  2. SWACOM WP2:User mobility and services continuity • Service Continuity • Mobile IP based: fast handover • SIP based: service management and authentication • 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. swacom.org - User Mobility

  5. IntroductionWhat 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 • 4G is still to be defined (often only access) swacom.org - User Mobility
