Public network communications generally refer to wireless communications operated by telecommunications operators, including 4G, 3G, GPRS/GSM, CDMA, satellite communications, and the like. Public networks are commercial wireless networks with mature technology, stable performance, large user capacity, and low rates. Because of the high construction cost and long construction period of the private network, the coverage area of the private network is limited, and the public network is generally utilized for coverage extension of the private network. When the private network signal is good, the cluster terminal is in the private network link mode, and when the private network signal is poor or no private network signal is in the private network link mode, the cluster terminal is switched to the public network link mode, so that the continuous communication state of the terminal is maintained.

The cluster terminal is provided with a public network modem (modem), a private network modem and a control module. The control module is used for controlling the on and off of the public network modem and the private network modem and detecting the network quality of the current access network of the cluster terminal. When the public network modem is started and the private network modem is closed, the cluster server enables the cluster terminal to access a public network link, and the cluster terminal uses the public network to transmit service data; when the private network modem is started and the public network modem is closed, the cluster server enables the cluster terminal to access a private network link, and the cluster terminal uses the private network to transmit service data; when the public network modem and the private network modem are simultaneously started, the cluster server enables the cluster terminal to be simultaneously accessed into the private network link and the public network link, and the cluster terminal is simultaneously used for carrying out service data transmission by using the public network and the private network.

in step S201, in the private network link mode, the network signal quality of the private network is detected.
In the embodiment of the application, the private network has the advantages of autonomous control, no external limitation, safety, reliability and the like, and the trunking terminal preferentially uses the private network link. And in the private network link mode, detecting the network information quality of the private network. The network signal quality may be detected in real time or may be detected every preset time, for example, every 2 seconds. In private network link mode, the private network modem of the cluster terminal is turned on, the public network modem is turned off, the cluster server enables the cluster terminal to access the private network link, and the cluster terminal uses the private network to transmit service data.
Step S202, if the network signal quality of the private network is detected to meet the first preset condition, a public network modem of the cluster terminal is started, and the current link mode is switched from the private network link mode to a public private network cooperative link mode.
In the embodiment of the application, the network signal quality of the private network meets the first preset condition to indicate that the link quality of the private network is poor, the trunking service can not be independently completed, and the private network and the public network are required to cooperatively carry out the trunking service. At this time, a public network modem of the cluster terminal is started, a first request for using a public network link is reported to a cluster server, and the server enables the cluster terminal to access the public network link and the private network link simultaneously according to the first request, and switches the current link mode from the private network link mode to the public private network cooperative link mode. That is, in the public-private network cooperative link mode, when the public network modem and the private network modem are simultaneously turned on, the cluster server enables the cluster terminal to simultaneously access the private network link and the public network link, and the cluster terminal simultaneously uses the public network and the private network to perform service data transmission.
Step S203, if the private network is detected not to transmit the data packet of the current service in the first preset time, the private network modem of the cluster terminal is turned off, and the current link mode is switched from the public private network cooperative link mode to the public network link mode.

And when the cluster terminal executes the service, detecting whether a data packet of the current service transmitted by the private network link is received or not. Judging whether the private network link transmits the data packet of the current service or not through the port number and the ip address corresponding to the current service. And in the first preset time, the private network does not transmit the data packet of the current service, and indicates that the contribution rate of the private network to the current service is zero in the first preset time, at this time, the private network modem of the cluster terminal is closed, and the cluster terminal only accesses the public network link and uses the public network to transmit the service data. Namely, in the public network link mode, the public network modem is turned on, the private network modem is turned off, the cluster terminal is accessed to the public network link, and the public network is used for transmitting service data. The first preset time may be empirically set, for example, the first preset time is 10 seconds.

3. A network link switching device of a cluster terminal, comprising:
the detection module is used for detecting the network signal quality of the private network in a private network link mode;
the switching module is used for starting a public network modem of the cluster terminal and switching the current link mode from the private network link mode to a public private network cooperative link mode if the network signal quality of the private network is detected to meet a first preset condition; wherein, the public network modem is configured with the working frequency point of the private network; if the private network does not transmit the data packet of the current service in the first preset time, closing the private network modem of the cluster terminal, and switching the current link mode from the public private network cooperative link mode to the public network link mode; the public network modem detects the network signal of the private network and acquires the network signal quality of the private network detected by the public network modem; if the network signal quality of the private network meets a second preset condition, starting the private network modem again, and switching the current link mode from a public network link mode to a public private network cooperative link mode; if the packet loss rate of the private network is detected to be 0 in the second preset time, the public network modem is closed, and the current link mode is switched from the public private network cooperative link mode to the private network link mode.
4. A network link switching device of a cluster terminal, comprising: at least one processor and memory;
the memory stores computer-executable instructions;
the at least one processor executing computer-executable instructions stored in the memory causes the at least one processor to perform the network link switching method of a clustered terminal as claimed in any one of claims 1 to 2.
5. A computer readable storage medium, wherein computer executable instructions are stored in the computer readable storage medium, which when executed by a processor, implement the network link switching method of a cluster terminal according to any one of claims 1 to 2.
