Digital cluster communication server, system and method thereof

Abstract

The invention discloses a digital cluster communication server, system and method. The digital cluster communication method comprises the following steps: S1) receiving a talking right request signal from a terminal which requests for the talking right; S2) judging whether to distribute the talking right to the terminal and generating a judgment result, judging whether the talking right request signal is a talking right application signal or a voice signal, performing step S3 if the talking right request signal is the talking right application signal, and performing step S4 if the talking right request signal is the voice signal; S3) generating a talking right authorizing signal according to the judgment result, sending the talking right authorizing signal to the terminal and guiding the terminal to send or not to send the voice signal according to the talking right authorizing signal; and S4) choosing to transmit or abandon the received voice signal according to the judgment result. By using the digital cluster communication method provided by the invention, the terminals which support the one-key authorizing system and the terminals which do not support the one-key authorizing system can be normally used in the digital cluster communication system.

Description

technical field [0001] The invention relates to the technical field of private network communication, in particular to a digital trunking communication server, a communication system and a communication method thereof. Background technique [0002] The standard DMR (Digital Mobile Radio, digital mobile radio) trunking terminal does not support the PTT (Push-to-talk, push-to-talk) authorization mechanism, that is, the trunking terminal sends voice directly, regardless of the digital trunking communication server (or base station) Whether to authorize forwarding. The PDT (Professional Digital Trunking, dedicated digital trunking) terminal supports the PTT authorization mechanism, that is, this kind of trunking terminal needs to jointly complete the speaking right through the handshake mode of the speaking right application signaling (such as P_MAINT) and the speaking right granting signaling (such as P_PROTECT). The management function of the terminal, only after being grante...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a kind of cluster terminal that supports PTT authorization mechanism and PTT authorization mechanism at the same time, aiming at the defect that the existing communication system cannot be compatible with the trunking terminal that supports the PTT authorization mechanism and the trunking terminal that does not support the PTT authorization mechanism. Digital trunking communication server, communication system and communication method thereof
