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 T20e is compliant with WAP 1.1
including security according to WTLS class 2. It is designed for WML and cannot read ordinary
HTML pages, but 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 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 T20e offers new opportuni­ties to companies and service providers:

Bearer types The T20e accesses WAP over a standard GSM Data connection as well as

Connection-oriented Connection-less or connection-oriented WAP can be selected by the user.

Bandwidth efficiency One of the key advantages WAP has over text-based HTML pages on

ee

over SMS. (Network-dependent services.)

Connection-oriented WAP provides browsing with a high reliability.

mobile devices, is the bandwidth efficiency for 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.

Creating WAP services Creating a WAP service is no harder than creating an Intranet/Internet

service today since WML and WMLScript are based on well-known
Internet technology. New market segments can be addressed by launch­ing innovative mobile Value Added Services.

Using standard tools It is possible for the service creator to use standard tools like ASP or CGI

to generate content dynamically. You can utilize existing investments in
databases etc. that are the basis of existing Internet services. Create a ser­vice once and make it accessible on a broad range of wireless networks.

Maintain customer base You can adapt existing Internet services to WAP. The actual binary

encoding can be handled by the WAP Gateway which makes it possible
to create WAP applications using the text-based language WML and
other tools. In fact, existing HTML-based applications on the Internet can
be viewed in the WAP browser, if an automatic conversion is performed
in the WAP Gateway.

Improve productivity Improve and simplify the communication flow within an organization by

making information available to mobile users. A company or organiza­tion can use a WAP gateway to provide a secure connection to the com­pany network for their users.

The WAP profiles The T20e holds several WAP profiles, each with a group of network set-

tings and a home page. 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 easily between the corporate services and WAP services on the
Internet, simply by switching WAP profile.

The WAP Gateway provides services in the company’s Intranet, a banking or stock trading ser­vice on the Internet, or access to other WAP applications on web addresses anywhere on the
Internet. A Gateway is identified by an IP number or by a phone number, depending on access
type.

The T20e supports both connection-less and connection-oriented WAP over GSM Data. The
user can select which method to use. In general, connection-oriented 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.

SSSSeeeeccccuuuurrrriiiittttyyyy UUUUssssiiiinnnngggg WWWWAAAAPP

The T20e is based on the WAP 1.1 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).

• WTLS class 3 includes class 2 and in addition a client certification, where client certificates
are needed for the user (signature lock).

The T20e supports WTLS class 2, and it is equipped with a number of certificates. An access
lock is needed when accessing certain WAP sites. The user is asked to enter it before a secure
WAP connection is established.

To simplify configuring WAP settings 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, according to WBXML. To
receive information about OTA specifications, please contact your local Ericsson representa­tive for consumer products. A configurator that utilizes OTA provisioning can be tested on
the Ericsson Mobile Internet

• The user is not alerted about new settings until the ongoing browsing session ends. Further­more, settings are not changed 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 receiver. It is important that the user has a way to verify
that the configuration message is authentic

For a company or an organization, it can be useful to restrict phone calls. Fixed Dialling allows
you 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. Check with your Operator about this
feature.

Restricted calls allows you to block outgoing or incoming calls in certain situations, for exam­ple international calls.

The SIM Application Toolkit (SIM AT) is a smartcard-centric method of deploying programs
that apply only to GSM and to SMS and USSD transports. Programs must be distributed on
smartcards. WAP is an Internet-centric method of deploying programs that is independent of
network technology. Programs and content are kept centrally on web servers and downloaded as
required. While there is some overlap, WAP is a particularly good choice when deploying pro­grams that also have an HTML version for desktop use. Work is currently underway 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 the users over the air, directly to their phones. In the
T20e, 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 for the user.

Data (CSD) and SMS.

Bookmark A URL and header/title stored in the phone.

Browsing session From the first access of content until the termination of the connection.

Calling Line
Identification (CLI) Shows the number of the person calling you in your mobile phone dis-

play. You can then make an informed choice as to whether or not to
take the call. Bear in mind that not all numbers can be displayed. To
use this service, it must be supported by your network.

for telephone banking, accessing an answering machine, etc.

e-GSM Extended GSM, e-GSM, are new frequencies specified by the Euro-

pean Radio communications Committee (ERC) for GSM use when
additional spectrum is needed (Network-dependent). It allows opera­tors to transmit and receive just outside GSM’s core 900 frequency
band. This extension gives increased network capability, which favours
both the user and the operators.

EFR Enhanced Full Rate, speech coding.

EMS Enhanced Messaging Service, an enhancement of the SMS standard.

This makes it possible to include pictures, melodies, sounds and ani­mations in messages, and also to receive and edit new pictures and
melodies on the phone.

ETSI European Telecommunications Standards Institute.

FR Full Rate, speech coding.

Gateway A WAP Gateway typically includes the following functions:

- A Protocol Gateway – the protocol gateway translates requests from
the WAP protocol stack to the WWW protocol stack (HTTP and TCP/
IP).

- Content Encoders and Decoders – the content encoders translate Web
content into compact encoded formats to reduce the size and number of
packets traveling over the wireless data network.

GSM Global System for Mobile Communications. GSM is the world’s most

widely-used digital mobile phone system, now operating in over 100
countries around the world, particularly in Europe and Asia-Pacific.

GSM 900 The GSM systems family includes GSM 900, GSM 1800 and GSM

1900. There are different phases of roll-out for the GSM system and

22

GSM phones are either phase 1 or phase 2 compliant.

GSM 1800 Also known as DCS 1800 or PCN, this is a digital network working on

a frequency of 1800 MHz. It is used in Europe and Asia-Pacific.

can be stored and accessed by name or position.

PIM Personal Information Management.

Service Provider A company that provides services and subscriptions to mobile phone

users.

SIM card Subscriber Identity Module card – a card that must be inserted in any

GSM-based mobile phone. It contains subscriber details, security
information and memory for a personal directory of numbers. The card
can be a small plug-in type or credit card-sized but both types have the
same functions. Your phone uses the small plug-in card.

SMS Short Message Service. Allows messages of up to 160 characters to be

sent and received via the network operator's message centre to your
mobile phone. Messages are stored if the phone is off or out of reach
ensuring that they reach you. To use this service, it must be supported
by your network.

WAP Wireless Application Protocol. Handheld devices, low bandwidth,

binary coded, a deck/card metaphor to specify a service. A card is typi­cally a unit of interaction with the user, that is, either presentation of
information or request for information from the user. A collection of
cards is called a deck, which usually constitutes a service.

WAP Application A collection of WML cards, with the new context attribute set in the

entry card.

WBMP WAP Bitmap.

WDP Wireless Datagram Protocol.

WML Wireless Markup Language. A markup language used for authoring

services, fulfilling the same purpose as HyperText Markup Language
(HTML) does on the World Wide Web (WWW). In contrast to HTML,
WML is designed to fit small handheld devices.

WMLScript WMLScript can be used to enhance the functionality of a service, just

as for example JavaScript may be utilized in HTML. It makes it possi­ble to add procedural logic and computational functions to WAP-based
services, for example.
