WAP Services
Using WAP in the T600/T602
The typical WAP client is a small, portable device
which is connected to a wireless network. This
includes mobile phones, pagers, smart phones,
PDAs and other small devices. In these devices,
you have a limited user interface, low memory and
computing power compared to desktop and laptop computers.
The WAP browser in the T600/T602 is designed
for WML. It is suitable for interaction with customer services, e.g. ticket reservation. It is also
handy when you want to access text-based information, such as timetables, share prices and
exchange rates and Internet banking and other
interactive services.
The WAP profiles
The T600/T602 holds eight WAP profiles, each
with a group of network settings and a homepage.
If you provide a corporate WAP service on your
Intranet, it is useful to enter an Intranet WAP profile in user phones. The WAP profile holds network
settings and user identification. The users switch
between corporate services and WAP services on
the Internet, by switching WAP profile.
Yes, gives the most common options for the function currently in use. The option key also provides
a help menu for certain functions.
The built in WAP browser gives the user portable,
fast and secure access to a wide variety of services, with the possibility of personalized services. WAP in the T600/T602 offers new
opportunities to companies and service providers:
Bearer type
The T600/T602 accesses WAP over a standard
GSM Data connection, including High Speed Data
(HSCSD). (Network-dependent services.)
Connection-oriented
Supporting connection-oriented WAP, the T600/
T602 provides WAP browsing with a high reliability. Connectionless WAP is also supported.
Bandwidth efficiency
One of the key advantages WAP has over textbased HTML pages on mobile devices, is the
bandwidth efficiency of communication. This is
due partly to the fact that the WAP application is
communicated to the wireless devices in the form
of binary encoded data.
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.

mended always to save the page contents as
UTF8, and this is clearly indicated in the pages
before publishing. This ensures that the contents
of the application can be viewed, regardless of
character sets used in gateways and the phone.
All characters are not supported in all phones. The
software version depends on the market the
phone is intended for. Also, please note that the
phone may not support input on a WAP Service
7
which uses certain characters (MMI languages),
even if those characters are supported for browsing in the phone.
Bearer characteristics
The phone accesses WAP services over IP, where
IP is provided over GSM Data.
T600/T602
White Paper, September 2002
GSM data access
•Circuit connection of data calls mean that the
phone is connected during the WAP session.
•Connection-oriented WAP uses error recovery
services to provide high reliability.
•Higher transmission speed than with SMS
access.
•Pricing of GSM data access comparable to
that of data calls in the network.
•Suitable for Complex Pull services, Browsing
and Data transfer.
•Not suitable for Provisioning, Pager service.
•Connectionless WAP can also be used for
those networks that do not support connection-oriented WAP.
Connection-orientated WAP
The T600/T602 supports connection-oriented
WAP over GSM Data. In general, this means that
the connection between the WAP browser in the
phone and the WAP Gateway is maintained in a
session with error recovery services. This gives a
high reliability with a reduced risk of errors in the
transmission, and improves efficiency in WAP
browsing.
Security using WAP
The T600/T602 is based on the WAP 1.2.1 specifications where security functionality is specified
with a technology called Wireless Transport Layer
Security (WTLS).
The WAP protocols that handle the connection, its
transport and its security are structured in protocol layers. The security is handled by the WTLS
layer operating above the transport protocol layer.
The WTLS layer is modular and there are WTLS
classes that indicate which security level is supported by the application.
•WTLS class 1 specifies an encoding of the
information.
•WTLS class 2 includes class 1 and in addition
a server authentication, where server certificates are needed in the phone (access lock)
The T600/T602 supports WTLS class 2.

Over The Air provisioning of
WAP settings
To simplify configuring WAP setting in a number of
phones, all settings can be sent as an SMS message to each phone. This makes it easy for an
operator, a service provider or a company to distribute settings for Internet/Intranet, and WAP,
without having to configure each phone manually.
This also makes it easy to upgrade the services
provided to the users, without the need for users
to perform any manual configuration.
•The OTA configuration message is distributed
via SMS point-to-point.
•The setup information is a binary encoded
XML message. To receive information about
OTA specifications, please contact your local
Sony Ericsson representative for consumer
products.
•The user is not alerted about new settings
until the ongoing browsing session ends. Furthermore, settings are not charged during an
ongoing browsing session.
•The necessary user interaction is limited to
receiving and accepting/rejecting the configuration message, and selecting which WAP
profile to allocate the settings to.
•Security can be handled using a keyword
identifier displayed on the screen as a shared
secret between the SMS sender and the
GATEWAY

receiver. It is important that the user has a
way to verify that the configuration message
is authentic.
Configuration of WAP
settings
To perform the WAP configuration of a single
phone it is suggested to use the functions and
information provided on the Sony Ericsson homepage at http://www.SonyEricsson.com/.
A manual configuration is made using the menu
system in the phone. This is described in the
User’s Guide.
