• At NGN core network aspect, Up to now, CCSA has nearly completed specifications related to 3GPP R6, now it’s working on the specifications based on 3GPP R7 & R8,and TISPAN R1&R2, ITU-T R1&R2– Currently CCSA has started to focus on Phase 3 of unified

IMS(equipment specification; Protocol & etc.)• Recently work:

– Unified IMS aspect• Terminal: some terminal specifications related to services• Requirements and architecture: three specifications have just completed• Protocols: just initiated SIP specifications in IMS• Services: Presence/PoC/Identification Presentation and Restriction/Call

forwarding/IP Centrex/PES&PSS&multimedia requirements have been completed

• Equipments-CSCF,I/S-CSCF,HSS of unified IMS just initiated• Interworking: SIP&BICC interworking, IMS interworks with other network

between different operators

Highlight of Current Activities (2)• Recently completed work: (Con.)

– Transport control aspect• NASS: one YDC has completed• RACS: one TR has completed

– Security aspect• UNI&NNI security requirement have been completed• One TR started: Unified IMS security requirements

– NGN based IPTV aspect• IMS based IPTV&Non-IMS based IPTV: One TR is progressing• Note: lots of non NGN-based IPTV have been completed or ongoing

– Home Network aspect• 13 documents are completed, including Home Network General requirements,

Home Network Gateway

• Working closely with other SDOs. Based on technical research and developed specifications, CCSA or members of CCSA have presented lots of contribution to SDOs, such as ITU-T, 3GPP, 3GPP2, OMA, DSL Forum, etc.

4

Strategic Direction

• Continue to develop technical and test specifications of NGN in CCSA– Recently initiated five new specifications of unified IMS– other specifications may be initiated later– Based on the newest specification in the worldwide

• Develop and motivate the research in new technical domain– three UC(Unified Communications) documents have been initiated– Other topic are being considered

• Continue coordination and collaboration, take part in the relevant activities and meetings, establish smooth relationship with other SDOs– Share CCSA view – Being involved and give contributions

5

Challenges• Convergence of telecommunication and internet

– Convergence of IMS and Web services– Service creation, management, service delivery platform, etc.

• Convergence of Multimedia and streaming Media– Interworking with legacy IPTV

• Interoperation and interworking with different PAN or LAN– Capabilities supporting Home network and Business network– Capabilities supporting the requirement of information society

• Capability to support wireless and wired technical– Mobility and Nomadic– Access control– Location, etc

• Unified user Data– integrity of data distributed in versatile applications

• Application of P2P technology in telecommunication network

6

Next Steps/Actions• Complete the series of NGN specification

– Such as Protocols, Service, equipment, etc– Including technical specification and test specification

• Keep up with new technique and new requirements, the relevant other HIS are probably as following:– FMC– UN(Ubiquitous Network)– UC(Unified communication) or ICT– IDM– P2P application in NGN– Service or service capabilities convergence of internet and

telecommunication

• Continue to work cooperatively with external organizations
