Terms of ReferenceResponsible for studies relating to the architecture, evolution and convergence of next-generation networks (NGN) including frameworks and functional architectures, signalling requirements for NGN, NGN project management coordination across study groups and release planning, implementation scenarios and deployment models, network and service capabilities, interoperability, impact of IPv6, NGN mobility and network convergence and public data network aspectsLead Study Group for: – Next Generation Networks– Satellite aspects


4


Highlights of achievements (I)During the study period, Study Group 13 examined 1437 contributions and drew up 59 new or revised Recommendations12 Recommendations currently under AAP or TAPNGN project management and coordination has been expanded Progress has been achieved in areas of – Packet based network studies – NGN functional architecture, mobility and

security – Service requirements and scenarios – QoS and OAM


5


Highlights of achievements (II)

Lead study group responsibilities for NGN and satellite aspects have been carried out – NGN JCA and NGN GSI established– ICG-SAT has achieved its purpose is now

proposed to be closed

Study Group 13 has managed Focus Groups on– Next Generation Networks– IPTV– Open Communications Architectures

OCAF transferred 22 component descriptionsto SG 13: April 2007

Focus Group OCAF terminated: Jan. 2008

Work continues within Question 16/13: ongoing


9


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 2005–2008 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 vendorsStudy 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 areasThese 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

AcknowledgementsLeading 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.

Thank you!B W Moore MSc BSc CEng FIETBrian Moore has been working in the telecoms standardisation field for over thirty five years and has held many chairmanships in CEPT, ETSI and the ITU in the area of network standards. He has been involved in standards development for data networks, signalling systems, the ISDN and Next Generation Networks. He was earlier involved in Study Group 7 (VII), Study Group 11 (XI) where he led the Signalling System No 7 Experts Group and Study Group 18 (XVIII) where he was chairman of the Signalling Working Party. Since 1993 he has been chairman of Study Group 13.Brian, after a career of over thirty years with British Telecom has for the past thirteen years been a consultant.
