With the advent of Web services and dynamic service composition, flexible and adaptable complex services may be realized. Assuming that such services have been provided with all the necessary service orchestration and end user information, simple services may be enhanced with contextual information, such as location, presence and user preferences, to provide a more tailored experience for the end user.
Mobile next generation service environments include many functional components suitable for the provision of contextual data with which to build tailored and complex services for subscribers. Specifically, the IP Multimedia Subsystem (IMS) defined by 3rd Generation Partnership Project (3GPP) and its enablers provide an interesting environment for researching techniques for the composition and delivery of complex context-specific personalized and community services to mobile users.
In this paper we discuss our ongoing research into dynamic service composition for mobile communities. As such, we investigate community-based mobile entertainment services, their provisioning requirements, enablers, and dynamic composition of group-specific real-time next generation packet mobile services. To the end, we have developed a service platform called the Group Entertainment Service platform (GESP) for IMS that we describe in detail.
