Additional supplementary services (about 400 test cases) would be done by a new STF planed for The Abstract Test Suites will be compliant to RFC 3261 and ETSI ES (modified 3GPP TS ).
GSC: Standardization Advancing Global Communications Synchronisation with 3GPP Synchronisation of TISPAN R2 with the ongoing work in 3GPP (e.g. R7, FMC). Objective: Single core solution. Ongoing discussions within TISPAN, 3GPP and SDOs.
GSC: Standardization Advancing Global Communications External Relations (1/3) TISPAN considers co-operation with external bodies and organisations as essential. TISPAN is providing input and considering feedback. External bodies and organisations are showing great interest in working together with TISPAN as a place to come for implementable NGN specifications. –For example, TISPAN have active delegations from China, Japan, North America, South America. –Per meeting, TISPAN are attracting about 150 delegates and handling over 250 documents. TISPAN is looking forward to any enhanced or new co-operation, any organisation or body that wishes to co-operate with TISPAN is most welcome. Coordination of a global message.

GSC: Standardization Advancing Global Communications Protocols
GSC: Standardization Advancing Global Communications 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, 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 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 QoS
GSC: Standardization Advancing Global Communications 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 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 Network Management
GSC: Standardization Advancing Global Communications 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
