  1. SWACOM WP2: User mobility and services continuity Josef Noll, Prof. stip.UniK, josef.noll@unik.no www.swacom.org swacom.org - User Mobility

  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

  6. 4G ? "4G"-specification (2001 ?) 1991: UMTS- specifications 2002: UMTS roll-out 3G: 1982: GSM- specifications 1990: GSM roll-out 2G: 1969: NMT- specifications 1G: 1981: NMT roll-out 1970 1980 1990 2000 2010 From 1G to 4G swacom.org - User Mobility

  9. Roadmap Beyond 3G (B3G) B3G vision: User preferences Security, QoS, Price Appearance, User friendly Presence (context aware) Community (micro coordination connection, services) It works Services Media scaling Servicediscovery, Jini, Mobile Agents Management: network, security It is simple Technology Core Network Access network Terminals Supplementary technologies 1-2 Mbit/s everywhere 200 Mbit/s in hot-spots It is personalised 2001 2005 2008/2010 swacom.org - User Mobility

  10. 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 *Kohei Satoh, DoCoMo Communications Laboratories Europe;” Future Outlook Future Outlook for Fourth Generation Mobile for Fourth Generation Mobile Communications Communications System” ; EURESCOM P1145 Workshop; 26.06.2001; Kjeller, Norway swacom.org - User Mobility UP

  13. Services and User NeedsMobile Services Potential (estimation 2001) • Different researches predict that... • m-commerce • location based services • entertainment • …will be the most potential mobile services in the future • (sources: Wolk-Bryan 2000, Järvelä et al. 2001) swacom.org - User Mobility

  14. The Mobile takes it all SIM with RFID & PKI swacom.org - User Mobility

  15. * RFID, SIM & PKI Examples: & mHandel,VPN Haveto know Security Requirement * Needto know RFID & SIM passwd Intranet, email,Admittance & * & RFID (& SIM) Network access Nice to know Four-in-one: Your mobile integrates them all *Patent pending swacom.org - User Mobility

  17. 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 swacom.org - User Mobility
