  • Method and system for secure exchange of data in a network
    Patent number: 8190897
    Abstract: A first network device implements a method for the secure exchange of data in a network. The network also includes a second network device and a remote device. The method includes establishing an indirect path to the remote device and pre-negotiating first security parameters with the remote device over the indirect path using a network layer protocol, when the second network device has an active first data link. The method further includes establishing an active second data link with the remote device and exchanging first data with the remote device over the active second data link using the first security parameters, when the first data link becomes inactive.
    Type: Grant

  • Methods and apparatus for use in a packet data network
    Patent number: 8184618
    Abstract: A GGSN receives a request associated with a session creation for a mobile entity. The GGSN begins a process (a four-way handshake) for obtaining network access configuration parameters for the mobile entity and responds to the request prior to the completion of the four-way handshake. The GGSN then completes the four-way handshake. A GGSN creates an association between a first IP address and a first mobile entity and thereafter requests an IP address for a second mobile entity. In response thereto, the GGSN receives the first IP address, which the GGSN declines for the second mobile entity and reserves for the first mobile entity. The GGSN requests an IP address for the second mobile entity a second time and receives a second IP address that is different from the first IP address.
