The Promise of IMS - Myth vs. Reality
Chair: R. Thanawala, Bell Labs, Lucent Technologies, Holmdel, USA

S. Ahuja, VP Convergence Networks and Services Research, Bell Labs, USA
B. Jarry-Lacombe, Network Design and Architecture, France Telecom

It takes between 10 to 14 months for an operator to introduce a new service. In the Internet world, its around three months. The promise of IMS is reducing time to revenue for new services including being able to cost effectively experiment
with new services - withdrawing services that don't hit the mark and turning promising services into winners, all the time blending services to create value that users are
willing to pay for. However there are lots of issues -  interoperability, getting started costs, etc.  Are these just maturity issues associated with  the introduction of any new change-the-paradigm technology, or are these so significant that the advantages of IMS are not likely to be realized? This hot seat session will be a lively exploration of
views between two leading industry executives on both the business and technology issues surrounding IMS. Sid Ahuja, Vice President of the Converged Networks
and Services Research Laboratory at Bell Labs, and a champion for IMS will present the case for IMS. Bernard Jarry-Lacombe, who is responsible for Network Design and Architecture at France Telecom will present an Operator perspective.

Should Voice be Free? Alternative Emerging Business Models - Are they sustainable?
Sessionchair: A. Valdar, University College London, UK

A. Antonopoulos, Business School, University of Budapest, Hungary and partner at Working Knowledge Consulting Company
A. Das, BT, India

The apparent value of a voice call, once the staple source of revenue for network operators, has been declining at an alarming rate.  Whether it is through the death of distance, the commoditisation due to competition, or the rise of voice over IP substitutes, the cellular and fixed network operators are experiencing rapid declines in price of voice.  But is this trend to free voice sustainable?  Are there viable new commercial models to cope with this?   These and other questions will be addressed during this Hot Session, taking the perspectives of established network operators as well as new players.

Access: The Last Mile - When is Copper at its End?
Chair: J. Gross, Arcor AG & Co. KG, Germany

O. Gordien, Alcatel, India
A. Ciarniello, Telecom Italia Mobile, Italy

Internet connectivity is a neccessity for so many people now... to communicate, to get information, entertainment (e.g. IP-TV, VoD) and to be a part of the internet community to distribute information, videos or pictures. Access decisions have huge leverage on the operator's ability to meet business objectives. An expert panel will discuss some of the key questions:
Who is in the best position to provide access to the end user - the mobile or fixed network
operator, the Network provider or ISP?
What is the bandwidth demand for existing and future services?
What is the best and most economical access strategy for the greenfield operator?
What about an operator who has an existing infrastructure?
What is the best access technology to serve these demands-  WIMAX, UMTS,
Coax, Copper, FTTX?

Broadband Wireless Perspectives

A. Wahi, Alcatel, India
P. Janek, Hungarian Telekom, Budapest, Hungary

One of the most prominent trends in today's telecommunication landscape is the widespread deployment of wireless technologies as the "last mile" connection for delivering POTS and broadband Internet access. The emergence of different wireless local loop (WLL) technologies can unlock competition, enabling new operators to bypass existing wireline networks and spare the costly deployment of copper-line, cable or fiber links. This section will focus on the benefits of such WLL solutions, with special emphasis on WiMAX, the most promising WLL technology.

17:00 - 17:45  Keynote 2

The Future of Networks - Summarizing Trends
A. Valdar, University College London, UK

Never have the challenges facing this industry been so great! Having survived the decimation of the market crash of 2000, the Telcos are now facing not only technical and cost challenges - but also the profound reshaping of the commercial model and values relating to their services.
Structurally, the industry is witnessing a rise in mergers and acquisitions as the long-awaited consolidation of the operators and the equipment manufactures takes off. In addition, the value of switched voice and bandwidth - the staple money-generating services for Telcos - continues to diminish, driven by the rise of voice-over-IP-based services and the rapid rollout of broadband to the consumer market.  The current responses to this situation include the adoption of next-generation network technologies to drive down costs through platform integration - together with all the forms of service convergence (fixed-mobile, communications and entertainment, "triple" and "quadruple play", etc).
This presentation considers how these factors are creating such a challenging agenda for the major network operators over the next five years. 

17:45 - 18:00  Closing Remarks
