Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a network positioning method according to an embodiment of the present invention, in which a MAC address of a target Wifi and a MAC of the target Wifi are recorded in the terminal device. The N signal strengths and the N geographic locations corresponding to the address, the N signal strengths are in one-to-one correspondence with the N geographic locations, and the N is a positive integer, and includes the following steps:

S101. The terminal device accesses the target Wifi.

S102. When the terminal device detects the network positioning instruction, the terminal device acquires a current signal strength that the terminal device currently receives the target Wifi.

S103. When the absolute value of the difference between the current signal strength and the target signal strength is less than or equal to a preset threshold, the terminal device uses the target geographic location as the current geographic location of the terminal device, where the target signal strength is The last time the terminal device accesses the target Wifi, the terminal device receives the signal strength of the target Wifi when the terminal device performs network positioning, and the target geographic location is the last time the terminal device accesses After the target Wifi, the terminal device performs network positioning to obtain the geographic location of the terminal device, the N signal strengths include the target signal strength, and the N geographic locations include the target geographic location.

It should be noted that the N signal strengths include at least the target signal strength, and the N geographic locations include at least the target geographic location.

The preset threshold may be, for example, 5 db, 10 db, 12 db, 15 db, 20 db, or other values.

Optionally, the network positioning instruction is that the terminal device triggers when detecting that the current interface includes a function that requires a geographic location.

The current interface may be a payment interface, an information reading interface, an APP home page, a status interface (such as a circle of friends), and the like.

For example, most functions of the APP now need to obtain the current geographic location of the user, for example, need to know the current geographic location of the user to recommend the resources closer to the user, such as recommending the food closer to the user, or uploading or Sending a circle of friends needs to get the user's current location, and so on. When the current interface of the terminal device includes a function that requires a geographic location, the terminal device directly triggers a network positioning instruction to perform network positioning.

Optionally, the network positioning instruction is triggered by the terminal device when detecting that the N is greater than or equal to a set value.

Wherein, the set value may be equal to, for example, 10 times, 11 times, 13 times, 15 times, 17 times, 20 times or Is another value.

Specifically, assuming that the set value is 15 times, N=20, the associated devices record the N geographic locations corresponding to the target Wifi, that is, the number of times the terminal device performs network positioning after accessing the target Wifi is at least 20 Times (greater than 15). It can be seen that, in the case that the terminal device accesses the target Wifi, the possibility of performing network positioning is large, and in order to further accelerate the speed at which the user obtains the geographical location, in this case, the terminal device directly starts the network positioning instruction.

For example, suppose the preset threshold is 10 db, the target Wifi MAC address is 123, the target signal strength is 100 db, and the target geographic location is A. After the current terminal device accesses the target Wifi, the user initiates network positioning, assuming the current terminal device. The current signal strength of the target Wifi is 107 db. It can be seen that the terminal device is connected to the same Wifi, and the signal strength of the terminal device connected to the Wifi is similar, and the user is considered not to move. At this time, the address A is directly used as the current geographical location of the terminal device. .

Optionally, if the N is an integer greater than 1, the method further includes:

When the absolute value of the difference between the current signal strength and the target signal strength is greater than the preset threshold, the terminal device selects W signal strengths from the N signal strengths, and from the N And selecting W geographic locations corresponding to the W signal strengths, where the W is an integer greater than 1; the terminal device according to the current signal strength, the W signal strengths and the W geographies Position, determining the current geographic location of the terminal device.

For example, if the target signal strength is 100 db, the current signal strength of the target Wifi received by the terminal device is 50 db, and the preset threshold is 10 db. It can be seen that the current signal strength of the target Wifi received by the terminal device differs greatly from the target signal strength. The user is considered to be mobile. In this case, the address A cannot be directly used as the current geographic location of the terminal device. The current geographic location of the terminal device needs to be re-confirmed. The specific manner of re-confirming the current geographic location of the terminal device is: selecting N from the N signal strengths. The signal strengths, and the W geographic locations corresponding to the W signal strengths are selected from the N geographic locations, and then determined based on the current signal strength, W signal strengths, and W geographic locations.

