Abstract

A system and method for determining the quality of service in wireless data network by a plurality of mobile devices is provided. In one embodiment, the method includes presenting to a user a plurality of reference content items, for each content item, receiving a reference content item rating indicative of a quality rating provided by the user, wirelessly transmitting a test content item to the mobile device, presenting the transmitted test content item to the user; receiving a test content item rating provided by the user, wherein at least some of the plurality of reference content items comprise content items of known and differing quality, normalizing the test content item rating based on the reference content rating received to provide a normalized test content item rating; and outputting a quality of service performance metric based on the normalized test content item rating.

Claims

1. A method of determining a performance metric provided by a plurality of mobile devices that communicate over a wireless data network, comprising:

(a) transmitting from a content server a plurality of reference content items of differing content quality to be viewed and rated;

(b) for the plurality of reference content items transmitted, receiving by the content server a reference content item rating indicative of a quality rating provided by a mobile device user;

(c) validating the received reference content item rating against a range of ratings considered valid for the reference content item;

(d) transmitting a test content item via the wireless data network to be viewed and rated at the mobile device after validating the reference content item ratings;

(e) receiving by the content server a test content item rating indicative of a quality rating for the test content item provided by the user;

performing (a)-(e) for plurality of additional mobile devices;

normalizing the test content item ratings received from the mobile devices based on the reference content ratings received from the respective mobile devices; and

outputting normalized performance metrics for the plurality of mobile devices.

2. The method according to claim 1, further comprising determining whether the reference content item ratings received by each of the plurality of mobile devices are valid;

and

discarding the test content item rating from a first mobile device if the reference content item ratings received by the first mobile device are not valid.

3. The method according to claim 1, wherein at least some of the plurality of reference content items comprise content items having a predetermined quality degradation.

4. The method according to claim 3, wherein at least some of the plurality of reference content items include artifacts.

5. The method according to claim 1, wherein the test content item and the plurality of reference content items comprise video content.

6. The method according to claim 1, wherein the test content item and the plurality of reference content items comprise web content.

7. The method according to claim 1, wherein the test content item and the plurality of reference content items comprise game content.

8. The method according to claim 1, wherein the test content item and the plurality of reference content items comprise audio content.

9. The method according to claim 1, further comprising with each of the plurality of mobile devices, transmitting data representing the user input indicative of the quality rating of the test content item and of the plurality of reference content items to a remote device;

and

wherein said normalizing is performed by said remote device.

10. The method according to claim 1, wherein the test content item is received as streaming content.

11. The method according to claim 1, wherein said normalizing comprises dividing data of the test content item rating by data of the plurality of reference content item ratings.

12. The method according to claim 1, further comprising with each mobile device, transmitting network information determined for the network during reception of the test content item.

13. The method according to claim 1, further comprising with each of the plurality of mobile devices, transmitting location information of the mobile device during reception of the test content item.

14. A computer program product stored in one or more non-transitory tangible computer readable medium having executable instructions to determine a performance metric of a mobile device that communicates over a wireless data network, comprising:

a code segment to transmit a plurality of reference content items of differing content quality to be viewed and rated to a plurality of mobile devices via a communication path that includes the wireless data network;

a code segment to receive reference content ratings from the plurality of mobile devices;

a code segment to validate each of the plurality of reference content items against a range of ratings considered valid for the reference content item;

a code segment to transmit a test content item after the reference content item is validated;

a code segment to receive a test content rating indicative of a quality rating of the test content item;

a code segment to normalize the test content ratings received from the mobile devices based on the plurality of reference content ratings from the respective mobile devices; and

a code segment to output normalized performance metrics for the plurality of mobile devices.

15. The computer program product according to claim 14, further comprising a code segment executable to determine whether the reference content ratings received from each of the plurality of mobile devices is valid.

16. The computer program product according to claim 14, further comprising a code segment executable to receive and store in a memory for each mobile device, network information collected by each of the plurality of mobile devices during receipt of the test content item.

17. The computer program product according to claim 14, further comprising a code segment executable to store in a memory, for each mobile device, location information and time information during receipt of the test content item.

18. The computer program product according to claim 14, wherein said code segment to normalize the test content rating is configured to divide data of the test content item rating by data of the plurality of reference content item ratings.

19. A method of determining the quality of service provided by a plurality of mobile devices communicating over a wireless data network, comprising:

transmitting a plurality of reference content items to a plurality of mobile devices;

receiving a plurality of reference content ratings from the plurality of mobile devices;

wherein each of the plurality of reference content ratings corresponds to a different reference content item;

wherein at least some of the plurality of reference content items comprise content items of differing and predetermined quality;

validating the received reference content item ratings against a range of ratings considered valid for the reference content item;

transmitting a test content item to each of the plurality of mobile devices via the wireless data network after validating the reference content item ratings;

receiving a test content rating indicative of a quality rating for the test content item from each of the plurality of mobile devices;

normalizing the test content rating based on the plurality of reference content ratings for each of the plurality of mobile devices; and

outputting one or more performance metrics based on the normalized test content rating of each of the plurality of mobile devices.

20. The method according to claim 19, further comprising determining whether the reference content ratings received from each of the plurality of mobile devices are valid;

and

discarding the test content rating received from the device if reference content ratings received from the mobile device are not valid.
