Specifically, referring to fig. 3, in a first aspect, a station attendant speaks using a console, 400M digital CIR and 450M analog CIR playback. When the voice stream A of the operation desk enters the voice/data processing and bridging unit, the unit judges that the voice needs to be simultaneously transmitted to the 400M digital CIR and the 450M analog CIR according to the established call type 'group call in the station'. The unit performs the following processing: (1) Mixing the voice streams entering the voice/data processing and bridging unit, and copying the voice streams after mixing into two parts; (2) The first voice stream B is packaged in an RTP message format, is transmitted to a base station, and activates the transmission of a downlink voice stream D of the base station by transmitting PTT signaling, so that 400M digital CIR can be heard, and the PTT signaling is transmitted to the base station after the transmission of the voice stream B is finished; (3) The second voice stream C is subjected to voice format conversion and segmentation so as to adapt to the interface of the 450M co-channel machine module, and the sending of the downlink voice stream E of the module is activated by sending PTT signaling so that the 450M analog CIR can be heard, and the PTT signaling is released to the module after the sending of the voice is finished. In summary, the processed voice stream is divided into two paths, one path is sent to the 400M digital CIR from the air interface via the base station, and the other path is sent to the 450M analog CIR from the air interface via the co-channel machine module of the 450M unit. The voice stream of the 400M digital CIR is converted into voice stream A- >, voice stream B- >, voice stream D, and the digital CIR plays after receiving the voice stream D; the voice stream of the 450M analog CIR is converted into voice stream A- > voice stream C- > voice stream E, and the 450M analog CIR plays after receiving the voice stream E.
In the second aspect, the driver speaks using a 400M digital CIR, and the station console and 450M analog CIR playback.
After the voice stream of 400M digital CIR is generated, the voice stream F generates a voice stream H through the base station, and when the voice stream H enters a voice/data processing and bridging unit, the unit judges that the voice needs to be simultaneously transmitted to a station operation console, 450M analog CIR and other 400M digital CIR according to the established call type 'group call in the station'. The unit performs the following processing: (1) Mixing the voice streams entering the voice/data processing and bridging unit, and copying the voice streams after mixing into three parts; (2) The first voice stream J is packaged in an RTP message format and is transmitted to an operation desk; (3) The second voice stream C is subjected to voice format conversion and segmentation so as to adapt to the interface of the 450M co-channel machine module, and the sending of the downlink voice stream E of the module is activated by sending PTT signaling so that the 450M analog CIR can be heard, and the PTT signaling is released to the module after the sending of the voice of the second voice stream C is finished; (4) The third voice stream B is packaged in RTP message format, loops back to the base station, and activates the transmission of the downlink voice stream D of the base station by transmitting PTT signaling, so that other 400M digital CIRs can hear, and the PTT signaling is released to the base station after the transmission of the voice is finished. In summary, the processed voice stream H is split into three, the first path is directly sent to the station console, the second path is sent to the 450M analog-type CIR, and the third path is sent to the other 400M digital-type CIR. The voice stream of the station operating platform is converted into voice stream F- >, voice stream H- >, voice stream J, and the station operating platform plays sound after receiving the voice stream J; the voice stream of the 450M analog CIR is converted into a voice stream F- >, a voice stream H- >, a voice stream C- >, a voice stream E, and the 450M analog CIR plays sound after receiving the voice stream E; the voice stream of the other 400M digital CIR is converted into voice stream F- >, voice stream H- >, voice stream B- >, voice stream D, and the other 400M digital CIR receives the voice stream D and plays the voice.
In the third aspect, 3. The driver speaks using 450M analog CIR, station console and 400M digital CIR playback.
After the voice stream of 450M analog CIR is generated, the voice stream G generates a voice stream I through the co-channel machine, and when the voice stream I enters a voice/data processing and bridging unit, the unit judges that the voice needs to be simultaneously transmitted to a station operation console and 400M digital CIR according to the established child phone type 'group call in the station'. The unit performs the following processing: (1) Mixing the voice streams entering the voice/data processing and bridging unit, and copying the voice streams after mixing into two parts; (2) The first voice stream J is packaged in an RTP message format and is transmitted to an operation desk; (3) The second voice stream B is packaged in RTP message format, and is sent to the base station, and the sending of the downlink voice stream D of the base station is activated by sending PTT signaling, so that 400M digital CIR can be heard, and the PTT signaling is released to the base station after the sending of the voice is finished. To sum up, the processed voice stream I is divided into two parts, one part is directly sent to the station operation console, and the other part is sent to the 400M digital CIR. The voice stream of the station operation platform is converted into voice stream G- >, voice stream I- >, voice stream J, and the station operation platform plays sound after receiving the voice stream J; the voice stream of the 400M digital CIR is converted into voice stream G- >, voice stream I- >, voice stream B- >, voice stream D, and the 400M digital CIR plays after receiving the voice stream D.
