  • Patent number: 8699415
    Abstract: A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

  • Patent number: 8638752
    Abstract: When a mobile device moves from a first QoS-aware system to a second QoS-aware system, QoS flows may or may not be moved properly. To deal with this, the mobile device requests de-allocation of flows in the second QoS-aware system, and then initiates reservation of flows in the second QoS-aware system. After this, the mobile device will know for certain which QoS flows exist in the second QoS-aware system and can behave accordingly.

  • Patent number: 8548510
    Abstract: A method and apparatus are provided wherein a mobile device operates some of the time on a first network and some of the time on a second network, and wherein while handling traffic of a defined type over the first network, the mobile device selectively tunes away to the second network to see if there are any messages. The method and apparatus allow a mobile device with a single transceiver to receive CMAS alerts transmitted over a 1xRTT network while minimizing disruption to ongoing delay sensitive data applications operating on a 1xEV-DO network.
