T300/T302 is one of the first mobile phones  
on the market with a built-in fully functional e-  
mail 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)  
Mobile chat  
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  
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.  
outgoing e-mails, but not receive attachments.  
Hyperlinks in e-mails are supported.  
Picture phone book  
EMS (Enhanced Messaging Service)  
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.  
You can send text, pictures and sounds in easy-  
to-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 pre-  
defined images and animations in the T300/  
T302.  
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.  
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.  
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.  
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.

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. 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.  
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.

Themes  
Multimedia in the  
T300/T302  
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.  
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.  
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.  
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.  
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.

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.  
For third-part developers’ information, please visit  
for the MMS Developers’ guidelines.  
Figure 1. An MMS message can contain images,  
music, 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.  
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 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.  
An MMS message can contain one or more of the  
following:  
Text  
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.  
Templates  
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  
PIM communication with MMS  
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”.  
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.  
.
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.  
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.  
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  
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.  
Because MMS uses WAP as its bearer  
technology and is being standardized by 3GPP, it  
has wide industry support and offers full  
interoperability, which is a major benefit to  
service providers and end users. Ease-of-use  
resulting from both the gradual steps of the  
messaging evolution and the continuity of user  
experience gained from interoperability is  
assured.  
The 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  
10  
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 store-  
and-forward transmission (instant delivery) of  
messages, rather than a mailbox-type model.  
MMS is a person-to-person communications  
solution, meaning that the user gets the message  
directly into the mobile. He or she doesn’t have to  
call the server to get the message downloaded to  
the mobile. 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-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.  
11  
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.  
12  
T300/T302  
White Paper, August 2002  
Concatenated messages  
EMS (Enhanced  
Messaging  
Service)  
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.  
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.  
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  
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.  
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  
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.  
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.  
Several sounds and melodies can be inserted in  
one message, and they can be combined with  
pictures.  
Pictures, animations and formatted  
text  
Increase SMS revenue  
Phones supporting EMS include a set of pre-  
defined 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.  
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  
Voice and e-mail notifications  
Compatible with SMS standards  
Notifying mobile phone users that they have new  
voice or fax mail messages waiting - including  
icons or melodies with EMS.  
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.  
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.  
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  
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.

specification.  
News & commercials  
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

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.

T300/T302  
White Paper, August 2002  
Using Web, WAP And SMS for download  
in the future to support access via PC over the  
Internet, from the phone using WAP and even  
with an SMS request interface.  
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  
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  
Support for cookies  
WAP services  
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).  
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.  
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.  
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.  
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.  
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:  
Several bearer types  
The T300/T302 accesses WAP over a standard  
GSM Data connection as well as over a GPRS  
connection (network-dependent services.)  
Bandwidth efficiency  
Push services  
Unlike traditional Internet services, WAP services  
are relayed to wireless devices as binary  
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.  
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.  
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,  
checkboxes, radio buttons, text areas, headings,  
horizontal rules and lists.  
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  
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 ini-  
tiations.  
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.  
GSM data access  
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.  
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.  
The WAP profiles  
Gateway characteristics  
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.  
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.  
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.  
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.  
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.  
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.  
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.  
The T300/T302 is based on the WAP 2.0 (WML  
1.3) specification suite, in which security  
Typical differences which distinguish the bearer  
types are listed below.  
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:  
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.  
WTLS class 1 — encryption with no authen-  
tication.  
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.  
WTLS class 2 — encryption with server  
authentication.  
WTLS class 3 — encryption with both server  
and client authentication.  
17  
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.  
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.  
Client authentication requires a client certificate  
stored at the client side and a trusted certificate  
stored at the server side.  
Configuration of WAP  
settings  
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.  
An easy way to perform WAP configuration in the  
T300/T302 is to use the step-by-step WAP  
configurator available on http://  
utilizes OTA provisioning.  
Certificates  
To use secure connections, the user needs to  
have certificates stored in the phone. There are  
two types of certificates:  
Manual configuration is done using the menu  
system in the phone. This is described in the  
User’s guide.  
Trusted certificate  
Over-the-air provisioning  
of WAP settings  
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.  
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.  
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 certifi-  
cate. Client certificates can be pre-  
installed in the SWIM card.  
The OTA configuration message is distrib-  
uted via SMS point-to-point.  
The setup information is a binary encoded  
XML message (WBXML). To receive infor-  
mation about OTA specifications, please  
contact your local Sony Ericsson repre-  
sentative for consumer products. A config-  
urator that utilizes OTA provisioning can be  
The user is alerted about new settings  
when the ongoing browsing session ends.  
Settings are not changed during an ongo-  
ing browsing session.  
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  
User interaction is limited to receiving and  
accepting/rejecting the configuration mes-  
sage, and selecting which WAP profile to  
allocate the settings to.  
A signature lock is used for confirming  
transactions, much like a digital signature.  
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  
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.  
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.  
Interactive games.  
Data connections  
In the T300/T302, the user selects whether to  
allow push messages or not. There are two  
different forms of Push services:  
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.  
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.  
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.  
Service Loading (SL)  
Individual data settings for working with  
WAP, e-mail or the Internet can be stored  
and activated as needed.  
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.  
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 General Packet  
Radio Services  
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.  
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  
More information regarding possibilities with and  
technologies for mobile positioning is available at  
portable device. That is why the main  
applications driving Mobile Internet development  
are e-mail clients and Web browsers.  
The demand for high-speed Internet access will  
be the key driver for coming generations of  
wireless services, and GPRS can deliver the  
necessary speed. GPRS allows innovative  
services to be created, enabling new and  
previously inaccessible market segments to be  
addressed and increasing customer loyalty.  
GPRS applications can be developed as both  
horizontal and vertical. Vertical applications are  
specific, including those for operations such as  
reaching police and emergency, taxi, delivery or  
automated services (vending machines,  
supervision, vehicle tracking). Horizontal  
applications are more generic and include those  
for Internet access, e-mail, messaging, e-  
commerce and entertainment.  
GPRS is able to take advantage of the global  
coverage of existing GSM networks.  
Applications developed for GPRS can be  
deployed on a large scale and can reap the  
associated benefits. GPRS also provides a  
secure medium for connections to private  
networks, banking and financial services.  
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 sup-  
ports a more efficient coding scheme, giving data  
speeds of up to 14,400 bps (with necessary net-  
work support). Furthermore, High Speed Circuit

