Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

FIG. 1 is a flowchart of a network switching method shown in an embodiment of the present disclosure. As shown in FIG. 1 , the network switching method applied to a mobile terminal includes the following steps:

S11. When the mobile terminal is triggered to switch from the first network to the second network, detect the network quality of the first network; wherein the system bandwidth of the second network is smaller than the system bandwidth of the first network;

S12. When it is detected that the network quality of the first network satisfies a preset network quality condition, enter a registration process of connecting to the first network and shielding the mobile terminal from supporting the communication of the second network from the network side.

In the embodiments of the present disclosure, the mobile terminal includes mobile electronic devices such as mobile phones, tablet computers, smart watches or smart glasses.

In step S11, if the mobile terminal is triggered to switch from the first network to the second network, the mobile terminal will detect the network quality of the first network to determine whether to perform a network switching action. Wherein, the system bandwidth of the second network is smaller than the system bandwidth of the first network. For example, when the mobile terminal uses the first network, the amount of data transmitted per unit time is better than that of the second network or the data transmission rate is better than that of the second network.

In the embodiments of the present disclosure, for example, the first network is a 3G or 4G network based on Long Term Evolution (Long Term Evolution, LTE), and the second network is a 2G network based on Global System for Mobile communications (Global System for Mobile communications, GSM).

FIG. 2 is an example diagram of a network environment of a mobile terminal in an embodiment of the present disclosure. As shown in FIG. 2 , the network environment 100 includes an LTE network coverage area 101, a GSM network coverage area 102, and a mobile terminal 103 in the common coverage area of the LTE network and the GSM network. . In the embodiments of the present disclosure, for example, the first network is a 4G network based on LTE technology, and the second network is a 2G network based on GSM technology. It will be connected to the 4G network and reside on the 4G network, but there are network optimization failures or network restrictions on the network side, and the mobile terminal may switch from the 4G network to the 2G network.

It should be noted that, in the embodiment of the present disclosure, it is not limited that the first network is 4G and the second network is 2G. For example, the first network may be 5G, and the second network may be 4G; the first network may be 4G, and the second network may be 3G; or the first network may be 5G, and the second network may be 2G, etc., which are not limited in this embodiment of the present disclosure.

When the mobile terminal accesses the preset cell of the first network, it may trigger the mobile terminal to switch from the currently connected first network to the second network. Two networks. The network restriction may be a restriction on the number of access users. For example, the network side restricts the number of access users within a preset range of the number of users in order to ensure the network transmission speed of the access users. When the network side determines that the number of users accessing the preset cell exceeds the number of preset user ranges, it may trigger the handover of the mobile terminal from the first network to the second network.

In addition, when the network optimization algorithm on the network side is abnormal, the network side may also send a switching instruction to the mobile terminal, thereby triggering the mobile terminal to switch from the first network to the second network.

In an embodiment, detecting the network quality of the first network includes:

Detecting the network quality of the first network based on a network diagnostic tool in the mobile terminal; or,

Detecting the network quality of the first network based on the service interaction status with the first network.

In this embodiment, the mobile terminal can detect the network quality of the first network based on a built-in network diagnostic tool, for example, the network diagnostic tool is an Internet packet explorer (Ping), a program for testing network connection volume. The mobile terminal can send a network diagnosis request to the server connected to the mobile terminal through the network diagnosis tool, and infer the current network quality based on the information returned by the server based on the sent network diagnosis request.

For example, the mobile terminal obtains network information such as the signal strength, signal-to-noise ratio, and bit error rate of the current first network based on the network diagnostic tool, thereby comparing the signal strength of the first network with the preset strength threshold, and the signal-to-noise ratio with the preset ratio The network quality of the first network is detected by comparing the bit error rate with the preset bit error rate and so on.

In addition, when the mobile terminal has service interaction with the first network, the network quality of the first network may also be detected through the service interaction status. Wherein, the service interaction between the mobile terminal and the first network is, for example, WeChat information interaction, web page browsing, or game control based on the first network, which is not limited in this embodiment of the present disclosure. When the mobile terminal detects the network quality of the first network through the service interaction status, the mobile terminal may determine whether the current interactive service can be carried out normally, for example, whether WeChat information can be sent or received normally, whether the webpage can be opened normally, game control Can it be executed etc.

In step S12, if the mobile terminal detects that the network quality of the first network satisfies the preset network quality condition, it will enter a registration process of connecting to the first network and shielding the mobile terminal from supporting the communication of the second network to the network side.

Wherein, the mobile terminal shields the ability of the mobile terminal to support the second network communication during the registration process. It may be that the mobile terminal carries information in the registration request to inform the network side that the mobile terminal does not support the second network communication capability; it may also be during the registration process. , the mobile terminal additionally sends a message to the network side to inform the network side that the mobile terminal does not support the second network communication capability.

When the mobile terminal registers with the network side, the mobile terminal may send a connection request to the network side; after receiving the connection request, the base station feeds back response information to the mobile terminal. After receiving the response information from the network side, the mobile terminal sends an acknowledgment message (Acknowledgment, ACK) indicating successful access, or a non-acknowledgment message (Negative ACKnowledgment, NACK) indicating access failure, thereby completing the registration process. After the mobile terminal successfully accesses the network side, it can perform download or upload data services.

It should be noted that, in the embodiment of the present disclosure, in step S12, a predetermined number of registrations may be set, so that when the mobile terminal fails to register with the first network for the first time, the success rate can still be increased through multiple registrations. Of course, if the mobile terminal fails for a predetermined number of times, it will switch to the second network so that the mobile terminal can work normally.

In related technologies, if a mobile terminal is located in an area covered by multiple networks and is triggered to switch from a high-bandwidth network to a low-bandwidth network, it is usually necessary to restart the mobile terminal or switch the flight mode manually when the user finds out. Try the terminal to re-search for a network with higher bandwidth and register. There are two problems in this method. One is that the mobile terminal will switch to a network with a lower bandwidth, and if the user does not find the network switch, the mobile terminal will work on a network with a smaller bandwidth, which is not enough for terminal users with data needs. Friendly; the second is that if the user finds the network switching, the user needs to manually operate, which is poor in intelligence, thus making the user experience bad.
