Abstract

A method, system and apparatus for monitoring error correction data are provided. The method comprises receiving an authorization request defining a media session between an AF server and a mobile device from the AF server. The authorization request contains a media packet flow identifier and a corresponding forward error correction (FEC) packet flow identifier. The method includes deploying policy rules for the media session to a gateway server, the policy rules including the media packet flow identifier and the FEC packet flow identifier; receiving periodic reports from the gateway server, the reports including packet counts for each of the media packet flow and the FEC packet flow; determining whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold; and when the determination is affirmative, sending an action request to the AF server.

Claims

1. A method in a policy server having a processor, a memory and a network interface connected to a gateway server and an application function (AF) server, the method comprising:

receiving an authorization request defining a media session between the AF server and a mobile device at the processor from the AF server via the network interface;

the authorization request containing a media packet flow identifier and a corresponding forward error correction (FEC) packet flow identifier;

deploying policy rules for the media session from the processor to the gateway server via the network interface, the policy rules including the media packet flow identifier and the FEC packet flow identifier;

receiving periodic reports at the processor from the gateway via the network interface, the reports including packet counts for each of the media packet flow and the FEC packet flow;

determining, at the processor, whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold; and

when the determination is affirmative, sending an action request to the AF server via the network interface.

2. The method of claim 1, further comprising:

prior to deploying the policy rules, retrieving a policy corresponding to the mobile device from the memory, and evaluating the policy to determine whether the media session is permitted.

3. The method of claim 1, the policy rules including a reporting period specifying the period of time between the periodic reports.

4. The method of claim 1, wherein the determining includes:

generating a bandwidth value based on the periodic reports and the period of time elapsed between the periodic reports; and

comparing the bandwidth value to the threshold.

5. The method of claim 1, wherein the authorization request includes an FEC algorithm identifier.

6. The method of claim 5, wherein the determining includes:

retrieving an overhead value corresponding to the FEC algorithm identifier from the memory;

generating a bandwidth value based on the overhead value and the periodic reports; and

comparing the bandwidth value to the threshold.

7. The method of claim 1, the action request containing an indication that the FEC packet flow has exceeded the threshold.

8. A policy server, comprising:

a memory;

a network interface connected to a gateway server and an application function (AF) server; and

a processor interconnected with the memory and the network interface, the processor configured to;

receive an authorization request defining a media session between the AF server and a mobile device from the AF server via the network interface;

the authorization request containing a media packet flow identifier and a corresponding forward error correction (FEC) packet flow identifier;

deploy policy rules for the media session to the gateway server via the network interface, the policy rules including the media packet flow identifier and the FEC packet flow identifier;

receive periodic reports from the gateway via the network interface, the reports including packet counts for each of the media packet flow and the FEC packet flow;

determine whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold; and

when the determination is affirmative, send an action request to the AF server via the network interface.

9. The policy server of claim 8, further comprising:

prior to deploying the policy rules, retrieving a policy corresponding to the mobile device from the memory, and evaluating the policy to determine whether the media session is permitted.

10. The policy server of claim 8, the policy rules including a reporting period specifying the period of time between the periodic reports.

11. The policy server of claim 8, the processor further configured to determine whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold by:

generating a bandwidth value based on the periodic reports and the period of time elapsed between the periodic reports; and

comparing the bandwidth value to the threshold.

12. The policy server of claim 8, wherein the authorization request includes an FEC algorithm identifier.

13. The policy server of claim 12, the processor further configured to determine whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold by:

retrieving an overhead value corresponding to the FEC algorithm identifier from the memory;

generating a bandwidth value based on the overhead value and the periodic reports; and

comparing the bandwidth value to the threshold.

14. The policy server of claim 8, the action request containing an indication that the FEC packet flow has exceeded the threshold.

15. A non-transitory computer readable medium storing a plurality of computer-readable instructions executable by a processor of a policy server having a memory and a network interface interconnected with the processor, for implementing a method comprising:

receiving an authorization request defining a media session between the AF server and a mobile device at the processor from the AF server via the network interface;

the authorization request containing a media packet flow identifier and a corresponding forward error correction (FEC) packet flow identifier;

deploying policy rules for the media session from the processor to the gateway server via the network interface, the policy rules including the media packet flow identifier and the FEC packet flow identifier;

receiving periodic reports at the processor from the gateway via the network interface, the reports including packet counts for each of the media packet flow and the FEC packet flow;

determining, at the processor, whether bandwidth consumed by the FEC packet flow exceeds a predetermined threshold; and

when the determination is affirmative, sending an action request to the AF server via the network interface.

16. The non-transitory computer readable medium of claim 15, the method further comprising:

17. The non-transitory computer readable medium of claim 15, the policy rules including a reporting period specifying the period of time between the periodic reports.

18. The non-transitory computer readable medium of claim 15, wherein the determining includes:

generating a bandwidth value based on the periodic reports and the period of time elapsed between the periodic reports; and

comparing the bandwidth value to the threshold.

19. The non-transitory computer readable medium of claim 15, wherein the authorization request includes an FEC algorithm identifier.

20. The non-transitory computer readable medium of claim 19, wherein the determining includes:

retrieving an overhead value corresponding to the FEC algorithm identifier from the memory;

generating a bandwidth value based on the overhead value and the periodic reports; and

comparing the bandwidth value to the threshold.

21. The non-transitory computer readable medium of claim 15, the action request containing an indication that the FEC packet flow has exceeded the threshold.
