  11/2004 and 3, 5, 7, 9, 11/2005
• ITU-T SG13 (NGN SG) became parent group of
  FGNGN (WTSA-04)

A Release is a method of prioritizing by
identifying a set of services to be addressed in
a certain time frame. The ITU-T NGN-FG should
progress the work to define the service
requirements and capabilities needed to realize
the services in addition to defining other
associated capabilities as needed to facilitate a
NGN in a first Release. The adoption of a
release-based approach will not prevent other
work, such as the development of more generic
(release independent) capabilities, and the
collation of services, requirements and issues
for later releases.
