Release 2 New Functionalities (in progress) • Evolution of RACS • Resource control in the core • Towards End-to-end QoS • Evolution of NASS • Additional access technologies beyond DSL • IP-TV support • Online Charging • Overload control (GOCAP) GSC: Standardization Advancing Global Communications

  25. Protocols GSC: Standardization Advancing Global Communications

  26. NGN Stage 3 • NGN Release 1 has developed Protocols and Profiles in the following areas: • NASS: e1, e2, e4, e5, • RACS: Rq, Gq’ • H.248: AWG/RGW, TGW, Congestion Control, BGW, MGW, • PES on IMS • Protocols: NGN IMS SIP, Inter-working of SIP-ISUP, Inter-working @ an IBCF, Inter-working with 3GPP IMS SIP, • Services: CONF, MWI, Hold, ACR-CB, OIP/OIR, TIP/TIR, MCID, XCAP Ut I/f, ECT, Presence, Instant Messaging, • NGN Release 2 will develop protocols and application profiles for: • Service Direct Call, CW, CCBS/CCNR, AoC, • IPTV • FMC GSC: Standardization Advancing Global Communications

  27. NGN cooperation • In the NGN Stage 3 work close cooperation has been essential with the 3GPP CN/CT groups Many of the NGN R1 specifications are either • profiles (a subset of a 3GPP specification) • or endorsements, • occasionally with access specific parts and some additional clauses. • The work on H.248 has cooperated closely with ITU-T SG16, 3GPP CT4, and has cooperated and taken ideas from the MSF. • The work of services and applications relies heavily on cooperation with 3GPP CT1 and the respective IETF Sipping and SIP working Groups. In NGN R1 caused by time limitations the majority of cooperation with the IETF was reliant on features already defined for 3GPP needs. As specific Service Application Protocols are needed in NGN release 2 closer cooperation with certain IETF Working Groups is expected. • Please see also “External Relations” at the beginning of the presentation. GSC: Standardization Advancing Global Communications

  28. QoS GSC: Standardization Advancing Global Communications

  29. Overview • We are currently in the process of re-organising how the work on Performance & QoS of NGNs is allocated in ETSI. • The work areas currently allocated to TISPAN WG5 (QoS) will be split between TC STQ (Speech Processing, Transmission and Quality Aspects)and TISPAN. • There will be no dedicated QoS WG in TISPAN – WG5 has been closed down. • The TISPAN System Group will have overall control of QoS issues within TISPAN and will allocate work to the Working Groups as necessary. • TISPAN and STQ will work in close co-operation. • Co-operation with other bodies as well, e.g. ITU-T, IETF etc., see also “External Relations” at the beginning of the presentation. GSC: Standardization Advancing Global Communications

  30. Principle behind the split • 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. • Many Work Items may require close co-operation. • The details of the allocation of the work areas still need to be formalised. GSC: Standardization Advancing Global Communications

  31. Network Management GSC: Standardization Advancing Global Communications

  32. Network Management • Focus of activities • With respect to TISPAN NGN R2, the main focus will be to • Specify a general Information Model (i.e. MIM – TISPAN Information Model) able to model all relevant TISPAN NGN management entities • Deliver specifications of NGN OSS Service Interfaces as defined in the NGN OSS Architecture and on the basis of the general Information model • Propose, develop and enhance ad-hoc co-operation with other TISPAN WGs as needed GSC: Standardization Advancing Global Communications

  33. TISPAN achievements on Network Management • Release Independent • TR 188 004: OSS Vision • TS 188 003: OSS definition of requirements and priorities for further network management specifications for NGN • TR 102 647: Management Overview and gap analysis • Release 1 • TS 188 001: NGN OSS Architecture Release 1 (version 2) • Main principles and concepts of the TISPAN NGN Architecture have been included and mapped within ITU-T approved Recommendation M.3060 “Principles for the Management of Next Generation Networks” GSC: Standardization Advancing Global Communications

  35. Objectives for Release 2 • Network Resource Model (Requirements, Information Service, Solution Set) • Creation of an information model which captures the management aspects of the TISPAN NGN (i.e. the view of the NGN as exposed to Operations Support Systems (OSS)) • NGN Subscription Management Requirements • Definition of an end-to-end data model to cover all the mandatory/optional information related to subscription management that must be provisioned on the NGN Network • Definition of a subscription management architecture which hides the complexity of the different nodes to be configured including the CPE and the AS • Management Information Model • Design of an information abstraction and representation of the TISPAN entities - their properties, operations, and relationships, independent of any specific repository, application, protocol, or platformThis information model must also provide a linkage between services defined within TISPAN and TISPAN entities.
