Abstract:
The present invention provides an implementation method, terminal, relay station and system for DMR private communication. A DMR private network communication terminal includes a communication module for receiving CACH information, receiving and transmitting DMR private network communication, a synchronization module for establishing synchronization and determining which time slot the received DMR private network communication occupies based on the received CACH information; and controlling the communication module to make a response for the received DMR private network communication in the time slot. The present invention further provides an implementation method, relay station and system for DMR private network communication. In this case, the stability of the idle time slot can be ensured, and other DMR private network communication terminals can initiate new DMR private network communication by locking unoccupied idle time slot; thereby achieving a full usage of the frequency width of 12.5KHz.
