Trunking system access method
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 among the plurality of communication units, wherein one of the communication resources functions as a control channel and the remaining communication resources function as voice channels, wherein, from time to time, the control channel is used as a voice channel, and, when the control channel is used as a voice channel, the plurality of communication units monitor one of the voice channels as a monitored voice channel, a method for the communication system to process control information in an efficient manner, the method comprises the steps of:
- a) when a communication unit has control information to transmit to the communication resource allocator, determining whether the monitored voice channel is busy;
b) when the monitored voice channel is not busy, transmitting, by the communication unit, the control information on the monitored voice channel;
c) transmitting, by the communication resource allocator, recommended channel parameters on at least the monitored voice channel, wherein the recommended channel parameters comprise at least one recommended channel;
d) when the monitored voice channel is busy, decoding, by the communication unit, the recommended channel parameters to ascertain said at least one recommended channel;
e) determining, by the communication unit, whether said at least one recommended channel is usable; and
f) when the recommended channel is usable, transmitting, by the communication unit, the control information on said at least one recommended channel.

Abstract
In a communication system, the following describes a method for the communication system to more efficiently process control information when the control channel is temporarily used as a voice channel. When a communication unit has control information to transmit to the communication resource allocator, it determines whether the monitored voice channel is busy. When the monitored voice channel is not busy, the communication unit transmits the control information to the communication resource allocator on the monitored voice channel. Regardless of whether the monitored voice channel is busy or not, the communication resource allocator transmits recommended channel parameters on the monitored channel wherein the recommended channel parameters comprises at least one recommended channel. When the monitored voice channel is busy, the communication unit decodes the recommended channel parameters to ascertain the at least one recommended channel. Having done this, the communication unit determines whether the at least one recommended channel is usable, and when the recommended channel is usable, the communication unit transmits its control information on that channel to the communication resource allocator.

8. 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 among the plurality of communication units, wherein one of the communication resources functions as a control channel and the remaining communication resources function as voice channels, wherein, from time to time, the control channel is used as a voice channel, and, when the control channel is used as a voice channel, the plurality of communication units monitor one of the voice channels as a monitored voice channel, a method for a communication unit to have its control information processed in an efficient manner, the method comprises the steps of:
-
a) when the communication unit has control information to transmit to the communication resource allocator, determining whether the monitored voice channel is busy; b) when the monitored voice channel is not busy, transmitting the control information on the monitored voice channel; c) receiving recommended channel parameters on at least the monitored voice channel, wherein the recommended channel parameters comprise at least one recommended channel; d) when the monitored voice channel is busy, decoding the recommended channel parameters to ascertain said at least one recommended channel; e) determining whether said at least one recommended channel is usable; and f) when the recommended channel is usable, transmitting the control information on said at least one recommended channel. - View Dependent Claims (9, 10, 11, 12, 13, 14)
