Future Work (I)At WTSA-2000, prediction that mobile would soon outnumber fixed subscribers led to establishment of SSG

– Became global reality in 2002– Today, nearly all subscriber growth is mobile

WTSA-2004 recognized importance of mobility by upgrading SSG to SG 19NGN has mobility as a fundamental capability

– Mobility-related studies should continue as a discrete and highly visible block of work

Future Work (II)Key industry “megatrends”:

– Everyone and everything is always connectedRange of devices, entities on the net far outpaces the number of people consuming the services they offer

– Supported by telecoms enabled applicationsReinvented services & applications, network-aware intelligence, IMS* and SOA**: intuitive user experience

– Supported by ubiquitous high speed accessSeamless communications experience: anywhere, anytime, any convenient device, and economical

Industry directions point to two “super” work groupings with sub-groups as needed:

– Telecommunications Enabled Applications– Infrastructure / Transport

Timely global standards are essential!

* IMSIP Multimedia Subsystem

** SOA Service Oriented Architecture

ConclusionTelecoms / ICT is entering a new era– Megatrends: hyperconnectivity supported by

telecoms enabled applications, seamless broadband for everyone

Mobility is fundamental– Next 1B subscribers will all be mobile

Essential to recognize industry trends and organize accordingly– ITU-T’s relevance and future success depends

on it!

Thank you!John has served ITU-T in various roles and positions over the past 24

years, including appointment at WTSA-2000 as Chairman of the Special Study Group (SSG) on “IMT-2000 and beyond”. When the SSG became SG 19 at WTSA-2004, John was appointed its Chairman.

Throughout his career at Nortel, John’s ongoing close coupling with design, product line management and marketing teams has been an essential element of his successes in standards. John has also had extensive involvement in ANSI T1, TIA TR45, 3GPP2, and has participated in ITU D, ITU R, 3GPP, APT and the WiMAX Forum among others.John leverages his standards leadership in working with ITU-D and ITU-T in organizing, chairing and presenting at seminars and workshops on 3G, Next Generation Networks and other topics around the world. In the past five years, he has been involved in some 13 such events (chairing many of them) and has given over 60 presentations around the world, including Europe, the CIS countries, the Middle East, Africa, Asia-Pacific, and the Americas.John earned a Bachelor of Applied Science in Electrical Engineering from the University of British Columbia in 1973. He served as a communications engineer with the Canadian Armed Forces, achieving the rank of Captain. John joined Bell-Northern Research, the R&D arm of Nortel, in 1978. He is currently part of Nortel’s Strategic Standards Team in the CTO Office, and is based in Ottawa, Canada.John is a Registered Professional Engineer in Ontario, Canada, and is a member of IEEE.
