Presentation Title

Next Direction of Info-Communication Technology, that is Medical ICT!

Abstract

No longer mobile wireless communication will be successful in near future. If we look at what's next in info-communication technology (ICT), then we note that a ubiquitous medical care system using ICT will be the most promised direction of academic and industrial R&D in ICT because of more population of senior citizens and less new babies. Japanese government has started a new five year strategic project in which medical ICT is the most significant innovation. This keynote speech will introduce the medicak ICT project in Japan in order to start collaborating with some counter partners in a world as well as providing many R&D themes in academia and industry.

Malcom Wardlaw (Vice President Mobility, Intelligence and Applications, BT)

Biography

Malcolm Wardlaw is currently responsible for the Mobility Architecture as well as the Intelligence and Applications Architecture, within BT’s 21CN programme. He holds a senior management position within the Group CTO. His early career was spent on Operating Systems, Call Control and IN and subsequently led much of BT’s technical development on Data Networks, SMDS, ATM, Frame, IP and MPLS – the Broadband enablers. For the last three years he has returned to real time Service Execution and Applications. He has championed Fixed-Mobile Convergence.

Presentation Title

Next Generation Networks for the 21st Century

Abstract

This keynote presentation will review the approach the Communication Service Providers are taking to Next Generation Networks. These service providers are moving to not only provide the traditional ‘Telco’ Fixed, Mobile and Internet Services, but also IPTV as well Applications based on Web Services. The presentation will explore these moves using BT as a primary example. BT has made a public commitment to replace its multiple core networks with a single converged IP core as well as replacing its TDM based PSTN networks with Soft Switches employing VOIP. Progress towards this new world with initial deployment plans and progress will be outlined.

A second part of this presentation will consider the services layer which most service providers are basing on IMS. This layer is being enhanced with a Service Oriented Architecture based primarily on ‘Web Services’ to create an open approach to service creation and delivery. Finally given the architectural principles being adopted at both the Network and Services layers some conclusions will be drawn about future directions for the Communications and IT industries.

Professor Hamid Aghvami (Kings' College London)

He is presently the Director of the Centre for Telecommunications Research at King’s. Professor Aghvami carries out consulting work on Digital Radio Communications Systems for both British and International companies. He has published over 420 technical papers and given invited talks all over the world on various aspects of Personal and Mobile Radio Communications as well as giving courses on the subject world wide. He was Visiting Professor at NTT Radio Communication Systems Laboratories in 1990 and Senior Research Fellow at BT Laboratories in 1998-1999. He was an Executive Advisor to Wireless Facilities Inc., USA in 1996-2002. He is the Managing Director of Wireless Multimedia Communications LTD (his own consultancy company).

He leads an active research team working on numerous mobile and personal communications projects for future generation systems, these projects are supported both by the government and industry. He was a member of the Board of Governors of the IEEE Communications Society in 2001-2003. He is a distinguished lecturer of the IEEE Communications Society, and has been member, Chairman, and Vice-Chairman of the technical programme and organising committees of a large number of international conferences. He is also founder of the International Conference on Personal Indoor and Mobile Radio Communications (PIMRC). He is a Fellow of the Royal Academy of Engineering, Fellow of the IEE, and Fellow of the IEEE.

Presentation Title

Wireless Access Network Design (In the context of end-to-end networking)

Abstract

This talk will first describe the concepts of convergence, integration and inter-working of multiple heterogeneous radio access networks.  It will then discuss the associated degrees of coupling between these networks.  The talk will give two different approaches for the design of next generation broadband wireless networks. It will also address how to ensure the establishment, maintenance and termination of end-to-end QoS for these two approaches.  As an example, the design of a wireless access network in the context of end-to-end networking will then be given. The suitability of the IP layer model as a glue to interconnect multiple heterogeneous radio access networks will next be addressed.  Following on from this, the NSF initiative on Future Internet Design (FIND) will be described as a means to re-invent the Internet architecture.
