White Paper T610/612
T610/12 overview
T610/612 is an innovative and easy to use high-end
mobile phone. It offers complete imaging and messaging
capabilities that allow both family and friends to capture,
share and preserve those special moments.
Designed with professional user in mind, T610/612’s
powerful efficiency makes it an ideal tool in the professional work place.
Featuring a large colour LCD display with 65536 colours, it offers the viewer sharp, detailed images in rich,
natural colours. The built-in camera makes taking a picture quick and easy and automatically shows the subject
in the display. Pictures can then be used as wallpapers, in
multimedia messages and in the phone book.

Features and functions
Built-in CommuniCam
White Paper T610/612
The built-in camera is capable of taking still pictures up
to common image format (CIF) resolution (352x 288
pixels) and 24 bit colour depth. The lens is recessed into
the back of the T610/612. The viewfinder will fill up the
whole screen, irrespective of the resolution at which the
picture is taken. A dedicated hardware button provides
fast access to the camera application.
Images are stored in the phone’s filing system and are
therefore available for other applications to use. The
number of images that can be stored depends on the
available file space, which is shared with other applications. The viewfinder will give an estimation of the
number of images remaining, assuming that all of the
free storage is available for the camera application and
using the current settings for size and quality. Approximate JPEG file sizes are 20 kbytes for CIF.
Pictures
Pictures is the T610/12’s image viewer. It enables you to
view and organise your photographs, including pictures
taken by the built-in camera plus images loaded from
elsewhere, such as received via e-Mail. Pictures supports
image types JPEG, BMP, GIF, MBM, PNG and WBMP.
Pictures can be viewed in thumbnail and full screen
mode. Thumbnail images may be ordered by name, date,
size or type. In full screen mode the user can browse
through the images and rename or delete them. It is also
possible to send them as e-mail or MMS messages. Simply select a picture, add a message and send just like an
Saved images may be viewed in the image viewer application, and are available for use by other applications in
T610/612 such as MMS and e-mail.
The camera is optimised for ‘point-and-shoot’ speed.
The first press on the CommuniCam button will switch
on the viewfinder. Each subsequent press on the button
will then act as a shutter release and take a picture.
Settings are accessed via softkeys and include: Image
size – Large/Small, default picture name and a flickerfree mode setting.
SMS message or build a slide show with several images
and your favourite sound clips.
Pictures of loved ones can be saved in Contacts. When a
contact calls (or the user calls that contact), the picture is
displayed with the details of the call. This is known as
Picture Phone Book.
Pictures may be loaded up to the Internet. Sony Ericsson
Mobile Internet has an on-line album enabling you to
share pictures and video clips: wap.sonyericsson.com
Multimedia in T610/612
Graphics
Graphics (tables, charts, diagrams and layouts) have a
major impact on the way we work. The T610/612
supports JPEG (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 background colours and the background
picture.

Audio
With the sound recorder function in the T610/612, it is
easy to make a voice recording, for example a personal
rendition of “Happy Birthday”. The audio function in the
T610/612 also allows downloading of sounds and
melodies.
Themes
With themes, the user can change the appearance of the
display, for example the background colours and the
background picture. The phone comes with a number of
pre-defined pictures, and it is possible to download
additional themes. The maximum number of themes is
limited only by the amount of memory.
MMS (Multimedia Messaging Service)
One of the key features in the T610/612 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 T610/612 can contain text, pictures, graphics,
animations, images, audio clips and ring melodies. For
more detailed information, see “Multimedia messaging
service”. For third-party developers’ information, please
visit www.ericsson.com/mobilityworld/ and look for the
MMS Developers’ guidelines.
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.
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 (WCDMA), Multimedia Messaging allows users to send
and receive messages that look like PowerPoint-style
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. An MMS message can contain one or more
of the following:
igure 1. An MMS message can contain images,
usic, audio and graphics.
Tex t
As with SMS and EMS, an MMS message can consist of
normal text. The text can consist of up to 1000
characters. 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.

