Definition of NGN

ITU-T

Rec.

Y.2001

Next Generation Network (NGN): a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functionsare independent from underlying transport-related technologies.

It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.

Clue for the Future Study

3. Future Study Directions

Changing Role of current network model; U-/C-/M-

• IP is the point for service offerings: Everything ov. IP ov. Anything

• Key role of below IP is providing connections; BW, QoS etc

• Signaling among distributed network element, not end-to-end

• Many different IDs for different services; E.164, Names, IP Add etc.

• User expectation for Management is changing; no interest

for connection or operation, only for services and businesses

New Paradigm: New model of User/Control/Management

Convergence should be a critical framework for Future

• Vision: Any Time, Any Where, Any Services and Any Devices

• Fixed Mobile Convergence should be the 1st instantiation

• Any information/services over any transport infrastructures:

VoDSL, TVoMobile, etc. (because of transport agnostic)
