White Paper T630/T628
30 October 2003
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 T630/T628 has dynamic WAP profile handling,
which means that the user can add, edit and delete
WAP profiles. There are up to 5 WAP profiles.
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
The T630/T628 accesses WAP services over IP. IP
can be provided either over GSM Data, HSCSD or
GPRS, depending on network services.
Typical differences which distinguish the bearer
types are listed below.
High Speed Data
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.
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 volume of data transmitted, rather than the
duration of the connection.
When transmitting large amounts of data, band-
width 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 ses-
sion.
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-to-End) Gateway
navigation, making it possible for example for a
bank to redirect its clients from the Internet gate-
way to its own gateway.
