The method includes: locating a current geographic location; if the current geographic location belongs to a preset geographic location set, determining a currently connected Wi-Fi and the number of networks of the same frequency within the preset range; calculate the first weight corresponding to the signal strength of the currently connected Wi-Fi and calculate the number of networks of the same frequency within the preset range according to the preset method The corresponding second weight; if the sum of the first weight and the second weight is less than a preset threshold, try to connect to Wi-Fi of another frequency.

Please refer to FIG. 1. FIG. 1 is a method for network connection provided by an embodiment of the present invention. Wherein, as shown in FIG. 1 , a method for network connection provided by an embodiment of the present invention includes the following contents:

S101, locate the current geographic location;

Among them, it should be pointed out that the execution body of the method is the terminal. The terminals include, but are not limited to, electronic devices such as smart phones, tablet computers, computers, and wearable devices that can perform data transmission services through a network.

Wherein, the terminal can be positioned through a global positioning system (GPS), a Galileo positioning system or a Big Dipper positioning system.

The terminal may also perform positioning by interacting with the base station.

Wherein, it should be pointed out that before the current geographic location is located, the method further includes: prompting the user to set a geographic location set; receiving a keyword input by the user; searching for a geographic location matching the keyword; generating the preset geographic location set from the geographic location.

For example, a prompt can be sent to the user by means of voice, information or vibration, so that the user can set the geographic location set according to the prompt.

For example, if the user inputs a shopping mall, locate the itinerary area corresponding to the current user's location (such as a city, county or district, etc.) The preset geographic location set is generated.

S102. If the current geographic location belongs to a preset geographic location set, determine the signal strength of the currently connected Wi-Fi and the number of networks with the same frequency within a preset range;

For example, if the current location of the terminal is at an airport and the current geographic location belongs to a preset geographic location set, the terminal needs to determine the signal strength of the currently connected Wi-Fi and the number of networks with the same frequency within the preset range.

Among them, the current common frequencies of Wi-Fi are 2.4GHz and 5GHz, and 2.4GHz is more commonly used. Because 2.4G has good penetration and short transmission distance; while 5G has poor penetration and long transmission distance. In addition, the 2.4G frequency band has strong anti-attenuation ability in the indoor environment, but since many devices use 2.4GHz, there is a lot of interference, which cannot guarantee sufficient stability. The biggest advantage of the 5GHz frequency band is that there are few applications at present, so the interference is very small, and the quality of transmission can be guaranteed; but the disadvantage is also obvious, the indoor anti-attenuation ability is weak.

Specifically, the determining the signal strength of the currently connected Wi-Fi includes: acquiring the number of Wi-Fi signal bars displayed on the screen of the terminal; counting the uplink and downlink speeds of the network within a preset time; , the network uplink and downlink speed to calculate the signal strength.

Specifically, the determining the number of networks of the same frequency within a preset range includes: determining the coverage range of the currently connected Wi-Fi; determining a preset range according to the coverage range; scanning the network within the preset range Access Points; the properties of the scanned access points are analyzed to determine the number of networks on the same frequency.

S103. Calculate a first weight corresponding to the signal strength of the currently connected Wi-Fi in a preset manner and calculate a second weight corresponding to the number of networks with the same frequency within the preset range;

It should be pointed out that, for example, the weight of the signal strength is 50%, and the weight of the number of networks with the same frequency within the preset range is 50%. The distribution of weights is not restricted here.

For example, the total value of the weights is 100. The full number of signal strength grids is 5 grids, then one corresponds to 10; when the number of networks with the same frequency is 0-2, it corresponds to 50, when 2-4 corresponds to 40, and when 4-6 corresponds to 30, 6 -8 corresponds to 20, 8-10 corresponds to 10, and will not be listed one by one in the future.

S104. If the sum of the first weight and the second weight is less than a preset threshold, try to connect to Wi-Fi of another frequency.

For example, the current preset threshold is 60, if the current signal is 2 grids and the number of networks with the same frequency is 6, then the sum of the first weight and the second weight is 50, so it is less than the preset threshold 60.

If the currently connected network is a 2.4GHz network, then try to connect to a 5GHz network. If the currently connected network is a 5GHz network then try to connect to a 2.4GHz network.

Specifically, trying to connect to Wi-Fi of another frequency includes: starting the Wi-Fi scanning function to perform Wi-Fi scanning; reading the scanned Wi-Fi attribute to determine whether it is Wi-Fi of the other frequency ; When the scanned Wi-Fi is determined to be the Wi-Fi of the other frequency, try to obtain the scanned Wi-Fi password through the Internet; The password corresponding to Fi is used to connect to the network.

It can be seen that, in the solution of the embodiment of the present invention, the current geographic location is located; if the current geographic location belongs to the preset geographic location set, the signal strength of the currently connected Wi-Fi and the same frequency within the preset range are determined. The number of networks in the preset range; calculate the first weight corresponding to the signal strength of the currently connected Wi-Fi and calculate the second weight corresponding to the number of networks of the same frequency within the preset range according to the preset method; The sum of the first weight and the second weight is less than a preset threshold, and attempts to connect to Wi-Fi of another frequency. It can be seen that, by implementing the technical solution provided by the present invention, when the current location belongs to the preset location set and the current signal is poor, the network of another frequency can be automatically searched and accessed, so that there is no need for manual participation. , access to the network of another frequency with better signal.

