Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, GrimstadSeveral frameworks are available in 3GPP networks to create mobile services, such as the
Open Service Access (OSA) Application Programming Interface (API) and the native
Session Initiation Protocol (SIP). Each of these frameworks has their own advantages
and disadvantages. Therefore it is important for a service to use a framework which suits
its own requirements as best as possible.
In this thesis we have defined a use case, TMMS Service. This use case has been designed
for four frameworks selected, which are: GPRS, IMS, OSA API and OSA Parlay X Web
Services. We have then evaluated the design of these services against a set of evaluation
criteria. The evaluation criteria cover security, usability, modifiability, reliability,
interoperability and billability.
Our evaluation has proved that none of the frameworks are superior in all areas. The
best framework overall is IMS which provides a lot of end-to-end features and is also
very extensible. One of the biggest disadvantages with IMS is the current lack of a
specific set of documentation for application developers
