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?

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-artBeyond UMTS R5, WLAN and PANAdvanced services including multimedia, media

scaling, personalisation, global mobility, etcNew roles and business models in a heterogeneous

access environment

– 4G is still to be defined (often only access)

Roadmap Beyond 3G (B3G)


Technology New 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*Kohei Satoh, DoCoMo Communications Laboratories Europe;”

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

Research challenges Understand security of different access systems

– Access versus application security– Security threats for application keys on SIM card

Application (scenario) based security infrastructure– Identify security requirements for service access– Establish hierarchical security (PKI?)

Near-field-communication related research– Enable PAN/mobile communication through NFC– Exchange and install applications/identity on phone