Optionally, the method further includes:

The terminal device records the current signal strength, the current geographic location of the terminal device, and the MAC address of the target Wifi.

Optionally, the terminal device further records N corresponding to the MAC address of the target Wifi. Recording time, the N recording times are in one-to-one correspondence with the N signal strengths, and the terminal device uses the target geographic location as the current geographic location of the terminal device, including:

When the target recording time is less than or equal to the preset time length, the terminal device uses the target geographic location as the current geographic location of the terminal device, and the target recording time is a record corresponding to the target signal strength. Recording time. That is to say, if the target recording time is shorter than the current time, the terminal device directly uses the geographical location obtained last time as the current geographic location of the terminal device.

The preset duration may be, for example, 1 day, 2 days, 3 days, 4 days, 8 days, 1 month, or other values.

Optionally, the method further includes:

When the target recording time is longer than the preset duration, the terminal device performs network positioning again to obtain the current geographic location of the terminal device.

The specific implementation manner of the terminal device re-sending the network to obtain the current geographic location of the terminal device may be: the terminal device starts the Wifi module to scan multiple hotspots around the terminal device to obtain multiple hotspot information (hotspot information such as hotspots) The MAC address, the terminal device receives the signal strength of the hotspot, and the like, and then the terminal device feeds back the obtained hotspot information to the server, and the server determines the current geographic location of the terminal device based on the multiple hotspot information fed back by the terminal device, and then the server determines The current location of the terminal device is fed back to the terminal device.

Optionally, the terminal device further records N access durations corresponding to the MAC address of the target Wifi, where the N access durations are in one-to-one correspondence with the N signal strengths, and the preset duration is Determined based on the access duration.

Optionally, the preset duration is equal to an access duration with a minimum duration of the N access durations; or the preset duration is equal to an access duration of a maximum duration of the N access durations; or The preset duration is equal to an average access duration of the N access durations.

For example, if N=5, the N access durations are: the first access duration is 10 min, the second access duration is 15 min, the third access duration is 20 min, and the fourth access duration is 12 min. The five access time is 25 minutes. Then the preset duration can be equal to 10 min, or 25 min, or 16.4 min.

It can be seen that determining the preset duration by the above manner can further determine the user's moving position. The possibility, in turn, further confirms the accuracy of the target geographic location as the current geographic location of the terminal device.

Compared with the prior art, the solution provided by the present invention records multiple signal strengths of the target Wifi and multiple geographical locations of the obtained terminal device when the terminal device performs positioning multiple times after the terminal device is connected to the target Wifi. The plurality of signal strengths include at least a target signal strength, and the plurality of geographic locations include at least a target geographic location, and the target signal strength is a target signal strength of the target Wifi received by the terminal device after the network positioning is performed after the last terminal device accesses the target Wifi. After the target location is the last time the terminal device accesses the target Wifi, the network location is obtained to obtain the target geographic location of the terminal device. When the terminal device performs network positioning after accessing the target Wifi, the current terminal device receives the current target Wifi. When the signal strength is not much different from the target signal strength, the target geographic location is directly used as the current geographic location of the terminal device, and the terminal device is not required to apply for network positioning to the server, and then the server performs positioning, and returns the positioning result to the terminal device, thereby shortening the positioning location. time needed.

The embodiment of the present invention further provides another more detailed method flow, where the terminal device records the MAC address of the target Wifi, and the N signal strengths, N geographic locations, and N records corresponding to the MAC address of the target Wifi.

If the absolute value of the difference between the current signal strength and the target signal strength is less than or equal to the preset The threshold is executed in step S205.

If the absolute value of the difference between the current signal strength and the target signal strength is greater than the preset threshold, steps S208-S210 are performed.

S205. The terminal device determines whether the target recording time is less than or equal to a preset duration, and the target recording time is a recording time corresponding to the target signal strength.
