• ITU-R Draft New Recommendation (DNR): Vision, framework and overall objectives of future development of IMT-2000 and systems beyond IMT-2000
• Adopted at the 9th meeting of WP8F (October 2002)
• Submitted for approval at the next meeting of ITU-R Study Group 8 (February 2003)
• ITU-R Preliminary Draft New Report (PDNR): Technology Trends
• Scheduled for completion and adoption at the 11th meeting of WP8F (October 2003)
Market TrendsMarket Trends
• Growing demand for mobile services• The number of mobile subscribers worldwide has increased from 215 million
in 1997 to 946 million (15.5% of global population) in 2001 as shown in Figure 4-1[1].
• It is predicted that by the year 2010 there will be 1 700 million terrestrial mobile subscribers worldwide.
• Trends in services and applications• Users will expect a dynamic, continuing stream of new applications,
capabilities and services that are ubiquitous and available across a range of devices using a single subscription and a single identity (number or address).
• Multimedia traffic is increasing far more rapidly than speech, and will increasingly dominate traffic flows. There will be a corresponding change from predominantly circuit-switched to packet-based delivery.

High Level VisionHigh Level Vision
• Future development of IMT-2000• There will be a steady and continuous evolution of IMT-2000 to
support new applications, products and services.
• New capabilities of systems beyond IMT-2000• There may be a requirement for a new wireless access
technology for the terrestrial component to complement the enhanced IMT-2000 systems and the other radio systems.
• Need to support data rates of up to approximately 100 Mbit/s for high mobility, such as mobile access
• Need up to approximately 1 Gbit/s for low mobility such as nomadic/local wireless access.
High Level VisionHigh Level Vision
• Relationship of IMT-2000, systems beyond IMT-2000 and other access systems:
• Continuing to develop between different radio access and communications systems, for example wireless PANs, LANs, digital broadcast, and fixed wireless access.
New capabilities for systems beyond IMT-2000 New capabilities for systems beyond IMT-2000
• It is anticipated that there will be a requirement for a new radio access technology or technologies at some point in the future to satisfy the anticipated demands for higher bandwidth services.
• Systems beyond IMT-2000 will:• Support a wide range of symmetrical, asymmetrical, and unidirectional services
• Provide management of different quality of service levels to realize the underlying objective of efficient transport of packet‑based services.
• In parallel, there will be an increased penetration of nomadic and mobile wireless access multimedia services.
• The technologies, applications and services associated with systems beyond IMT-2000 could well be radically different from the present, challenging the perceptions of what may be considered viable by today's standards and going beyond what can be achieved by the future enhancement of IMT-2000 working with other radio systems.
Communications relationships between devices in the three domains
Communications relationships between devices in the three domains
• A similarity of services and applications across the different systems is beneficial to users, and this has stimulated the current trend towards convergence
• The increasing prevalence of IP-based applications is a key driver for this convergence and facilitates the establishment of relationships between previously separate wireless platforms.
• The formation of these relationships is distinct from the development of each wireless access system, including IMT-2000;

Future network of systems beyond IMT-2000 including a variety of potential interworking access systems
• Different radio access systems will be connected via flexible core networks, allowing individual users to be connected via a variety of different access systems to the networks and services he desires.
• The interworking between these different access systems in terms of horizontal and vertical handover and seamless service provision with service negotiation including mobility, security and QoS management will be a key requirement, which may be handled in the core network or by suitable servers accessed via the core network.
• This "Optimally Connected Anywhere, Anytime" vision could be realized by a network comprising a variety of interworking access systems connected to a common packet-based core network.

TimelinesTimelines
• Timelines for the future development of IMT-2000 and systems beyond IMT-2000 depend on a number of factors:
• market trends, requirements and user demands;
• technical capabilities and technology developments;
• standards development;
• spectrum availability, including allowing sufficient time to re-locate systems that may be using proposed bands;
• regulatory considerations;
• system (mobile and infrastructure) development and deployment.

RecommendationsRecommendations
• Standardization• that detailed standardization of the radio interface(s) should take
into account the frequency band(s) in which it is intended to be used;
• that global and open standardization of the radio interface specifications should continue in the future to realize the benefits of mass market and ensure inter-operable equipment so that users, operators, manufacturers, etc. can continue to benefit from mobile communications;
• that the level and type of standardization should be adapted to meet technical and market requirements at that time;
• that standardization should be performed in a timely manner prior to system deployment and should take into account the availability of spectrum and market considerations;
RecommendationsRecommendations
• Focus areas for further study • that research forums and other external
organizations wishing to contribute to the future development of IMT-2000 and systems beyond IMT-2000, are encouraged to focus especially in the following key areas:
• radio interface(s);
• access network related issues;
• spectrum related issues;
• traffic characteristics;
• market estimations.
