Presentation Transcript

  1. Media Independent Handover Services and Interoperability Ajay Rajkumar Chair, IEEE 802.21 WG

  2. Scenarios considered by 802.21 WG • Between 802.xx and 802.yy • 802.3 • 802.11 • 802.15 • 802.16 • Between 802.xx and Cellular • 3GPP standards • 3GPP2 standards • Between 802.11 ESS Ajay Rajkumar, Chair IEEE 802.21 WG

  3. What does Heterogeneous Handover Mean? • Session Continuity at the IP layer • Adaptation to new link at layer two • Address continuity at layer three • Service Continuity at the Application layer(s) Ajay Rajkumar, Chair IEEE 802.21 WG

  4. Functional Requirements • Service Continuity • Independent of Architectural Deployment of individual interfaces • Class of Application • Quality of Service (QoS) • Network Discovery • Information Discovery (Network Selection) • Security • Power Management • Handover Policy shall not be defined Ajay Rajkumar, Chair IEEE 802.21 WG

  5. Active Work Items • Media Independent Handover (MIH) Model • Event/Trigger service model • Information Service Ajay Rajkumar, Chair IEEE 802.21 WG

  6. MIH Model • Ongoing Discussion issues • Should it be a layer? • Should an API be defined? • Should transport be defined? • For Remote triggers Ajay Rajkumar, Chair IEEE 802.21 WG

  7. MIH Model • MIH Reference Model: 802.xx to 802.yy Ajay Rajkumar, Chair IEEE 802.21 WG

  8. IEEE 802.xx to Cellular Ajay Rajkumar, Chair IEEE 802.21 WG

  9. Event/Trigger service model • Local Triggers • From/to MIH • Peer-to-peer Remote Triggers • Across access interfaces as MIH messages • Across network elements • Several modes of transport • Media specific transport • IP based • MAC based • 802.21 specific Ethertype Ajay Rajkumar, Chair IEEE 802.21 WG

  10. Information Service • Link access parameters • Security mechanisms • Neighbor maps • Location • Provider and other Access information • Cost of link Ajay Rajkumar, Chair IEEE 802.21 WG

  11. Call for Proposals -Timeline • CFP Issued on September 28, 2004 • Intent to Propose deadline was October 10, 2004 • Initial submissions deadline was November 8, 2004 • Initial presentations during November Plenary • Updated submissions deadline, January 10, 2005 • Updated proposal presentations during January Interim • Initial presentations complete • Ongoing harmonization and evaluation of proposals • Initial draft text scheduled for May 2005 Ajay Rajkumar, Chair IEEE 802.21 WG

  12. Thank YouQuestions and Feedback? Ajay Rajkumar, Chair IEEE 802.21 WG
