Successful GlobalNGN Standards


What is happening?

• Unprecedented changes occurring at unprecedented speed

• Major technology shifts mean major growth opportunities and major risks

• Major opportunities for synergies, reuse through convergence: telecoms/IT, fixed/mobile, broadcast

• Regional and global NGN standards initiatives already underway


What is NGN?

• ITU-T SG 13 definition: – a packet-based network providing Telecom

Services using multiple broadband, QoS-enabled transport technologies

– service functions independent of transport– unrestricted user access to different service

providers– supports generalized mobility allowing

consistent, ubiquitous provision of servicesSG 13 TD-28 (GEN) 3-12 Feb 2004


SG 13 definition -NGN Characteristics

– Separation of bearer, call/session, and application/service control

– Services via building blocks (incl. real time/ streaming/non-real time, multi-media)

– Converged services between fixed/mobile– Service provision decoupled from network– Legacy interworking– Generalized mobility– Appropriate NNAR schemes

SG 13 TD-28 (GEN) 3-12 Feb 2004


Convergence Example

• Listen to streaming audio from an Internet radio station, on a mobile terminal, ...– mobility (mobile terminal)– broadcast (radio station)– IT (Internet data stream)

• ... receive stock price updates, ...

• ... and take a call from the boss ...

All at the same time*!

vs.

* User may wish to suspend streaming audio while talking to the boss!

Network Profile


NGN Standards

• Who’s working on NGN standards?– Everyone!– All standards development is based on

expectation of follow-on implementation and deployment


NGN Standards Already Underway

• ITU-T standards for NGN:– SG 13: several NGN Recs. target Jun 2004– SSG: fixed/mobile convergence: Rec. Q.1761– results, ongoing work on multimedia services,

architectures, signalling, transport, QoS, etc.

• ETSI TISPAN

• Multiple local, national, regional activities

• Multiple approaches and technologies being positioned as “NGN”


NGN Standardization Requirements

NGN standardization process must be:• Global

– multi-regional inputs essential• Fast

– responsive to market needs• Convergent

– fixed/mobile, IT, broadcast, ...• Efficient, open and transparent, inclusive

– well-run processes, accessible by all• Based on cooperation and collaboration

– among standards organizations


Candidate Solutions

• New NGN Partnership Project

• Existing Global SDO

• Combination


New NGN PP?

• Is a new partnership project for NGN standards the best approach?– access through existing SDOs: excluded if not

an existing SDO, or your SDO is not a partner– concern over costs to establish, maintain– concern over potential loss of continuity

needed in developing all standards required for end to end solutions

– must bring specs to ITU-T anyway: much of global marketplace insists on ITU-T standards


Existing Global SDO?

• Is an existing global SDO for NGN standards the best approach?– ITU established 1865: long history– mission: compatibility of international

telecommunications on a worldwide basis– member willingness: rapid technical progress– private sector plays key role in technical

standards development process– expertise across all aspects; no barriers to

having the right experts to drive the work


Combination?

• Is a combination the best approach? – Global: would stimulate development of a consistent

framework within which essential multi-regional inputs will fit

– Fast: regional inputs will be responsive to their market needs; ITU-T processes now very fast

– Need for convergence recognized by everyone– Efficient, open and transparent– Fully inclusive: accessible by all– Success through cooperation and collaboration:

demonstrated by SSG and 3GPPs


Regional Inputs to a Global Framework


ITU-T is a Global Partnership

• 189 Member States

• Sector Members:– 162 ROAs, 171 SIOs, 84 Associates– 47 others including ISOC, regional and

international organizations, etc.

• MoUs– IEC, ISO, ETSI

• Fora and Consortia– Recs. A.4, A.5, A.6 ITU- TSB: Feb 2004


Success factors

• Must have a way for regional initiatives and urgent needs to be met in a globally consistent context

• Must have clear roles and objectives laid out for all players to deliver the needed standards– who will do what and when– how it all fits together– how it will become a global standard


Role for ITU-T

• Establish the global framework– for consistent fit of regional perspectives

• Everyone benefits from reduced costs enabled by global consistency– operators need to interconnect– vendors need economies of scale from

globally consistent interfaces– users benefit from innovative and consistent

telecommunciations services


Role for Regions

• Meet regional needs– respond to own market needs– meet everyone’s need for convergence

• Ensure fit into global framework

• Success through cooperation and collaboration


Conclusion

• The essential elements and success factors for developing essential NGN standards clearly point to strong collaboration and cooperation of regional activities in combination with ITU-T as the global SDO
