COM Support convergences over NGN Chaesub LEE, ITU-T SG 13 Chairman, followed by NGN Signalling and Testing Wei FENG, ITU-T SG 11 Chairman Geneva, 13 -16 July 2009 Fostering worldwide interoperability
Highlight of Current Activities Status of ITU-T SG 13 NGN developments Area Requirements Architecture and Functions Service Subjects NGN (R 1, R 2), IPTV, Mobility Management, Id/Log separation, FMC(IMS), Multicast, VPN, N-ID, OSE, MDS, IPv 6 -NGN, Migration-IPv 6 NGN, Flow State aware-NGN, Accounting-Charging, AAA, Security NGN (FRA R 1), RACF-MPLS (Central, Distributed), NACF, IPTV, Multicast, Id. M, IPv 6 -NGN, Multi-himing-IPv 6, PSTN/ISDNEmulation/Simulation, Loc-MM, HOC, Converged Services, Ethernet-Qo.

Strategic Direction Using connectivity from networks is becoming essential for all human life today and will have more influence in future life Convergence over NGN is one of the best way to mitigate Climate Change, because NGN provide common networking platform for convergences Develop capabilities to support convergences l Detailed Functions in Service Stratum: 4 approaches are now discussed since May NGN-GSI Event l Support Internal Convergences: § FMC/MM: Consent MMCF (Y. 2018) and IMS-FMC (Y. 2808) § IPTV: Content delivery & Storage (Y. CD&S), Info. Delivery Framework (Y. IPTV-IDF), Y. IPTV-TM (Traffic Manag. ) and IPTV Interworking (Y. iptvintwrm) l Support External Convergences: Networked Vehicle (Y. NGNVehicle), Multi. Serv. Cap. in HN (Y. msc-hn-ngn) Geneva, 13 -16 July 2009 Fostering worldwide interoperability 3
Challenges In case of FMC/MM Level of supported services: Voice, Data, Streaming, Video l Level of supporting capabilities: e. g. Seamless Handover * Need consideration between above two l In case of IPTV: see another Doc. In case of Service Stratum l Integrated vs. Distributed and Unified vs. Diverged l Collaboration with Service aspect development In case of external convergences l Clear boundary of NGN involvement l Collaboration with other relevant groups Geneva, 13 -16 July 2009 Fostering worldwide interoperability 4
Next Steps/Actions ITU-T SG 13 should more efforts to develop detailed recommendations for supporting FMC and MM with identifying target service such as “Seamless Voice services over FMC” etc. ITU-T should accelerate development of relevant protocols to support FMC and MM collaborating with related SDOs Joint activities with service related experts group like SG 16 should be encouraged for better development of “Service Stratum in NGN” And it is also recommended joint activity with relevant SDOs to develop recommendations for supporting “External Convergences” Geneva, 13 -16 July 2009 Fostering worldwide interoperability 5
NGN Signalling and Testing Wei FENG ITU-T SG 11 Chairman Fostering worldwide interoperability
ITU-T SG 11 role and mandate Responsible for studies relating to signalling requirements and protocols, including those for IP -based networks, NGN, mobility, some multimedia related signalling aspects, ad hoc networks (sensor networks, RFID, etc. ), Qo. S, and internetwork signalling for ATM, N ISDN and PSTN networks. This also includes reference signalling architectures and test specifications for NGN and emerging networks (e. g. , USN). SG 11 has three lead study group responsibilities on signalling and protocols, on intelligent networks and on test specifications. Fostering worldwide interoperability
Highlight of Current Activities SG 11 has completed NGN Protocol Set 1 which constitute a fundamental basis for initial implementations of NGN release 1: • Signalling architecture for the NGN Service Control Plane (Q. 3030) • Signalling requirements at (SUP-FE) - (I/S-CSC-FE) i/f (Q. Sup. 54), (ASFE) – (S-CSC-FE) i/f (Q. Sup. 55), Organisation of NGN Service User Data (Q. Sup. 56), IEPS communications (Q. Sup. 57 and Amendments to ISUP, BICC and DSS 2 protocols) • Interface control protocols for RACF (Q. 3300 -series) Rs, Rp, Rc, Ri and Rw interface • NGN NNI and UNI signalling profiles (Q. 3401 and Q. 3402) • Signalling requirements and protocol profiles for CRBT and CRT services (Q. 3610 and Q. 3611) • NGN testing for the support of the compatibility of NGN technical equipment and services (Q. 3900, Q. 3901 and Q. 3902) • EAP-based security signalling protocol architecture (Q. 3201) • Authentication protocols for interworking among 3 GPP, Wi. Max and WLAN in NGN (Q. 3202. 1); Requirements and protocol for the interface between a Transport Location Management PE and a Policy Decision PE (Ru Interface) (Q. 3223) Fostering worldwide interoperability
Strategic Direction Accelerate study on: Monitoring parameters for NGN protocols Service test specification for NGN Qo. S tests specification for NGN USN and RFID test specification Coordination of work on Emergency Communications within an NGN environment Security Coordination For NGN Protocols Consider, in collaboration with ISO/IEC JTC 1/SC 6 standards for end-to-end multicast Fostering worldwide interoperability
Challenges More coordination and cooperation with other SDOs such as 3 GPP, IETF, ETSI, ATIS, IEEE, etc. Complementary and consistent with outputs from other SDOs. More work focusing on testing, Qo. S, Network attachment, Service and application and Emergency Telecommunications, etc. New signalling and protocols work related to IPTV, M 2 M, etc. Fostering worldwide interoperability
