Future Work (I)
All Questions require continuation in order to
address various additional features and consider
initiating work in the scope of an NGN Protocol
Set 2 (e.g., IMS, IPTV, WiMAX, RFID).

–
Signalling architecture and requirements.
Session control requiring further work on SIP-based
profiles to improve interoperability at UNI and at NNI, as
well as for supporting more services and applications;
Bearer control for support of IPTV and multicast data
delivery services, for support of more efficient transfer
capabilities such as flow state aware transfer capability;
Resource control for developing additional interface
protocols fitting with the RACF enhanced architecture.
Coordination with regional SDOs including development
of a handbook to assist ITU-T members in the
deployment of packet-based networks to support
PSTN/ISDN services

Future Work (II)
–
NGN network attachment and identification for support
of a wider range of access technologies and mobility
management requirements.
Some new Questions are required to accelerate
study on:
–
–
–
–
–
–
Monitoring parameters for NGN protocols
Service test specification for NGN
QoS tests specification for NGN
USN and RFID test specification
Coordination of work on Emergency Communications
within an NGN environment
Security Coordination For NGN Protocols

Conclusion
SG11 produced a significant number of NGN
Protocol Set 1 related Recommendations during
the current study period. These
Recommendations constitute a major reference
to enable actual NGN implementations
(Release 1). Various Supplements have been
published to document the corresponding NGN
Signalling requirements.
NGN Protocol Set 2 and more should continue
to be developed during the forthcoming Study
Period (2009-2012) based on the new
requirements and feedback from first NGN
release implementations.

Thank you!
Yukio Hiramatsu is Professor, Graduate School of
Intellectual Property, Osaka Institute of Technology. He
was with NTT from 1978 to 2005. Active in the ITU-T
since 1985, he has been serving as Chairman of Study
Group 11 (Signalling requirements and protocols)
since October 2000. Prior to this position, he served in
Study Group 7 (Data communications and OSI) from
1996 to 2000 as Vice-Chairman of the Study Group
and Chairman of Working Party 2/7 dealing with
network interfaces. Among his major achievements
are completed BICC Recommendations already
adopted by the 3GPPs and the ongoing signalling
protocol work for the NGN (Next Generation
Networks).
