Abstract

In a trunked communication system using intelligent repeaters (101), each intelligent repeater performs a series of tests (602, 606, 610, 614, and 618) on its own functionality. The results of these tests are transmitted (622) to a resource manager, which is one of the intelligent repeaters at a communications site. Using the results of these tests, the resource manager then selects one or more of the intelligent repeaters to perform the functions of authorization, resource allocation (708), and logging of communications (713).

Claims

1. A method of managing resources by a plurality of intelligent repeaters at a trunked communication site, comprising the steps of;

receiving, by a resource manager of said trunked communication site, status information from the plurality of intelligent repeaters;

analyzing said status information;

selecting a first of the plurality of intelligent repeaters to perform authorization of access functions, which authorization includes comparing stored IDs that correspond to authorized communication units with IDs of requesting communication units;

selecting a second of the plurality of intelligent repeaters, which second intelligent repeater is different than the first intelligent repeater, to perform resource allocation functions, which functions include determining communication resources that are to be used to service a requested communication;

selecting a third of the plurality of intelligent repeaters, which third intelligent repeater is different than both the first and second intelligent repeater, to perform logging functions;

informing the plurality of intelligent repeaters of said first, said second, and said third of the plurality of intelligent repeaters; and

informing said second of the plurality of intelligent repeaters of said status information.

2. The method of claim 1, further comprising the steps of:

receiving subsequent status information from the plurality of intelligent repeaters;

analyzing said subsequent status information for a failure of any of said first, said second, and said third of the plurality of intelligent repeaters; and

when said failure is found;

selecting a fourth of the plurality of intelligent repeaters to perform authorization of access functions;

selecting a fifth of the plurality of intelligent repeaters to perform resource allocation functions;

selecting a sixth of the plurality of intelligent repeaters to perform logging functions;

informing the plurality of intelligent repeaters of said fourth, said fifth, and said sixth of the plurality of intelligent repeaters; and

informing said fifth of the plurality of intelligent repeaters of said status information.

3. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of at least one element of each intelligent repeater to produce test results; and

transmitting said test results to said resource manager.

4. The method of claim 3, wherein said at least one element is comprised of one of a signal processor, a control information processor, and a storing means.

5. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of a transceiver for each of said plurality of intelligent repeaters to produce test results; and

transmitting said test results to said resource manager.

6. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of a public communication network interface of each intelligent repeater to produce test results; and

transmitting said test results to said resource manager.

7. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of a private off-site communication network interface of each intelligent repeater to produce test results; and

transmitting said test results to said resource manager.

8. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of a private on-site communication network interface of each intelligent repeater to produce test results; and

transmitting said test results to said resource manager.

9. The method of claim 1, wherein said status information is determined by a method comprising the steps of:

testing functionality of at least one element of each intelligent repeater to produce a first test result; and

testing functionality of a transceiver for each of said plurality of intelligent repeaters to produce a second test result; and

testing functionality of a public communication network interface of each intelligent repeater to produce a third test result; and

testing functionality of a private off-site communication network interface of each intelligent repeater to produce a fourth test result;

testing functionality of a private on-site communication network interface of each intelligent repeater to produce a fifth test result; and

transmitting all of said test results to said resource manager.

10. The method of claim 9, wherein said at least one element is comprised of one of a signal processor, a control information processor, and a storing means.

11. A communication system that managing resources by a plurality of intelligent repeaters at a trunked communication site, the system comprising:

means for receiving, by a resource manager of said trunked communication site, status information from the plurality of intelligent repeaters;

means, responsive to said receiving means, for analyzing said status information;

means, responsive to said analyzing means, for selecting a first of the plurality of intelligent repeaters to perform authorization of access functions, which authorization includes comparing stored IDs that correspond to authorized communication units with IDs Of requesting communication units;

means, responsive to said analyzing means, for selecting a second of the plurality of intelligent repeaters, which second intelligent repeater is different than the first intelligent repeater, to perform resource allocation functions, which functions include determining communication resources that are to be used to service a requested communication;

means, responsive to said analyzing means, for selecting a third of the plurality of intelligent repeaters, which third intelligent repeater is different than both the first and second intelligent repeater, to perform logging functions;

means, responsive to each of said selecting means, for informing the plurality of intelligent repeaters of said first, said second, and said third of the plurality of intelligent repeaters; and

means, responsive to each of said selecting means, for informing said second of the plurality of intelligent repeaters of said status information.

12. The communication system of claim 11, further comprising:

means for receiving subsequent status information from the plurality of intelligent repeaters;

means, responsive to said means for receiving subsequent status information, for analyzing said subsequent status information for a failure of any of said first, said second, and said third of the plurality of intelligent repeaters; and

means, responsive to said failure, for selecting a fourth of the plurality of intelligent repeaters to perform authorization of access functions;

means, responsive to said failure, for selecting a fifth of the plurality of intelligent repeaters to perform resource allocation functions;

means, responsive to said failure, for selecting a sixth of the plurality of intelligent repeaters to perform logging functions;

means, responsive to each of said selecting means, for informing the plurality of intelligent repeaters of said fourth, said fifth, and said sixth of the plurality of intelligent repeaters; and

means, responsive to each of said selecting means, for informing said fifth of the plurality of intelligent repeaters of said status information.