White Paper T610/612
Templates
The T610/612 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 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”.
Pictures and themes
By using the built-in digital camera in the T610/612
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.
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 T610/612, it is easy to send and
receive business cards, calendar entries and notes.
Business card (vCard)
With MMS in the T610/612, the user can send his/her
business card.
Calendar entry (vCal)
With the vCal function the user can enclose a vCal entry
when sending a meeting request via MMS.
Notes
The T610/612 supports vNote. Notes can be sent via
MMS.
.
Mobile picture transmission also offers inestimable
utility in business applications, from sending on-site
pictures of a construction project to capturing and storing
an interesting design concept for later review. Editing a
picture by adding text allows users to create their own
electronic postcards, an application that is expected to
substantially cut into the traditional postcard-sending
market.
Themes (downloaded or pre-defined) can be exchanged
via MMS.
SMIL presentations
SMIL stands for Synchronized Multimedia Integration
Language and is pronounced “smile”. SMIL in the T610/
612 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

Benefits
Essentially enabling the mobile terminal to serve as
image processor and conveyor, Multimedia Messaging
accommodates the exchange of important visual
information as readily as it facilitates fun. Business and
leisure usage of MMS will be dynamically merged,
resulting in enhanced personal efficiency for users and
increased network activity for operators. In short, MMS
affords total usage for total communication
Because MMS uses WAP as its bearer technology and is
being standardized by 3GPP, it has wide industry support
and offers full interoperability, which is a major benefit
to service providers and end users. Ease-of-use resulting
from both the gradual steps of the messaging evolution
and the continuity of user experience gained from
interoperability is assured.
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.
White Paper T610/612
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-toperson communications solution, meaning that the user
gets the message directly into the mobile phone. He or
she doesn’t have to call the server to get the message
downloaded to the mobile phone. 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.
9
White Paper T610/612
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.
10
EMS (Enhanced Messaging Service)
White Paper T610/612
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.
Sounds and melodies
EMS gives the user the ability to send and receive
melodies. These can be pre-defined sounds, 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
Messaging using EMS
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.
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.
message, and they can be combined with pictures.
Pictures and animations
Phones supporting EMS include a set of pre-defined
animations. New pictures and animations can be
downloaded from the Internet or received in SMS
messages.
Pictures can be created and edited in the phone using a
built-in Picture Editor. Several pictures can be inserted in
one message, and they can be combined with sounds and
melodies.
relevant ETSI/ 3GPP committees. The major mobile
phone manufacturers and most operators are actively
contributing to the 3GPP standards. Hence the EMS
standard has evolved and is now stable and complete as
part of the 3rd Generation Partnership Project (3GPP)
technical specification.
EMS dynamics
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 consumerfriendly standardization.
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.
Standards
The Enhanced Messaging Service (EMS) was first
submitted to the standards committees by Ericsson.
Ericsson presented the outline structure of EMS to the
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
11
White Paper T610/612
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.
Ring signals
Downloading ring signals from the Internet
News & commercials
World news illustrated, sports scores and news headlines,
finance and stock market news with diagrams and
tickers, commercial product promotions, weather reports
with maps, tunes from TV commercials as ring signals.
Info & entertainment
Ring signals, e-greetings, football club logo, joke-of-theday illustrated by pictures or sound, horoscopes, movie
related animation or theme song, TV show promotions,
music artist promotions, lottery results, food and drinks
pictures and 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 WAP, 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.

New and innovative user interface
B
White Paper T610/612
The T610/612 has a new, innovative user interface which
enables the user to manage the phone in an easy and efficient way. Combined with attractive graphics in a wide
variety of styles, the new user interface gives the user a
new and stimulating experience.
The development of the new user interface is founded on
usability tests performed on a wide range of mobile
phones - Sony Ericsson phones as well as competitors’.
The result is a new interface that is easier and quicker to
use than the vast majority in products on the market.
The keys to efficiency
The lay out of the keys are one of many new and
improved elements in the T610/612, helping the user to
find functions and features in the phone quickly and easily. Conveniently and ergonomically grouped together on
the front, the two soft keys, a joystick, the back key and
the C key enable the user to navigate, select and perform
actions.
Actions and options
The left and right soft keys perform the actions shown
immediately above these keys in the display. The most
frequently used actions are always available on the left
soft key. Other actions are accessible on the right soft
key, directly on the key or via the More list. Since most
of the common actions are carried out by the left soft key,
the back key is conveniently placed immediately under
it.
On / Off key
Back and delete
The Back key enables the user to go back one step at the
time. It makes it easy to find the way back, but more
importantly gives the possibility to recover from mistakes. To press and hold the Back key is an instant return
to stand by.
The C key is used to delete items and to turn off sounds:
• Press and hold in Stand by - activate silent mode
• Press and hold during ongoing call - mute
• Normal press during incoming call - mute ring
More Features
The key features in the phone are easily accessible, and
the main menu is reached by a press with the joystick in
stand by. It is also accessible during an ongoing call,
which allows for multitasking - an air time generator.
The main menu gives an overview of all functions and
features in the phone.
Actions in the T610/612 are always carried out in the
most efficient way, and there is always a visible status
bar at the top of the display. The status bar extends the
usage of non voice features by displaying icons and indicators of ongoing actions.
The already popular Themes in Sony Ericsson mobile
phones have been further developed and improved in the
T610/612, enabling the user to personalize the phone
with pictures, colours, wallpapers, etc. The Themes and
all their features are displayed in the large 65 k colour
screen, which gives a unique user experience.

