  1. NGN Architecture and Release 1 Definition (Agenda Item 4) Richard BrennanVice-Chair ETSI TISPAN & Chair TISPAN WG-2 pulver.com rbrennan@pulver.com Dick KnightChair TISPAN WG-1 BT Group plcdick.rr.knight’bt.com TISPAN-3GPP Workshop - Sophia-Antipolis

  2. Agenda • Approval of agenda and Documents (s1) • Workshop objectives (s1) • 3GPP and TISPAN organisation (s1) • NGN Architecture & Release 1 definition (s2) • IMS architecture and capabilities (s2) • Issues related to reuse of IMS for NGN (s3-s4) • Support of PSTN/ISDN service emulation (s5) • Ongoing activities and Workplan (s5) • Future cooperation/interactions (s6) • Wrap-up and closure (s6) TISPAN-3GPP Workshop - Sophia-Antipolis

  3. Fundamentals • Advanced Multimedia Services • converged fixed/mobile services • based on 3GPP IMS • Fixed Line Access • Support for PSTN/ISDN Replacement • existing customers unaffected • Extensible • for future services TISPAN-3GPP Workshop - Sophia-Antipolis

  4. Services • ALL 3GPP IMS Services • Plus • Emergency calling (112 etc.) • for all terminals/users • Existing PSTN/ISDN services • for legacy only • Interoperability with 3GPP IMS • Interworking to PSTN/ISDN • both TDM and replacement scenario • Future Services e.g. streaming (RTSP) • e.g. Video on Demand, broadcast services TISPAN-3GPP Workshop - Sophia-Antipolis

  5. System Overview Customer Terminals and Network Access Network Core Network Interconnect TISPAN-3GPP Workshop - Sophia-Antipolis

  6. System Components • Customer Networks & Terminals • Diverse Customer Networks supporting multiple diverse terminals • “shared terminal use” as well as exclusive • Access Networks • re-using existing deployments • xDS,LWireless Lan, Corporate Lan, cable networks, 3GPP GPRS • Core Network • IP Based transport network + IMS • Interconnect TISPAN-3GPP Workshop - Sophia-Antipolis

  7. Constraints • Existing Customer Networks • Hubs, Routers, WLAN • Existing Customer Terminals • PC’s; PDA’s; Phones; • lack of regulation & diversity • Access Networks already deployed • xDSL, backhaul to ISP’s; V5 fibre • Concentrators, multiplexors • Core Network • 3GPP IMS based, minimal changes • Interconnect • other NGN; 3GPP IMS; Internet; PSTN/ISDN TISPAN-3GPP Workshop - Sophia-Antipolis

  8. Requirements Overview 1 • All 3GPP IMS services; • extended/adapted for fixed-line terminals; • Conversational and non conversational services; • Support for existing PSTN/ISDN terminals; • partial or wholesale replacement of existing core infrastructure; • Regulatory Requirements • e.g. Emergency calling from any access; • Interworking at the NNI; • Mobility: nomadicity of users and devices; TISPAN-3GPP Workshop - Sophia-Antipolis

  9. Requirements Overview 2 • Secure and trustworthy environment; • Support for a wide range of QoS-enabled services; • Managed network • high availability; • Flexible framework • service innovation & standardisation minimal; • Third party service provider support; • Flexibility • to support an ever-increasing variety of terminals with diverse capabilities. TISPAN-3GPP Workshop - Sophia-Antipolis

  10. Mobility • User Mobility • Moving to different physical locations and using a terminal • Requires unique identity • Terminal Mobility • the ability to move to different physical locations and provide the user with their services • Authentication • User Authentication (by core) for services • Identification of user • Terminal Authentication (by access network) for connectivity • Device capabilities TISPAN-3GPP Workshop - Sophia-Antipolis

  11. PSTN/ISDN Replacement • Supporting Existing Customers and Equipment • including existing access • Maximum common equipment • PSTN/ISDN Services ONLY • But interoperable with IMS (voice) services • Interconnect to existing (TDM-based) PSTN/ISDN • for all NGN customers (voice only) TISPAN-3GPP Workshop - Sophia-Antipolis

  12. PSTN/ISDN Service Re-use (PSTN/ISDN Simulation) • NGN Customers • Existing (similar) services • divert, voice mailbox, “CLI” etc. • Not Identical to PSTN • Different invocation/ergonomics • To take advantage of new network and terminal capabilities • True PSTN/ISDN Services • Not available, but interworked. TISPAN-3GPP Workshop - Sophia-Antipolis

  13. Services & Requirements • Service Sets • IP Multimedia Services (from 3GPP IMS) • PSTN/ISDN Emulation • Streaming Services • Other Multimedia Services • Requirements • Network Attachment & Authentication • Resource Control • Transport • Interconnect TISPAN-3GPP Workshop - Sophia-Antipolis

  14. Design Issues • Multiple Access Technologies • Mobility & Roaming, & Nomadicity • Numbering & Addressing • Quality of Service (QoS) • Emergency Telephone Services (ETS) • Lawful Interception • Security / Privacy • Routing / Path Determination • Service Capabilities….