Please refer to FIG. 2. FIG. 2 is a method for network connection provided by an embodiment of the present invention. Wherein, as shown in FIG. 2 , a method for network connection provided by an embodiment of the present invention includes the following contents:

S201, locate the current geographic location;

Among them, it should be pointed out that the execution body of the method is the terminal. The terminals include, but are not limited to, electronic devices such as smart phones, tablet computers, computers, and wearable devices that can perform data transmission services through a network.

Wherein, the terminal can be positioned through a global positioning system (GPS), a Galileo positioning system or a Big Dipper positioning system.

The terminal may also perform positioning by interacting with the base station.

Wherein, it should be pointed out that before the current geographic location is located, the method further includes: prompting the user to set a geographic location set; receiving a keyword input by the user; searching for a geographic location matching the keyword; generating the preset geographic location set from the geographic location.

For example, a prompt can be sent to the user by means of voice, information or vibration, so that the user can set the geographic location set according to the prompt.

For example, if the user inputs a shopping mall, locate the itinerary area corresponding to the current user's location (such as a city, county or district, etc.) The preset geographic location set is generated.

S202. If the current geographic location belongs to a preset geographic location set, acquire the number of Wi-Fi signal bars displayed on the screen of the terminal.

Among them, it is understandable that the wifi signal is displayed in an umbrella shape, and there are four states from weak to strong: none, 1 grid, 2 grid, and 3 grid.

S203. Statistics of the network uplink and downlink speeds within a preset time period.

Wherein, it can be understood that the preset time may be the default time of the terminal, or may be preset and stored by the user, wherein the preset time may be, for example, 5 minutes, 10 minutes, 15 minutes, 20 minutes wait or other length of time.

The network uplink speed refers to the speed at which the user uploads things through the network, such as the speed at which the user sends emails, uploads photos, and the like. The downlink speed only refers to the speed at which the user downloads things through the network, such as the speed at which the user watches movies and downloads things.

S204. Calculate the signal strength according to the signal grid number and the network uplink and downlink speeds.

It can be understood that if the number of signal grids is large and the network uplink and downlink speeds are fast, the signal strength is strong. On the contrary, if the signal grid number is small and the network uplink and downlink speeds are slow, the signal strength is weak. .

S205. Determine the coverage of the currently connected Wi-Fi.

Wherein, the coverage of the wifi is mainly determined by the wireless transmission power and the number of obstacles. According to the IEEE802.11 standard, the maximum distance that a general wireless router can cover is usually 100 meters to 300 meters, but the coverage range mainly depends on the openness of the environment, the number of buildings or other obstacles, and the degree of signal interference.

S206. Determine a preset range according to the coverage range.

Wherein, it can be understood that the preset range is less than or equal to the coverage range.

S207. Scan for access points within the preset range.

S208. Analyze the attributes of the scanned access points to determine the number of networks of the same frequency.

S209. Calculate a first weight corresponding to the signal strength of the currently connected Wi-Fi in a preset manner and calculate a second weight corresponding to the number of networks with the same frequency within the preset range.

It should be pointed out that, for example, the weight of the signal strength is 50%, and the weight of the number of networks with the same frequency within the preset range is 50%. The distribution of weights is not restricted here.

For example, the total value of the weights is 100. The full number of signal strength grids is 5 grids, then one corresponds to 10; when the number of networks with the same frequency is 0-2, it corresponds to 50, when 2-4 corresponds to 40, and when 4-6 corresponds to 30, 6 -8 corresponds to 20, 8-10 corresponds to 10, and will not be listed one by one in the future.

S210. If the sum of the first weight and the second weight is less than a preset threshold, try to connect to Wi-Fi of another frequency.

For example, the current preset threshold is 60, if the current signal is 2 grids and the number of networks with the same frequency is 6, then the sum of the first weight and the second weight is 50, so it is less than the preset threshold 60.

If the currently connected network is a 2.4GHz network, then try to connect to a 5GHz network. If the currently connected network is a 5GHz network then try to connect to a 2.4GHz network.

Specifically, trying to connect to Wi-Fi of another frequency includes: starting the Wi-Fi scanning function to perform Wi-Fi scanning; reading the scanned Wi-Fi attribute to determine whether it is Wi-Fi of the other frequency ; When the scanned Wi-Fi is determined to be the Wi-Fi of the other frequency, try to obtain the scanned Wi-Fi password through the Internet; The password corresponding to Fi is used to connect to the network.

It can be seen that the solution of the embodiment of the present invention extends the steps of determining the signal strength of the currently connected Wi-Fi and determining the number of networks of the same frequency within the preset range, so that the current location belongs to the preset location set and the current location When the signal is poor, it will automatically search for a network of another frequency and access it, so as to access the network of another frequency with a better signal without manual participation.

Please refer to FIG. 3 , which is a method for network connection provided by an embodiment of the present invention. Wherein, as shown in FIG. 3 , a method for network connection provided by an embodiment of the present invention includes the following contents:

S302. Receive a keyword input by a user.

S303. Search for a geographic location matching the keyword.

S305, locate the current geographic location.

S306. If the current geographic location belongs to a preset geographic location set, determine the signal strength of the currently connected Wi-Fi and the number of networks with the same frequency within a preset range.

S307. Calculate a first weight corresponding to the signal strength of the currently connected Wi-Fi and calculate a second weight corresponding to the number of networks with the same frequency within the preset range in a preset manner.

S308. If the sum of the first weight and the second weight is less than a preset threshold, enable a Wi-Fi scan function to perform Wi-Fi scan.
