Public network communications generally refer to wireless communications operated by telecommunications carriers, including 4G, 3G, GPRS/GSM, CDMA, and satellite communications, among others. The public network is a commercial wireless network with mature technology, stable performance, large user capacity and low speed. Because the private network construction cost is high and the construction period is long, the coverage area of the private network is limited, and the public network is generally used for coverage extension of the private network. When the area with good private network signals is in the private network link mode, the cluster terminal is switched to the public network link mode in the area with poor private network signals or no private network signals, and therefore the continuous communication state of the terminal is kept. However, after the trunking terminal switches the link mode, the trunking terminal needs to re-register to continue executing the service, which may result in service interruption or data loss.

Fig. 1 is an architecture diagram of a network link switching system of a trunking terminal according to an embodiment of the present invention, where the link switching system of the trunking terminal in this embodiment includes: the system comprises a cluster server, a cluster terminal, a public network and a private network. The cluster server is connected with the cluster terminal through a private network and/or a public network.
The cluster server is a cluster service server with a Push-to-Talk over Cellular (POC) function.
The cluster terminal is a terminal device joining a cluster network. The cluster terminal has double-card and double-pass functions. 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 simultaneously access the private network link and the public network link, and the cluster terminal simultaneously uses the public network and the private network for service data transmission.

As shown in fig. 2, the method of the present embodiment includes the following steps:
step S201, under the link mode of the private network, the network signal quality of the private network is detected.
In the embodiment of the invention, the cluster terminal preferentially uses the private network link because the private network has the advantages of autonomous control, no external limit, safety, reliability and the like. And detecting the network signal quality of the private network in the private network link mode. The network signal quality may be detected in real time, or may be detected every preset time, for example, every 2 seconds. In the private network link mode, a private network modem of the cluster terminal is turned on, a public network modem is turned off, 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.
Step S202, if it is detected that the network signal quality of the private network meets a first preset condition, a public network modem of the trunking terminal is started, and the current link mode is switched from the private network link mode to a public and private network cooperative link mode.
In the embodiment of the invention, the network signal quality of the private network meets the first preset condition, which indicates that the link quality of the private network is poor, the cluster service cannot be independently completed, and the private network and the public network are required to cooperatively perform the cluster service. At the moment, the public network modem of the cluster terminal is started, a first request for using the public network link is reported to the cluster server, the cluster terminal is enabled to simultaneously access the public network link and the private network link by the server according to the first request, and the current link mode is switched from the private network link mode to the public and private network cooperative link mode. That is, in the mode of the public-private network cooperative link, 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 for service data transmission.
Step S203, if it is detected that the private network does not transmit the data packet of the current service within 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.
In the embodiment of the invention, the private network is continuously detected in the public and private network cooperative link mode. When the cluster terminal executes the service, whether a data packet of the current service transmitted by a private network link is received or not is detected. And judging whether the private network link transmits the data packet of the current service or not according to the port number and the ip address corresponding to the current service. In a first preset time, the data packet of the current service which is not transmitted by the private network 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 trunking terminal is closed, the trunking terminal is only accessed to the public network link, and the public network is used for service data transmission. Namely, in the public network link mode, the public network modem is turned on, the private network modem is turned off, the cluster terminal accesses the public network link, and the public network is used for service data transmission. The first preset time may be set empirically, for example, the first preset time is 10 seconds.
The embodiment of the invention detects the network signal quality of the private network in the private network link mode, switches the current link mode from the private network link mode to the public and private network cooperative link mode when the network signal quality of the private network meets a first preset condition, and switches the current link mode from the public and private network cooperative link mode to the public network link mode if the situation that the private network does not transmit the data packet of the current service is detected within a first preset time, thereby avoiding service interruption or data loss in the network switching process.

Specifically, the control module receives the working frequency point information of the private network input by the user, and configures the working frequency point of the private network in the public network modem according to the working frequency point information of the private network input by the user.
Step S302, if the public network modem detects the network signal of the private network, the quality of the network signal of the private network detected by the public network modem is obtained.
Step S303, if the network signal quality of the private network meets a second preset condition, the private network modem is turned on again, and the current link mode is switched from the public network link mode to the public and private network cooperative link mode.
In the embodiment of the invention, when the public network modem detects the network signal of the private network and indicates that the cluster terminal is in the coverage range of the private network, the quality of the network signal of the private network detected by the public network modem is obtained.
And when the network signal quality of the private network meets a second preset condition, indicating that the cluster terminal can use the private network link, starting the private network modem of the cluster terminal, reporting a second request for using the private network link to the cluster server, enabling the cluster terminal to simultaneously access the public network link and the private network link by the server according to the second request, and switching the current link mode from the public network link mode to the public and private network cooperative link mode.
In the embodiment of the invention, the private network is detected through the public network modem in the public network link mode, and when the network signal of the private network is detected and the quality of the network signal of the private network meets the second preset condition, the link mode is switched to the public and private network cooperative link mode instead of being directly switched to the private network link mode, so that service interruption or data loss in the network switching process can be further avoided.

And in a second preset time, the packet loss rate of the private network is 0, the packet loss rate of the private network indicates that the contribution rate of the private network to the current service is 100%, the private network can independently complete the current service, at this time, the public network modem of the cluster terminal is closed, the cluster terminal is only accessed to a private network link, and the private network is used for service data transmission. Namely, in the private network link mode, the private network modem is turned on, the public network modem is turned off, the cluster terminal accesses the private network link, and the private network is used for service data transmission. The second preset time may be set empirically, for example, the second preset time is 10 seconds.
