摘要： The present invention relates to a private network communication technology, and it provides an implementation method, terminal, relay station and system for DMR private communication with respect to the existing defects that each of the communication terminals can only communicate with each other by using the same time slot in a group, and thereby a frequency width of 12.5 KHz can not be used sufficiently. The 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. Each path of DMR private network communication only occupies one time slot, the case of occupying different time slots at different time can be avoided. 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 12.5 KHz.

摘要： The present invention relates to private network communication techniques, and provides a DMR private network communication terminal, communication system, and an implementation method thereof with respect to the drawback existing in the prior art that the idle time slot can not be determined in advance, and therefore the idle time slot can not be utilized to initiate new private network communication. The DMR private network communication terminal includes: a communication module, adapted to receive/transmit DMR private network communication; a synchronization module, adapted to listen to a DMR synchronization pattern and establish synchronization with the DMR synchronization pattern, determine the time slot occupied by the DMR synchronization pattern, and thereby lock the pre-assigned communication time slot, and controls the communication module to receive/transmit DMR private network communication in the pre-assigned time slot. The present invention further provides a DMR private network communication system and an implementation method thereof. By restricting private network communication terminals to perform communication only in the preset communication time slot, the same channel of private network communication is assured to be transmitted in the same time slot. Thus, other terminals can lock the idle time slot in advance and initiate new private network communication, and therefore the DMR frequency spectrum resource can be fully utilized.
