Why NGN?
The NGN concept takes into consideration new realities in the telecommunication industry characterized by factors such as the need to converge and optimize the operating networks and the extraordinary expansion of digital traffic (i.e. increasing demand for new multimedia services, increasing demand for mobility, etc.) NGN also aims to tackle important concerns raised from the use of current IP-based services: (i.e. QoS and security)

Definition of NGN: Y.2001
ITUITU-T SG 13: Rec. Y.2001
A NGN is a packet-based network able to provide packettelecommunication services and able to make use of multiple broadband, QoS-enabled transport QoStechnologies and in which service-related functions serviceare independent from underlying transport-related transporttechnologies. 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.

Definition of NGN: Y.2001
(2/2)
NGN is characterized by the following fundamental aspects:
Packet-based transfer; Packet Separation of control functions among bearer capabilities, call/session, and application/ service; Independence of service-related functions from underlying transport technologies; service Broadband capabilities with end-to-end QoS and transparency; end-to Unrestricted access by users to different service providers; Generalized mobility; Converged services between fixed/mobile; Interworking with legacy networks via open interfaces; Support for a wide range of services, applications and mechanisms based on service building blocks (including real time/ streaming/ non-real time services and multinonmultimedia) Unified service characteristics for the same service as perceived by the user; Compliant with all regulatory requirements (e.g. emergency, privacy etc.) Decoupling of service provision from network, and provision of open interfaces; A variety of identification schemes which can be resolved to IP addresses for the purposes of routing in IP networks

Overall Coordination (3/4)
To help SG 13 (particularly Q.1/13) in the overall management of the NGN µproject¶ September 2006: Implemented NGN Project Management Tool (database)
Web-based database Provide consolidated information (acting as a repository) on NGN standardization work in ITU-T and other relevant SDOs.
Key features: on line ability to see the latest versions of documents. ability to sort out work items by function or entity
15.11.06
Overall Coordination (4/4)
To reinforce the role of the NGN-JCA and ensure visibility
November 2005 established NGN-GSI TSR NGN-GSI Technical and Strategic Review
ensure technical coherence to NGN studies provide inputs to NGN-GSI for strategic and technical co-ordination to NGN work
Each NGN-GSI event will comprise TSR meeting(s), which will report to NGN-JCA any issues requiring guidance or recommendations for action (e.g. concerning work allocation)

Key QoS Challenge Tackled
New Rec. Y.1542 gives the groundwork for service providers to realize end-toend network performance for services like VoIP and IPTV. With Y.1542, NGN will be able to provide QoS across multiple network operators, and unusual topologies and distances. Y.1542 is complementary to Y.1540 and Y.1541 which give network performance objectives for IP-based services Y.1542 gives guidance to accelerate the planning, deployment and management of interoperable networks and systems
