Abstract
Writing protocol software for wireless terminals has been
possible only for equipment manufactures and their
subcontractores. Open operating systems and application
programming interfaces are changing the market, which has
been closed for third-party developers. Today end users
can download and install software tot their mobile
terminals and have gegun to demand new and interesting
applications. At the same time telecommunications
operators are striving for new revenue sources to cover
their investments in third generation mobile network
licenses and infrastructure. This environment possesses
sevelal challenges for software development. The
development cycles must be fast and yet deliver efficient
programs that run on very a restrcted prlform.
Session Initiation Protocol has been chosen as a call
control for Universal Mobile Telecommunications System
release 5. Session initiation Protocol can be used for
creating and managing multimedia sessions. The protocol
is based on open standards and several extensions allow
providing more advanced services, such as messaging and
presence.
This thesis presents an example application of a Session
Initiation Protocol instant messaging extension. The
application is written for Java 2 Micro Edition platform,
which provides a large target market. The application can
be used for testing new services based on Session
Initation Protocol in the today,s wereless data networks.
A software development process and Java protocol
Framework are used for accelerating the development.
