Abstract

An intelligent repeater (101) is used to control trunked communications at a trunked communication site in a trunked communications system. The intelligent repeator (101) transceives and signal processes radio frequency signals. The intelligent repeater (101) also processes and stores control information. The control information and processed signals are interfaced (109, 110, and 111) directly to an external communication network (117, 118, and 119), without use of a separate central controller for the trunked communication site or system.

Claims

1. A method of establishing trunked communications at a trunked communication site using a plurality of intelligent repeaters, comprising the steps of:

A) receiving a communication resource request;

B) sourcing from a first intelligent repeater some, but not all, call establishment information necessary to support the communication resource request;

C) sourcing from a second intelligent repeater additional call establishment information that is necessary to support the communication resource request, wherein the additional call establishment information is at least partially different than the call establishment information that is sourced by the first intelligent repeater;

D) using the call establishment information as sourced by at least the first and second intelligent repeaters to assign a communication resource in response to the communication resource request.

2. The method of claim 1, wherein the first and second intelligent repeaters establish a call with at least one of either a public communication network and a private communication network.

3. The method of claim 1, wherein the sourcing step further comprises the step of comparing an identity of a communication unit that sourced the communication resource request to a predetermined list of authorized identities.

4. The method of claim 1, further comprising the step of transferring processed signals between the first intelligent repeater and the second intelligent repeater.

5. A method of establishing trunked communications at a trunked communication site whereat a plurality of intelligent repeaters reside, comprising the steps of:

receiving, by a first intelligent repeater, a communication resource request from a communication unit;

decoding, by said first intelligent repeater, said communication resource request;

deciding by said first intelligent repeater which of the plurality of intelligent repeaters will authorize access for said communication resource request, thereby choosing a second intelligent repeater;

authorizing, by said second intelligent repeater, access to a communication resource for the communication unit;

establishing by said first intelligent repeater which of the plurality of intelligent repeaters will determine required communication resources to fulfill said communication resource request, thereby choosing a third intelligent repeater;

determining, by said third intelligent repeater, required communication resources to fulfill said communication resource request;

wherein said first intelligent repeater, said second intelligent repeater, and said third intelligent repeater are either the same intelligent repeater, two of the plurality of intelligent repeaters, or three of the plurality of intelligent repeaters.

6. The method of claim 5, wherein said required communication resources comprise at least one of either a public communication network or a private communication network.

7. The method of claim 5, wherein said authorizing step further comprises the step of comparing an identity of a communication unit that sourced said communication resource request to a predetermined list of authorized identities.

8. The method of claim 5, further comprising the step of transferring processed signals between said first intelligent repeater, said second intelligent repeater, and said third intelligent repeater.

9. A method of establishing trunked communications at a trunked communication site using a plurality of intelligent repeaters, comprising the steps of:

A) receiving a request for at least one communication resource from a communication unit;

B) sourcing from a first intelligent repeater some, but not all, call establishment information necessary to support the communication resource request;

C) selecting a second intelligent repeater that is not the first intelligent repeater;

D) sourcing from the second intelligent repeater additional call establishment information that is necessary to support the communication resource request, wherein the additional call establishment information is at least partially different than the call establishment information that is sourced by the first intelligent repeater;

E) using the call establishment information as sourced by at least the first and second intelligent repeaters to assign a communication resource in response to the communication resource request.

10. The system of claim 9, wherein the additional call establishment information comprises information regarding which of the plurality of intelligent repeaters is assigned to provide the at least one communication resource.

11. The system of claim 9, wherein the additional call establishment information comprises information for logging said communication unit'"'"'s use of said at least one communication resource.
