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.

Introduction what is b3g or 4g
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)

Technology new access networks new cellular for 4g
TechnologyNew Access Networks- New Cellular for 4G?

Requirements for a new cellular access network*

  • High-speed transmission

    • Avg. 20 Mbps in cellular environment.

    • (Peak 100 Mbps)

    • Independent Up & Downlink speeds

  • High-capacity

    • >10 fold increase in 3-G

  • Good mobility

    • Supporting high-speed mobility.

    • Wide-range variable rate transmission is essential to extend coverage to indoor areas and to establish smooth handover to indoor systems
