  1. ITU-T Study Group 11Signalling Requirements and Protocols Yukio Hiramatsu

  2. Contents • Terms of reference • Management Team • SG Organization • Statistics • Highlights of achievements • Workshops • Future work • Conclusions

  3. Terms of Reference • Signalling Requirements and Protocols • for Internet Protocol (IP) related functions, some mobility related functions, multimedia functions and enhancements to existing Recommendations on access and internetwork signalling protocols of ATM, N-ISDN and PSTN. • Lead SG for: • Intelligent Network

  4. Management Team (i)

  5. Management Team (ii)

  6. Study Group Structure • WP1 Application of ININ requirements and protocols, and API • WP2 Requirements for IP and advanced Network ApplicationsSignalling requirements for BICC and IP based network • WP3Engineering of BICC and Legacy SignallingProtocols for BICC and IP based network • WP4Engineering of AAL 2 Signalling and Common Signalling ProtocolsCommon transport and AAL Type 2 / IP bearer protocols

  7. Statistics (I) • 7 SG meetings held • 1 WP meeting held (WP4/11) • 11 Rapporteurs meetings held including 3 E-meetings • 640contributions received • Max/Min/Average SG participants : 202/94/130

  8. Statistics (II) • 115New/Revised Recommendations approved • 26 New/Revised Q-Series Supplements approved • 14 Implementers guides approved • 15 Questions assigned by WTSA-2000 • 3 New or revised Questions during study period • 7 Questions proposed for next period

  9. Highlights of achievements (I) • IN work completed with approval of CS4 (Interworking with IP) (Q.124x-series) • BICC CS2 (support of IP bearer) approved. BICC CS2 was adopted by the 3GPP. BICC CS3 (further enhancement) progressed. (Q.1902-series, etc.) • Support of International Emergency Preferential Service (IEPS) step1 approved. (Amendments to the existing ISDN, B-ISDN, SS7 and BICC protocols)

  10. Highlights of achievements (II) • Interworking between SIP – BICC/ISUP CS1 approved. (Q.1912.5) • ATM over MPLS signalling progressed. (Amd Q.2920) • Control of signal processing equipment and common transport control enhanced. (Q.50-series, Q.115-series, SCCP and STC) • AAL2 and IP connection control signalling progressed. (Q.263x-series) • NGN related protocol work has been started. (TRQs on IP Tel, API and NCAP)

  11. Workshops (I) • NGN Workshop / 9-10 July 2003 / Geneva(jointly organized with SG13) • Participated 5 workshops organized by other SGs (IP+Mediacom 2004, Security, IP+Optical, TDR, Home Network)

  12. Future Work (I) • Signalling requirements and protocols for convergence toward NGN • Service control protocols • Call and session control protocols • Resource management and control (including QoS) • Bearer (user plane) control protocols • Assistance for a handbook on the deployment of packet based network

  13. Future Work (II) • Further enhancements to the existing protocols for: • Interworking of BICC/ISUP/DSS1 with SIP • Signalling requirements for IEPS • Signalling requirements for end-to-end IP-QoS • BICC additional capabilities • Common signalling transport protocols and AAL2/IP bearer control signalling

  14. Acknowledgements • Vice Chairmen and Working Party Chairmen and Vice Chairmen • Coordination representative for SSG/3GPP (Mr. A. Heidemark, Sweden) • IEPS Coordinator (Mr. W. Lange, Germany) • Security Coordinator (Mr. G. Zebarth, Canada) • Rapporteurs and Editors, and collaborators • TSB (Engineer-Arshey Odedra, Assistants-Isabelle Frost and Antonella Maffi)

  15. Conclusion • SG11 has been responding to the industry as the centre of excellence for signalling and protocol work for global standards regarding PSTN, ISDN, ATM and IP based network. • This function of SG11 will be a key to the success in defining Recs on further enhancements to the existing networks and their convergence toward NGN.

  16. Mr.Yukio Hiramatsu He is Senior Manager of NTT Intellectual Property Center. He is active in the ITU-T since 1985. Since October 2000 he has been serving as Chairman of Study Group 11 (Signalling requirements and protocols). Prior to this he served in Study Group 7 (Data communications and OSI) from 1996 to 2000 as Vice-Chairman of Study Group 7 and Chairman of Working Party 2/7 dealing with network interfaces. Among his major achievements are completed BICC Recs already adopted by the 3GPPs and the ongoing signalling protocols work on NGN (next Generation Networks).
