Bearer type characteristics

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-

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.

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 gateway to its own gateway.

Security using the WAP

For certain WAP services, such as banking services, a	• WTLS class 3 – encryption with both server and cli-
secure connection between the phone and WAP gateway	ent authentication.
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 authentica-
tion.
