  • Publication number: 20130083679
    Abstract: Methods and devices for processing and retransmitting highway communication system transmissions include determining a reliability of a received message and including an indication of the reliability in retransmitted transmissions. Reliability of received messages may be based on a signal strength of the received peer transmission, comparison of the signal strength to a distance to the transmitter based on message contents, the age of the received message, the signal quality of the received message, and other parameters. An indication of the determined reliability may be included in retransmissions of the message to enable other vehicles and receiver units in the highway communication system to benefit from the reliability determination. Message reliability may be used as part of prioritizing messages for processing. Messages may be processed according to priority so that high priority messages are processed before lower priority messages.

  • Publication number: 20130077501
    Abstract: A multipath transport protocol such as multipath TCP can utilize metrics such as a wireless link condition corresponding to one or more paths as a parameter for controlling a dynamic allocation of data and control signaling over respective paths. Fault-tolerant control can enable retransmissions of packets already sent on a poor path, onto a good path. Further, the feedback, the retransmissions, and other control signaling can be provided on a separate subflow or on a UDP overlay. In this way, a multipath TCP connection can be more reliable and efficient as flow control and data flow are enhanced.

  • Patent number: 8385240
    Abstract: A device chooses to use any one of a number of nodes with wireless wide area network (WWAN) modems, depending on whether utilization of one of the nodes will mitigate the power consumption of the device. The choice might also be a function of an energy level of the nodes. The choice can also be based on a link performance indicator. The chosen node is selected as a WWAN modem for communication and utilizes the identity of the device for application data services being supported in this mode.

  • Patent number: 8379552
    Abstract: An arrangement is provided for adapting the output bit rate of a multimedia source to the bandwidth available in a wireless network. Depending on the value of the available network idle time, at least a portion of the available network idle time may be used by the source to increase its output bit rate so that the network bandwidth may be more efficiently utilized. If the effective throughput of the network after the increase of source output bit rate drops significantly, the source may reduce its output bit rate until the effective throughput returns to the level before the source output bit rate increase. Additionally, packet delay and queue jitter information may be collected and used for queue rate adaptation as well as bandwidth adaptation.

  • Patent number: 8279794
    Abstract: Mobile communication devices and wireless network device each can participate in, or solely provide, opportunistic data forwarding in a wireless network such as a wireless local area network or radio access network. A supporting node receives wireless communication between a transmitting node and a receiving node comprising packet data units (PDUs). The receiving node communicates to the transmitting node that one or more portions of the communication were not received, which is overheard by the supporting node. The supporting node can have sufficient over-the-air (OTA) allocation in its transmit opportunity to relay the failed portions to the receiving node. Thereby, techniques such as more robust error encoding, longer transmit allocations, etc., that would reduce the effective data throughput for OTA resources are avoided while providing an ability to more rapidly adapt to a changing channel state.

  • Publication number: 20120155386
    Abstract: Systems, methods, devices, and computer program products are described for the reduction of signaling to the core network of a wireless communications system. In one example, a proxy receives a request message transmitted from a mobile device to the core network. The proxy traps the request message to prevent it from being forwarded to the core network. The proxy generates a request accept message in response to the trapped request message, the request accept message spoofing a core network response to the request message. The proxy transmits the request accept message to the mobile device.