MIDI - Musical Instrument Digital Interface
The T610/612 contains an advanced MIDI composer that
allows the user to compose melodies and ring signals in
polyphonic sound. A MIDI signal or file does not contain
any music. It contains binary data (information) of how a
melody is played and when this data reaches a synthesizer, the synthesizer will translate the binary data to
music, when connected to an amplifier with speakers so
that the sound becomes audible.
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 have limited storage capacity.
MIDI 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 and arrangers.
Polyphonic ring signals
Protocol
The T610/612 has a hardware synthesizer chip, built into
the mobile phone. The software controls the MIDI files,
and makes sure they fit into the hardware chip. It is possible to modify the dynamics, and it is possible to make
the sound escalate, start quietly and grow louder.
The T610/612 Sony Ericsson mobile phone completely
supports the MIDI 1.0 detailed specification. Please visit
http://www.midi.org/ for more information.
Excellent sound quality – 32voices
The human ear can hear sounds from approximately 20
Hz up to 20 KHz. In most GSM mobile phones, the
speech sound range is from 300 Hz to 3400 Hz, which is
good enough for speaking, but quite poor for music. The
T610/612 can handle up to 15000 Hz, equivalent to an
FM stereo radio, which means excellent sound quality.
The quality of the sound heard from the speakers
depends on many different things, for example on the
synthesizer, the amplifier, or the speakers. An important
factor for sound quality is the number of voices. The
human ear cannot separate each voice if the number of
voices increases above about 16, then the voices merge
together. But the nuances in the music increase, and the
music is experienced as more sophisticated if the number
of voices increases. Many modern sound modules in synthesizers used by musicians have 16, 24 or 32 note
polyphony. The number of voices used in the T610/612
is 32, which gives excellent sound quality.
Wavetable synthesis
Sony Ericsson has chosen to implement the Wavetable
synthesis, which consists of sampled real instruments,
which gives a much higher quality than the FM-synthesis. Especially the treble is more distinguished.

