Abstract:
A method and system for resilient mobile communications in a network when network elements are removed, upgraded or fail are provided. A mobile device communicates with an endpoint through foreign and home agents communicatively connected to the network. An active home agent stores communication information for the mobile node and multicasts the communication information to non-active home agents associated with the active home agent. When an active home agent is removed, upgraded or fails, the mobile device is able to maintain mobile communications with the endpoint through one or more non-active home agent. A non-active home agent having a high priority is transitioned to active status to maintain communication service between the mobile node and endpoint.
