  1. NGN – Next Steps Brian Moore Chae-Sub Lee Submission Date:July 1, 2008

  2. Highlight of Current Activities • ITU-T has finished the following areas of NGN for Release 1: • Service Requirements and Functional Architecture (FRA 1) • NACF 1 and RACF 1 • MMR/MMF and FMC Requirements • NGN Security Framework • ITU-T is now working on Release 2 in areas of: • Service Requirements and FRA 2 • NACF 2 and RACF 2 • Multicast Requirement and Functional Architecture • Mobility Framework Architecture • Open-Service, Idservice Requirement and Architecture

  3. Strategic Direction • Extending NGN: Services and Capabilities inc. use of WEB • Further application of NGN Standards to support various services • Study to incorporate available convergences: FMC, IPTV and ITS, USN, Networked Robotics and others NextVisionofNGNfromITU-T SG13(NGNleadSG)

  4. Challenges • Investigation of extending NGN: Services and Capabilities • ITU-T NGN R1 ~ Nomadism, R2 ~ Handover/Streaming, then what else beyond R2? • How to use WEB capabilities in NGN? • ITU-T published Recs. on IPv6 based NGN (Y.2051 ~ Y.2054 ), then what is next? • Detailed work on NGN Standards to support various services • How to use NGN for: VoNGN, Conf. over NGN, Web over NGN • What details STD provide to the users? • Study to incorporate available convergences • Internal convergences • FMC (MM/Handover capabilities) • IPTV (Content Distribution Functions) • External convergences • USN • Telematics/ITS • Others (e.g. Networked Robotics)

  5. Next Steps/Actions • It is expected that the ITU-T will have a new structure for studying NGN in the next study period – to be agreed at WTSA-08 • More efficient platform will built to strengthen ITU-T NGN • Common platform which has been achieved by NGN-GSI will continue • NGN study should incorporate with IPTV, USN, IdM and ITS requirements and functions • It is anticipated that more stress will be placed on ITU-T NGN recommendations will meet the end user ambitions and service/network providers business plans • Futuristic vision of NGN including beyond NGN will be developed in collaboration with other SDOs

  6. Proposed Resolution Update • Considering: • that NGN must interwork with and allow a migration path from existing networks and services; • that offering end-to-end multimedia services, including mobility support and IPTV, requires interconnection across different NGN implementations capable of supporting satisfactory security and end-to-end Quality of Service (QoS) and Quality of Experience (QoE); • that NGN has a significant role as an infrastructure supporting there is a need to achieve interworking among different networks, including (mobile and fixed)interworking, and multimedia services including convergence servicesbetween NGNs on the basis of a minimum number of globally agreed protocol profiles; • that there is increasing demand for converged services with ubiquitous capabilities allowing users to obtain access to their services and profiles using any appropriate devices independent of the means of access (fixed, mobile, etc.); • that there is increasing deployment of broadband access capabilities, both fixed and wireless, capable of supporting advanced services envisaged for NGN; • that NGN is being introduced within an evolving policy and regulatory environment; • that there is a need to further globalize NGN standardization; • that there is a need to develop NGN standards in a timely manner; and • that the 3GPP Organizational Partners have confirmed their support for the proposal to develop global Common IMS specifications within 3GPP. See ITU-T Q.1761 (approved) and Q.1762/Y.2802 (under AAP.)

  7. Proposed Resolution Update • Resolves: • 2) to promote globally consistent standards through cooperation and collaboration among global, regional and national SDOs on NGN issues that have mutual impacts, including (but not limited to) the following: • interconnection and interoperability across mobile and fixed networks offering convergence multimedia services, including the ability to obtain services independent of underlying transport access or network e.g., based on a unique, global SIP profile; • enabling of migration from legacy networks towards NGN; • interconnection and interoperability of networks offering multimedia services, e.g., based on a unique, global SIP profile; • evolution of IMS as a solution to suit the needs of both mobile and fixed networks; • evolution of Call Server based approach as a solution to suit the needs of fixed networks; • maximization of the commonality and interworking between different approaches; • recognition of potential social, policy, legal, emergency, and/or regulatory implications (for example, privacy, legal interception, location information, service quality, reference interconnection point definition); • options for transition, and planning considerations for achieving the NGN vision in an orderly and consistent manner; • control and realization of Quality of Service (QoS)/Quality of Experience (QoE) mechanisms for all types of networks (fixed, wireless, mobile, satellite, IP-based core networks, etc.) capable of interoperating to deliver satisfactory end to end QoS/QoE; • interoperable and cost-effective security mechanisms and protocols to guarantee protection of customer information and network resource; • user mobility in all its forms (wide area, local area, nomadic, etc.), including seamless mobility across mobile and fixed networks;

