A case study on multiparty multimedia game development in the IP Multimedia Subsystem

The IP multimedia subsystem (IMS) is the main component of 3G networks. It aims at the seamless provisioning of multimedia services to end-users. This paper presents a case study on multiparty multimedia game development in IMS. It first reviews the APIs and tools available for multiparty multimedia conferencing applications (e.g. games) development in IMS. It then presents the semantics of the game studied in the case and discusses the implementation architecture. The game is a revisited version of the well known capture the flag game. We have developed it with the Ericsson Service Development Studio (SDS) and implemented a prototype. The prototype is described along with the performance measurements. The lessons learned are presented.
