ABSTRACT:
A method and system for Mobile Internet Protocol (IP) device redundancy. As mobile devices roam away from a home network and change a connective status, mobility binding records are sent to a multicast network address on the home network. The multicast network address multicasts the mobility binding records to other active Mobile IP home agent control nodes, standby home agent control nodes and standby home agents on the home network. The method and system allows standby home agent control nodes or standby home agents to be transparently switched for active home agent control nodes or active home agents that fail without downloading or uploading large numbers of mobility binding records after a failure. The method and system may also help reduce failed calls (e.g., data sessions including Voice over IP (VoIP), H.323, etc.), network congestion and improve user satisfaction in Mobile IP systems.