  9. NGN ManagementDave SidorChairman of ITU-T Study Group 4

  10. Highlight of Current Activities • SG 4 • Approved several B2B/C2B NGN management Recommendations • Terminated the NGN Management Focus Group (NGNMFG) • Established the Joint Coordination Activity on Management (JCA-Mgt) • NGN Management Focus Group • Produced a restructured NGN Management Specification Roadmap (v5.1) • Served as a facilitator of management specification harmonization and gap analysis

  11. Strategic Direction • To foster greater industry collaboration in the development of management specifications to support telecom services, networks, and equipment with an emphasis on support for NGN

  12. Challenges • The plethora of SDO and forum management specifications to support NGN and other network technologies • SDO and forum willingness to support “one industry solution for one industry problem” • The convergence of telecom and IT technologies and associated management solutions

  13. Next Steps/Actions • To obtain industry support for the Joint Coordination Activity on Management (JCA-Mgt) which will • Cover the management needs of NGN as well as the next generation of telecom management networks and systems • Focus on specifications related to management interfaces between network elements and management systems and between management systems • Serve as a focal point for sharing interface work plans and deliverables among SDOs and fora • Act as a facilitator of management specification harmonization and gap analysis

  14. Signalling Requirements and ProtocolsYukio HiramatsuChairman of ITU-T Study Group 11

  15. Completion of NGN Protocol Set 1 PS1 constitute a fundamental basis for initial implementations of NGN Release 1 • Signalling architecture for the NGN Service Control Plane in co-ordination with SG13 NGN architecture questions (Q.3030) • Signalling requirements at (SUP-FE) - (I/S-CSC-FE) i/f (Q.Sup.54) • Signalling requirements at (AS-FE) – (S-CSC-FE) i/f (Q.Sup.55) • Organisation of NGN Service User Data (Q.Sup.56) • Signalling requirements and ISUP and BICC signalling protocol extensions for the support of IEPS communications (Q.Sup.57 and Amendments to ISUP, BICC and DSS2 protocols) • NGN NNI and UNI signalling profiles (Q.3401 and Q.3402) • Interface control protocols for RACF (Q.3300-series) • Rs, Rp, Rc, and (PD-PE) – (PE-PE) interface

  16. Completion of NGN Protocol Set 1 • Interworking between ATM and IP-based networks (Y.1416/Q.3150 and Y.1417/Q.3151) • NGN testing for the support of the compatibility of NGN technical equipment and services (Q.3900, Q.3901 and Q.3902) • Work was progressed in cooperation with ITU-D for development of a handbook for deployment of packet based networks (a Q.Sup. expected at the next SG11) • Network Attachment Control Signalling Requirements and Protocols. • EAP-based security signalling protocol architecture (Q.3201)Note – EAP: Extensible Authentication Protocol • Authentication protocols for interworking among 3GPP, WiMax and WLAN in NGN (Q.3202.1)

  17. Strategic Direction • Lead study group activities on Intelligent Networks (IN) • Recommendations produced in previous Study Periods are considered stable no changes are foreseen at this time. There were no activities in this Study Period. • Lead study group activities on Signalling Requirements and Protocols • SG11 produced a significant number of NGN Protocol Set 1 related recommendations. These Recommendations constitute a major reference to enable actual NGN (Release 1) implementations. Various Supplements have been published to document the corresponding NGN Signalling requirements. • NGN Protocol Set 2and more should continue to be developed during the forthcoming Study Period (2009-2012) based on the feedback from first NGN release implementations and new requirements.

  18. Challenges • SG11 needs to continue its work to define signalling requirements and protocols • for smooth evolution from conventional PSTN/ISDN towards future NGN, which will take long time. • ITU-T should continue to lead signalling and protocols work • to ensure harmonized global signalling standards and avoid interworking and interoperability problems in the worldwide telecoms networks. • considering that ITU-T is the unique global place where the worldwide industry and governments work together in defining international telecommunication networks and services. • SG11 needs to cooperate with outside standardization bodiessuch as IETF and 3GPP • to effectively develop necessary protocols based on the market needs and also to avoid duplication of work among different bodies.

  19. Next Steps/Actions • All Questions require continuation in order to address various additional features and consider initiating work in the scope of an NGN Protocol Set 2 (e.g., IMS, IPTV, WiMAX, RFID). • Signalling architecture and requirements. • Session control requiring further work on SIP-based profiles to improve interoperability at UNI and at NNI, as well as for supporting more services and applications; • Bearer control for support of IPTV and multicast data delivery services, for support of more efficient transfer capabilities such as flow state aware transfer capability; • Resource control for developing additional interfaces protocols fitting with the RACF enhanced architecture, as well as supporting IPTV, mobility, E2E QoS coordination, PCN/PCE application etc.Note – PCN: Pre-congestion Notification. • NGN network attachment and identification, signalling protocols to support Emergency Telecommunications Service (ETS) and Telecommunications Disaster Relief (TDR) and early warning systems as well as NGN testing and security.
