1. Why NGN ?

Separation btw. Services and Transport

  • Key Feature of IP : Anything over IP, IP over Everything

  • Most of Services using IP as their connection platform

  • Most of Networks supporting transport of IP packet

  • IP plays a key role to separate Services with Transport

1. Why NGN ?

Impacts to Policy and Regulation base

  • NGN provide a platform separating Services with Transport

  • Politics and Regulation environment would be impacted with this

  • Current Vertical environment would be changed to Horizontal env.

2. NGN Standardization

NGN 2004 Project

  • A new ITU Project on NGN : SG13, Nov. 2002

  • Project description document has been prepared(http://www.itu.int/ITU-T/studygroups/com13/ngn2004/index.html )

  • Fundamental characteristics for defining NGN

    • Packet-based transfer

    • Separation of control functions for bearer - call/session – service

    • Decoupling of services and network, provision of open I/F

    • Wide range of services (RT/ streaming/ non-RT/ multimedia)

    • BB capabilities with e2e transparency, incl.AN utilization

    • Interworking with legacy networks

    • Generalized mobility

    • Unfettered access from users to competing SPs and services

2. NGN Standardization

JRG on NGN

  • ITU-T SG 13 launched JRG-NGN at 1st August 2003 : 3 Meetings

  • Joint Special Rapporteur Group Activity within SG 13

  • Focus on “Foundational Documentation of NGN” until June. 2004

Draft Recommendations in AAP

Deliverables for further study

NGN Focus Group

  • ITU-T Director launched NGN Focus Group at June 2004

  • Almost every two month meeting : 6, 7, 9, 11/2004 and 2, 4, 6/2005

  • Functional & Nomadicity Architecture (base on IMS & non-IMS)

  • QoS (include the xDSL Access)

  • Security Capability (inc. Authentication)

  • NGN Control and Signaling Capability

  • Evolution from CGN to NGN

Definition & Features of NGN

Definition

of NGN

(Draft

Rec.

Y.2001)

A NGN is 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

functions are independent from underlying transport-related technologies.

It offers unrestricted access by users todifferent service providers.

It supports generalized mobility which will allow consistent and

ubiquitous provision of services to users.

Customer Manageable Capability

  • Capabilities to support user manageability on IP network.

  • Users can allocate, configure, control, and manage

  • the resources of NGN Network elements

4. Future Issues

Standards for Near Generation, not Next

  • NGN stands for Next Generation, but targeted for Near Generation

  • NGN could be value added framework for all players :

    Users, Operators, Providers and Regulators etc.

  • NGN could be evolved from Current Generation Network

  • NGN could be basement for making convergence world

    (real Telecommunication World)

  • NGN Standards could be Globalize rather than Localize

    boosting global village and shorten digital divide

  • ITU-T could be centre of NGN standards
