  • Patent number: 8873507
    Abstract: A method and system for optimizing mobility routing are disclosed. A preferred embodiment comprises a home local mobility anchor and two or more distributed local mobility anchors, wherein the distributed local mobility anchors have a reduced functionality from the home local mobility anchor. A first distributed local mobility anchor may send an initial data packet from a correspondent node to the home local mobility anchor, which may route the initial data packet to a second distributed local mobility anchor where a mobile node is anchored while also sending the location of the mobile node back to the first distributed local mobility anchor. Subsequent packets can be sent by the first distributed local mobility anchor directly to the second distributed local mobility anchor and bypassing the home local mobility anchor.

  • Patent number: 8824353
    Abstract: A method, system and device for achieving an optimized mobility routing path are disclosed. A preferred embodiment comprises a method of cutting unnecessary network tunnels. In a mobile network system, transmitting data packets through a tunnel is an effective way to provide network location privacy. An optimization method is proposed to consolidate two tunnels connecting with a network element such as a first distributed local mobility anchor (D-LMA). The first D-LMA informs a data packet sender such as a second D-LMA of the destination address saved in the first D-LMA. The second D-LMA updates its destination address accordingly and sends subsequent data packets to the destination directly. By applying this optimization method, a network system provides a further optimized route for data packets as well as location privacy.

  • 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.
