Abstract

Some demonstrative embodiments include devices, systems and methods of quality of experience indication. For example, an apparatus may include a radio configured to communicate encoded multimedia data during a session over a wireless communication channel; and a Quality of Experience (QoE) estimator configured to determine at least one QoE indicator corresponding to the session, and to provide the QoE indicator to a session manager of the session, the QoE estimator configured to determine the QoE indicator based at least on a mean opinion score (MOS) corresponding to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel.

First claim

What is claimed is:

1. An apparatus comprising:
a transmitter configured to transmit encoded multimedia data during a session over a wireless communication channel; and
a transmit (Tx) Quality of Experience (QoE) estimator configured to determine at least one Tx QoE indicator corresponding to the session, and to provide the at least one Tx QoE indicator to a session manager of the session, the Tx QoE estimator configured to determine the at least one Tx QoE indicator based at least on a transmit-side mean opinion score (Tx MOS) corresponding to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel, the at least one Tx QoE indicator comprising a first Tx QoE indicator relative to a first threshold, and a second Tx QoE indicator relative to a second threshold, the second threshold higher her than the first threshold.

2. The apparatus of claim 1 , wherein the Tx QoE estimator is configured to determine the at least one Tx QoE indicator based on a Tx frame-per-second (FPS) parameter corresponding to the encoded multimedia data.

3. The apparatus of claim 1 comprising a Tx MOS estimator configured to determine the Tx MOS based on a throughput efficiency parameter corresponding to the encoded multimedia data.

4. The apparatus of claim 3 , wherein said throughput efficiency parameter comprises a goodput efficiency threshold.

5. The apparatus of claim 3 , wherein the Tx MOS estimator comprises said Tx QoE estimator.

6. The apparatus of claim 1 comprising said session manager configured to manage said session based at least on said at least one Tx QoE indicator.

7. The apparatus of claim 6 , wherein the session manager is configured to trigger, based at least on the at least one Tx QoE indicator, one or more operations selected from the group consisting of changing an encoding rate of the encoded multimedia data, and switching the session from the wireless communication channel to another wireless communication channel.

8. The apparatus of claim 1 , wherein the channel quality parameter comprises a channel congestion parameter corresponding to congestion on the wireless communication channel.

9. The apparatus of claim 8 comprising a congestion-flow estimator configured to determine the channel congestion parameter.

10. The apparatus of claim 1 , wherein the Tx QoE estimator is configured to determine the at least one Tx QoE indicator based at least on the channel quality parameter and a transmit-side non reference mean opinion score (Tx NRMOS) corresponding to the encoded multimedia data.

11. The apparatus of claim 1 , wherein said encoded multimedia data comprises encoded video data.

12. The apparatus of claim 1 comprising an encoder to generate the encoded multimedia data.

13. The apparatus of claim 1 comprising a memory, and a processor.

14. An apparatus comprising:
a receiver configured to receive encoded multimedia data during a session over a wireless communication channel; and
a receive (Rx) Quality of Experience (QoE) estimator configured to determine at least one Rx QoE indicator corresponding to the session, and to provide the at least one Rx QoE indicator to a session manager of the session, the Rx QoE estimator configured to determine the at least one Rx QoE indicator based at least on a receive-side mean opinion score (Rx MOS) corresponding to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel, the at least one Rx QoE indicator comprising a first Rx QoE indicator relative to a first threshold, and a second Rx QoE indicator relative to a second threshold, the second threshold higher than the first threshold.

15. The apparatus of claim 14 , wherein the Rx QoE estimator is configured to determine the at least one Rx QoE indicator based on a Rx frame-per-second (FPS) parameter corresponding to the received encoded multimedia data.

16. The apparatus of claim 14 comprising an Rx MOS estimator configured to determine the Rx MOS based on a throughput efficiency parameter corresponding to the encoded multimedia data.

17. The apparatus of claim 14 comprising said session manager configured to manage said session based at least on said at least one Rx QoE indicator.

18. The apparatus of claim 17 , wherein the session manager is configured to trigger, based at least on the at least Rx QoE indicator, one or more operations selected from the group consisting of requesting to change an encoding rate of the encoded multimedia data, and switching the session from the wireless communication channel to another wireless communication channel.

19. The apparatus of claim 14 comprising a decoder to decode the encoded multimedia data.

20. A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to cause a wireless device to:
transmit encoded multimedia data during a session over a wireless communication channel;
determine at least one transmit (Tx) Quality of Experience (QoE) indicator corresponding to the session, based at least on a transmit-side mean opinion score (Tx MOS) corresponding to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel, the at least one Tx QoE indicator comprising a first Tx QoE indicator relative to a first threshold, and a second Tx QoE indicator relative to a second threshold, the second threshold higher than the first threshold; and
provide the at least one Tx QoE indicator to a session manager of the session.

21. The product of claim 20 , wherein the instructions, when executed, cause the wireless device to determine the Tx MOS based on a throughput efficiency parameter corresponding to the encoded multimedia data.

22. A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to cause a wireless device to:
receive encoded multimedia data during a session over a wireless communication channel;
determine at least one receive (Rx) Quality of Experience (QoE) indicator corresponding to the session, based at least on a receive-side mean opinion score (Rx MOS) corresponding to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel, the at least one Rx QoE indicator comprising a first Rx QoE indicator relative to a first threshold, and a second Rx QoE indicator relative to a second threshold, the second threshold higher than the first threshold; and
provide the at least one Rx QoE indicator to a session manager of the session.

23. The product of claim 22 , wherein the instructions, when executed, cause the wireless device to determine the Rx MOS based on a throughput efficiency parameter corresponding to the encoded multimedia data.
