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.

Key Principles of NGN
� Open architecture: open to support service creation,
service updating, and incorporation of service logic
provision by third parties and also support “Distributed
control” as well as enhanced security and protection.
� Independent provisioning: service provision process should
be separated from network operation by using distributed,
open control mechanism to promote competition.
� Multiplicity: The NGN functional architecture shall offer
the configuration flexibility needed to support multiple
access technologies.

Key Features of ITU-T NGN
1. Key Features of ITU-T NGN
� Packet-based transfer ;� Separation of control functions among BC, call/session,
and application/ service;� Decoupling of service provision from transport ;� Support for a wide range of services based on servic e building blocks;� Broadband capabilities with end-to-end QoS;� Interworking with legacy networks via open interfaces;� Generalized mobility ;� Unfettered access by users to different service providers;� A variety of identification schemes;� Unified service characteristics for the same servic e as perceived by the user;� Converged services between fixed/mobile ;� Independence of service-related functions from unde rlying
transport technologies;� Support of multiple last mile technologies;� Compliant with all regulatory requirements
(e.g. emergency, privacy, lawful interception, etc. )

NGN; a Convergence Platform
� Combination IP with Broadband accelerating intrinsic convergence
• Service convergence: Web based service provisioning
• Network convergence: IP over any broadband transport networks
� Advanced Mobile and Wireless technology initiate business
convergence such as Fixed-Mobile convergence
� Broadband Fixed, Wireless and Mobile technology boost another
business convergence, called “Multiple Play: Tele-Broadcasting”

Clue for the Future Study
4. 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)
