ITU-T

• 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.

• S

tudy subj ects for interconnection between NGN domains and user networks and equipment were summarized.

• Future work items includes consideration about

multiple service scenarios, customer and enterprise networks, more services, service delivery platforms, profiling, interconnection etc.

ITU-T

• NGN definition, general reference model, and

mediated/ non-mediated service concept were introduced.

• Effects of separation into service and transport

strata were examined and resource and admission control was identified as the bridging function.

• Architectural aspects on fixed to mobile

convergence and home gateway architecture/ functionality were emphasized for more work.

• Areas for further study are streaming services

(IPTV), identity based systems (RFID), and home networks.

ITU-T

• IP Multimedia S

ubsystem (IMS ) were introduced with key components; CS CFs and HS S .

• How to adapt IMS

to NGN was summarized and application to PS TN emulation service (PES ) was examined.

• 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.

ITU-T

• Trends for service revenue are headed for

multimedia, contextual/ personal awareness, and social and community focused.

• Open Mobile Alliance (OMA) organization and its

S ervice Environment (OS E) was introduced.

• Developed service architectures under OMA are

presence, group management, and Push-to-Talk

• ver cellular.
• Ongoing service developments include messaging,

content-related services (content screening, dynamic content delivery, and digital rights management), and delivery mechanism such as mobile broadcast

ITU-T

• S

ervice enablers/ capabilities and their coordination with other organizations need further work in ITU-T.

• How to accommodate expected new services such

as streaming (IPTV) needs action with regard to the NGN capabilities and architecture.

• The approach would be in fact identifying basic

capabilities and comparing with already-defined architecture elements.

• 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.
