Abstract

An intelligent repeater interface (101) connected to a non-intelligent repeater (102) is used to control trunked communications at a trunked communication site in a trunked communications system. The intelligent repeater interface (101) signal processes radio frequency signals received by or transmitted from a non-intelligent repeater. The intelligent repeater interface (101) also processes and stores control information. The control information and processed signals are interfaced (108, 109, and 110) directly to an external communication network (111, 112, and 113), without use of a separate central controller for the trunked communication site or system and without replacing the non-intelligent repeater with an intelligent repeater.

Claims

1. An intelligent repeater interface comprising:

signal processing means for processing signals from a non-intelligent repeater;

processing means, operatively coupled to said signal processing means, for processing control information;

means, coupled to said processing means for processing control information, for storing said control information; and

interfacing means, operatively coupled to said signal processing means, said processing means, and said non-intelligent repeater, for interfacing said stored control information and said processed signals directly to at least one external communication network; and

means, operatively coupled to said interfacing means, for distributing call processing functions amongst a plurality of intelligent repeater interfaces and/or intelligent repeaters.

2. The interface for a non-intelligent repeater of claim 1, wherein said external communication network is comprised of a public communication network.

3. The interface for a non-intelligent repeater of claim 1, wherein said external communication network is comprised of a private off-site communication network.

4. The interface for a non-intelligent repeater of claim 1, wherein said external communication network is comprised of a private on-site communication network.

5. The interface for a non-intelligent repeater of claim 1, wherein two or more non-intelligent repeaters are attached to the interfacing means.

6. A method of establishing trunked communications at a trunked communication site comprising the steps off

receiving a communication resource request;

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

sourcing from either a second intelligent repeater interface or a first 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 interface;

using the call establishment information as sourced by at least the first intelligent repeater interface and either the second intelligent repeater interface or the first intelligent repeater to assign a communication resource in response to the communication resource request.

7. The method of claim 6, wherein the first intelligent repeater interface and either the second intelligent repeater interface or the first intelligent repeater establish a call with one of either a public communication network or a private communication network.

8. The method of claim 6, further comprising the step of transferring processed signals between the first intelligent repeater interface and either the second intelligent repeater interface or the first intelligent repeater.

9. A method of establishing trunked communications at a trunked communication site whereat resides a plurality of intelligent repeater interfaces connected to a plurality of non-intelligent repeaters, comprising the steps of:

receiving a communication resource request;

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

selecting a second intelligent repeater interface that is not the first intelligent repeater interface;

sourcing from the second intelligent repeater interface 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 interface;

using the call establishment information as sourced by at least the first and second intelligent repeater interfaces to assign a communication resource sourced by one of the plurality of non-intelligent repeaters in response to the communication resource request.

10. The method of claim 9, wherein the first intelligent repeater interface and the second intelligent repeater interface establish a call with one of either a public communication network or a private communication network.

11. The method of claim 9, further comprising the step of transferring processed signals between the first intelligent repeater interface and the second intelligent repeater interface.

12. The method of claim 9, wherein a local area network forms a communication link shared by the plurality of intelligent repeater interfaces through private on-site interfaces.

13. An intelligent repeater interface for a non-intelligent repeater, the intelligent repeater interface comprising:

an interface operably coupled to the non-intelligent repeater; and

a call processor operably coupled to the interface, and having at least three selectable modes of operation, wherein;

i) in a first mode of operation, the call processor receives all call establishment information necessary to support a requested radio communication;

ii) in a second mode of operation, the call processor sources some, but not all, of the call establishment information necessary to support a requested radio communication;

iii) in a third mode of operation, the call processor sources all of the call establishment information necessary to support a requested radio communication;

and wherein none of the call establishment information is sourced by the non-intelligent repeater in the first mode of operation, the second mode of operation, or the third mode of operation, and at least some of the call establishment information is received by the non-intelligent repeater in the first mode of operation, the second mode of operation, or the third mode of operation when the non-intelligent repeater is used in the requested radio communication.

14. The intelligent repeater interface of claim 13, wherein at least one intelligent repeater is operatively coupled to the intelligent repeater interface.

15. The intelligent repeater interface of claim 13, further comprising means for interfacing directly to at least one external communication network.

16. A method of distributing functions in a communication system including a plurality of non-intelligent repeaters connected to a plurality of intelligent repeater interfaces, comprising the steps of:

processing signal information;

transferring said processed signal information over an interface between a first intelligent repeater interface and a second intelligent repeater interface; and

allocating resources amongst the plurality of intelligent repeater interfaces based at least in part on said processed signal information.

17. The method of claim 16, wherein the communication system also includes at least one intelligent repeater and wherein resources are allocated amongst the plurality of intelligent repeater interfaces and the at least one intelligent repeater.
