ABSTRACT:
Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.
