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

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

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 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

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.

Brian 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.
