Method for predicting a level of QoE of an application intended to be run on a wireless user equipment
The present disclosure is directed toward a device and a method for evaluating a wireless link established between an access point and a user equipment. The device and method include determining a level of Quality of Experience of an application intended to be run on the user equipment using a mapping between a parameter representative of the QoE of the application under different wireless transmission conditions and sets of parameters representative of said different transmission conditions of the wireless link.
1. A method implemented by an access point (AP) the method comprising:
collecting, passively, a measurement for each parameter m a set of transmission condition parameters during each of a plurality of simulated transmission conditions;
receiving quality of experience (QoE) data from a station representative of an application running on the station performing a series of tasks during each of the plurality of simulated transmission conditions, wherein the plurality of simulated transmission conditions comprises variations in PhyRate, variations in medium availability due to Wi-Fi traffic, and variations in non-Wi-Fi traffic;
mapping the measurements of the set of transmission condition parameters with the QoE data;
selecting, based on the mapping, one parameter from the set of transmission condition parameters that is most relevant for predicting a QoE of the station.
2. The method of claim 1 , wherein the selecting is further based on only Wi-Fi traffic and Phy Rate variation simulated transmission conditions.
3. The method of claim 1 , wherein one of the series of tasks is measuring web page load times.
4. The method of claim 1 , wherein the QoE data is mean op1n10n score.
5. The method of claim 1 , wherein variations in the Phy Rate includes attenuations of 6, 12, 15, 18, 19, and 20 dBs in order to reduce the Phy Rate.
6. The method of claim 1 , wherein variations in non-WiFi traffic is created by a generated narrowband sinewave signal in order to block AP clear channel assessment, CCA.
7. An access point (AP) comprising:
a processor and a transceiver, the processor and transceiver configured to collect, passively, a measurement for each parameter in a set of transmission condition parameters during each of a plurality of simulated transmission conditions;
the processor and transceiver configured to receive quality of experience (QoE) data from a station representative of an application running on the station performing a series of tasks during each of the plurality of simulated transmission conditions, wherein the plurality of simulated transmission conditions comprises variations in PhyRate, variations in medium availability due to Wi-Fi traffic, and variations in non-Wi-Fi traffic;
the processor and transceiver configured to map the measurements of the set of transmission condition parameters with the QoE data;
the processor and transceiver configured to select, based on the mapping, one parameter from the set of transmission condition parameters that is most relevant for predicting a QoE of the station.
8. The AP of claim 7 , wherein the selecting is further based on only Wi-Fi traffic and Phy Rate variation simulated transmission conditions.
9. The AP of claim 7 , wherein one of the series of tasks is measuring web page load times.
10. The AP of claim 7 , wherein the QoE data is mean opinion score.
