Here, step S121 includes: modifying the geographic location information in the stored field of the target wireless access point and modifying the neighboring wireless access points in the stored field of the target wireless access point. When a new target wireless access point is found, step S122 is performed, and the target wireless access point and its corresponding peripheral wireless access points need to be added to the database, so as to update the data storage of the target wireless access point in the database; if some target wireless access points may be expired and invalid in the stored data of the database, step S123 is performed, and if it is determined that the target wireless access points are expired, the expired target wireless access points need to be deleted from the database.
In this embodiment of the application, in step S121, the modifying the geographic location information in the stored field of the target wireless access point includes at least any one of the following: modifying, by one or more user devices, the geographic location information in the stored field of the target wireless access point when transmitting the geographic location information and received signal strength of the target wireless access point; modifying the geographical position information in the stored field of the target wireless access point according to the geographical position information and the received signal strength of a plurality of peripheral wireless access points corresponding to the target wireless access point; and modifying the geographical position information in the stored field of the target wireless access point through the geographical position information of the target wireless access point and the geographical position information of the corresponding peripheral wireless access points when one or more user equipment sends the target wireless access point.
Here, when the geographic location of the target wireless access point is updated, the target wireless access point may be located by the geographic location of the user equipment connected to the target wireless access point and/or the geographic location of the peripheral wireless access point corresponding to the user equipment, and a more accurate geographic location of the target wireless access point is obtained. When positioning a target wireless access point, for example, positioning may be performed according to the geographic location of one or more user equipments connected to the target wireless access point, and at this time, a course to an accurate update process may be performed, that is, positioning is performed multiple times, and accuracy is gradually performed; the target wireless access point can also be accurately positioned by using three user equipment connected with the target wireless access point directly by using a three-point positioning method.
Optionally, three user equipments may be selected to position the target wireless access point according to a three-point positioning method, and the specific implementation manner may be: determining any three user equipment having history sharing operation on the target wireless access point, and acquiring the geographical positions and the received signal strength of the three user equipment in the wireless access point topological network when the three user equipment have history sharing operation on the target wireless access point; and determining the actual geographic position of the target wireless access point according to the geographic positions and the received signal strengths of the three user equipment in the wireless access point topological network. Here, as shown in fig. 2, a schematic diagram of determining coordinates of a target wireless access point by using a three-point positioning method in a preferred embodiment of the present application is shown, where each wireless access point has received signal strength, and when the user equipment is at different distances from the wireless access point, the received signal strength is different, and the distance from the current user equipment to the wireless access point can be calculated, so that the coordinates of the target wireless access point in a wireless access point topology network diagram can be determined according to a three-point positioning rule and an actual coordinate position of each user equipment, and a specific process is as follows: determining any three user equipments, such as the user equipment A, B, C, having a history sharing operation on the target wireless access point a, and acquiring a geographical location and a received signal strength of the user equipment A, B, C having a history sharing operation on the target wireless access point a, wherein the geographical location is represented by longitude and latitude, such as the longitude and latitude of the user equipment a is (la1, lo1), the signal strength of the received target wireless access point a is rsi 1, the longitude and latitude of the user equipment B is (la2, lo2), the signal strength of the received target wireless access point a is rsi 2, the longitude and latitude of the user equipment a is (la3, lo3), the signal strength of the received target wireless access point a is rsi 3, the received signal strength is converted into a distance with the current longitude and latitude center of each user equipment as the center of a circle, and if the received signal strength is-70 dbm, the converted into a distance representing that the current user equipment is 300m away from the target wireless access point, the received signal strength is-20 dbm, the conversion into the distance represents that the distance between the current user equipment and the target wireless access point is 800m, the method for converting the received signal strength into the distance is only an example, circles are drawn by taking the converted distance as a radius to obtain three circles, and the longitude and latitude at the intersection of the three circles are taken as the coordinates of the target wireless access point a, so that the geographic position of the target wireless access point a can be more accurately positioned, and the geographic position stored in the field is modified.
