Abstract

Systems, apparatus, methods and computer-readable storage media that mitigate device power drain associated with stalled telemetry sessions are provided. In one embodiment, a first device includes a memory and a processor that executes executable components stored in the memory. The executable components include a communication component configured to receive a communication request from a second device via a telemetry communication link established between the first and second devices. The communication request can comprise a request for data. The executable components can also comprise a throughput monitoring component configured to monitor uplink throughput measuring successful transmission of the data by the first device to the second device via the telemetry communication link based on reception of the communication request. The communication component is configured to terminate the telemetry communication link based on the uplink throughput being below a threshold value.

a throughput monitoring component configured to monitor uplink throughput measuring successful transmission of the data by the device to the second device via the telemetry communication link, wherein the communication component is further configured to;

terminate the telemetry communication link based on the uplink throughput being below a threshold value for a defined period of time following reception of the communication request, wherein the defined period of time varies based on a type of telemetry session associated with the communication request, and wherein the uplink throughput represents a rate of successful message delivery over the telemetry communication link.

2. The device of claim 1, wherein the throughput monitoring component is configured to determine the uplink throughput based on a number of application data packets comprising the data that are transmitted by the device to the second device via the telemetry communication link per connection interval.

3. The device of claim 1, wherein the throughput monitoring component is configured to determine the uplink throughput based on time delays between successful transmissions of data packets comprising the data by the device to the second device via the telemetry communication link.

4. The device of claim 1, wherein the threshold value varies based on a type of the data.

5. The device of claim 1, wherein the threshold value varies based on a type of telemetry session associated with the communication request.

6. The device of claim 1, wherein the data comprises a first type of data and wherein the uplink throughput comprises first uplink throughput, and wherein the throughput monitoring component is configured to monitor the first uplink throughput independently from second uplink throughput measuring successful transmission of a second type of data by the device to the second device via the telemetry communication link.

7. The device of claim 1, wherein the transmission of the data comprises transmission of one or more data packets comprising the data, and wherein the throughput monitoring component is configured to determine the uplink throughput based on whether the communication component receives one or more acknowledgment messages from the second device that indicate the second device received the one or more data packets.

8. The device of claim 1, wherein the transmission of the data comprises transmission of one or more data packets comprising the data, and wherein the throughput monitoring component is configured to determine the uplink throughput based on timing of reception, by the communication component, of one or more acknowledgment messages from the second device that indicate the second device received the one or more data packets.
