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

摘要

terminal and private digital mobile radio network communication system, and, method of implementation for particular digital mobile radio communication a communication terminal, a communication system, and a method of realisation for a special dmr network are provided, in order to determine an idle time interval in advance and use the idle time interval to initiate a special new network communication. the dmr special network communication terminal includes a communication module to receive and transmit a special dmr network communication; a synchronization module,to monitor a dmr synchronization sketch and establish synchronization with the sketch, and determine the current time interval based on the dmr synchronization sketch, thereby locking on the previously allocated communication time range; a control communication module, to receive and transmit special network dmr communication within the pre-allocated time range. the special network communication terminal is limited and in order to communicate only in the pre-allocated communication time range, so it is ensured that the same special network communication is transmitted on the same team all the time. Therefore,other terminals may stop at idle time intervals in advance in order to initiate new special network communications, so the special dmr feature is quite used.