Preferably, in step S121, modifying the peripheral wireless access points in the stored field of the target wireless access point includes: acquiring peripheral wireless access points corresponding to the target wireless access point, which are sent by the user equipment at different geographic positions; and obtaining a comparison result by comparing the received signal strength and/or the distance between the target wireless access point and each peripheral wireless access point, and modifying the peripheral wireless access points in the stored fields of the target wireless access point according to the comparison result. Here, when peripheral wireless access points of the target wireless access point are modified, several peripheral wireless access points closest to the target wireless access point may be determined by comparing the received signal strength of each peripheral wireless access point with the received signal strength of the target wireless access point, and several peripheral wireless access points closest to the target wireless access point may be obtained by using the geographical location information of the target wireless access point and each peripheral wireless access point, so as to update the peripheral wireless access points of the target wireless access point in the topology network. Of course, the received signal strength in combination with the geographical location information may also be used to update the surrounding wireless access points.
It should be noted that the association relationship of the peripheral wireless access points and the geographic position information of the peripheral wireless access points are stored, so that the geographic position of the target wireless access point can be updated more accurately; the more accurate position information of the target wireless access point can promote the position update of the peripheral wireless access points.
In one embodiment, when the user equipment connects to the target wireless access point a at a certain position a, the scanned peripheral wireless access points are a1, a2 and A3, and a1, a2 and A3 are stored in the field of the association data of the target wireless access point a, and when the user equipment connects to the target wireless access point a at another position b, the scanned peripheral wireless access points are a1, A3, a4 and a5, it is necessary to update the peripheral wireless access points previously stored in the field, including storing the peripheral wireless access points that have not appeared before, and also updating to compare the difference between the received signal strength of a1, a2 and A3 at position a and the received signal strength of the target wireless access point a, and simultaneously comparing the received signal strength of a4 and a5 at position b and the received signal strength of the target wireless access point a, and selecting the first few peripheral wireless access points with the smallest difference, for example, if a1, A3, and a4 are selected, the peripheral wireless access points already stored in the field are updated, and as a result, a1, A3, and a4 are stored in the field of the association data of the target wireless access point a.
Preferably, the method further comprises: step S01, setting a threshold of the storage number of the peripheral wireless access points corresponding to the target wireless access point in the field. Here, in order to reduce network overhead, a storage number threshold may be set when storing the peripheral wireless access points corresponding to the target wireless access point.
When the threshold of the storage number of the peripheral wireless access points is set, in step S121, a comparison result is obtained by comparing the received signal strength and/or the distance between the target wireless access point and each peripheral wireless access point; and modifying the peripheral wireless access points in the stored fields of the target wireless access point according to the comparison result and the storage quantity threshold value. For example, the threshold of the storage number of neighboring wireless access points is set to 3, the user equipment 1 detects that wireless access points B2, B3, B4, and B5 are around the target wireless access point B1, the received signal strengths are sequentially weakened, the received signal strengths of B1-B5 are respectively set to p1-p5, the distances between neighboring wireless access points corresponding to three received signal strengths having the closest received signal strengths to p1, that is, the minimum difference between the received signal strengths are the closest, and the neighboring wireless access points stored in the field before updating are performed using the three selected neighboring wireless access points having the minimum received signal strength difference. Of course, the stored peripheral wireless access points may also be updated using the difference between the geographic location of the target wireless access point and the geographic locations of the peripheral wireless access points.
In the embodiment of the present application, it is further noted that when the target wireless access point is stored to be used for generating the topology network, if the wireless access points of the same or similar identification information sent by multiple user equipment are simultaneously acquired, the target wireless access point is determined according to the determination rule. For example, if the sharing operation of multiple user equipment on the same or similar wireless access point names is acquired at the same time, the target wireless access point is determined according to the judgment rule. After a target wireless access point is determined according to the sharing operation of the user equipment and the information of the peripheral wireless access points of the target wireless access point is acquired, if the sharing operation of the plurality of user equipment on the same or similar wireless access point names is acquired at the same time, it is required to judge which wireless access point corresponding to the sharing operation of the user equipment is the target wireless access point.
