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
DCN: 21-05-0238-00-0000
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

DCN: 21-05-0238-00-0000
Active Work Items
• Media Independent Handover (MIH) Model
• Event/Trigger service model• Information Service

Ajay Rajkumar, Chair IEEE 802.21 WG 6
DCN: 21-05-0238-00-0000
MIH Model
• Should it be a layer?• Should an API be defined?• Should transport be defined?
– For Remote triggers– For Local triggers

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
