Abstract

A bidirectional notification system and method for improving the quality of media in a packet switched transmission network are disclosed. The end user of the packet switched network detects impairments in the media and initiates a pull message to a media quality control system disposed between the end user and the packet switched transmission network. The pull message causes the detection subsystem of the media quality control system to improve the media flow in order to mitigate the impairment detected by the end user. The detection subsystem of the media quality control system may also detect impairments in the media without input from the end user and launch a push message in response to the detection of the impairment. The push message announcing the impairment is provided to the end user with either an audio or visual message.

Claims

1. A notification method for improving the quality of a media flow in a packet switched transmission network, comprising:

detection by the end user of an impairment in the media received by the end user from the packet switched transmission network;

initiation by the end user of a pull message to a media quality control system disposed between the end user and the packet switched transmission network; and

causing the media quality control system to improve the media flow in response to the pull message, in order to mitigate the impairment detected by the end user, wherein the end user initiates a pull message via a hardware button.

2. A notification method according to claim 1, further comprising:

detection by the media quality control system of an impairment in the media provided to the end user;

launching a push message by the media quality control system in response to the detection of the impairment; and

providing to the end user the push message announcing the impairment.

3. A notification method according to claim 2 where the media quality control system includes a path control system.

4. A notification method according to claim 2 where the media quality control system includes a system for changing codecs.

5. A notification method according to claim 2 where the media quality control system includes a system for echo cancellation.

6. A notification method according to claim 2, wherein the user is provided with either an audio or visual push message.

7. A notification method according to claim 6, wherein the user is provided with the visual push message and the visual push message is displayed on a display and includes text announcing the impairment and describing the status of the impairment.

8. A notification method according to claim 6, wherein the user is provided with the audio message.

9. A notification method according to claim 2, wherein the end user is provided with a push message acknowledging the receipt of the end user initiated pull message.

10. A notification method according to claim 2 wherein the detection by the media quality control system of an impairment in the media provided to the end user occurs in response to the pull message.

11. A notification method according to claim 1, wherein the media quality control system includes a detection subsystem and causes its detection subsystem to react in response to the pull message.

12. A notification method according to claim 1 where the media quality control system includes a path control system.

13. A notification method according to claim 1 where the media quality control system includes a system for changing codecs.

14. A notification method according to claim 1 where the media quality control system includes a system for echo cancellation.

15. A notification method according to claim 1, wherein the end user is provided with a push message acknowledging the receipt of the end user initiated pull message.

16. A notification method according to claim 15 where the media quality control system includes a path control system.

17. A notification method according to claim 15 where the media quality control system includes a system for changing codecs.

18. A notification method according to claim 15 where the media quality control system includes a system for echo cancellation.
