Example four

In the four-channel mirror trunked mode, the integrated communication system includes at least one calling station 100, at least two base stations 12, and at least one receiving station 200, with at least two base stations 12 wirelessly ad-hoc with each other. In the four-channel mirror image trunking mode, a TDMA time division multiple access technology and a speech coding and decoding technology are adopted, time slots of one channel machine 20 of a base station 12 are alternately distributed according to a plurality of time slots M and a plurality of time slots N, the plurality of time slots M form a first channel, the plurality of time slots N form a second channel, each base station 12 comprises two channel machines 20, each channel machine 20 comprises two channels, each base station 12 comprises four channels, any one of the four channels uses a time slot Y of a control frequency as a control channel, and the rest three time slots correspond to three voice channels. The main differences from the third embodiment are: one time slot is selected as a control channel.

The specific working process is as follows: taking the first frequency as the control frequency, all the mobile stations 13 are in the waiting state at the first frequency, which is a preset frequency, and the first frequency is usually not consistent with the transceiving frequency used by the voice channel, the transceiving frequency of the voice channel can be regarded as the second frequency or other frequencies, and here, the first frequency is merely for convenience of description, and can be interpreted as a frequency suitable for serving as the control frequency. When at least one calling mobile station 100 needs to initiate a call request, a call application is first initiated to the control channel of any one base station 12 of the at least two base stations 12 in the time slot Y at the first frequency, after receiving the call application, the control channel allocates an idle channel as a voice channel and generates a channel allocation signaling according to the current channel occupation status of any base station 12, then any base station 12 sends the channel allocation signaling to all the mobile stations 13 by way of air interface simulcasting downlink signals, at least one calling mobile station 100 and at least one receiving mobile station 200 switch to the allocated voice channel after receiving the channel allocation signaling, at least one calling mobile station 100 communicates with at least one receiving mobile station 200 through any base station 12, when the call is over, all the stations 13 switch back to the control channel to continue waiting, and the allocated voice channel falls back to the idle state. Therefore, the mode has the characteristics that the base station can be compatible with a standard PDT (digital television) mobile station, can support the co-frequency simulcasting of four digital trunking channels, and effectively solves the problem that a control channel is required in trunking communication.

The multi-standard integrated communication system according to claim 2, wherein in a three-hop two-channel ad hoc network mode, the integrated communication system comprises at least one calling mobile station, at least one class a base station, at least one class B base station, and at least one receiving mobile station, wherein the mobile stations and the base stations all work by using a preset communication standard protocol, the base stations all work by using a low-frequency transceiver module, and the time slot 1, the time slot 3, and the time slot 5 constitute a first channel, and the time slot 2, the time slot 4, and the time slot 6 constitute a second channel;

the time slot M is configured to be any one of time slot 1, time slot 3 and time slot 5;

the time slot N is configured as any one of time slot 2, time slot 4 and time slot 6;

one calling mobile station in at least one calling mobile station sends an uplink signal at a low-band frequency, a low-band transceiver module of the A-type base station receives the uplink signal at a time slot M and then forwards the uplink signal at a time slot M +1, and the forwarded signal of the A-type base station is used as a link signal and a downlink signal; the low-frequency transceiver module of the B-type base station receives the uplink signal in a time slot M +1 and then forwards the uplink signal in a time slot M +2, the forwarded signal of the B-type base station is used as a link signal and a downlink signal, and at least one receiving station receives the downlink signal;

9. The multi-standard integrated communication system according to claim 2, wherein in a six to twelve channel mirror cluster mode, the integrated communication system comprises at least one calling station, a tandem exchange, a class a base station, a class B base station, and at least one receiving station; the base stations of the A type and the B type work by adopting a low-frequency band transceiver module and a high-frequency band transceiver module of two channels;

10. The multi-standard integrated communication system according to claim 2, wherein in a one-hop one-channel super communication mode, the integrated communication system comprises a mobile station, a base station, a tandem switch, and a dispatching station, wherein the mobile station and the base station are both in the super mode, and at this time, the base station needs to independently switch at least one low-band receiving module thereof to a high-sensitivity decoding mode;

the method comprises the steps that a mobile station located at a far end is adjusted to a super mode, the mobile station transmits an emergency modulation signal to a base station, a low-frequency-band receiving module of the base station receives the emergency modulation signal to decode, and then transmits the decoded signal to a channel controller, the channel controller uploads the decoded signal to a tandem switch, the tandem switch transmits the decoded signal to a calling station, and the dispatching station acquires the state of the mobile station located at the far end through the decoded signal.
