  4. Video Services (TV, movie, etc) Data Services (WWW, e-mail, etc) Telephone Services Services API Transport CORE ACCESS ACCESS 1. Why NGN ? Separation btw. Services and Transport • Key Feature of IP : Anything over IP, IP over Everything • Most of Services using IP as their connection platform • Most of Networks supporting transport of IP packet • IP plays a key role to separate Services with Transport

Impacts to Policy and Regulation base • NGN provide a platform separating Services with Transport • Politics and Regulation environment would be impacted with this • Current Vertical environment would be changed to Horizontal env.

  8. 2. NGN Standardization NGN 2004 Project • A new ITU Project on NGN : SG13, Nov. 2002 • Project description document has been prepared(http://www.itu.int/ITU-T/studygroups/com13/ngn2004/index.html ) • Fundamental characteristics for defining NGN • Packet-based transfer • Separation of control functions for bearer - call/session – service • Decoupling of services and network, provision of open I/F • Wide range of services (RT/ streaming/ non-RT/ multimedia) • BB capabilities with e2e transparency, incl.AN utilization • Interworking with legacy networks • Generalized mobility • Unfettered access from users to competing SPs and services

  9. 2. NGN Standardization JRG on NGN • ITU-T SG 13 launched JRG-NGN at 1st August 2003 : 3 Meetings • Joint Special Rapporteur Group Activity within SG 13 • Focus on “Foundational Documentation of NGN” until June. 2004 Draft Recommendations in AAP Deliverables for further study 

  10. 2. NGN Standardization JRG on NGN Deliverables on QoS for further study 

  11. 2. NGN Standardization NGN Focus Group • ITU-T Director launched NGN Focus Group at June 2004 • Almost every two month meeting : 6, 7, 9, 11/2004 and 2, 4, 6/2005 • Functional & Nomadicity Architecture (base on IMS & non-IMS) • QoS (include the xDSL Access) • Security Capability (inc. Authentication) • NGN Control and Signaling Capability • Evolution from CGN to NGN

  12. 2. NGN Standardization NGN Focus Group Deliverables on Service Requirements and Architecture 

  13. 2. NGN Standardization NGN Focus Group Deliverables on Quality of Services 

  14. 2. NGN Standardization NGN Focus Group Deliverables on Signaling, Security, Migration and Future 

  15. Target Standards Area Convergence btw. Fixed & Mobile Generalized Mobility Open Access I/F Unrestricted Access Architecture and Open API Separation Services with Transport QoS-enabled Transport Manageable Broadband Multiple-Broadband 3. Key Features Definition & Features of NGN Definition of NGN (Draft Rec. Y.2001) A NGN is a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It offers unrestricted access by users todifferent service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.

  16. 3. Key Features Functional Architecture Model

  17. 3. Key Features Customer Manageable Capability • Capabilities to support user manageability on IP network. • Users can allocate, configure, control, and manage • the resources of NGN Network elements

  18. CN AN AN CPN CPN 3. Key Features QoS Aspects of NGN General reference configuration for NGN QoS, NP and QoE Man-Machine Interface Network Interface Network Interface Man-Machine Interface User TE TE User Network Performance for NGN QoE QoE Quality of Service for NGN

  19. Mobility Service Service Continuity Discontinuity Seamless Handover Roaming Portability Handover Intra-AN Mobility Inter-AN Mobility Inter-CN Mobility Inter-TE Mobility Inter-TE Mobility 3. Key Features Mobility Aspects of NGN

  20. 3. Key Features Evolution Aspects of NGN • 4 Scenarios for PSTN evolution to NGN 3rd Scenario 4th Scenario

  21. Near GN Next GN Packet based Network Fixed Mobile Conv. Access Packet Based Tele-Broad conv. Network Fixed Mobile Conv. BB Access BB X-casting MM QOS Mobility TDM based Network Broadcasting Net. 4. Future Issues Standards for Near Generation, not Next • NGN stands for Next Generation, but targeted for Near Generation • NGN could be value added framework for all players : Users, Operators, Providers and Regulators etc. • NGN could be evolved from Current Generation Network • NGN could be basement for making convergence world (real Telecommunication World) • NGN Standards could be Globalize rather than Localize boosting global village and shorten digital divide • ITU-T could be centre of NGN standards CGN Packet based Network Mobile Access TDM based Network Fixed Access Broadcasting Net.
