Terms of Reference

• Responsible for studies relating to signalling
  requirements and protocols for Internet protocol
  (IP) related functions, some mobility related
  functions, multimedia functions for networks
  including convergence toward NGN, and
  enhancements to existing Recommendations on
  access and internetwork signalling protocols of
  BICC, ATM, N-ISDN and PSTN.
• Lead SG for
• signalling and protocols
• intelligent networks

4
Highlights of achievements (I)

• SG 11 has completed NGN Protocol Set 1 which
  constitute a fundamental basis for initial
  implementations of NGN Release 1
• Signalling architecture for the NGN Service
  Control Plane (Q.3030)
• Signalling requirements at (SUP-FE) -
  (I/S-CSC-FE) i/f (Q.Sup.54)
• Signalling requirements at (AS-FE) (S-CSC-FE)
  i/f (Q.Sup.55)

5
Highlights of achievements (II)

• Organisation of NGN Service User Data (Q.Sup.56)
• Signalling requirements to support the emergency
  telecommunications service (ETS) in IP networks
  and protocol extensions for the support of IEPS
  communications (Q.Sup.57 and Amendments to ISUP,
  BICC and DSS2 protocols)
• NGN NNI and UNI signalling profiles (Q.3401 and
  Q.3402)

6
Highlights of achievements (III)

• Interface control protocols for RACF
  (Q.3300-series)
• Rs, Rp, Rc, and (PD-PE) (PE-PE) interface
• Interworking between ATM and IP-based networks
  (Q.3150/Y.1416 and Q.3151/Y.1417)
• NGN testing for the support of the compatibility
  of NGN technical equipment and services (Q.3900,
  Q.3901 and Q.3902)

7
Highlights of achievements (IV)

• Work was progressed in cooperation with ITU-D for
  development of a handbook for deployment of
  packet based networks (a Q.Sup. expected at the
  next SG11)
• Network Attachment Control Signalling
  Requirements and Protocols.
• EAP-based security signalling protocol
  architecture (Q.3201)Note EAP Extensible
  Authentication Protocol
• Authentication protocols for interworking among
  3GPP, WiMax and WLAN in NGN (Q.3202.1)

8
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

9
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

10
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).
