ABSTRACT:
Particular embodiments provide an optimal allocation of a bearer manager or home agent. In one embodiment, a message is received from a mobile node requesting access to a visiting network that is different from a home network for the mobile node. An authentication request is sent to the home network requesting authentication for access. The authentication request indicates that a home agent has not been assigned. The home AAA server then sends a response that indicates the visiting AAA server can assign a home agent for the mobile node. The visiting AAA server then assigns a home agent that is optimally determined. The visiting home agent is different from a home agent that is found in the mobile node's home network. When a registration request is received, an IP gateway may send the registration request to the visiting home agent, which may not be sent back to the home network.
