Abstract
Providing resiliency for mobile terminal data sessions, wherein the data sessions rely on Internet Protocol Version 4 and wherein at least one Home Agent node maintains a mobility bindings database for all registered mobile terminals while they are away from a home network. A first aspect of the invention provides physical Home Agent redundancy, perceived by each mobile node as Home Agent IP address redundancy, and a second aspect provides session resiliency. While the second aspect of the invention provides for session resiliency, it uses a mechanism of the former for master failure detection and Home Agent IP address take-over by a backup Home Agent.
