Global Standards Collaboration (GSC)
GSC-15
Highlight of Current Activities (1)

The standardization activities on NGN in CCSA are progressing smoothly. Except
referring to the relevant specifications or drafts issued by international SDOs,
CCSA also works on building some specifications based on requirements from
China market.

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
• Improve the specifications related to “Unified IMS”
• Develop the specifications related to “Ubiquitous Network”
• N-ID, IDM aspect
• Future Network
• etc.
5
Strategic Direction(2)
 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 give contributions

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 emerge 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
Next Steps/Actions
 Continue to develop NGN-related specifications
• Unified IMS, API, UC, IDM, EC, ICT, 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, etc.
 Continue to work cooperatively with external
organizations
