Media Independent Handover Services and Interoperability Ajay Rajkumar Chair, IEEE 802.21 WG
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
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
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
Active Work Items • Media Independent Handover (MIH) Model • Event/Trigger service model • Information Service Ajay Rajkumar, Chair IEEE 802.21 WG
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
MIH Model • MIH Reference Model: 802.xx to 802.yy Ajay Rajkumar, Chair IEEE 802.21 WG
IEEE 802.xx to Cellular Ajay Rajkumar, Chair IEEE 802.21 WG
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
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
