Some Issues:• service discovery• security• management• spectrum coexistence
BEYOND IMT 2000: SCENARIOS
First Generation
• Analogue• Circuit switched• Basic voice
telephony• Low capacity• Limited local
and regional coverage
Second Generation
• Digital• Circuit switched• Voice plus basic
data applications• Low data speed• Enhancements
towards• packet switching
• higher data rates
• Trans-national and global roaming
• Digital• Packet and circuit
switched• Data and
multimedia applications
• Medium data rates• Global coverage• Global roaming
Third Generation Beyond IMT 2000
• Digital• Packet switched• All IP based (IPv6)• More advanced
multimedia applications
• User in control• Flexible platform
of complementary access systems
• High speed data• Improved QoS• Global coverage• Global roaming

BEYOND IMT 2000: PROTOCOL ISSUES
New opportunity for DVB-T?
specific information to one user (P2P) mobile com.
unspecific information to all users in a given area broadcasting
Large memories introduce paradigm shift:– - ‘live services’ are already becoming the exception– - mass storage in receivers decouples consumption
from production (c.f. TV-Anytime) filter & store in user terminal local interactivity on stored content reaction by mobile communication (e.g. order a
product)

Integrating a 512 MB flash in the User Terminal should not be an issue in 2006; today prices of Flash EEPROM is around 0,3 €/MB
Capacity increase exceeds Moore’s law: factor 2 every year, at constant price
Based on present trends, a 0,01 €/ Mbytes could be reached in 2008

THE EU APPROACH TO>IMT 2000
CONCLUSIONS
EU fully committed to support the development of Systems beyond IMT 2000;
Approach based on interoperability and co-operative inter working of heterogeneous networks;
Standards will be critical to the overall success;
Standardisation requirements likely to move towards higher layers;
Standards time frame around 2007 ?;
Co operation between a multiplicity of fora may become critical
