White Paper J200
13 November 2004
Improve productivity
Improve and simplify the communication flow
within an organization by making information avail-
able to mobile users. A company or organization
can use a WAP gateway to provide a secure con-
nection to the company network for their users.
The WAP profiles
The J200 holds up to five WAP profiles, each with a
group of network settings 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. Users can easily switch
between corporate services and WAP services on
the Internet, simply by switching WAP profile.
Connection-orientated WAP
The J200 supports connection-oriented WAP over
GSM as well as GPRS 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 provides
high reliability with a reduced risk of errors in trans-
mission, and improves efficiency in WAP browsing.
Bearer type characteristics
The J200 accesses WAP services over IP. IP can be
provided either over GSM Data or GPRS, depend-
ing on network services.
Typical differences that distinguish the bearer types
are listed below.
GSM data access
• Circuit connection of data calls, means that the
phone is connected during the entire WAP ses-
sion.
• Pricing is comparable to that of data calls in the
network.
GPRS access
• The connection is maintained “constantly”, with
data transmitted in packets, and transmission
capacity of the application in use on an as-
needed basis.
• GPRS offers 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.
• While 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, messag-
ing services, info services, push initiations.
Security using WAP
The J200 supports WAP 1.2.1, a version of the
Wireless Application Protocol that includes WTLS
class 2.
While using certain WAP services, the user may
want more security than normal, for example when
using banking services. The user establishes a
secure connection between the phone and the
WAP gateway.
