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.

DMR private network communication implementation method, terminal, relay station and system

The present invention relates to communication technologies and provides a private network communication terminal and a method for realizing private network communication, In the invention, one private network communication can only be performed in one time slot with a fixed location in a DMR TDMA frame, so that other mobile communication terminals that do not participate in the private network communication can determine an unoccupied time slot in advance, thereby they can initiate a new private network communication with the unoccupied time slot.

Private network communication terminal and method for realizing private network communication

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.
