ABSTRACT:
A mobile node using Mobile IP is served by a network access server (NAS), wherein the NAS has allocated a care-of address for the mobile node and a home agent has a mobility binding that associates the care-of address with the mobile node's home address. When the mobile node's care-of address is no longer valid, an intermediary server receives a notification messages from a first network element (e.g., the NAS or home agent) and sends a resource management message to a second network element (e.g., the home agent or NAS). In response to the resource management message, the second network element clears at least one resource associated with the mobile node. For example, the NAS may de-allocate the care-of address and the home agent may clear the mobility binding.