Synchronize calendar and phone book
White Paper T610/612
In everyday life, access to an updated calendar and
addresses of friends and business colleagues is greatly
appreciated. To be truly mobile, users must be able to
carry their important information with them. Equipping
mobile phones with Personal Information Manager
(PIM) programs such as calendars, to-do lists and
address books gives users access to their most important
data anywhere and anytime. The information is kept
updated by synchronizing with the information at the
office or at home.
Hierarchical phone book with contacts
The T610/612 features a hierarchical phone book. For
every contact, details such as name, home, work and
mobile numbers, pager number, e-mail address and other
information can be stored. The hierarchical phone book
in the T610/612 is compatible with most groupware and
agenda programs, such as Microsoft Outlook, enabling
smooth local synchronization of contact information
between the phone and a PC, via cable, Bluetooth
wireless technology or IR. For remote synchronization of
Contacts and Calendar over WAP, the T610/612 supports
SyncML.
SyncML, an open standard for remote synchronization in the
T610/612
SyncML – background
The SyncML Initiative Ltd. was founded by Ericsson,
IBM, Lotus, Motorola, Matsushita, Nokia, Palm Inc.,
Psion and Starfish Software in February 2000. Supported
by more than 60 software and hardware developers, the
SyncML Initiative Ltd. seeks to develop and promote a
globally open standard for remote synchronization,
called SyncML. Unlike many other synchronization
platforms, SyncML is an open industry specification that
offers universal interoperability. Because it uses a
common language, called XML, for specifying the
messages that synchronize devices and applications,
SyncML has been called the only truly future-proof
platform for enabling reliable and immediate update of
data. The benefit for the end user is that SyncML can be
used almost anywhere and in a wide variety of devices,
regardless of application or operating system.
the information is stored. For example, a calendar entry
made to a mobile device on a business trip is equally
available to a secretary in a network calendar. SyncML is
the ultimate choice for remote synchronization.
In the T610/612, SyncML supports remote
synchronization of the calendar and phone book,
designed for the requirements of the wireless world
SyncML is designed specifically with the wireless
world’s tight requirements in mind. SyncML minimizes
the use of bandwidth and can deal with the special
challenges of wireless synchronization, such as relatively
low connection reliability and high network latency.
SyncML supports synchronization over WAP, fixed
networks, infrared, cable or Bluetooth wireless
technology.
What is SyncML?
SyncML is the common language for synchronizing all
devices and applications over any network. SyncML
leverages Extensible Markup Language (XML), making
SyncML a truly future-proof platform. With SyncML
any personal information, such as e-mail, calendars, todo lists, contact information and other relevant data, will
be consistent, accessible and up to date, no matter where
In the T610/612, SyncML enables synchronization over
WAP – an ultimate solution for travellers.

Benefits of a common synchronization
protocol
End users
Today’s user of mobile devices probably uses a different
synchronization product with every device. Each technology can synchronize only a few applications, or is
limited to a particular type of network connection. This
arrangement is expensive to install, confusing to configure and operate, and costly to administer. With SyncML,
users will be able to buy devices that synchronize with a
broader range of data.
Device manufacturers
Device manufacturers will benefit from a common protocol that will make the device interoperable with a
broader range of applications, services, and network and
transmission technologies.
Service providers
Service providers moving into the growth area of application hosting are particularly concerned that a proliferation of synchronization technologies will make it
impossible to deploy and support their customers in a
cost-effective manner. To support the range of data types
and devices in use today, service providers must install
and configure multiple server infrastructures, maintain
and support that infrastructure, and maintain compatibility and performance. The alternative now available, to
use a single solution for data connectivity, involves the
risk of a tight coupling to a propriety solution. With SyncML, they will be able to provide connectivity to a wider
selection of applications.
Application developers
Choosing to support multiple synchronization technologies enables an application to support more types of
devices and networked data, but that choice comes at a
cost. With SyncML, application developers will be able
to develop an application that can connect to a more
diverse set of devices and network data.
Network operators
As multiple applications that need remote synchronization over WAP are developed, there will be an automatic
growth of revenue for network operators.

Local synchronization
White Paper T610/612
Open standard
Synchronization is possible with almost any groupware
or office program, since the synchronization method
complies with the open standard IrMC 1.1, as specified
by the Infrared Data Association – reference http://
www.irda.org. IrMC 1.1 brings together the following
standards:
• vCard 2.1 for address book information
• vCalendar 1.0 for appointment and to-do
information
• ObEx (Object Exchange) for data exchange
Bluetooth wireless technology or infrared
The T610/612 synchronizes using the same protocol,
regardless of connection type. It connects via Bluetooth
wireless technology, infrared or cable. The cable is
connected either directly to the phone or to the desktop
charger.
Automatic synchronization
When infrared or Bluetooth wireless technology is
switched on in the phone, the synchronization process
starts automatically, as soon as the phone is within range
of a compatible port on a PC or handheld device (a
suitable synchronization program must be running on the
device).
Intelligent process
A synchronization engine performs the task of
synchronizing. For local synchronization, the
synchronization engine is an application that runs on the
desktop computer. The synchronization engine
compares, updates and resolves conflicts to ensure that
the information in the phone is the same as that in the
computer.
Local synchronization software and the
T610/612
PCs equipped with XTNDConnect PC For Ericsson will
perform synchronization with Microsoft Outlook. For
other groupware environments (Lotus Notes, etc.), the
full version of XTNDConnect PC is required. By using
Bluetooth wireless technology, infrared or the RS 232
Cable, you can easily perform a fast, local
synchronization.
Integration between XTNDConnect PC For Ericsson and
Microsoft Outlook provides an embedded menu for onekey synchronization.
To enhance functionality and compatibility further, the
synchronization software can easily be upgraded.
The number of units that can talk to each other is
unlimited. One phone can be partner with several PCs.
This ensures that information from both the work PC and
the home PC can be synchronized with the phone. For
users that have both a desktop PC and a laptop (free
version XTNDConnect PC) or a PDA (free version
XTNDConnect PC), it is an efficient way to synchronize
data with the phone. This way, data can also be
transferred between PCs to keep them in sync.
If the synchronization software is upgraded to a full
version of XTNDConnect PC, one PC can be partnered
with several different phones. This is vital if, for
example, each member in a work group has his/her own
T610/612, and needs to synchronize with a PC. It makes
it easy, for example, to download a common company
phone directory to the phone book in each company
mobile phone. With the full version of the
synchronization software, other phone types and
handheld devices, such as PDAs and Windows CE
computers, can also be synchronized.

