White Paper T310/T312
18 January 2003
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 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 T310/T312. An
XHTML page can be viewed in both the WAP
browser and in any standard Web 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 T310/T312 has dynamic WAP profile handling,
which means that the user can add, edit and delete
WAP profiles. The T310/T312 has a maximum of 5
WAP profiles.
During WAP browsing, the options button on the
T310/T312 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
The T310/T312 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
• Data is transmitted in packets, with transmis-
sion 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 for example be dependent
on the volume of data transmitted, rather than
the duration of the connection.
• Ideal for complex pull services, browsing, data
transfer, provisioning, pager services, messag-
ing 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.
Gateway characteristics
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.
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.
