摘要： A communication terminal, a communication system and a realization method for a DMR special network are provided, in order to determine an idle time slot beforehand and use the idle time slot to initiate a new special network communication. The DMR special network communication terminal includes a communication module, for receiving and transmitting a DMR special network communication; a synchronization module, for monitoring a DMR synchronization drawing and establishing synchronization with the drawing, and determining the current time slot based on the DMR synchronization drawing, hereby locking the beforehand allocated communication time slot; a control communication module, for receiving and transmitting the DMR special network communication in the beforehand allocated time slot. The special network communication terminal is limited and so as to only communicate in the beforehand allocated communication time slot, so it is insured that the same special network communication is transmitted in the same time slot all the time. Therefore, the other terminals may lock idle time slots beforehand and so as to initiate new special network communications, thereby the DMR special resource is used enough.

摘要： Disclosed are a call collision processing method, a terminal and a transfer platform. The method comprises: a terminal sending an access request to a transfer platform, wherein the access request comprises a preset number of access request bursts; the terminal monitoring the channel state of the transfer platform, and judging whether the transfer platform transfers the access request bursts of the present terminal within a preset monitoring time: if the transfer platform transfers the access request bursts of the present terminal at least two continuous times within the preset monitoring time, then the terminal continues to send a following burst to the transfer platform, and if the transfer platform transfers access request bursts of other terminals at least two continuous times within the preset monitoring time, then the terminal terminates sending the following burst to the transfer platform. Such a solution can solve the call collision which is possibly generated among a plurality of terminals.
