Evaluation of frameworks for creating end-to-end mobile services with OMA MMS as a use case

Page i of x i. Abstract Several 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.
