Determining quality of experience for communication sessions

A computer program product comprising a computer readable medium having a plurality of instructions stored thereon, which, when executed by a processor, cause the processor to perform operations including:

• determining a plurality of intrusive quality of experience scores associated with a plurality of intrusive audio transmission samples during a communication session between a first user device and a second user device over a network, wherein the network includes a controllable environment configured to vary network jitter values in increment, wherein the plurality of intrusive quality of experience scores are determined for a respective plurality of different network jitter values;
• determining a plurality of non-intrusive quality of experience scores associated with a plurality of non-intrusive audio transmission samples, wherein each non-intrusive audio transmission sample of the plurality of non-intrusive audio transmission samples is obtained at a same time frame during the communication session as a corresponding intrusive audio transmission sample of the plurality of intrusive audio transmission samples and wherein the plurality of non-intrusive quality of experience scores are determined for the respective plurality of different network jitter values;
• deriving a quality of experience coefficient based upon a relationship between the plurality of intrusive quality of experience scores and the plurality of non-intrusive quality of experience scores based on an approximation of a non-linear regression model;
• determining a non-intrusive quality of experience score associated with an audio transmission;
• applying the quality of experience coefficient to the non-intrusive quality of experience score, resulting in a corrected non-intrusive quality of experience score associated with the audio transmission between a first user device and a second user device;
• wherein the computer readable medium is not transitory per se.

A computing system comprising:

• a processor and a memory module coupled with the processor, the processor being configured for:
• determining a plurality of intrusive quality of experience scores associated with a plurality of intrusive audio transmission samples during a communication session between a first user device and a second user device over a network, wherein the network includes a controllable environment configured to vary network jitter values in increment, wherein the plurality of intrusive quality of experience scores are determined for a respective plurality of different network jitter values;
• determining a plurality of non-intrusive quality of experience scores associated with a plurality of non-intrusive audio transmission samples, wherein each non-intrusive audio transmission sample of the plurality of non-intrusive audio transmission samples is obtained at a same time frame during the communication session as a corresponding intrusive audio transmission sample of the plurality of intrusive audio transmission samples and wherein the plurality of non-intrusive quality of experience scores are determined for the respective plurality of different network jitter values;
• deriving a quality of experience coefficient based upon a relationship between the plurality of intrusive quality of experience scores and the plurality of non-intrusive quality of experience scores based on an approximation of a non-linear regression model;
• determining a non-intrusive quality of experience score associated with an audio transmission;
• and
• applying the quality of experience coefficient to the non-intrusive quality of experience score, resulting in a corrected non-intrusive quality of experience score associated with the audio transmission between a first user device and a second user device.
