Next generation networks promise new user-centric applications and services. This requires more than a combination of diverse technologies - it requires new functionality. Context-awareness is one example of new functionality, and refers to the set of characteristics and behaviour that make a system aware of its user's state and the state of the network environment. This paper first surveys several research challenges from the next generation networks supporting services, and then introduces the policy-based paradigm for cross-layered service management interoperability in autonomic computing environments integrating context information in the management operations of pervasive services. A novel policy-based context model is then defined that is suitable for managing services in cross layered environments using the DEN-ng information model and ontologies. This model extends the functionality of previous solutions for managing context-aware services. Finally a representative Internet and Broadcasting Systems Convergence application scenario inspired by seamless mobility is presented for providing insight on future directions and applications in both the cross-layer interoperability of the systems and NGN area.
