1 Summary of Results Study Period ITU-T Study Group 11 Signalling Requirements and Protocols Yukio Hiramatsu

2 International Telecommunication Union 2 ITU-T Study Group 11 Signalling Requirements and Protocols Contents Terms of reference Highlights of achievements Future work Supplemental slides

3 International Telecommunication Union 3 ITU-T Study Group 11 Signalling Requirements and Protocols Terms of Reference Responsible for studies relating to signalling requirements and protocols for Internet protocol (IP) related functions, some mobility related functions, multimedia functions for networks including convergence toward NGN, and enhancements to existing Recommendations on access and internetwork signalling protocols of BICC, ATM, N ISDN and PSTN. Lead SG for: – signalling and protocols – intelligent networks

4 International Telecommunication Union 4 ITU-T Study Group 11 Signalling Requirements and Protocols Highlights of achievements (I) 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) Signalling requirements at (AS-FE) – (S- CSC-FE) i/f (Q.Sup.55)

5 International Telecommunication Union 5 ITU-T Study Group 11 Signalling Requirements and Protocols Highlights of achievements (II) Organisation of NGN Service User Data (Q.Sup.56) Signalling requirements to support the emergency telecommunications service (ETS) in IP networks and protocol extensions for the support of IEPS communications (Q.Sup.57 and Amendments to ISUP, BICC and DSS2 protocols) NGN NNI and UNI signalling profiles (Q.3401 and Q.3402)

6 International Telecommunication Union 6 ITU-T Study Group 11 Signalling Requirements and Protocols Highlights of achievements (III) Interface control protocols for RACF (Q.3300-series) – Rs, Rp, Rc, and (PD-PE) – (PE-PE) interface Interworking between ATM and IP-based networks (Q.3150/Y.1416 and Q.3151/Y.1417) NGN testing for the support of the compatibility of NGN technical equipment and services (Q.3900, Q.3901 and Q.3902)

7 International Telecommunication Union 7 ITU-T Study Group 11 Signalling Requirements and Protocols Highlights of achievements (IV) Work was progressed in cooperation with ITU-D for development of a handbook for deployment of packet based networks (a Q.Sup. expected at the next SG11) Network Attachment Control Signalling Requirements and Protocols. – EAP-based security signalling protocol architecture (Q.3201) Note – EAP: Extensible Authentication Protocol – Authentication protocols for interworking among 3GPP, WiMax and WLAN in NGN (Q )

8 International Telecommunication Union 8 ITU-T Study Group 11 Signalling Requirements and Protocols Future Work (I) All Questions require continuation in order to address various additional features and consider initiating work in the scope of an NGN Protocol Set 2 (e.g., IMS, IPTV, WiMAX, RFID). – Signalling architecture and requirements. – Session control requiring further work on SIP-based profiles to improve interoperability at UNI and at NNI, as well as for supporting more services and applications; – Bearer control for support of IPTV and multicast data delivery services, for support of more efficient transfer capabilities such as flow state aware transfer capability; – Resource control for developing additional interface protocols fitting with the RACF enhanced architecture. – Coordination with regional SDOs including development of a handbook to assist ITU-T members in the deployment of packet-based networks to support PSTN/ISDN services

9 International Telecommunication Union 9 ITU-T Study Group 11 Signalling Requirements and Protocols Future Work (II) – NGN network attachment and identification for support of a wider range of access technologies and mobility management requirements. Some new Questions are required to accelerate study on: – Monitoring parameters for NGN protocols – Service test specification for NGN – QoS tests specification for NGN – USN and RFID test specification – Coordination of work on Emergency Communications within an NGN environment – Security Coordination For NGN Protocols

10 International Telecommunication Union 10 ITU-T Study Group 11 Signalling Requirements and Protocols Conclusion SG11 produced a significant number of NGN Protocol Set 1 related Recommendations during the current study period. These Recommendations constitute a major reference to enable actual NGN implementations (Release 1). Various Supplements have been published to document the corresponding NGN Signalling requirements. NGN Protocol Set 2 and more should continue to be developed during the forthcoming Study Period ( ) based on the new requirements and feedback from first NGN release implementations.

17 International Telecommunication Union 17 ITU-T Study Group 11 Signalling Requirements and Protocols Thank you! Yukio Hiramatsu is Professor, Graduate School of Intellectual Property, Osaka Institute of Technology. He was with NTT from 1978 to Active in the ITU-T since 1985, he has been serving as Chairman of Study Group 11 (Signalling requirements and protocols) since October Prior to this position, he served in Study Group 7 (Data communications and OSI) from 1996 to 2000 as Vice-Chairman of the Study Group and Chairman of Working Party 2/7 dealing with network interfaces. Among his major achievements are completed BICC Recommendations already adopted by the 3GPPs and the ongoing signalling protocol work for the NGN (Next Generation Networks).
