Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
When the mobile terminal is switched from the public network to the private network, the modem is restarted at the mobile terminal, and the obtained user data is processed and applied during private network communication. When the public network is switched to the private network, the private network faces to a special application environment, so that user data used for private network communication is generally stored in the cloud. When the mobile terminal is switched to the private network, after the modem is restarted, user data only needs to be directly called at the cloud end, so that the data connection between the terminal and the private network is directly established. Unlike the mode of switching from the public network to the private network, when the communication network of the terminal is switched from the private network to the public network, it is necessary to acquire user data from the SIM card of the terminal. Therefore, in the mode of switching the public network to the private network, after the modem is restarted, the terminal needs to load the SIM card to acquire the user data, and can continue to establish the data connection with the public network after acquiring the user data stored in the SIM card. When the mobile terminal is switched back and forth between the public network and the private network, the mobile terminal needs to load the SIM card first when the private network is switched to the public network, the SIM card is loaded for many times, so that the die cutting time for switching from the private network to the public network is prolonged, and the mobile terminal cannot be kept on line continuously.
In view of the above problems, an embodiment of the present application provides a method for improving the public and private network handover performance, which is mainly applied to a mobile terminal, and as shown in fig. 1, the detailed steps are as follows:
and S11, selecting the public network or the private network as the current communication network of the terminal according to the signal quality of the public network or the private network.
In this step, a communication network is searched through a public network module and a private network module which are arranged in the mobile terminal, and the signal quality of the currently searched communication network is obtained, wherein the signal quality comprises signal strength. And taking the communication network with better detected signal strength as the current communication network of the terminal. And when only the signal intensity of any one communication network of the public network or the private network is detected, directly selecting the public network or the private network as the current communication network.
And S12, loading the SIM card to obtain the user data when the current communication network is switched to the public network for the first time.
In this step, when the current communication network is a private network and the signal quality of the public network is detected to be higher than that of the current communication network of the terminal for the first time, the mobile terminal restarts the modem, loads the SIM card for the first time, and reads the user data in the SIM card.
After the user data in the SIM card is acquired, the mobile terminal can be switched from the private network to the public network, and establishes data connection with the public network by using the user data.
And S13, storing the acquired user data for use when the current communication network is switched to the public network again.
In this step, when the mobile terminal is switched from the private network to the public network for the first time, the user data read from the SIM card loaded for the first time is stored in the mobile terminal. When the current communication network of the mobile terminal is a private network and the private network is switched to the public network again, the user data stored in the mobile terminal is called, the data connection with the public network is directly established by using the user data, and the mobile terminal can be switched to the public network again from the private network.
Based on the embodiment of the application, when the current communication network of the mobile terminal is switched from the private network to the public network for the first time, the SIM card is loaded, the read user data in the SIM card is stored, and when the current communication network of the mobile terminal is switched from the private network to the public network again, the data connection with the public network is directly established, the SIM card is not repeatedly loaded, the time delay of the mode switching of the public and private networks of the mobile terminal is reduced, and the use experience of a user is improved.
Further, the method further comprises:
and loading system variables after starting up, wherein the initial values of the system variables are first numerical values which represent that the SIM card needs to be loaded, and the system variables are set to second numerical values which represent that the SIM card does not need to be loaded when the user data is acquired by loading the SIM card.
When the mobile terminal is started up for the first time, the mobile terminal automatically loads the system variable, the initial value of the system variable is a first numerical value, and the first numerical value indicates that the current mobile terminal has not been switched from the private network to the public network, that is, the current mobile terminal has not been loaded with the SIM card. On the contrary, if the mobile terminal is started up and switched from the private network to the public network for the first time, that is, the mobile terminal has loaded the SIM card and established data connection with the public network through the acquired user data, and the current mobile terminal has been switched from the private network to the public network, the system variable value is automatically changed to the second value, and the second value indicates that the current mobile terminal has been switched from the private network to the public network, that is, the current mobile terminal has loaded the SIM card and has stored the user data in the SIM card. Wherein the first numerical value is different from the second numerical value to distinguish different physical meanings represented by the first numerical value and the second numerical value.
Further, after the system variables are loaded, the method further includes:
reading system variables when the current communication network is switched to the public network; and judging whether to load the SIM card according to the current value of the system variable.
After the system variables are loaded and the different physical meanings represented by the first numerical value and the second numerical value are determined, the mobile terminal first reads the system variables and judges whether the SIM card needs to be loaded according to the read current values of the system variables each time the current communication network of the mobile terminal is switched from the private network to the public network.
As shown in fig. 2, a detailed flowchart of a method for improving the public/private network handover performance according to an embodiment of the present application is shown, and the detailed steps are as follows:
s21, the mobile terminal is started, system variables are loaded, the signal quality of the current public network and the signal quality of the current private network are compared, when the signal quality of the public network is stronger than that of the private network, the current communication network of the mobile terminal is determined to be switched to the public network, and the modem is restarted;
s22, after the modem is restarted, judging the current value of the system variable;
s23, when the current value of the system variable is the first value, loading the SIM card, modifying the current value of the system variable from the first value to the second value, and storing the user data obtained by loading the SIM card;
and S24, when the current value of the system variable is a second value, the current mobile terminal is not switched from the private network to the public network for the first time, namely the SIM card is loaded, and then the data connection with the public network is directly established.
In the mutual-aid mode of the public and private networks, when the mobile terminal is automatically switched to the public network from the current private network, the modem is restarted, and when data connection with the public network is needed, whether an SIM card is loaded before is judged, namely whether the current value of a system variable is changed is judged, and after the SIM card is loaded before is judged, the data connection with the public network is directly established; if the SIM card is not loaded before, the operation of loading the SIM card is executed firstly, and then the data connection with the public network is established. Judging whether the mobile terminal loads the SIM card mainly by judging the current value of the loaded system variable. The system variable is set to a first value, such as an initial value true, each time the terminal is powered on. After the mobile terminal is started up each time, when data connection with a public network is established for the first time, the SIM card is loaded once, and then the current value of the system variable is modified to a second numerical value after the loading is successful, such as false. In the mutual-aid mode of the public and private networks, when a terminal automatically switches from the private network to the public network and needs to establish data connection and load an SIM card, the terminal firstly judges whether the current value of a system variable of the SIM card needs to be loaded or not. When the current value is false, it is indicated that the SIM card has been successfully loaded before, and at this time, the data connection with the public network can be directly established without repeated loading. When the current value is true, the SIM card is not loaded before the current value is indicated, and at the moment, the SIM card needs to be loaded firstly and then the data connection needs to be established, so that the time delay of establishing the data connection of the public network when the private network is switched to the public network every time can be reduced, and the automatic die cutting performance is improved.
