Future Work (I)

• The focus of the ongoing work will be to complete
  the NGN standards programme and to study beyond
  NGN
• Study group 13 has developed 17 new / revised
  questions covering the following areas of
  competence
• Communication networks
• Content distribution networks
• Ad hoc networks
• Common functions

10
Future Work (II)

• Which in turn can be classified into areas of
• Service and functional requirements and service
  scenarios
• Functional architectures
• Mechanisms and procedures
• Deployment scenarios
• NGN project management will likely continue to be
  needed due to the wide ranging scope of the NGN
  related studies

11
Conclusion (I)

• The 20052008 study period has been an important
  and successful period for the development in
  ITU-T of NGN global standards which are the core
  of the evolving telecommunications networks
  meeting market needs of service providers and
  vendors
• Study Group 13 has played an important part in
  this success and believes that the work programme
  covered by the proposed new and revised questions
  will enable the ITU-T to continue provide the
  lead in the evolving NGN and beyond studies

12
Conclusion (II)

• Study Group 13 has pioneered new working methods
  for management and coordination of large
  projects spanning many study groups which have
  been successful and are being adopted in other
  work areas
• These have involved other SDOs who have worked
  with the ITU-T in the development of the NGN
  standards through participation e.g. in the JCAs

Acknowledgements

• Leading Study Group 13 over the past four years
  has again been a stimulating and challenging task
  and all involved in the study group can be proud
  of their achievements.
• I would especially like to thank the
  vice-chairmen for their faithful and very
  dedicated support to the Study Group 13
  management team and the TSB staff, particularly
  Georges Sebek and Gabrielle Regan for their
  guidance and tremendous support behind the
  scenes.
• Also I would like to thank all the rapporteurs,
  associate rapporteurs and editors who had served
  in these very important roles during the study
  period.
• Finally I would like to wish the new management
  team every success in the future NGN and beyond
  studies.
