Method of collection of quality statistics and corresponding method of management of collection of quality statistics

1. A method of collection of quality statistics, wherein the method comprises the following steps, implemented by a quality statistics collecting device, referred to as first device:

reception of a collection mode signal comprising an information representative of a mode of collection of quality statistics, so-called requested mode, said requested mode having at least two possible values comprising a first mode and a second mode;

if the requested mode is the first mode, entering in the first mode;

if the requested mode is the second mode, entering in the second mode;

in the first mode, connection to a test stream upon reception of a request for connection signal comprising a request for connection to said test stream;

in the second mode, automatic connection to a test stream whenever resources of said first device needed for said collection of quality statistics are available;

collection of quality statistics when said collection of quality statistics has been enabled by reception of a quality statistics collection enable signal enabling said collection of quality statistics and when said first device is connected to a stream.

2. The method according to claim 1 , wherein said test stream of said second mode is a parameter that is configurable by a second device different than said first device.

3. The method according to claim 1 , wherein said resources of said first device needed for said collection of quality statistics are considered to be available when a connection to said test stream and said collection of quality statistics on said test stream does not impact the quality of service rendering by said first device.

4. The method according to claim 1 , wherein said resources of said first device needed for said collection of quality statistics are considered to be available when said first device is not connected to a stream coming from a Wide Area Network whereby a distinction between a stream coming from the Wide Area Network and a stream not coming from the Wide Area Network is made by comparing a source IP address of the stream with the IP address of said first device.

5. The method according to claim 1 , wherein the said resources of said first device needed for said collection of quality statistics are made available in a stand-by state of said first device.

6. The method according to claim 1 , wherein said quality statistics are classified according to a type of stream for which said quality statistics apply.

7. The method according to claim 6 wherein said type of stream comprises a test type stream and a user-selected type stream.

8. The method according to claim 1 , wherein said quality statistics belong to a set comprising quality of service and quality of experience.

9. The method according to claim 1 , wherein said quality statistics concern audio and video type services.

10. A method of management of collection of quality statistics, wherein the method comprises following steps, implemented by a quality statistics management means:

sending of a collection mode signal to at least one quality statistics collecting device comprising an information representative of a mode of collection of quality statistics, so-called requested mode, the said requested mode having at least two possible values comprising a first mode and a second mode;

in the first mode, sending of a request for connection signal to said at least one quality statistics collecting device comprising a request for connection to a test stream;

wherein in the first mode, a connection of said at least one quality statistics collecting device to a test stream is made upon reception of the request for connection signal; and wherein in the second mode, a connection of said at least one quality statistics collecting device to the test stream is automatically made whenever resources of said at least one quality statistics collecting device needed for said collection of quality statistics are available.

11. The method according to claim 10 , wherein the method comprises a step of reception of collected quality statistics from said at least one quality statistics collecting device.

12. The method according to claim 10 , wherein the method comprises a step of sending of information representative of a collection interval, to said at least one quality statistics collecting device.

13. The method according to claim 10 , wherein a signal requesting a connection to a test stream is sent to said at least one quality statistics collecting device.

14. The method according to claim 10 , wherein said quality statistics are classified according to a type of stream for which said quality statistics apply.

15. The method according to claim 14 , wherein said type of stream comprises a test type stream and a user-selected type stream.
