Communication system that provides adjustable communication service availability to subscribers

1. A communication system that provides communication services to a plurality of communication devices over one or more radio frequency (RF) channels, comprising:

an operator interface configured to interactively specify a minimum probability of communication service availability to the plurality of the communication devices, the minimum probability being in the form of a percent availability figure; and

a resource controller configured to receive the minimum probability from the operator interface, change a bit rate used to communicate data with at least one of the plurality of communication devices based on the minimum probability, and adjust the communication service availability to the plurality of communication devices according to the changed bit rate while continuing to provide the communication services to all of the plurality of communication devices.

2. The communication system of claim 1 , wherein

the bit rate used to communicate data with the at least one of the plurality of communication devices is changed by modifying a coding algorithm used to communicate information with the at least one of the plurality of communication devices.

3. The communication system of claim 1 , wherein the resource controller monitors one or more system parameters to interactively modify communication service availability to the plurality of the communication devices.

4. The communication system of claim 3 , wherein a system parameter essentially consists of at least one of a number of registered subscribers, load on a RF channel, load on a communication resource, a traffic mix, or a coding algorithm.

5. The communication system of claim 3 , wherein the resource controller monitors load on one or more communication resources over a defined period of time to determine how to control the at least one communication resource.

6. The communication system of claim 3 , wherein the resource controller monitoring the time that communication resource is out of service for deriving load distributions, to control the at least one communication resource.

7. The communication system of claim 1 , wherein the operator interface is capable of adjusting a system parameter corresponding to a maximum number of registered subscribers to modifying the minimum probability of communication service availability to the plurality of communication devices.

8. The communication system of claim 1 , wherein the minimum probability of communication service availability is specified as a number of nines.

9. A method for providing communication service to a plurality of communication devices over one or more radio frequency (RF) channels, comprising:

monitoring at least one system parameter to interactively modify communication service availability to the plurality communication devices;

specifying a minimum probability of communication service availability to the plurality of communication devices, the minimum probability being in the form of a percent availability figure;

changing a bit rate used to communicate with at least one of the plurality of communication devices based on the specified minimum probability; and

adjusting availability to the plurality of communication devices according to the changed bit rate while continuing to provide the communication services to all of the plurality of communication devices.

10. The method of claim 9 , wherein

the bit rate used to communicate data with the at least one of the plurality of communication devices is changed by modifying a coding algorithm used to provide voice services to the at least one of the plurality of communication devices.

11. The method of claim 9 , wherein the at least one system parameter includes at least one of a number of registered subscribers, load on a RF channel, load on a communication resource, a traffic mix, or a coding algorithm.

12. The method of claim 11 , wherein the load on one or more communication resources is monitored over a defined period of time.

13. The method of claim 12 , wherein load distributions for each communication resource is derived based on a monitored load on a corresponding communication resource.

14. The method of claim 13 , wherein time that a communication resource is out of service is monitored for deriving loud distributions.

15. The method of claim 9 , further comprising adjusting a system parameter corresponding to a maximum number of registered subscribers to modify the minimum probability of communication service availability to the plurality of communication devices.

16. The method of claim 9 , wherein the minimum probability of communication service availability is specified as a number of nines.
