The network identifiers of the plurality of Wifi networks which have been connected to the terminal historically can be obtained by sorting based on historical connection data of the plurality of Wifi networks which have been connected to the terminal before the current time. The historical connection data includes at least one of a number of connections, a total connection duration, and a most recent connection time.
Optionally, when the common network identifier exists in the first Wifi environment information and the pre-stored second Wifi environment information, the Wifi network indicated by the common network identifier is determined as the target Wifi network, which includes but is not limited to the following two possible implementation manners.
In one possible implementation manner, when one common SSID exists in the first WiFi environment information and the second WiFi environment information, the WiFi network indicated by the common SSID is determined as the target WiFi network
In another possible implementation manner, when a plurality of common SSIDs exist in the first WiFi environment information and the second WiFi environment information, one common SSID is selected according to a selection policy, and a WiFi network indicated by the selected SSID is determined as a target WiFi network.
The selection strategy comprises selecting the common SSID with the largest signal strength, or selecting the first scanned common SSID, or selecting the common SSID positioned at the first according to the sequence of the stored network identifications, or receiving the common SSID selected by the user. The present embodiment does not limit the setting of the selection policy.

Optionally, when the terminal scans a Wifi network for the first time, the signal strength of the Wifi network is obtained, the signal strength is recorded as the maximum signal strength of the Wifi network, and the network identifier and the maximum signal strength of the Wifi network are stored in a key value pair form. After the storage is finished, when the terminal scans the Wifi network again, if the real-time signal intensity of the Wifi network acquired by the terminal is higher than the stored maximum signal intensity, the acquired real-time signal intensity is assigned to the maximum signal intensity, that is, the maximum signal intensity is updated to the acquired real-time signal intensity.
It should be noted that, the process of determining the connection threshold by the terminal according to the historical maximum signal strength of the target Wifi network may refer to relevant details in the following embodiments, which are not described herein first.
Optionally, the connection threshold is a threshold used to indicate that the terminal can be stably connected to the target Wifi network. The terminal can be stably connected with the target Wifi network, and the network switching connection times of the terminal in a specified time period after the terminal is connected with the target Wifi network are smaller than a switching threshold value.
The specified time period and the handover threshold may be user-defined or terminal default settings. This embodiment is not limited thereto.
And step 203, connecting the target Wifi network when the real-time signal intensity is greater than the connection threshold value.

In summary, in the embodiment, when the terminal scans the target Wifi network, the real-time signal intensity of the target Wifi network and the connection threshold corresponding to the target Wifi network are obtained, and since the connection threshold is a threshold associated with the historical maximum signal intensity of the target Wifi network, the terminal connects to the target Wifi network when the real-time signal intensity is greater than the connection threshold, the probability that the connection speed of the terminal is slow due to too low signal intensity of the Wifi network to be connected is reduced, and the connection effect of the Wifi network is ensured.

Optionally, because the connection threshold is smaller than the historical maximum signal strength, when the real-time signal strength is greater than the historical maximum signal strength, it means that the target Wifi network meets the condition that the real-time signal strength is greater than the connection threshold, and the step of obtaining the connection threshold is not required to be executed again, and the target Wifi network is connected.
Optionally, when the real-time signal strength of the target Wifi network acquired by the terminal is greater than the historical maximum signal strength, the real-time signal strength of the target Wifi network is assigned to the maximum signal strength, that is, the maximum signal strength is updated to the acquired real-time signal strength.

That is, the connection threshold is the ratio of the historical maximum signal strength to the first connection value, and the connection threshold is less than the historical maximum signal strength.

In one illustrative example, when the terminal scans to the target Wifi network, the SSID "Wifi-001" and the real-time signal strength "-35 dbm" of the target Wifi network are obtained. And the terminal acquires the historical maximum signal strength of the target Wifi network of-30 dbm according to the second corresponding relation shown in the table I, the real-time signal strength of-35 dbm is smaller than the historical maximum signal strength of-30 dbm, the terminal determines the ratio of the historical maximum signal strength of-30 dbm to the first connection numerical value of 0.8 as a connection threshold value of-37.5 dbm, and when the terminal judges that the real-time signal strength of-35 dbm is larger than the connection threshold value of-37.5 dbm, the target Wifi network is connected.

Illustratively, when the real-time signal intensity of the target Wifi network is the scanned maximum signal intensity, the difference between the maximum signal intensity and the minimum signal intensity is greater than the second difference threshold, and the real-time signal intensity of the target Wifi network is greater than the connection threshold, the target Wifi network is connected.
It should be noted that the second difference threshold is set by a user or by default in the terminal.
In another possible implementation manner, the terminal acquires the historical connection power and/or the historical connection time of the scanned at least two Wifi networks respectively corresponding to the Wifi networks; and when the real-time signal intensity of the target Wifi network is greater than the connection threshold and meets the second connection condition, connecting the target Wifi network.
The second connection condition comprises that the historical connection success rate of the target Wifi network is highest in the historical connection power corresponding to the at least two Wifi networks, and/or the historical connection time consumption of the target Wifi network is shortest in the historical connection time consumption corresponding to the at least two Wifi networks.

Optionally, the historical connection time consumption is an average connection time consumption from the beginning of connecting to the target Wifi network to the successful connection of the terminal in history. And the historical connection time is used for indicating the connection speed of the terminal connected with the Wifi network. The historical connection time consumption and the connection speed are in a negative correlation relationship.
