Standardization activities on NGN
in CCSA

Geneva, 13-16 July 2009
Fostering worldwide interoperability
Highlight of Current Activities (1)
The standardization activities on NGN in CCSA are progressing smoothly.
Besides referring to the relevant specifications or drafts issued by
international SDOs, CCSA also works on building some specifications
based on requirements from China market.
Recently works:
Unified IMS aspect
Protocols: SIP specifications in IMS(YD/T, Working on)
Services:
CRT, CRBT, IP Centrex, CW, MCID, ACR (6 YD/T, completed)
Click to Dial, Multimedia Conference(YD/T, Working on)
Test specifications of SIMPLE IM, PoC, Presence, XDM(4 YD/T,
Working on)
Equipments: P-CSCF,I/S-CSCF,HSS,SBC(YD/T, Working on))
Interworking: SIP&BICC interworking, IMS interworks between
different operators, IMS interworks with softswitch network (3
YD/T, Working on),

• Recently works: (Con.)
– API aspect
• Personal Application based on Parlay X API (YDB, completed)
• Enterprise Application based on Parlay X API (YDB, ,completed)
• Test Methods of Parlay Gateway(YD/T, completed)
– Unified Communication
• Requirements of UC services(YD/T, completed)
• Research of UC technologies and standardization requirements(research report,
completed)
• Interface Technical Requirement of Instant Message and Voice Communication
Service for UC（YD/T, working on）
– IDM
• IDM research in NGN (research report, completed)

Fostering worldwide interoperability
Highlight of Current Activities (2)
• Recently works: (Con.)
– Security
• Security framework of NGN (TR, completed)
• security requirements of softswitch equipments (Serial YD/T, completed)
• Security requirements of Unified IMS (TR, working on)
– others
• FMC service requirement analysis(research report, completed)
• Capabilities and requirements of Enterprise network connecting to NGN(TR,
working on)
• NGN based IPTV(research report, completed)
• Mobility research in NGN (research report, working on)
• Working closely with other SDOs. CCSA not only refers to the
achievement of other SDO’s Standardization, but also presents lots of
contributions to SDOs, such as ITU-T, 3GPP, 3GPP2,OMA,DSL Forum,
etc, based on technical research and developed specifications

Fostering worldwide interoperability
Strategic Direction
Continue to develop specifications of NGN in CCSA
While “Convergence” has been a marked trend, CCSA will
pay attention to its influence on current and new
specifications, not only FMC, but also the convergence of
telecom network and internet, the convergence of legacy
telecom services with content-based services, and so on.
Develop and motivate the research in new technical
domains
UC(Unified Communications)related specifications have and
are going on
“M2M” or “Ubiquitous Network ” related specifications are
under consideration
Combination of “P2P” and “NGN”
N-ID, IDM aspect, etc.
5
Fostering worldwide interoperability
Strategic Direction (Con.)
Research on new solutions, such as PTDN,
Future internet.
Develop specifications related to EC, security
protection, and ICT(Energy Saver and Exhaust
Reducer ) in NGN scope
Continue coordination and collaboration, take
part in the relevant activities and meetings,
establish smooth relationship with other SDOs
Share CCSA view
Being involved and delivering contributions
6
Fostering worldwide interoperability
Challenges
Convergence of different networks, applications&services, etc.
Ubiquitous services Requirements of users, span over different
terminals, different access technologies, different networks,
different industries, etc. The scope of NGN is being enlarged.
Mobility Management
Service assurance
QoS assurance
Security, etc.
New techniques emerging over time, and their combination
with NGN, （e.g. P2P, Grid, Mash UP, Widget.） need to be
considered
Information processing-related capabilities are becoming
important, and has introduce many challenges on developing
relevant standardizations
Social responsibilities
Environment
Disable people
Emergency communication
and security, etc
7
Fostering worldwide interoperability
Next Steps/Actions
Continue to develop NGN-related specifications
Unified IMS, API, UC, IDM, EC, security, Home Network, etc.
Initiate some new research items , based on
new trends and new technique, some HISs are
probably as following:
NID/IDM
IMS based P2P application
Framework of future network
Ubiquitous Network
service Network aspect research
Split of identifier and location
Architecture or realization of UC, etc.
Continue to work cooperatively with external
organizations
