  2. Scope and ToR Service requirements Environments analysis Continuation of GII Implementation issues Role of ITU-T and SG 13 Contents

  3. 1. Scope and ToR • Make common understanding of what is next step • Beyond IP • Continue with IP Target Time • Try to sketch it brief as requirements • Services and Environments • Horizontal and Vertical views • Find contribution area and work items • Standard areas • Other SDOs • Role of ITU-T and SG 13

  4. 2. Service requirements Moving Trend of Service Requirements FAX Image/Video WEB Vo IP Vo ATM Vo MPLS Vo DSL Vo Ethernet Telex Data FAX Voice FAX Voice Voice mid 1970 ~ 1980 mid 1980 ~ 1990 mid 1990 ~ today

  5. Service Requirements in Near Future ? Tele-gaming VHE (Ethernet) or (others) Impact Multimedia Chatting Packet Voice Others (?) CAMCORDER with Ethernet

  6. Requested Target Services for Next Until 2004 after 2004 ~ 2008

  7. Full Open and Competition Environments Telecom. Business Tele-Broadcasting Business Broadcasting Business Voice Data inc. Voice End to End Client to Server Data Integrated Service User friendly control Packet based transport Circuit based Optic based transmission Electronic based Integrated Telecommunication Infrastructure 3. Environments Analysis Change of Environment

  8. Network Evolution Trends • Optical Infrastructure • Capacity imperative • Packet Based Transport & Switching • Multi-service flexibility • Location of Intelligence (Core vs Edge) • QoS and Bandwidth Granularity/Control • Convergence of Control & Management Aspects • E.g., Dynamic routing vs protection switching • Interworking with Legacy Systems

  18. C.S. LEE’s stupid idea No. 1 to be implemented in NGN New Standards on Access ADSL Voice + DATA Full DATA Data inc. Voice

  19. Points of Intelligence 3.1 kHz Audio Bearer Network Application Server A.N A.N Core Network 64 kbps CM/PM Bearer Network A.N QoS 3 ~ 2 Mbps FM Bearer Network Access Net. Part QoS 2 Policing Server QoS 1 ATM Bearer Network QoS 1 A.N IP Bearer Network • Same service but different path • Use current bearer networks in • Multimedia era with integrated • Access Network

  20. C.S. LEE’s stupid idea No. 2 to be implemented in NGN New Signaling Mechanism or Protocol Core Net (Various Bearer) Integrated Access Unit (e.g. NGN Set Top Box) Intelligent Access Server

  21.

  26. 6. Role of ITU-T and SG 13 Packet based infrastructure IP Issues • Application of IP technology into Telecom infra and • specify Interworking between IP and Telecom • service/network • New architecture for full Packet based infrastructure (inc.Voice) • Migration path from Circuit based to Packet based infra (inc. Interworking) • Service and network capabilities for providing Packet based services • New access technology, OAM and Performance study based on full Packet infra

  27. ITU-T Activity Functional Model 64kbps based ISDN Ref. Config.
