  • Patent number: 8195187
    Abstract: In a radio access network, multiple radio network controllers are connected to several radio nodes using a network. The interconnected radio network controllers and radio nodes are addressable, and, therefore, each radio network controller can communicate directly with each radio node and visa versa. The radio access network can be configured to avoid active handoffs between radio network controllers by maintaining a traffic channel set up between an access terminal and a radio network controller even as the flow.

  • Patent number: 8160020
    Abstract: In connection with a mobile wireless subnetwork having multiple radio network controllers and multiple radio nodes, a session established for an access terminal is associated with a serving radio network controller. The association is maintained as the access terminal moves from the coverage area of one radio node to the coverage area of another radio node within the same subnetwork. Access channel packets are routed from an access terminal having an existing session to the serving radio network controller by determining the IP address of the serving radio network controller using a session identifier.

  • Patent number: 7934001
    Abstract: Techniques for network-initiated session recovery are described. A relationship is maintained between two identifiers both associated with a session between a first device and an access terminal in a wireless network. The first identifier is associated with the first device, and the second identifier is associated with a second device in communication with the first device. After a breach of the session, communications associated with the session are preserved based on the relationship between the first and second identifiers.
