8. Q.CRBT, CRT Standardization in ITU-T
CRBT and CRT will be promising services in NGN
ITU-T SG11 is good place to have well-defined service standardization
There are active participations from CJK
The two documents (Q.CRBT and Q.CRT) are expected to be completed and asked for consent in the next January meeting
We hope CJK cooperation and thank you for the cooperation !

9. NGN Protocol Set
SG11 produced a significant number of NGN Protocol Set 1 related Recommendations. These Recommendations constitute a major reference to enable actual NGN (Release 1) implementations. Various Supplements have been published to document the corresponding NGN.
NGN Protocol Set 2 and more should continue to be developed during the forthcoming Study Period ( ) based on the feedback from first NGN release implementations and new requirements.
To support the NGN Release 2 architecture, the scope of NGN Protocol Set 2 will include signalling requirements and protocols for:
− IPTV and content delivery services
− Mobility management control and mobile application services
− Converged Web and application services
− Multicast data services

10. New Work Items for Q.2, Q.3/11
Signaling requirements/protocols for new value-added converged services in NGN
- Web based application/service support functions: service registration, discovery, service composition, and service orchestration
Enhancements to the existing signalling Recommendations to accommodate emerging technologies such as Distributed network technology (GRID & Peer to peer), Multicast technology (IPTV) etc.
Enhancements to the existing signalling Recommendations to accommodate Private and enterprise networks
Signaling requirements/protocols for IPTV, mobile application services, and sensor network services
Also, it is important to have
Signaling requirements/protocols for Home Gateway control
Transport control protocol for seamless access mobility
Signaling requirements/protocols for NGN number portability
Signaling requirements for session mobility

11. Summary
SG11(Q.2 andQ.3) develops signaling requirement for application services, which is a keen market-driven area
Q.2,3/11 have done good job during current study period
8 Recommendations completed, and 9 work items on going
In new study period, the work of Q2,3/11 will be aligned with the scope of SG13 including IPTV, mobility, USN, P2P etc.
CJK cooperation will be essential !
* NGN release 2 architecture
extended to have mobility and IPTV
