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

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.

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
4
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
5
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
