  • Patent number: 9049653
    Abstract: In one embodiment of the invention, a method for wireless communication includes receiving a packet destined to a destination node at a first egress router. The destination node is supported by a second egress router. A destination address of the packet is the first egress router. The received packet is redirected to the second egress router.

  • 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: 8730911
    Abstract: In accordance with an embodiment, a method of operating a first network configured to communicate with a first interface of a multi-interface user device is disclosed. The first network receives a first message from the user device, where the first message requests that messages for the user device be forwarded via a second network. The first network receives a second message for user device and forwards the second message to the second network.

  • Patent number: 8521161
    Abstract: A system and method for communications device and network component operation in an ID/Locator Split Based heterogeneous network is provided. A method for control node operation includes receiving an attach request, and attempting to authenticate/authorize the communications node. The attach request is a request from a communications node to attach to a heterogeneous network. The method also includes if the communications node authenticated/authorized successfully, causing an identification and a location to be assigned for the communications node, completing an attachment for the communications node, and transmitting information to the communications node. The method further includes if the communications node did not authenticate/authorize successfully, sending an attach reject message to the communications node. The identification and the location are separate values.

  • Patent number: 8413354
    Abstract: A system and method for performing a handoff is presented. A preferred embodiment comprises initiating a pre-handoff registration of a piece of user equipment prior to the actual handoff in order to pre-register the piece of user equipment with the new access network. During the handoff a tunnel may be created from the original access network to the new access network in order to tunnel data packets that would otherwise have been lost prior to the completion of the handoff.
