Digital mobile radio private network communication terminal and system, and method of implementation for digital mobile radio private network communication

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.
