January saw a gathering of hundreds of NGN experts in Geneva for the first NGN-GSI (global
standards initiative) event. Good progress was reported in several key areas
particularly in the important area of functional architecture and requirements
for resource and admission control functions (RACF) in NGNs. The Recommendation
covering RACF is said to be stable and is expected to be consented at the July
The January event comprised three full Study Group
meetings (11, 13 and 19). Experts from
various other Study Groups were in attendance for this first meeting of the GSI
following its launch in November, 2005.
Study Group 13, the lead for NGN work, alone saw over 250
contributions, many a result of the work of the Focus Group on NGN. SG 13 saw
three new Recommendations consented, see separate stories (Y.1731, Y.1452, Y.1453).
Group 11 reported that 50 contributions were received and launched work on
an NGN Protocol Set. According to SG documents ITU-T NGN-Protocol Set 1 will
define protocols for the support of:
· Network to Network Interface (NNI) session control;
· User to network Interface (UNI) session control;
· Resource Control Interfaces;
· Network Attachment Interfaces.
Protocol Set 1 is targeted for
completion by the end of 2006.
The chair of Study Group 19 reported good progress in the
area of FMC (fixed-mobile convergence).
It is expected that many other of the outputs of the Focus
Group on NGN will be consented at this July meeting. Among them will be a
Recommendation dealing with performance, management and measurement, another
key area in NGN. See the work programmes for the various Study Groups involved
in NGN for a full list.
