Next Generation Mobile Service Infrastructure Mapping to IMS

This work describes the mapping of a next generation mobile service infrastructure to the IP Multimedia Subsystem (IMS). In the IST project MobiLife, a service infrastructure for the provisioning of next generation mobile services was specified, that supports service adaptation, context awareness, personalization, privacy and trust, operational management and miscellaneous features for service provisioning. This service infrastructure specification is represented by the MobiLife reference model. IMS on the other hand is an industrial relevant platform for telecommunication service provisioning and defines beside the core platform a set of service enablers. The mapping analysis presented here supports in applying the MobiLife service infrastructure to an existing IMS for telecommunication providers. First, the MobiLife reference model is introduced. Then, two possible mapping approaches are discussed, and the mapping of some MobiLife functions to IMS functionalities is described.
