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 


2. NGN Standardization

JRG on NGN

Deliverables on QoS for further study 


2. NGN Standardization

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

3. Key Features

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.


3. Key Features

Functional Architecture Model


3. Key Features

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
