METHOD AND APPARATUS TO FACILITATE FOREIGN AGENT ACTIONS WITH RESPECT TO HOME AGENT NONRESPONSIVENESS

摘要

A foreign agent (10) having a substantially static list (13) of one or more home agents, the foreign agent (13) using a Home agent responsive evaluator (14) for determining when a given home agent has become sufficiently nonresponsive with respect to an ability to support mobile Internet Protocol calls. Upon making such a determination, the foreign agent (10) can optionally take one or more predetermined actions. Such actions preferably serve to mitigate or ameliorate the consequences presented by a nonresponsive home agent with respect to support mobile Internet Protocol calls.
