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 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).
