Enhancement user authentication,
seamless authentication
SIM authentication in 802.11 WLANs and 802.16 WiMAX
networks;
EAP-SIM; level 2 authentication
Personal device authentication over Near Field
Communication (NFC) and/or Bluetooth;
Session continuity with QoS within WLANs and WiMAX
Service roaming between 2G/3G/4G mobile networks and
WLANs and WiMAX networks.

Introduction
What is B3G or 4G?


Concepts are hard to define, since
– 3G will evolve
– 4G is not likely to be a single standard or a
standalone system
Proposal
– B3G is evolution from state-of-the-art
 Beyond
UMTS R5, WLAN and PAN
 Advanced services including multimedia, media
scaling, personalisation, global mobility, etc
 New roles and business models in a heterogeneous
access environment

Services and User Needs
Mobile Services Potential (estimation 2001)

Different researches predict that...
– m-commerce
– location based services
– entertainment
…will be the most potential mobile services in the
future
