• After 18 months of intensive activity the NGN Focus Group, at end of 2005, handed over its results to Study Group 13 and other relevant study groups to continue the development of global NGN standards

ITU-T NGN Focus Group


Ongoing arrangements

• At its meeting in September 2005 Study Group 13 put in place the arrangements for the ongoing NGN work

• A major consideration in the future planning was the need to continue to have a visible focus for the NGN work and to maintain as far as possible the co-location of the closely related NGN work performed under the umbrella of a coordinated work plan


• To achieve this the ITU-T NGN Global Standards Initiative (NGN-GSI)* was established under which the ongoing work is being done by the Study Groups and their Rapporteur Groups meeting together as necessary according to an NGN work plan being coordinated by Study Group 13

* See http://www.itu.int/ITU-T/ngn/index.phtml

The ITU-T NGN-GSI


Technical and Strategic Review

• It was also agreed to set up under the NGN Joint Coordination Activity (NGN-JCA)* a new Strategic and Technical Review function (TSR) which would at every NGN-GSI event perform technical coordination of the NGN work across the various study groups

*See http://www.itu.int/ITU-T/studygroups/com13/ngnjca/index.html


Expansion of the NGN-JCA

• In addition representatives of the GSC

PSO’s were invited to participate in the

NGN-JCA in order to help provide the

strategic direction to the ongoing global

NGN standardisation work and to help

foster good collaboration amongst the

various organisations


GSI: Umbrella over the NGN standardisation programme

JCA: ITU-T, GSC PSO’s and IETF managers: oversees

coordination and planning of work TSR: Review results, identify issues to JCA

NGN-GSI overview


NGN-GSI events

• Two NGN-GSI events have so far been held

– Meetings of Study Groups 11, 13 and 19

together with WP2/17 and representatives of

Study Groups 12 and 16 were held in

Geneva, 16 to 27 January 2006

– Co-located NGN Rapporteur meetings were

held in Kobe, Japan, 22 to 27 April 2006


Highlights of the Kobe NGN-GSI event

• 16 Rapporteur groups of Study Groups 11, 13 and 19 met

• Over 200 contributions• Over 200 delegates from 79 companies and 19

countries• Over 30 draft recommendations progressed of

which 11 are candidates for ‘consent/determination’ at the July 2006 meeting:– NGN R1 requirements– Functional requirements and architecture of the NGN


– NGN mobility management requirements– IMS for Next Generation Networks– Functional architecture and requirements for resource

and admission control functions– NGN security requirements– PSTN/ISDN evolution to NGN– PSTN/ISDN emulation architecture– PSTN/ISDN emulation and simulation– Call Server based PSTN/ISDN emulation– Tandem free operation (TFO)–IP network interworking

– user plane interworking


• Future NGN-GSI events so far scheduled are:– July 2006 Study Group and Rapporteur

meetings– October 2006 NGN Rapporteur meetings– January 2007 NGN Rapporteur meetings– April 2007 Study Group and Rapporteur

meetings– September 2007 NGN Rapporteur meetings

Future NGN-GSI events


Workshops on NGN• The following workshops have been held:

– NGN Industry Event, London, 18 November 2005

– Joint ITU-T/ATIS workshop on NGN Technology and

Standardisation, Las Vegas, 19-20 March 2006

– Workshop on NGN and its Transport Networks, Kobe,

20-21 April 2006

– Workshop on NGN, Hanoi, 15-16 May 2006

• Joint ITU-T/GGF workshop on NGN and Grids to

be held in Geneva, 23-24 October 2006


New topics

• The NGN space is expanding. New topics having an impact on NGN include:– RFID– IPTV– Grids

• The scope of the NGN programme will be expanded to include the necessary standards work


Activities of the NGN Management Focus

Group(Provided by Chairman of Study

Group 4)


NGN Management Focus Group(NGNMFG)

• Established by ITU-T SG 4 in Sept 2004 at FGNGN request to support NGN Release 1

• Involves leaders and other participants of major SDOs, forums, and consortia

• Focused on the following (FCAPS) management interfaces:– Network Element – Management System– Management System – Management System

(FCAPS - Fault, Configuration, Accounting, Performance, and Security Management)


NGNMFG – Status

• Updating NGN Management Specification Roadmap focused on Release 1 which identifies– Requirements

– Framework, principles, and architecture

– Interface specifications, both protocol-neutral and protocol-specific

• Generic information models latest addition

• Identifying specification “overlaps” and stimulating their owners to harmonize them

• Identifying “gaps” and best organization(s) to fill the gaps


NGNMFG Harmonization Activity

• Management architecture: SG4, TISPAN, TMF

• Alarm reporting: TMF, 3GPP, SG4, DMTF

• State management: TMF, 3GPP

• Accounting, charging, and billing– At request of NGNMFG/SG4, ATIS TMOC and 3GPP

SA5 proposed application guidelines

• Ethernet management: SG4, MEF, TMF

• Information Models (many SDOs/forums)– 2 fold focus: generic, NGN functions

• XML-based framework and models (many SDOs/forums)


NGNMFG - Summary• Leadership

– Chair: Dave Sidor (Nortel Networks)– Vice Chair: Leen Mak (Lucent Technologies)

• Participation– Open; individuals from founding organizations encouraged– Registration required: see http://www.itu.int/ITU-T/studygroups/com04/ngn-mfg/index.html

• Time schedule– Roadmap Version 1 submitted to SG 4: September 2005– Roadmap Version 2 to SG 4: May 2006

• Working methods– Decision-making via consensus– Virtual meetings, but f2 f meetings allowed– Any specifications produced are candidates to be SG 4

Recommendations
