Session 2 – New Generation Service Challenges Objectives: Develop a common understanding of the present and future MM-services driven by the fix-mobile-broadcasting convergence Identify the impact of these trends on the NGN concept, in particular on the service and network architectures and their interfaces Define the service relative issues of the technical standardization roadmap Workshop on Next Generation Networks: What, When & How? 9-10 July 2003

Session 2 – New Generation Service Challenges Conclusions (1): New generation of services Large set of MM-services (VAS) Trend to customized VAS (e.g. QoS) Importance of group communications Peer-to-peer communications (including user’s content generation) Embedded services (Sensors, RFID) MM-services features: - Mobility, roaming - Bandwidth - Security - … Workshop on Next Generation Networks: What, When & How? 9-10 July 2003

Session 2 – New Generation Service Challenges Conclusions (2): Impact on the NGN concept and S+N Architectures: CPE (HME) to be included, Access technologies independent, Support the different business models (SP,NP, CP), Open Service Architecture concept, Allow network evolution, Increase flexibility and reduce complexity for the customers through Ambient Intelligence, Support convergences (fix/mobile/broadcasting), Address content related issues (DRM, Metadata,..) … Workshop on Next Generation Networks: What, When & How? 9-10 July 2003

Session 2 – New Generation Service Challenges Proposed action: Analyze existing Services and Network Architectures and their suitability to support the next generation of MM-services - in particular the interface between the two models – and further develop the models towards target NGN-Service and NGN-Network Architectures Workshop on Next Generation Networks: What, When & How? 9-10 July 2003

Session 2 – New Generation Service Challenges A3 = U - Any MM services -Any time -Anywhere = Ubiquitous Network ? Workshop on Next Generation Networks: What, When & How? 9-10 July 2003
