  • Patent number: 8767622
    Abstract: Method and system for managing address prefix information associated with handover in network. A fast handover process is achieved for point-to-point communication model. A mobile node send a provisional new care-of-address with an aggregate prefix part to its previous access router, which forwards the address to a new access router. The new access router in response generates a modified new care-of-address with a unique prefix part for the mobile node. Alternatively, the mobile node sends a request to the previous access router for a unique prefix. The request is forwarded from the previous access router to the new access router. The new access router assigns a unique prefix for the mobile node.

  • Patent number: 8599843
    Abstract: Disclosed herein is a route optimization that allows packets flowing between a mobile node (MN) and a correspondent node (CN) to bypass local mobility anchors (LMAs), thereby improving flow efficiency and/or reducing network traffic. Specifically, the MN's mobile access gateway (MAG) and the CN's MAG may participate in a proxy binding update (PBU)/proxy binding acknowledgement (PBA) exchange with each other to establish the MN's and CN's state in the opposing MAG. After doing so, the two MAGs may send MN-CN packets directly to each other, e.g. without sending such packets to the LMAs. In one embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with the same LMA. In another embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with different LMAs.
