Methods and apparatuses for rate adaptation of quality of service based application

1. A method of determining connection quality in a communication system, the method comprising:

measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and

determining the connection quality based on the plurality of packet delay times;

wherein the step of determining the connection quality comprises:

determining whether each of a number of consecutive packet delay times of the plurality of packet delay times is less than a second threshold; and wherein the method further comprises adjusting a congestion indicator to inactive if each of the number of consecutive packet delay times of the plurality of packet delay times is less than the second threshold.

2. The method of claim 1 , wherein the step of determining the connection quality comprises:

determining whether any of the plurality of packet delay times is greater than a first threshold; and the method further comprises adjusting a congestion indicator to active if any of the plurality of packet delay times is greater than the first threshold.

3. The method of claim 1 , wherein the plurality of packet delay times each comprise a difference in time between two packets being sent from a user equipment in the communication system.

4. The method of claim 1 , wherein the plurality of packet delay times each comprise a difference in time between two packets being received from a base station in the communication system.

5. The method of claim 1 , wherein the plurality of packet delay times each comprise a difference in time between one packet being received from an application layer and being sent to a base station of the communication system.

6. The method of claim 1 , further comprising:

reporting the connection quality to an application layer of a user equipment.

7. A system for determining connection quality in a communication system, the system comprising:

means for measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and

means for determining the connection quality based on the plurality of packet delay time;

11. The system of claim 7 , wherein the plurality of packet delay times each comprise a difference in time between one packet being received from an application layer and being sent to a base station of the communication system.

12. The system of claim 7 , further comprising:

means for reporting the connection quality to an application layer of a user equipment.

13. A computer program product comprising logic encoded on a non-transitory computer-readable tangible media for determining connection quality in a communication system, the logic comprising instructions for:

measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and

determining the connection quality based on the plurality of packet delay time;

wherein the instructions for determining the connection quality comprise instructions for:

determining whether each of a number of consecutive packet delay times of the plurality packet delay times is less than a second threshold; and wherein the computer program product further comprises instructions for adjusting a congestion indicator to inactive if each of the number of consecutive packet delay times of the plurality of packet delay times is less than the second threshold.

14. The computer program product of claim 13 , wherein the instructions for determining the connection quality comprise instructions for:

determining whether any of the plurality of packet delay times is greater than a first threshold; and the computer program product further comprises instructions for adjusting a congestion indicator to active if any of the plurality of packet delay times is greater than the first threshold.
