ABSTRACT:
When a mobile node suffers an abrupt shut down while operating in a foreign network and recovers in its home network, the present invention enables the mobile node to reestablish communication capability, without time delay, with the nodes that had established one or more communication sessions with the mobile node prior to the abrupt shut down. The mobile node of the present invention includes an update module that determines whether additional information needs to be sent to the nodes in communication with the mobile node prior to the mobile node suffering an abrupt shut down. Based on that determination, the update module may provide additional information to such nodes.
