Abstract

In a method for allocating a system resource to subscribers of a wireless communication system a resource sensitivity indicator is determined for a system resource allocated by the wireless communication system for each of a first subscriber and a second subscriber. The system resource may include a level of service, a channel frequency, or a data rate. Next, an inefficient allocation of the system resource detected. One of the first and second subscribers having a lower resource sensitivity indicator is selected. Finally, an allocation of the system resource is changed for the selected subscriber unit to increase the efficiency of the allocation of the system resource.

Claims

1. A method for allocating a system resource to subscribers of a wireless communication system, the method comprising the steps of:

for each of a first subscriber and a second subscriber, determining a resource sensitivity indicator for a system resource allocated by the wireless communication system;

detecting an inefficient allocation of the system resource wherein an alternate allocation comes closer to fulfilling requests for allocation of a requested system resource than a present allocation; and

changing an allocation of the system resource to the one of the first and second subscribers having a lower resource sensitivity indicator to increase the efficiency of system resource allocation.

2. The method for allocating a system resource of a wireless communication system according to claim 1 wherein the system resource includes a channel having a selected transmission frequency.

3. The method for allocating a system resource of a wireless communication system according to claim 1 wherein the system resource includes a data transmission rate.

4. The method for allocating a system resource of a wireless communication system according to claim 1 wherein the system resource includes a data transmission quality.

5. The method for allocating a system resource of a wireless communication system according to claim 1 wherein the step of determining a resource sensitivity indicator for a system resource allocated by the wireless communication system further includes determining a preference for a first system resource over a second system resource.

6. The method for allocating a system resource of a wireless communication system according to claim 5 wherein the step of determining a preference for a first system resource over a second system resource further includes determining a magnitude of a preference of a first system resource over a second system resource.

7. The method for allocating a system resource of a wireless communication system according to claim 5 wherein the step of determining a preference for a first system resource over a second system resource further includes determining a preference of a channel having a first transmission frequency over a channel having a second transmission frequency.

8. The method for allocating a system resource of a wireless communication system according to claim 1 wherein the step of changing an allocation of the system resource to the one of the first and second subscribers having a lower resource sensitivity indicator to increase the efficiency of system resource allocation further includes changing an allocation of a channel frequency to the one of the first and second subscribers having a lower frequency resource sensitivity indicator to increase the efficiency of the allocation of channel frequencies.

9. A system for allocating a system resource to subscribers of a wireless communication system comprising:

means for determining a resource sensitivity indicator for a system resource allocated by the wireless communication system for each of a first subscriber unit and a second subscriber unit;

means for detecting an inefficient allocation of the system resource wherein an alternate allocation comes closer to fulfilling requests for allocation of a requested system resource than a present allocation; and

means for changing an allocation of the system resource to the one of the first and second subscriber units having a lower resource sensitivity indicator to increase the efficiency of system resource allocation.

10. The system for allocating a system resource of a wireless communication system according to claim 9 wherein the system resource includes a channel having a selected transmission frequency.

11. The system for allocating a system resource of a wireless communication system according to claim 9 wherein the system resource includes a data transmission rate.

12. The system for allocating a system resource of a wireless communication system according to claim 9 wherein the system resource includes a data transmission quality.

13. The system for allocating a system resource of a wireless communication system according to claim 9 wherein the means for determining a resource sensitivity indicator for a system resource allocated by the wireless communication system further includes means for determining a preference for a first system resource over a second system resource.

14. The system for allocating a system resource of a wireless communication system according to claim 13 wherein the means for determining a preference for a first system resource over a second system resource further includes means for determining a magnitude of a preference of a first system resource over a second system resource.

15. The system for allocating a system resource of a wireless communication system according to claim 13 wherein the means for determining a preference for a first system resource over a second system resource further includes means for determining a preference of a channel having a first transmission frequency over a channel having a second transmission frequency.

16. The system for allocating a system resource of a wireless communication system according to claim 9 wherein the means for changing an allocation of the system resource to the one of the first and second subscribers having a lower resource sensitivity indicator to increase the efficiency of system resource allocation further includes means for changing an allocation of a channel frequency to the one of the first and second subscribers having a lower frequency resource sensitivity indicator to increase the efficiency of the allocation of channel frequencies.

17. A method for allocating a system resource to subscribers of a wireless communication system, the method comprising the steps of:

for each of a first subscriber unit and a second subscriber unit, determining a resource sensitivity indicator for a system resource allocated by the wireless communication system;

detecting an inefficient allocation of the system resource wherein an alternate allocation comes closer to fulfilling requests for allocation of a requested system resource than a present allocation;

selecting one of the first and second subscriber units in response to the resource sensitivity indicators of the first and second subscriber units, and in response to a potential increase in efficiency resulting in a change of system resource allocation; and

changing an allocation of the system resource to selected subscriber unit to increase the efficiency of system resource allocation.
