Abstract

A base station-based communications system provides radio communication with battery-operated, portable radios, each radio including predetermined radio operating parameters corresponding to particular radio operating conditions. Each portable radio determines for itself one or more current radio operating condition(s), and based thereon, adjusts one or more radio operating parameters.

Claims

1. In a radio communications system wherein radio communications over radio frequency communications channels are coordinated from a base station having an associated geographical coverage area, a method for optimizing the performance of a portable or mobile battery-operated radio comprising the steps of:

establishing operating parameter values of the radio at various performance levels corresponding to particular radio operating conditions;

determining at the radio a current radio operating condition; and

adjusting the radio operating parameter value based on the determined radio operating condition,

wherein the operating parameter is a receiver settling time period during which a receiver in the radio changes to a different radio frequency communications channel such that as the current radio operating condition determined by the radio changes, the radio adjusts the receiver settling time period.

2. The method in claim 1, wherein the settling time period is reduced as the current radio operating condition improves, and the settling time period is increased as the current radio operating condition deteriorates.

3. The method in claim 1, wherein an operator manually sets the operating parameter of the radio to a desired performance level.

4. In a radio communications system wherein radio communications over radio frequency communications channels are coordinated from a base station having an associated geographical coverage area, a method for optimizing the performance of a portable or mobile battery-operated radio comprising the steps of:

establishing operating parameter values of the radio at various performance levels corresponding to particular radio operating conditions;

determining at the radio a current radio operating condition; and

adjusting the radio operating parameter value based on the determined radio operating condition,

wherein the operating parameter is a transmit to receive settling time period during which a transceiver in the radio changes transmitting on one radio frequency communications channel to receiving on a different radio frequency communications channel such that as the current radio operating condition determined by the radio changes, the radio adjusts the settling time period.

5. The method in claim 4, wherein the settling time period is reduced as the current radio operating condition improves, and the settling time period is increased as the current radio operating condition deteriorates.

6. The method in claim 4, wherein an operator manually sets the operating parameter of the radio to a desired performance level.

7. In a radio communications system wherein radio communications over radio frequency communications channels are coordinated from a base station having an associated geographical coverage area, a method for optimizing the performance of a portable or mobile battery-operated radio comprising the steps of:

establishing operating parameter values of the radio at various performance levels corresponding to particular radio operating conditions;

determining at the radio a current radio operating condition; and

adjusting the radio operating parameter value based on the determined radio operating condition,

wherein the operating parameter is a receive to transmit settling time period during which a transceiver in the radio changes receiving on one radio frequency communications channel to transmitting on a different radio frequency communications channel such that as the current radio operating condition determined by the radio changes, the radio adjusts the settling time period.

8. The method in claim 7, wherein the settling time period is reduced as the current radio operating condition improves, and the settling time period is increased as the current radio operating condition deteriorates.

9. The method in claim 7, wherein an operator manually sets the operating parameter of the radio to a desired performance level.

10. A radio communications system, comprising:

plural battery-operated, portable or mobile radios, each radio including predetermined radio operating parameter values corresponding to particular radio operating conditions;

a base station with plural radio transceivers each assigned a pair of radio communications frequencies for coordinating radio communications with at least one of the plural radios located in a geographical coverage area associated with the base station; and

wherein the operating parameter is a receiver settling time period during which a receiver in the radio changes to a different radio frequency communications channel such that as the current radio operating condition determined by the radio changes, the electronic circuitry adjusts the receiver settling time period.

11. The system in claim 10, wherein the electronic circuitry reduces the settling time period as the current radio operating condition improves, and increases the settling time period as the current radio operation condition deteriorates.

12. The system in claim 10, wherein an operator manually sets the operating parameter of the radio to a desired performance level.

13. A radio communications system, comprising:

plural battery-operated, portable or mobile radios, each radio including predetermined radio operating parameter values corresponding to particular radio operating conditions;

a base station with plural radio transceivers each assigned a pair of radio communications frequencies for coordinating radio communications with at least one of the plural radios located in a geographical coverage area associated with the base station; and

electronic circuitry determining a current radio operating condition and adjusting the radio operating parameter value based on the current radio operating condition,

wherein the operating parameters is a transmit to receiver settling time period during which a transceiver in the radio changes transmitting on one radio frequency communications channel to receiving on a different radio frequency communications channel such that as the current radio operating condition determined by the radio changes, the electronic circuitry adjusts the settling time period.

14. The system in claim 13, wherein the electronic circuitry reduces the settling time period as the current radio operating condition improves, and increases the settling time period as the current radio operating condition deteriorates.

15. The method in claim 13, wherein an operator manually sets the operating parameter of the radio to a desired performance level.

16. A radio communications system, comprising:

plural battery-operated, portable or mobile radios, each radio including predetermined radio operating parameter values corresponding to particular radio operating conditions;
