Abstract: Systems and methods for routing communications received via a PTSN are disclosed. A communication session server facilitates communication sessions between a first computing device, a second computing device and a public service accessible via a PSTN. The first computing device establishes a communication session with the communication session server using a first communication mode. The second computing device establishes a communication session with the public service using a second communication mode and a communication session with the communication session server using the first communication mode. Communications received by the second computing device from the public service via the second communication mode are routed to the communication session server via the first communication mode. The communication session server then sends the received communications to the first computing device using the first communication mode.

Abstract: An initiating device receives an initiation of a packet-based call to a service. The initiating device may detect a failure of the packet-based call and determine whether a proxy device is in proximity to the initiating device. The proxy device may be cellular-enabled and capable of communicating with a cellular network. Upon a determination that the proxy device is in proximity to the initiating device, the initiating device instructs the proxy device to communicate with the service using the cellular network. The initiating device then communicates with the service via the proxy device and the cellular network.

Abstract: Methods and apparatus in a wireless network that allow devices, such as client devices and access points (APs), having software defined radios (SDRs) to change operating behavior depending on network RF environment conditions are disclosed. The devices may be instructed to operate according to differently defined behavior profiles that may be chosen based on RF environment conditions. The profiles may be stored in a database. A particular profile may be obtained from the database for one or more devices based on an interference level within an RF environment of the devices. The profiles may be implemented to change device operating behavior so that interference is reduced or minimized in higher levels of interference. The profiles may also be implemented to change device behavior so that interference is reduced in lower levels of interference while also freeing up resources for more efficient use in network during lower levels of interference.

Abstract: Data traffic routing and/or transmission parameter adaption decisions are made at a sending node by considering error patterns of one or more possible receiving nodes at the bit level. Data traffic routing and/or transmission parameter adaption decisions may be used to preemptively prevent data errors from occurring as data traffic is transmit by a sending node. The error pattern information may include information on numbers of bit errors in a code word or information on relative randomness or burstiness of bit error patterns at the one or more possible receiving nodes. The collaboratively shared error pattern information may be determined and updated over time intervals or upon selected conditions occurring. In one embodiment, a next hop node may be determined using bit error patterns of neighbor nodes. In another embodiment, transmission parameter adaption or channel selection may be determined using bit error patterns.
