  • Network address translation for tunnel mobility
    Patent number: 8345694
    Abstract: An access terminal identity based mobility is provided in which a first network tunnel is established between an access gateway and a first access router, and a second network tunnel is established between the access gateway and a second access router. At the access gateway, source addresses of packets sent from an access terminal to a remote correspondent node are translated by replacing the local address of the access terminal with the public address of the access terminal. The access terminal continuously maintain a communication session with the correspondent node as the access terminal moves from a first location to a second location and switches from accessing the first access router to accessing the second access router. A mapping between the local address and the public address is updated as the access terminal switches from the first access router to the second access router.

  • Geography aware peer-to-peer overlay creation
    Patent number: 8280376
    Abstract: In general, a first private access point detects a neighboring private access point. An address of the neighboring private access point is identified, and a peer-to-peer network that includes the first private access point and the neighboring private access points is formed.

  • NETWORK ADDRESS TRANSLATION FOR TUNNEL MOBILITY
    Publication number: 20090168788
    Abstract: An access terminal identity based mobility is provided in which a first network tunnel is established between an access gateway and a first access router that provides a first access point for access terminals, and a second network tunnel is established between the access gateway and a second access router that provides a second access point for access terminals. A public address is assigned to the access terminal having a local address assigned by the first or second access router. At the access gateway, source addresses of packets sent from an access terminal to a remote correspondent node are translated by replacing the local address of the access terminal with the public address of the access terminal. The access terminal continuously maintain a communication session with the correspondent node as the access terminal moves from a first location to a second location and switches from accessing the first access router to accessing the second access router.
