Abstract
The present invention relates to private network communication techniques, and provides a DMR private network communication terminal, communication system, and an implementation method thereof. 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.

A Digital Mobile Radio (DMR) private network communication terminal, adapted to implement DMR private network communication in direct mode, comprising:
- a communication module, adapted to receive a DMR synchronization pattern, and to receive and transmit DMR private network communication in a pre-assigned time slot of the DMR private network communication terminal;
- wherein, the DMR private network communication terminal further comprises:
- a synchronization module, adapted to:
- determine a time slot which is occupied by the received DMR private network communication according to the DMR synchronization pattern;
- establish synchronization with the received DMR synchronization pattern according to the time slot which is occupied by the received DMR private network communication and the pre-assigned time slot of the DMR private network communication terminal;
- lock the pre-assigned time slot of the DMR private network communication terminal;
- and
- control the communication module to respond to the DMR private network communication in the pre-assigned time slot of the DMR private network communication terminal.
A Digital Mobile Radio (DMR) private network communication system, comprising at least:
- a first DMR private network communication terminal;
- and
- a second DMR private network communication terminal;
- wherein, both the first DMR private network communication terminal and the second DMR private network communication terminal listen to a DMR synchronization pattern to establish synchronization according to a pre-assigned time slot of the first DMR private network communication terminal and the second DMR private network communication terminal, and thereby distinguishing each time slots;
- the first DMR private network communication terminal locks the pre-assigned time slot if the pre-assigned time slot is an idle time slot, and initiates DMR private network communication to the second DMR private network communication terminal in the pre-assigned time slot;
- and
- the second DMR private network communication terminal receives the DMR private network communication, determines the pre-assigned time slot which is occupied by the DMR private network communication, and responds to the DMR private network communication in the pre-assigned time slot.
An implementation method for Digital Mobile Radio (DMR) private network communication, adapted to implement DMR private network communication in direct mode, comprising:
- listening to, by a DMR private network communication terminal, a DMR synchronization pattern;
- determining, by the DMR private network communication terminal, a time slot which is occupied by the DMR private network communication upon receiving the DMR private network communication;
- establishing, by the DMR private network communication terminal, synchronization with the DMR synchronization pattern according to the time slot which is occupied by the received DMR private network communication and a pre-assigned time slot of the DMR private network communication terminal;
- and responding to the DMR private network communication in the pre-assigned time slot.
