SPICE: Evolving IMS to Next Generation Service Platforms

Today's wireless and mobile services are typically monolithic and often centralized in nature, which limits heterogeneous service access and shared service usage. New sources of revenue for providers are expected to include tailored, personalized, and dynamically composed services that are fast to market, cost efficient, and provide compelling user experience. To meet these market needs, the SPICE service platform extends the IP multimedia subsystem (IMS) by supporting added-value services that are composed of more basic services. The platform is presented through the architecture and through scenarios showing the interactions between the platform and its service components. We describe the IMS role and functions in SPICE, and the use of ontology and semantic Web technologies for integrated knowledge management in such mobile service platforms
