Method and apparatus for managing supplemental channel data rates

1. A method comprising:

determining latency values for each of a plurality of mobile devices;

determining fairness values for each of the plurality of mobile devices, wherein the latency values and the fairness values are at least partially based on QoS parameters or GoS classes, the fairness values corresponding to a fairness scheme; and

ranking the plurality of mobile devices based on the latency values and the fairness values to create a ranked list of mobile devices that can be employed to manage supplemental data rates for the plurality of mobile devices.

2. The method, as set forth in claim 1 , comprising establishing a supplemental channel for at least one of the plurality of mobile devices based on its position in the ranked listed of mobile devices.

3. The method, as set forth in claim 1 , comprising revoking a supplemental channel for at least one of the plurality of mobile devices based on its position in the ranked listed of mobile devices.

4. The method, as set forth in claim 1 , comprising adjusting a supplemental channel data rate of at least one of the plurality of mobile devices based on its position in the ranked listed of mobile devices.

5. The method, as set forth in claim 4 , comprising identifying an upgrade candidate and a downgrade candidate from the plurality of mobile devices, wherein adjusting the supplemental channel data rate comprises adjusting the supplemental channel data rate for the upgrade candidate, the downgrade candidate, or both.

6. The method, as set forth in claim 5 , wherein identifying the upgrade candidate comprises identifying a mobile device that was the highest ranked mobile device on the ranked listed of mobile devices and does not currently have the supplemental channel data rate at the maximum allowable rate.

7. The method, as set forth in claim 5 , wherein identifying the downgrade candidate comprises identifying a mobile device with an active supplemental channel that had the lowest ranking on the ranked list of mobile devices for a predetermined number of ranking iterations.

8. The method, as set forth in claim 1 , wherein ranking the plurality of mobile devices comprises calculating a ranking value for one of the mobile devices based on the fairness value for the mobile device and the latency value for the mobile device.

9. The method, as set forth in claim 1 , wherein ranking the plurality of mobile devices comprises calculating a ranking value for one of the mobile devices based on a faster-than-linear function of the latency value for the mobile device, a value representative of the GoS class of the mobile device, a predetermined maximum fairness value, a predetermined maximum latency value, and a priority class overlap parameter.

10. The method, as set forth in claim 1 , comprising:

measuring fundamental channel power for each of the plurality of mobile devices; and

determining a power adjustment factor for each of the plurality of mobile devices based on the measured fundamental channel power, wherein the latency values for each of the plurality of mobile devices are determined based on the power adjustment factors.

11. The method, as set forth in claim 1 , wherein the latency values and the fairness values comprises determining latency values and fairness values based on previous transmissions to each of the plurality of mobile devices.

12. The method, as set forth in claim 1 , wherein determining the latency values comprises adjusting the latency value if satisfying all of the users is not feasible.

13. A communications device comprising:

a module configured to determine latency values for each of a plurality of mobile devices;

a module configured to determine fairness values for each of the plurality of mobile devices, wherein the latency values and the fairness values are at least partially based on QoS parameters or GoS classes, the fairness values corresponding to a systemic fairness scheme; and

a module configured to rank the plurality of mobile devices based on the latency values and the fairness values to create a ranked list of mobile devices.

14. The communication device, as set forth in claim 13 , wherein the communications device comprises:

a module configured to measure fundamental channel power for each of the plurality of mobile devices; and

a module configured to determine a power adjustment factor for each of the plurality of mobile devices based on the measured fundamental channel power, wherein the latency values for each of the plurality of mobile devices are determined based on the power adjustment factors.

15. The communication device, as set forth in claim 13 , wherein the communications device comprises a module configured to adjust a supplemental channel data rate of one of the plurality of mobile devices based on its position in the ranked listed of mobile devices.

16. The communication device, as set forth in claim 13 , wherein the communication device comprises a wireless telephone base station.

17. A wireless telephone transmitter comprising:

a module configured to determine a power adjustment for each of a plurality of mobile devices based on the channel conditions for each of the mobile devices;

a module configured to determine an indicator of a satisfaction level of each of the plurality of wireless devices;

a module configured to determine an indicator of how fairly the wireless telephone transmitter is allocating supplemental channel data rates, the fairness indicator corresponding to a fairness scheme; and

a module configured to rank the plurality of wireless devices based at least partially on the power adjustment, the fairness indicator, and the satisfaction indicator.

18. The wireless telephone transmitter, as set forth in claim 17 , comprising a module configured to allocate supplemental channel data rates to one or more of the plurality of wireless device based on the rank of the wireless device.
