Highlights from Presentation 1 Service requirem ents and capabilities ITU-T o NGN Release 1 environment obj ectives, services, and capabilities were introduced with brief comparison with ETS I TIS PAN Release 1 work with respect to services, access network, QoS , and evolution towards NGN. o S tudy subj ects for interconnection between NGN domains and user networks and equipment were summarized. o Future work items includes consideration about multiple service scenarios, customer and enterprise networks, more services, service delivery platforms, profiling, interconnection etc. I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 2
Highlights from Presentation 2 Basic Architecture and I nteresting I ssues ITU-T o NGN definition, general reference model, and mediated/ non-mediated service concept were introduced. o Effects of separation into service and transport strata were examined and resource and admission control was identified as the bridging function. o Architectural aspects on fixed to mobile convergence and home gateway architecture/ functionality were emphasized for more work. o Areas for further study are streaming services (IPTV), identity based systems (RFID), and home networks.

Highlights from Presentation 3 I MS based NGN Architecture and its application ITU-T o IP Multimedia S ubsystem (IMS ) were introduced with key components; CS CFs and HS S . o How to adapt IMS to NGN was summarized and application to PS TN emulation service (PES ) was examined. o Advantages of IMS PES are 1) preserves common interface to RACF & transport network, 2) common service control functions, 3) common Routing and configuration data between emulated PS TN/ IS DN Users and NGN Users (Important), and 4) economy of scale.

Highlights from Presentation 4 Mobile Applications and Services for NGN netw orks ITU-T o Trends for service revenue are headed for multimedia, contextual/ personal awareness, and social and community focused. o Open Mobile Alliance (OMA) organization and its S ervice Environment (OS E) was introduced. o Developed service architectures under OMA are presence, group management, and Push-to-Talk over cellular. o Ongoing service developments include messaging, content-related services (content screening, dynamic content delivery, and digital rights management), and delivery mechanism such as mobile broadcast I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 5
CONCLUSI ONS ITU-T o S ervice enablers/ capabilities and their coordination with other organizations need further work in ITU-T. o How to accommodate expected new services such as streaming (IPTV) needs action with regard to the NGN capabilities and architecture. o The approach would be in fact identifying basic capabilities and comparing with already-defined architecture elements. o To what extent the NGN architecture should be common is for further study. Existing specification/ equipment should be taken into account. Interworking may be the first step from the practical view point.
