  5. WGs Studying NGN-related Technologies (1) • BB & IP-based Network Upstream WG • 　ITU Upstream：　International Standardization Activities on Broadband 　　　　　　　　　　　　　　　　　　　& IP based network • IP Telephony：　Coordination with other SDOs on IP Telephony - Activities on TIPHON, TISPAN • Signaling WG • SWG2 - MEGACO：　Activities on ITU-T SG16, IETF MegacoWG, JT-H248.1 Revision • SWG3 - SIP： TS on SIP-ISUP inter-works • Network Management WG • O&M on Telecommunication network SWG：　 Activities on NGN Network Management Technology(2004) • IP Phone Speech Quality Evaluation SWG： GSC9, Seoul

  6. WGs Studying NGN-related Technologies (2) • Multimedia Platform WG • H.323 Networking SWG： H.323 Security SWG： H.323 Mobility SWG：　 H.323 QoS SWG： H.323 System SWG： - Cooperation with AVS Upstream WG • Enterprise Network WG • Enterprise Network Interface SWG： Activities on IP-QSIG • CTI/F SWG：　Activities on CSTA (Services for Computer Supported Telecommunications Applications) • IP-based IMT Platform WG • All IP-NW Standardization(3GPP) • NW-vision, capability requirements, architecture GSC9, Seoul

  7. NGN-Related Standardization at TTC • JT-H248.1 Media Gateway Control Protocol（MEGACO) • JT-H323　　　 Packet Based Multimedia Communications Systems • JT-H450.xx JT-H323 Related (LAN) • JJ-201.01 A method for Speech Quality Assessment of IP Telephony • TS-1002 Technical Specification on SIP to TTC ISUP Inter-working • TS-1003 Specification on Interconnection of SIP Networks • TS-1004 Specification on Network Asserted User Identity 　　　Information Transferring through SIP Networks GSC9, Seoul

  8. NGN-related Survey/Reports in TTC March 2002 NGN Study Report 1 by TTC March 2003 NGN Study Report 2 by TTC August 2003 NGN Study AG Formed - consisting of TTC members; - studies activities in SDOs/Fora including ITU-T, ETSI, ANSI, T1 and ISOC; - recommends standardization strategies by March 2004. GSC9, Seoul

  9. Report of TTC NGN Study AG(1) Recognizing • ITU-T is developing NGN architecture related recommendations under the NGN-2004 project; • NGN architecture references IMS of 3GPP which may lead the way to FMC realization; • ITU-T SSG will study the relation between IMT-2000 and beyond and NGN in the next study period; • Regional/National SDOs have also started the study: TISPAN of ETSI Telecommunication Network Committee of TTA VoIP signalling by ATIS/T1 GSC9, Seoul

  10. Report of TTC NGN Study AG(2) Recommends • TTC to expand the existing NGN Study AG to include chairman of NGN related working groups, e.g., architecture, signalling, network management, multimedia and IP-based IMT Platform(3GPP & 3GPP2) WGs ; • to continue the survey of NGN related activities of ITU-T, Regional/National SDOs and Fora; • and to propose the NGN standardization strategy to TTC Strategy Committee(SC).
