ITU-T Study Group 19Mobile Telecommunication Networks John Visser
Contents • Terms of reference • Highlights of achievements • Future work • Conclusions • Supplemental slides
Terms of Reference • Network aspects of mobile telecom networks, including IMT-2000 and beyond, wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, and interoperability. • Lead SG for: • Mobile telecom networks • Mobility
Highlights of achievements • Close cooperation and coordination with ITU-R, 3GPP and 3GPP2 leading to Rec. Q.174x.y series: • Coupled with ITU-R Rec. M.1457, provides complete system specifications • 11th and 12th Recs. in series: Q.1741.5 and Q.1742.7 • Convergence: • Q.1762/Y.2802 Fixed-mobile Convergence General Requirements • Q.1763/Y.2803 Fixed mobile Convergence Service Using Legacy PSTN or ISDN as Fixed Access Network for Mobile Network Users • Q.FMC-IMS Fixed Mobile Convergence with a Common IMS Session Control Domain (anticipated will start approval process Jan 2009) • Mobility Management: • Q.1704 Functional network architecture for IMT-Advanced • Q.1706 Mobility Management Requirements for NGNs • Q.1707/Y.2804 Generic Framework of Mobility Mgmt for NGNs • Q.1708/Y.2805 Framework of Location Management for NGNs • Q.1709/Y.2806 Framework of Handover Control for NGNs Approved14 Oct 2008 Approved14 Oct 2008 Approved14 Oct 2008 Approved14 Oct 2008
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 19 • NGN has mobility as a fundamental capability • Mobility-related studies should continue as a discrete and highly visible block of work Note — 2007 data are estimates.

Future Work (II) • Key industry “megatrends”: • Everyone and everything is always connected • Range of devices, entities on the net far outpaces the number of people consuming the services they offer • Supported by telecoms enabled applications • Reinvented services & applications, network-aware intelligence, IMS* and SOA**: intuitive user experience • Supported by ubiquitous high speed access • Seamless 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! * IMS IP Multimedia Subsystem ** SOA Service Oriented Architecture
Conclusion • Telecoms / 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.
