FIG. 2 is a schematic flowchart of a method for selecting a WiFi hotspot provided by an embodiment of the present invention. The method for selecting a WiFi hotspot includes S201 to S203:

S201. The terminal device acquires the scanned connection parameters of at least one accessible WiFi hotspot.

In the embodiment of the present invention, the above connection parameters include historical connection parameters of each WiFi hotspot within a predetermined time period, and the historical connection parameters of each WiFi hotspot include the total number of times the WiFi hotspot has been successfully connected and each time the WiFi hotspot is successfully connected of user usage parameters.

Optionally, in this embodiment of the present invention, the user usage parameters for each successful connection to the WiFi hotspot include: the network traffic generated by the WiFi hotspot and the connection time during which the network traffic generated by the WiFi hotspot is greater than 0.

In the embodiment of the present invention, the above-mentioned accessible WiFi hotspots are accessible WiFi hotspots currently scannable by the terminal device. Exemplarily, the accessible WiFi hotspots in this embodiment of the present invention generally include two types: one is free WiFi hotspots, such as: free WiFi hotspots provided by operators, free WiFi hotspots provided by merchants, and WiFi hotspots shared by friends. , one is the WiFi hotspot connected to the terminal device.

Exemplarily, the above-mentioned free WiFi hotspots also include two types: one is a free password-free WiFi hotspot, and the other is a free encrypted WiFi hotspot. It should be noted that although the above-mentioned free encrypted WiFi hotspot requires a password, if the password of the WiFi hotspot can be obtained by the terminal device or the user, the encrypted WiFi hotspot can be considered as a free WiFi hotspot. For the WiFi hotspot connected by the terminal device, after the user manually enters the password to connect, the terminal device will store the password, so that when the terminal device scans the WiFi hotspot again, the terminal device can directly access the WiFi hotspot. Therefore, For the WiFi hotspot that the terminal device has connected to, it can also be considered as an accessible WiFi hotspot.

Further, all data stored in the cloud database can be periodically (updated at a fixed time every day, that is, only the usage data of each user using WiFi hotspots within one day is stored in the cloud database) or aperiodic (according to the administrator's instruction for passive update) to update.

Optionally, in this embodiment of the present invention, S201 specifically includes the following steps:

S201a, the terminal device obtains a list of WiFi hotspots.

Determine whether the current WiFi hotspot is an accessible WiFi hotspot.

In an example, WiFi hotspots are usually divided into two categories, one is home WiFi hotspots, and the other is public WiFi hotspots. Since home WiFi hotspots generally have faster network speeds and better user experience, the present invention The embodiment may exclude all home WiFi hotspots in the WiFi hotspot list, and then use the remaining public WiFi hotspots as currently accessible WiFi hotspots to further acquire connection parameters of these public WiFi hotspots. Exemplarily, since a public WiFi hotspot is usually connected by multiple people at the same time, this embodiment of the present invention can determine whether the WiFi hotspot is connected by determining whether the number of connections of the WiFi It is a public WiFi hotspot. If yes, it is determined that the WiFi hotspot is an accessible WiFi hotspot. If not, it is determined that the WiFi hotspot is an inaccessible WiFi hotspot.

Second possible implementation:

Exemplarily, S202 specifically includes the following steps:

S202b, the terminal device performs the following operations for each WiFi hotspot in the at least one WiFi hotspot:

Step D: the terminal device according to the total number of times N of the WiFi hotspot, the network traffic generated by the WiFi hotspot each time the WiFi hotspot is successfully connected, and the connection time that the network traffic generated by the WiFi hotspot is greater than 0 and the preset formula, Calculate the connection weight β of the WiFi hotspot.

Further optionally, the above a+b=1.

Further optional, since users generally have relatively high requirements for network speed, b>a can be set.

It should be noted that the above-mentioned _{Go and T 0 can} be flexibly set according to actual user scenarios, which are not limited in the present invention.

For example, assuming the above T ₀ =10min, _Go =10M, it means that a certain WiFi hotspot generates network traffic for more than 10min after a certain successful connection, it means that the WiFi hotspot is an available WiFi hotspot, and a certain WiFi hotspot is an available WiFi hotspot. When the network traffic generated after a WiFi hotspot is successfully connected exceeds 10M, it means that the WiFi hotspot is an available WiFi hotspot.

The corresponding formula is:

S203: The terminal device selects a target WiFi hotspot from at least one WiFi hotspot for network connection according to the connection weight of each WiFi hotspot.

In the embodiment of the present invention, after obtaining the connection weight of each WiFi hotspot, the terminal device can use the WiFi hotspot with the largest connection weight as the target WiFi hotspot, and then access the WiFi hotspot. Or, after acquiring the currently accessible WiFi hotspot list, the terminal device deletes the WiFi hotspots whose connection weight is less than the fifth threshold (for example, β<0.5) in the WiFi hotspot list, and displays the updated WiFi hotspot list for the user to use. choose.
