Description
Technical Field
[0001] The present invention relates to the technical field of intercom communication, and in particular to a method and system for sending same-frequency reverse signaling based on a cluster mode. Background Art
[0002] In the PDT or DMR cluster system, in order to interrupt the terminal user who is transmitting, it is necessary to transmit reverse signaling in the adjacent time slot of the terminal user's working time slot. However, in the cluster system, the terminal's transmission and reception are at different frequencies. Therefore, after the terminal transmits its own data on the transmission frequency, it is required to immediately switch back to the receiving frequency for data reception. Conversely, after the reception is completed, it is also necessary to immediately return to the transmission frequency to send the next frame of data. This requires the RF circuit to complete the transmission and reception switching process in a very short time. This not only places high demands on the hardware design on the terminal side, but also correspondingly leads to an increase in the hardware cost on the terminal side; How to send same-frequency reverse signaling in cluster mode without switching the receiving and transmitting frequencies is a problem we need to solve. To this end, a method and system for sending same-frequency reverse signaling based on cluster mode are provided. Summary of the invention
