Abstract

A method for optimizing allocation of telephone and communication resources in a trunked communication system (100) is accomplished in the following manner. Upon receiving a resource request, a communication resource allocator, determines whether the request is for a communication resource (trunking call) or for a telephone resource (telephone call). When the request is for a communication resource, the communication resource allocator, allocates a communication resource from a broadcast unit in a second set of broadcast units. If no communication resources are available in the second set of broadcast units, the communication resource allocator allocates a communication resource from a broadcast unit of a first set of broadcast units in a predetermined order, wherein the broadcast units in the first set are affiliated with a telephone resource and a communication resource.

Claims

1. In a trunking communication system that includes a plurality of communication units, a telephone resource allocator, a plurality of telephone resources, a limited number of communication resources, a plurality of broadcast units, and a communication resource allocator, wherein the plurality of broadcast units includes a predetermined first set of broadcast units and a predetermined second set of broadcast units, and wherein each broadcast unit in the predetermined first set of broadcast units is operably coupled to a telephone resource of the plurality of telephone resources, a method for allocating the telephone resources and the communication resources, the method comprises the steps of:

a) receiving, by the communication resource allocator, a resource request from a requesting source;

b) determining, by the communication resource allocator, whether the resource request contains a request for a telephone resource or a communication resource;

c) when the resource request contains a request for a communication resource, allocating, by the communication resource allocator, a communication resource of a broadcast unit of the predetermined second set of broadcast units to the requesting source when the broadcast unit of the predetermined second set of broadcast units has an available communication resource; and

d) when the broadcast unit of the predetermined second set of broadcast units does not have an available communication resource, allocating, by the communication resource allocator, a communication resource of a broadcast unit of the predetermined first set of broadcast units in a first predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available communication resource and is not supporting a telephone communication.

2. The method of claim 1 further comprises the step of:

e) when the requesting source is a communication unit and the resource request contains a telephone resource request, allocating, by the communication resource allocator, a telephone resource of a broadcast unit of the predetermined first set of broadcast units in the first predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available telephone resource.

3. The method of claim 1 further comprises the step of:

e) when the requesting source is a landline telephone user and the resource request contains a telephone resource request, allocating, by the telephone resource allocator, a telephone resource of the predetermined first set of broadcast units in a second predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available telephone resource.

4. In the method of claim 2, the allocation of the telephone resource in a second predetermined order, and the allocation of a communication resource in the first predetermined order, wherein the first predetermined order derives from the second predetermined order, further comprises, arranging the first predetermined order and the second predetermined order to minimize contention of the broadcast unit in the predetermined first set of broadcast units between a communication unit telephone request and a landline user request.

5. In the method of claim 1, step (d) further comprises, providing, by the broadcast unit of the predetermined first set of broadcast units, a telephone busy signal to the operably coupled telephone resource when the broadcast unit is supporting a trunking communication via the communication that was allocated.

6. In the method of claim 3, the allocation of the telephone resource in the second predetermined order further comprises arranging the second predetermined order in a sequential pattern such that if a telephone resource is supporting a communication or is not answering after a programmed number of rings, the telephone resource signals by ringing the next telephone resource programmed in the sequential pattern, wherein the sequential pattern is repeated until the telephone resource becomes available.

7. In a trunking communication system that includes a plurality of communication units, a telephone resource allocator, a plurality of telephone resources, a limited number of communication resources, a plurality of broadcast units, and a communication resource allocator, wherein the plurality of broadcast units transceive the limited number of communication resources, wherein the plurality of broadcast units includes a predetermined first set of broadcast units and a predetermined second set of broadcast units, and wherein each broadcast unit in the predetermined first set of broadcast units is operably coupled to a telephone resource of the plurality of telephone resources, a method for allocating the telephone resources and the communication resources, the method comprises the steps of:

a) receiving, by the communication resource allocator, a resource request, wherein the resource request include a request for a communication resource;

b) allocating, by the communication resource allocator, a communication resource of a broadcast unit of the predetermined second set of broadcast units to the requesting source when the broadcast unit of the predetermined second set of broadcast units has an available communication resource; and

c) when the broadcast unit of the predetermined second set of broadcast units does not have an available communication resource, allocating, by the communication resource allocator, a communication resource of a broadcast unit of the predetermined first set of broadcast units in a first predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available communication resource and is not supporting a telephone communication.

8. The method of claim 7 further comprises the step of:

d) when the resource request is from a communication unit and includes a telephone resource request, allocating, by the communication resource allocator, a telephone resource of a broadcast unit of the predetermined first set of broadcast units in the first predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available telephone resource.

9. The method of claim 7 further comprises the step of:

d) when the resource request is from a landline telephone user and contains a telephone resource request, allocating, by the telephone resource allocator, a telephone resource of the predetermined first set of broadcast units in a second predetermined order when the broadcast unit of the predetermined first set of broadcast units has an available telephone resource.

10. In the method of claim 8, the allocation of the telephone resource in a second predetermined order, and the allocation of a communication resource in the first predetermined order, wherein the first predetermined order derives from the second predetermined order, further comprises, arranging the first predetermined order and the second predetermined order to minimize contention of the broadcast unit in the predetermined first set of broadcast units between a communication unit telephone request and a landline user request.

11. In the method of claim 7, step (c) further comprises, providing, by the broadcast unit of the predetermined first set of broadcast units, a telephone busy signal to the operably coupled telephone resource when the broadcast unit is supporting a trunking communication via the communication that was allocated.

12. In the method of claim 9, the allocation of the telephone resource in the second predetermined order further comprises arranging the second predetermined order in a sequential pattern such that if a telephone resource is supporting a communication or is not answering after a programmed number of rings, the telephone resource signals by ringing the next telephone resource programmed in the sequential pattern, wherein the sequential pattern is repeated until the telephone resource becomes available.