pared 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.  
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 as-  
needed basis.  
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  
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  
described in the PDP (Packet Data Protocol)

phone and in the mobile network, so that each  
phone is identified and “visible” to the system.

T300/T302  
White Paper, August 2002  
GPRS enables constant connection  
and high speed  
Modem and AT  
commands  
With GPRS, the connection is maintained  
“constantly”, and data is transmitted in packets.  
Pricing of GPRS can be dependent on the actual  
use of bandwidth, which means very low cost  
when no data is sent or received, while the phone  
remains connected. When transmitting large  
amounts of data, bandwidth can be increased  
automatically to allow faster transmission speed,  
up to 64,200 bps download speed.  
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.  
AT commands support  
This section outlines the AT commands  
supported by the T300/T302. The information  
here can be of use for advanced users, to  
indicate the possibilities they have to:  
In the T300/T302, AT commands are used for:

networks. Each GSM channel is divided into eight  
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  
limited to 9,600 bps. For more information, see  
“Built-in GSM data modem technical data”  
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.  
on page 62.  
High Speed Data gives a faster speed  
The built-in modem can be set to any one of three  
modes of operation. These are:  
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 rate adaption,  
interworking with ISDN. This also provides  
additional features, such as quick call set-up  
capability.  
Off-line command mode  
The command mode for entry of AT commands,  
when the device is first turned on.  
On-line data mode  
Allows “normal” operation of the built-in modem,  
for exchanging data or facsimiles with a remote

T300/T302  
White Paper, August 2002  
Connection via infrared  
Infrared  
transceiver  
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 T300/T302 within  
a metre and at an angle of 30 degrees to 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 is not affected by  
fluorescent light, sunlight and electromagnetic  
fields — making it suitable for the modern office  
environment.  
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. The T300/T302  
complies with the IrMC 1.1 specification, which  
defines how mobile telephony and  
communication devices can exchange  
information. Key benefits of using the T300/T302  
with its built-in infrared transceiver:  
True wireless communication  
Low power consumption  
Secure data transmission with the IrDA  
DATA standard  
Ability to send and receive e-mail and data  
on the connected PC/PDA  
Ability to connect to the Internet or intra-  
net/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 compati-  
ble phones  
Ability to attach a photo from a digital cam-  
era in outgoing e-mail

Network-dependent  
features  
SMS and EMS messaging  
The T300/T302 is capable of sending and  
receiving SMS and EMS messages, and linked  
messages.  
With the Short Messaging Service, a user  
can send text messages containing up to  
160 characters to and from GSM mobile  
stations  
With the linked SMS, the user can link up  
to 10 SMS messages together to create a  
longer message (network-dependent ser-  
vice)  
A Service Centre (SC) acts as a a storage and  
forwarding centre. The T300/T302 also supports  
using SMS as a bearer type for connecting to  
WAP.  
SMS consists of two basic services:  
Mobile Originated SMS  
Mobile Terminated SMS  
For Mobile Originated SMS, an SMS message is  
sent from a Mobile Station to the SMS-C where it  
is forwarded to its destination. This can be  
another Mobile Station, or a terminal in the fixed  
network.  
A Mobile Terminated SMS is when an SMS  
message is forwarded from the SMS-C to a  
Mobile Station. When the Mobile Station receives  
the message, it returns a delivery report saying  
the transfer was successful.  
Fixed dialling and Restricted calls  
For a company or an organization, it can be  
useful to restrict phone calls. Fixed dialling  
allows the user to preset a number of digits, for  
example area codes. This restricts the user to  
making calls only to numbers which use the  
preset digits as leading digits. Fixed dialling  
makes use of the PIN2, and it requires fixed dial  
fields on the SIM card.  
The Restrict calls service allows the user to block  
outgoing or incoming calls in certain situations,  
for example international calls.

particularly good choice when deploying  
SIM application  
toolkit  
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 T300/T302, a  
separate menu is available for functions residing  
on the SIM card. These can include submenus for  
controlling functions, and also functions which  
allow the phone to initiate calls, send data, and  
display information to the user.  
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
