Abstract

An example method includes: setting a timeout value for retrying communication requests during a communications session with a target device; sending a test request to the target device; measuring a response time between the test request and a response to the test request received from the target device; determining a specific timeout value for the target device based on the response time; and updating the timeout value with the specific timeout value for the target device and continuing the communications session with the specific timeout value for retrying communication requests for the target device.

  2. 2 . The method of claim 1 , wherein sending the test request comprises: sending a plurality of test requests and receiving a plurality of responses at respective response times; and selecting a slowest response time of the respective response times for determining the specific timeout value.
  3. 3 . The method of claim 2 , wherein each test request of the plurality of test requests includes different parameters.
  4. 4 . The method of claim 3 , wherein the different parameters comprise a marked priority level and an unmarked priority level.
  5. 5 . The method of claim 3 , wherein the different parameters comprise different communications protocols.
  6. 6 . The method of claim 1 , wherein the specific timeout value is associated with one or more parameters of the test request.
  7. 7 . The method of claim 1 , wherein determining the specific timeout value comprises adding a buffer time to the response time to obtain a base timeout value.
  8. 8 . The method of claim 7 , wherein determining the specific timeout value further comprises applying a complexity weighting to the base timeout value, the complexity weighting associated with a communications protocol.
  9. 9 . The method of claim 1 , further comprising monitoring for an update condition to update the timeout value; wherein the update condition comprises one or more of: expiry of a predefined update period; and detection of a change in a network quality of service parameter.
  10. 10 . The method of claim 1 , further comprising retaining the timeout value when the response to the test request is not received within the timeout value.
  11. 11 . A device comprising: a communications interface configured for communications with a target device; a controller interconnected with the communications interface, the controller configured to: set a timeout value for retrying communication requests during the communications with the target device; send a test request to the target device; measure a response time between the test request and a response to the test request received from the target device; determine a specific timeout value for the target device based on the response time; and update the timeout value with the specific timeout value for the target device and continue the communications with the specific timeout value configured for retrying communication requests for the target device.
  12. 12 . The device of claim 11 , wherein to send the test request, the controller is configured to: send a plurality of test requests and receiving a plurality of responses at respective response times; and select a slowest response time of the respective response times for determining the specific timeout value.

Description

BACKGROUND During wireless communications, various network and endpoint device conditions may cause variations in the speed of communications. In some cases, the communications link between two endpoint devices may be experience an issue requiring a recovery operation to recover. Prior to initiating the recovery operation, the devices may wait for a default timeout period to elapse to ensure that communications are not simply slow. The default timeout period may be set to be sufficiently long to cover such slow communications due to the network and endpoint device conditions. However, such a long default timeout period results in delayed recovery operations and may result in dropped packets or communications.
