  17. TISPAN_NGN Release 2

  18. Synchronisation of Specifications with 3GPP • Alignment of the timescales and dependencies of TISPAN R1 with the work in 3GPP Release 7 on FBI. • Alignment of the timescales of TISPAN R2 with the ongoing work in 3GPP Release 8 and FMC. • Objective: Single core solution based on: • IMS Core signalling technology • Multiple access technologies in cooperation with 3GPP • ADSL • WLAN via xSDL • 3GPP CAN (GPRS, WLAN via GPRS, etc..). • Ongoing discussions within TISPAN, 3GPP and other SDOs and groups.

  19. Services and Features (1/2) • TISPAN is progressing the work on R2 concerning the following main new work items: • Requirements analysis for FMC. • Requirements analysis for home networking (in cooperation with e.g. HGI).   • Requirements for network capabilities to support IPTV services (in cooperation with e.g. ATIS IIF and DVB). • IPTV Integration of NGN Services and Capabilities using IMS • Support of Business Services and Enterprise Network inter-working. • Close and direct co-operation with Ecma International on • NGN Business services and Enterprise capabilities. • NGCN – NGCorporateN interconnect requirements.

  20. Services and Features (2/2) • According to the TISPAN enhancements for R2 and beyond; new requirements in the NGN R2 definition were raised, on requirements analysis for work that needs to be shared with other bodies. • Requirements for originating and terminating party multimedia information presentation and restriction. • Additional Features for Enhanced Communication Diversion  (these features are still under discussion) • Service Requirements and Network Capabilities for Release 2.  • Release 2 Definition.

  21. FMC – Fixed Mobile Convergence • A work-item on requirements collection has been started • Collection of about 10 use cases regarding FMC • The Use Cases are only there to derive and analyse requirements • The objective of the WI is to identify (high level) requirements • This includes identifying in which SDO's / body's / group's have the scope that the requirements exist • TISPAN wishes to co-operate on FMC; i.e. based on a common set of requirements • To agree an appropriate distribution of work.

  22. Release 2 - ArchitectureNew Functionalities (in progress) • Evolution of RACS • Resource control in the core • Towards End-to-end QoS • Evolution of NASS • Additional access technologies • Fixed access via xDSL (e.g. ADSL) • wLAN via xDSL (e.g. IEEE802.11) • WiMAX etc.. • IPTV support • Online Charging • Overload control (GOCAP)

  23. Overview of New WorkNumbering, Naming, Addressing, Routeing • Active discussions with GSMA IREG (Interworking Roaming Expert Group) • Infrastructure ENUM • GSMA IPX backbone (IP eXchange – next generation of GPRS Roaming Exchange) • Identification of key management and operational issues to be considered for a shared approach to be viable • It is expected that key interconnect issues will also come to the fore. • Objective: to specify a Single global solution for NGN

  24. Overview on New WorkSecurity, Testing, Network Management • Security • Joint meeting with 3GPP SA3 on authentication and NAT/FW (network address translation, firewall) transversal issues. • Authentication to NASS and to IMS services • Testing • Conformance to TISPAN, 3GPP, ITU-T standardised protocols • Global interoperability of PES and Core IMS NGN R1 • Network Management • Service Oriented Architecture (SOA) • NGN OSS (Operation Support System) Service interfaces in line with NGN OSS architecture. • Common information model TISPAN MIM • Subscription Management • Network Resource Management • Network resource management based on 3GPP model both reuse + new TISPAN-specific entities

  25. QoS • The TISPAN System Group will have overall control of QoS issues within TISPAN and will coordinate and allocate work to the Working Groups as necessary. • TISPAN and STQ will work in close co-operation. • STQ works on what we want to achieve in terms of parameters and numbers • User-to-user and application layer QoS requirements • The network performance required to support these requirements • TISPAN works on how we achieve this in terms of design • Functional and architectural requirements • Signalling and protocols to be implemented • Co-operation with other bodies as well, e.g. ITU-T, IETF etc., see also “External Relations” at the beginning of the presentation.

  26. Security Considerations • Regarding security, focus on requirements covering the following considerations: • Security • Network security • User security • Security management • Regulatory aspects • Lawful Interception • Data privacy • Data retention • TISPAN WG7 are to make recommendations on Services features, architectures, and protocols

  27. Home Devices and Home Networking • The Terms of Reference for TISPAN have been enhanced to include home devices and home networking issues, considering layer 2 and higher layers. • Regarding the layer 2 issues, TISPAN will have the ownership of the layer 2 related to the NGN home devices and networks and will closely coordinate with TC AT/TM. AT/TM will keep the ownership of layer 1.

  28. Summary

  29. Summary • Thanks to all TISPAN collaborators and officials! • Identification of the right issues in order to cover the market needs. • Provision of high quality and implementable deliverables. • Maxim: To Achieve Maximum Co-operation and Communication, Internally andExternally. • Globalisation of our results.
