Method for processing communication requests
First Claim
1. In a trunking communication system that comprises a plurality of communication units, a limited number of communication resources that are transceived via a predetermined number of repeaters, and a communication resource allocator that allocates the limited number of communication resources to a talk group of communication units for a particular communication, wherein a first communication unit of the talk group transmits a request to communicate to the communication resource allocator while a second communication unit of the talk group is communicating with the talk group on an allocated communication resource, a method for the communication resource allocator to process the request to communicate from the first communication unit, the method comprising the steps of:
- by the communicationa) while the second communication unit is communicating with the talk group on the allocated communication resource, receiving a request to communicate from the first communication unit to produce a new request to communicate;
b) storing the new request to communicate to produce a stored communication request;
c) transmitting a response to the request to communicate to the first communication unit, wherein the first communication unit, upon receiving the response, resumes receiving the remainder of the communication from the second communication unit; and
d) after the second communication has stopped communicating with the talk group, retrieving the stored communication request based upon a predetermined retrieval pattern, and then transmitting a permission signal to the first communication unit.

Abstract
A communication unit that is registered in a trunked communication system can continue to receive a communication from a first communication unit after initiating a push-to-talk request while the first communication unit is transmitting voice data in the following manner. Having allocated a communication resource to a group of communication units and while processing a request to communicate for the first communication unit, a communication resource allocator receives a request to communicate from a second communication unit to produce a new request to communicate. The communication resource allocator stores the new request to communicate and transmits a response to the second communication unit such that the second communication unit can continue to receive the remainder of the communication from the first communication unit. Once the first communication unit has stopped transmitting its communication, the communication resource allocator retrieves the stored communication request based upon a predetermined retrieval pattern.

5. In a trunking communication system that comprises a plurality of communication units, a limited number of communication resources that are transceived via a predetermined number of repeaters, and a communication resource allocator that allocates the limited number of communication resources to a talk group of communication units for a particular communication, wherein a first communication unit of the talk group transmits a request to communicate to the communication resource allocator while a second communication unit of the talk group is communicating with the talk group on an allocated communication resource, a method for processing the request to communicate from the first communication unit, the method comprising the steps of:
-
by the first communication unit; a) while the second communication unit is communicating with the talk group on the allocated communication resource, transmitting a request to communicate to the communication resource allocator; b) from the communication resource allocator, receiving a response to the request to communicate to produce a received response; c) storing the received response; and d) after storing the received response, resuming to receive the remainder of the communication from the second communication unit.

6. The method of claim 9 further comprises a step of transmitting, by the first communication unit, a revoke request message to the communication resource allocator that indicates that the first communication unit no longer requests to communicate on the allocated communication resource.
