The present invention relates to a method of transmitting reverse signaling in CDMA trunking communication system, including: establishing PTT group call in CDMAtrunking communication system; transmitting broadcast channel allocation message by dispatch system, setting the long code masks of all the non-speaking user's reverse traffic channel to be the same; when the non-speaking user needs to transmit reverse signaling, turning on said reverse transmission power and transmitting said reverse signaling, and waiting for the confirmation message returned from base station in waiting time; when said confirmation message has been received, indicating a successful transmission and ending the transmission process; when said confirmation message hasn't been received, re-performing the step of transmitting reverse signaling. By setting the long code masks of the non-speaking user's reverse channel to be the same, the present invention effectively solves the problem that the reverse resource is limited in CDMA trunking communication system, thus effectively prevents the collision in transmitting the reverse signaling, and improves the reliability of transmitting the reverse signaling in CDMAtrunking communication system.
