Service continuity management through an E2E dynamic session in NGN

During the past two decades, the evolution in the field of telecommunication has been driven by two interrelated trends: NGN (heterogeneity and mobility) and user centric (user preferences, location and activity). Service continuity management is highlighted as the key requirement regarding all these inputs. In SOA and EDA based architecture, we propose an E2E dynamic session binding as a temporal E2E connectivity binding of each level´s elements (users, terminals, access networks, core networks and service components). It permits, from the user centric vision, the dynamic association of these elements according to their mobility. With this intention, we propose several management entities: community self management, information inference (Infoware) and NGN Sessioware which depend on seamless userware and serviceware. We detail our propositions with a complete scenario integrating the two trends.
