Problem of network operators
More and more enriched services and content
on the Telecom networks are forcing the
bandwidth requirements to grow exponentially,
the cost of operators to great increase.
Even though more subscribers attracted by
enriched services, the annually decreasing
ARPU is causing operators’ margins to erode.

But, the NGSON is NOT …
The NGSON is NOT expected to solve all problems by
itself, but a fulcrum for network operators to solve
some critical problems by means of:
– Interconnection of large number of existing & emerging services
and enablers;
– Combination of advantages from both Telecom networks and
Internet;
– Protection & utilization of user information already exists;
– Optimization of network resources in a smart way.

Conclusion
 For almost all players in ICT, there are some bothering dilemmas
existing.
 IEEE NGSON is trying to solve these dilemmas through a serviceoverlay-network run by network operators, with context aware,
dynamically adaptive and self-organizing capabilities.
 Under this scheme, large number of existing & emerging services and
enablers will be interconnected, Telecom & Internet advantages will
be combined, protection and utilization of user information will be
balanced, and the network resources will be optimized in a smart way.
 The RD (requirement document) is going to be frozen soon, NGSON
WG is willing to cooperate with ITU-T and other related SDOs. Your
support and participate are appreciated.
