Method to reduce push-to-talk call setup time
First Claim
1. A method to reduce call setup time of a dispatch communication comprising:
- receiving a message from an originating dispatch device intended for a target dispatch device;
inspecting, by a base station servicing the target dispatch device, the message for a call request announcement;
determining if a radio resource is available for the target dispatch device;
transmitting from the base station servicing the target dispatch device a call request acknowledgement message to the originating dispatch device after the base station servicing the target dispatch device holds for a period of time based on a traffic channel setup time for the target dispatch device and a time required to transmit the call request acknowledgement message; and
sending the call request announcement to the target dispatch device as a parallel process with said transmitting the call request acknowledgement message.

Abstract
System and method for reducing call setup time of a dispatch communication. In one embodiment, a method includes receiving a message from an originating dispatch device intended for a target dispatch device. The message may be inspected by a base transceiver station for a call request announcement. The method may further include determining if a radio resource is available for the target dispatch device. According to an additional embodiment of the invention, a call request acknowledgement message may be transmitted to the originating dispatch device after a period of time to ensure a guaranteed talk permit. The call request announcement may also be transmitted to the target dispatch device after the period of time.

7. A dispatch communication system with improved call setup time comprising:
-
a first dispatch device configured to communicate with a dispatch communication network; and a base station transceiver network interface configured to connect the dispatch communication network to a target dispatch device, wherein said network interface is configured to; receive a message from the first dispatch device intended for the target dispatch device; inspect the message for a call request announcement; determine if a radio resource is available for the target dispatch device; transmit a call request acknowledgement message to the first dispatch device after holding for a period of time based on a traffic channel setup time for the target dispatch device and a time required to transmit the call request acknowledgement message; and send the call request announcement to the target dispatch device as a parallel process with said transmitting the call request acknowledgement message. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A computer program product stored in a non-transitory processor readable medium comprising:
-
a computer usable medium having computer executable program code embodied therein to setup a dispatch communication, the computer program product having; computer readable program code to receive a message from an originating dispatch device intended for a target dispatch device; computer readable program code to inspect, by a base station servicing the target dispatch device, the message for a call request announcement; computer readable program code to determine if a radio resource is available for the target dispatch device;
computer readable program code to transmit from the base station servicing the target dispatch device a call request acknowledgement message to the originating dispatch device after the base station servicing the target dispatch device holds for a period of time based on a traffic channel setup time for the target dispatch device and a time required to transmit the call request acknowledgement message; andcomputer readable program code to allocate the radio resource for the target dispatch device, wherein said transmitting and said allocating are performed in parallel. - View Dependent Claims (15, 16, 17)
