  1. FORUM ON NEXT GENERATION STANDARDIZATION (Colombo, Sri Lanka, 7-10 April 2009) An Implementable NGN Architecture, and its Capabilities Session Moderator Ghassem Koleyni

  2. Presentations and presenters • Session 4P1: Technical challenges in building the NGN - NTT’s activities (Mr. Tatsuro Murakami, NTT, Japan) • Session 4 P2: Requirements and capabilities for an evolving NGN infrastructure (Mr. Marco Carugi, Nortel, France) • Session 4 P3: An implementable NGN architecture and its capabilities (Mr. Tilak De Silva, Sri Lanka Telecom, Sri Lanka) • Session 4 P4: Access networks for NGN implementations (Mr. Bharat Bhatia, Motorola, India) • Session 4 P5: Converged Service Network (Mr. Mingdong Li, ZTE, China)

  3. Session 4 objectives • Discussion on the standards-based, implementable NGN architecture considering • Overall functional architecture of an implementable NGN architecture • Functional architecture for supporting mobility and realization of FMC environments • Architectural view points of “Quality of Services” and “Network Performance” to meet NGN service requirements from users and providers • Relevance of IPV6 for NGN transportation • NGN Access Networks

  4. Highlights and proposals from Presentation 1 Technical challenges in building the NGN - NTT’s activities • NTT has been experimentally investigating VoIP using SIP for a long time. • Selected SIP to promote broadband services. • Mandated to have low interconnection charge LLU (Local Loop Unbundling) • Selected overlay to create a new service structure and increase ARPU • NTT believes that NGN brings both Network Innovation and service innovation. • Phasing out PSTN after 2010

  5. Highlights and proposals from Presentation 2 Requirements and capabilities for an evolving NGN infrastructure • IMS as central component in NGN • Key architectural challenges • Application-driven QoS • Mobility • Scalability • Mobility: a fundamental enabler of NGN • The multiple dimensions of convergence • Convergence of services, service platform, networks, devices, management • Interoperable Identity Management solutions are required • Connectivity-oriented vs Service-oriented Interconnect • Both will co-exist, addressing different markets

  6. Highlights and proposals from Presentation 3An implementable NGN architecture and its capabilities • Today’s network vertically integrated: • TDM Tx Back Bone (PSTN / ISDN, TDM Data network, CDMA Network), IP / MPLS Back Bone, Metro Ethernet Network • Future network (i.e. NGN) • IP / MPLS Back Bone (NGN /IMS), TDM Tx Network (CDMA Network) • Reasons for migration • End of life cycle, end of signaling support for R2, customer demand for new features • Why going to NGN? • High system capabilities (Call handling, subscriber capacity, traffic handling, etc…..) • Availability of new services. (Unified messaging, IP Centrex/Hosted PBX, etc…) • More cost effective (i.e. Less CAPEX) • Step-by-step approach to ALL IP & FMC • TDM → ALL IP; ALL IP + Voice (soft switch); ALL IP + Multimedia (IMS); ALL IP + FMC

  7. Highlights and proposals from Presentation 4 Access networks for NGN implementations • Today: Access Network  Device  Service  Application • Tomorrow: The NGN access technologies Providing all IP transport • India is going wireless with subscribers increasing at the rate of 10-15 Million per month • WiMAX & LTE Makes On-Demand Possible • WiMAX & LTE provide Faster, more responsive, lower cost, added capacity, flexible and global accessibility • WiMAX & LTE are Accelerating the delivery of media experiences (Broadband everywhere, Optimized networks, Content to the consumer)

  8. Highlights and proposals from Presentation 5 Converged Service Network • Current situation of service ecosystem • Integration of the value chain • Decrease of revenue from consumers and enterprises • High CAPEX/OPEX • Issues related to charging • Trends in service evolution • Mobility across fixed and mobile networks • Convergence (Terminal, network, service, resource aggregation) • UGC and UGS • Next generation service creation environment • Key issues • Identity Management (Global ID) • Service, Capability, Resource Addressing • Open service framework • Intelligent Policy decision and network adaption • Data mining

  9. Conclusions / Recommendations • Majority of current networks are vertically integrated. This needs to be changed. • NTT has decided to phase out PSTN by 2010 and moving to NGN • Application-driven QoS , mobility and scalability are major challenges which need attention in evolving the NGN • Convergence is needed for services, service platforms, networks, devices and management services • WiMAX & LTE provide Faster, more responsive, lower cost, added capacity, flexible and global accessibility • Some key issues for convergence service framework need to be addressed in standardization
