And if the judgment result is that the switching is needed, the main controller evaluates other MS patch cards according to the switching strategy and screens one or more target MS patch cards. And then, determining the target switching MS patch card according to the comparison result of the operation state parameter of the target MS patch card and the index threshold value, switching the communication connection to the target MS patch card, and cutting off the communication connection of the default MS patch card. The switching strategy is selected according to different indexes (signal intensity, time delay and the like), and the MS patch card with the strongest network signal intensity and the shortest time delay is preferentially selected, or the MS patch card with the network signal intensity exceeding a preset intensity threshold and the longest duration is selected.
The embodiment provides a card cutting control method of a high-reliability integrated circuit, which adopts a three-network-in-one technology, can automatically switch to network injection of other operators under the condition that a network signal of a certain operator is not good or no network coverage exists, and solves the problem that network injection cannot be performed due to the fact that a single network signal is not enough in coverage and a formed network is black. The plurality of carrier patch cards (MS cards) are integrated together through the logic circuit, and the specific cards are selected for network injection in the process of network injection of the modules by combining the functions of the communication modules. The selected logic is managed by the application layer and the selected actions are performed by the MCU.

The algorithm chip is in butt joint with the upper communication module, so that a mechanism for transmitting SIM card communication instructions is realized. When the communication module performs network injection, judging whether the current network is available according to the selected strategy. And if the SIM card is not available, switching to another SIM card for network injection.

The MS patch card can be automatically switched to one with better signal strength or shorter delay, thereby providing a more stable and faster network connection.
When the default MS patch card fails or the running state parameter is lower than a preset index threshold, the main controller can judge and switch connection to other target MS patch cards. The switching can realize rapid fault recovery, reduce the system downtime and improve the availability and fault tolerance of the system. By selecting the MS patch card with the strongest signal strength and shortest time delay or the MS patch card with the longest duration reaching the preset strength threshold, the technical scheme can provide better user experience. When the user uses the network service, the user can enjoy more stable and faster data transmission, reduce delay and jamming phenomenon, and improve user satisfaction. By switching connection to the target MS patch card, the technical scheme can select the optimal MS patch card for data transmission according to the comparison result of the operation state parameter and the index threshold value. Thus, network resources can be effectively utilized, and the overall performance and efficiency of the network are improved.
On the other hand, the MS patch card switching strategy and the switching mode have the following technical effects:
first, optimized selection of a switching strategy: different switching strategies are described in the schemes, including selecting the MS patch card with the strongest signal strength and the shortest delay, or selecting the MS patch card with the signal strength exceeding the preset strength threshold and the longest duration. By the optimized selection of the switching strategies, the stability and the performance of the network connection can be improved. For example, selecting the MS patch card with the strongest signal strength may provide better signal coverage and transmission quality, and selecting the MS patch card with the shortest delay may reduce delay in data transmission.
Second, performance improvement of fast switching connection: in the scheme, the main controller switches the communication connection to the target switching MS patch card according to the judging result, and cuts off the communication connection of the default MS patch card. The rapid switching connection mode can greatly reduce the delay time of switching and improve the response speed and the user experience of the system. The user can switch from the default MS patch card to the target MS patch card without perception, so that the continuity and stability of data transmission are ensured.
Third, comparison optimization of the operating state parameters and the index threshold: the scheme describes that the operation state parameters of the target MS patch card are acquired and compared with the index threshold value to determine the target switching MS patch card. Through such comparative optimization, a target MS patch card whose operating state parameter meets or exceeds the index threshold may be selected to ensure that the MS patch card switched to has good operating state and performance. Therefore, the MS patch card with poor performance can be prevented from being selected to be switched, and the overall system performance is improved.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
