Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by a device a triggering message from an emergency call server responsive to an indication of an emergency condition at the device to trigger a tracking session to periodically collect and send tracking session data associated with the device to one or more servers, establishing the tracking session, separate from an emergency call session established between the device and the emergency call server, with the one or more servers, and sending, by the device to the one or more servers, the tracking session data collected during the tracking session by the device.

Systems and methods for emergency data communication

Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes: establishing an emergency call session between a wireless device and a public safety answering point (PSAP) server, via a first communication link, in response to an emergency indication provided by the wireless device; and sending location information indicating a location of the wireless device to the PSAP server via a second communication link, the location information indicating the location of the wireless device and being associated with the emergency call session; where the first communication link is different from the second communication link.

Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by an emergency call server an indication of an emergency condition at a device, determining whether the device is to be tracked based, at least in part, on the indication of the emergency condition, and transmitting a triggering message from the emergency call server, in response to a determination that the device is to be tracked, to trigger at the device a tracking session to cause the device to periodically collect and send tracking session data to one or more servers. The tracking session, established between the device and the one or more servers, is separate from an emergency call session established between the device and the emergency call server.

Disclosed are methods, devices, systems, apparatus, servers, media, and other implementations, including a method, performed at a first wireless device, for secure range determination that includes transmitting a first signed message at a first time instance, with the first signed message, including a first payload, configured to be received by a second wireless device at a second time instance, and receiving at a fourth time instance a verifiable acknowledgement message transmitted from the second wireless device at a third time instance in response to the first signed message. The method further includes verifying that the verifiable acknowledgement message originated from the second wireless device, and, responsive to a verification that the verifiable acknowledgement message originated from the second wireless device, transmitting a second signed message including a second payload with at least timing information for the first time instance and the fourth time instance.

Secure range determination protocol

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.

Dynamic subflow control for a multipath transport connection in a wireless communication network

Methods, systems and devices provide mechanisms and systems for efficiently delivering files over a broadcast system to mobile devices. Files for broadcast may be logically identified as belonging to a directory in a file system. A Broadcast Schedule Message may inform receiver devices of files that will be broadcast at a specified time, as well as describe the files. File may be transmitted in file delivery pipes, which may be of different bandwidth and data rates. Receiver devices configured according to the embodiments may make use of the broadcast schedule message to select files to be received based on the service or application with which the file is associated, and whether the file is new or an update to a previously received file. Receiver devices activate receiver circuitry to capture the files within their advertised broadcast window, and pass the received files to applications or services requesting the files.
