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)

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

Active Work Items
• Media Independent Handover (MIH) Model
• Event/Trigger service model• Information Service
![Page 6: DCN: 21-05-0239-00-0000 March 8, 2005 IETF 62 - Minneapolis, MN Media Independent Handover Services and Interoperability Ajay Rajkumar Chair, IEEE 802.21](https://reader036.vdocuments.net/reader036/viewer/2022082518/5697c00f1a28abf838cca7ba/html5/thumbnails/6.jpg)

DCN: 21-05-0239-00-0000
MIH Model
• Ongoing Discussion issues– Should it be a layer?– Should an API be defined?– Should transport be defined?
• For Remote 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
