Standardization activities on NGN in CCSA
CCSA
Submission Date: July 1, 2008

2. Highlight of Current Activities (1)
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

3. 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
