Abstract
A method and apparatus for robust mobility management in a network having a mobile node (MN), a mobility anchor point (MAP), a correspondent node (CN1, CN2), a home agent (HA) and an access router (AR1) and operating under a hierarchical protocol. The mobile node (MN) sends the address (102, 104) of the mobility anchor point (MAP) to the correspondent node (CN1, CN2) and sends the address (106, 108) of the mobile node (MN) on the network of the access router (AR) to the home agent (HA) and to the mobility anchor point (MAP).
When failure of the mobility anchor point occurs, the mobile node recovers from the failure by selecting a new mobility anchor point or operating under a non-hierarchical protocol. Failure is detected by an intermediate router or by a correspondent node when messages fail to reach the mobility anchor point.
When failure of the mobility anchor point occurs, the mobile node recovers from the failure by selecting a new mobility anchor point or operating under a non-hierarchical protocol. Failure is detected by an intermediate router or by a correspondent node when messages fail to reach the mobility anchor point.
