摘要： 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.

摘要翻译：本发明涉及一种在CDMA发送反向信令集群通信系统中，的方法，包括：建立在CDMAtrunking通信系统PTT群呼叫; 由调度系统中发送广播信道分配消息，将所有不说话的用户的反向业务信道的长码掩码向是相同的; 当非讲话的用户需要发送反向信令，接通所述反向发射功率和发送所述反向信令，并等待确认消息在等待时间从基站返回; 当已经接收到所述确认消息，指示成功传输和结束传输过程; 当还没有接收到所述确认消息，重新进行反向传输信令的步骤。通过设置非讲话的用户的反向信道的长码掩码向是相同的，本发明有效地解决了这个问题，并在反向资源被限制在CDMA集群通信系统中，从而有效地防止了在发送反向信令碰撞，并改善发射在CDMAtrunking通信系统反向信令的可靠性。
