Patent ID: 8441990

Claim:
A method for sharing reverse channels in a trunk communication system, comprising the steps of: step A, establishing a forward channel and multiple sharing reverse channels in a group; step B, a mobile station in idle state determining a sharing reverse channel which could be used by the mobile station according to information of the multiple sharing reverse channels; and step C, the mobile station transmitting information through the determined sharing reverse channel; wherein the method further comprises the following steps: step F, adding priority identifiers each corresponding to every sharing reverse channel in the information of the multiple sharing reverse channels; and step G, after receiving the information of the multiple sharing reverse channels, the mobile station in idle state comparing the priority thereof with the priorities of the multiple sharing reverse channels, and if a priority of a sharing reverse channel is higher than the priority of the mobile station, the mobile station being not able to send the reverse signaling by using the sharing reverse channel; or otherwise, the mobile station determining M sharing reverse channels with the priority of the mobile station being higher than or equal to the priorities of the M sharing reverse channels, and determining a sharing reverse channel from the M sharing reverse channels for the mobile station by way of the randomization calculating to send the reverse signaling.
