US 12,628,028 B2 · Method and system for traffic engineering supporting real-time applications

Abstract

Embodiments are disclosed for traffic engineering in support of real-time applications. A user equipment (UE) can detect a real-time application running on the UE, assess a link health corresponding to the real-time application, and transmit a payload including the link health to a peer device via WiFi communications. To detect the real-time application, the UE can receive traffic symptoms or application indications, and monitor corresponding traffic flows. To assess the link health, the UE can receive link quality metrics of a link corresponding to the link health, and determine an intra basic service set (BSS) clear channel assessment (CCA) percentage. The UE can initiate a Rapport session with the peer device, activate a keep-alive timer, and transmit updated information to the peer device according to the keep-alive timer.

Dependent claims

A wireless device comprising:

a transceiver;
and
a processor communicatively coupled to the transceiver, configured to:
detect a real-time application running on the wireless device;
assess a link health of a link corresponding to the real-time application, wherein the link is associated with a WiFi channel;
subsequent to the assessment, monitor a traffic rate of the real-time application and a traffic rate of a non-real-time application running on the wireless device;
determine that the traffic rate of the non-real-time application satisfies a threshold;
and
subsequent to the determination, dequeue an access category corresponding to the real-time application at a greater rate than an access category corresponding to the non-real-time application.

6 more elements

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a wireless device, cause the wireless device to perform operations, the operations comprising:

detecting a real-time application running on the wireless device;
assessing a link health of a link corresponding to the real-time application, wherein the link is associated with a WiFi channel;
subsequent to the assessment, monitoring a traffic rate of the real-time application and a traffic rate of a non-real-time application running on the wireless device;
determining that the traffic rate of the non-real-time application satisfies a threshold;
and
subsequent to the determination, dequeuing an access category corresponding to the real-time application at a greater rate than an access category corresponding to the non-real-time application.
