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 priorart that the idle time slot can not be determined in advance, and therefore the idle timeslot can not be utilized to initiate new private network communication. The DMR privatenetwork communication terminal includes: a communication module, adapted toreceive/transmit DMR private network communication; a synchronization module,adapted to listen to a DMR synchronization pattern and establish synchronization withthe DMR synchronization pattern, determine the time slot occupied by the DMR
synchronization pattern, and thereby lock the pre-assigned communication time slot, andcontrols the communication module to receive/transmit DMR private networkcommunication in the pre-assigned time slot. The present invention further provides aDMR private network communication system and an implementation method thereof. Byrestricting private network communication terminals to perform communication only in
the preset communication time slot, the same channel of private network communicationis assured to be transmitted in the same time slot. Thus, other terminals can lock the idletime slot in advance and initiate new private network communication, and therefore theDMR frequency spectrum resource can be fully utilized.