The T610/612 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.
Using the WAP browser
The WAP browser in the T610/612 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 T610/612 is also
designed to access information such as timetables, share
prices, exchange rates, Internet banking and other
interactive services.
The built-in WAP browser in the T610/612 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.
Direct Links
There are direct links in the menu system for easy download of e.g. pictures and melodies from WAP sites.
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 Profile (XHTML-MP),
XHTML Basic, a subset of XHTML-MP, IHTML, WAP
Cascading Style Sheets (WCSS), WML version 1.3 and
WMLScript. The subsets of the WAP standard XHTML
are supported by all major WAP browsers. WAP pages
authored in XHTML and WCSS can be displayed in
standard PC browsers such as IE and Netscape. WAP
pages authored in WML can be displayed in WAP
browsers only. It is preferable, therefore, that developers
use XHTML and CSS to develop content as these are
pure WAP standards. WML and WMLScript are for
backwards compatibility.
All of the basic XHTML and IHTML features are supported, including text, images, links, checkboxes, radio
buttons, text areas, headings, horizontal rules and lists.
For IHTML also blink and marquee, but not tables.
Push services
Businesses and service providers can “push” content or
service indications to work groups and/or customers.
Support for cookies
T610/612 has support for cookies (client based), an
application used by WAP sites to store site-specific
information in the browser between visits to the site.
21
White Paper T610/612
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 ecommerce sites (shopping carts and wish lists).
Style sheets
T610/612 supports style sheets offering content developers more control over the way their WAP pages are displayed.
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.
Adapt to phone type
The User Agent Profile function allows WAP content to
be automatically optimized for the T610/612, ensuring
the intended user experience.
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 T610/612. An XHTML page can be viewed in
both the WAP browser and in any standard Web (HTML)
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 T610/612 has dynamic WAP profile handling, which
means that the user can add, edit and delete WAP
profiles. There are up to 5 WAP profiles.
Several bearer types
The T610/612 accesses the 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.
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
During WAP browsing, the options button 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
White Paper T610/612
The T610/612 accesses WAP services over IP. IP can be
provided either over GSM Data or GPRS, depending on
network services.
Typical differences which distinguish the bearer types
are listed below.
GPRS access
The connection is maintained “constantly”, with data
transmitted in packets, and transmission capacity being
used by the application in use on an as-needed basis.
Higher transmission speed than with GSM Data or SMS
access.
Pricing of GPRS can be dependent on the actual use of
bandwidth, which means the user is charged for the vol-

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.
ume of data transmitted, rather than the duration of the
connection.
When transmitting large amounts of data, bandwidth can
be increased automatically to allow faster transmission
speed.
Ideal for complex pull services, browsing, data transfer,
provisioning, pager services, messaging services, info
services, push initiations.
GSM data access
Circuit connection of data calls, which means that the
phone is connected during the entire WAP session.
Pricing is comparable to that of data calls in the network.
End-to-end gateway navigation
The WAP 2.0 supports E2E (End-to-End) Gateway
navigation, making it possible for example for a bank to
redirect its clients from the Internet gateway to its own
gateway.
Security using the 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 T610/612
indicates when a secure connection is in use.
The T610/612 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.