In a specific embodiment, the determination rule includes at least any one of: if the wireless access points of the same or similar identification information sent by a plurality of user equipment are simultaneously obtained, the wireless access point sent by each user equipment is used as the target wireless access point; if the wireless access points of the same or similar identification information sent by a plurality of user equipment are simultaneously obtained, the wireless access point sent by each user equipment is not taken as the target wireless access point; and if the wireless access points of the same or similar identification information sent by the plurality of user equipment are acquired simultaneously, and the wireless access point sent by each user equipment is determined, selecting one wireless access point from the plurality of wireless access points as the target wireless access point. Optionally, selecting one wireless access point from a plurality of wireless access points as the target wireless access point may be implemented as follows: and determining the target wireless access point according to the received signal strength of each wireless access point.
The following implementations are also possible: and judging whether auxiliary wireless access points with the same or similar identification information exist among the plurality of wireless access points, and if so, determining the target wireless access point according to the received signal strength of the auxiliary wireless access points with the same or similar identification information corresponding to each wireless access point. For example, a target wireless access point a sent by multiple user equipment is acquired simultaneously, and an auxiliary wireless access point corresponding to the target wireless access point a sent by the first user equipment is a: -20db, secondary wireless access point b: -50 db; the auxiliary wireless access point corresponding to the target wireless access point a sent by the second user equipment is a: -30db, secondary wireless access point c: -60 db; it is determined which user equipment transmits the target wireless access point a to be reserved based on the received signal strength of the common auxiliary wireless access point a, for example, the target wireless access point a transmitted by the first user equipment is taken as the target wireless access point in the topological network, and its corresponding auxiliary wireless access points a and b are both reserved.
Preferably, in step S122, the newly acquired target wireless access point and the corresponding peripheral wireless access points thereof may be added to the database in a full data update manner according to a preset period. The method can also comprise the following steps: and storing the associated data corresponding to the newly acquired target wireless access point in an incremental data updating mode so as to add the newly acquired target wireless access point and the corresponding peripheral wireless access points to the database. When a new target wireless access point is found, the new target wireless access point and the corresponding peripheral wireless access points thereof need to be added into the topology network, and a full-volume updating mode and an incremental updating mode can be used, wherein the full-volume updating mode needs to set a period and periodically updates the topology network in the database; the incremental updating mode is not required to be regular, and when a new target wireless access point is found, a piece of data (comprising a plurality of fields) corresponding to the new target wireless access point is written into the database in an incremental mode to expand the topology network. However, after adding a newly acquired target wireless access point and its corresponding peripheral wireless access points to the topology network, the method includes: and modifying the geographical position information in the stored field of the newly acquired target wireless access point. Because the geographical location information of the target wireless access point may not be accurate when the information of the new target wireless access point is put into storage, it is also necessary to more accurately locate the new target wireless access point. When a new target wireless access point is located, the geographical position of the new target wireless access point may be located by using the geographical positions of the neighboring wireless access points of the new target wireless access point and/or the geographical position of the user equipment connected to the new target wireless access point.
Preferably, in step S123, it is determined whether at least one user equipment connected to a target wireless access point in the topology network exists when the time is greater than a preset time threshold, and if not, neighboring wireless access points corresponding to the target wireless access point are fed back to the user equipment; receiving association data corresponding to the wireless access points fed back when the user equipment is connected with each peripheral wireless access point, judging whether all the corresponding association data contain the target wireless access point, and if not, determining that the target wireless access point is an overdue target wireless access point; and deleting the expired target wireless access point.
Here, when there is a target wireless access point in the topology network and no user equipment is connected to use the target wireless access point within a time period exceeding a preset period, it needs to determine whether the target wireless access point is really an expired target wireless access point, and the determination method is as follows: firstly, user equipment is required to be used for connecting the target wireless access point, if no record of successful connection of the user equipment exists within a period of time, further judgment is required, the target wireless access point is searched by using the peripheral wireless access points of the target wireless access point, and if the target wireless access point is not searched when the user equipment is connected with the peripheral wireless access points, the target wireless access point is determined to be an overdue target wireless access point and needs to be deleted in the topological network.
The method provided by the application can be used for performing operations such as addition, modification and deletion on the topological network, so that the accuracy of the topological network graph is effectively improved, and the feasibility of the implementation of the topological network is ensured. For example, a more implementable topology network is used to make a risk determination for a wireless access point. The method comprises the following specific steps:

Here, the updated topological network diagram of the wireless access points is used to determine the risk of the wireless access points, and locate risky wireless access points such as emulational wireless access points and phishing wireless access points, in a specific embodiment, a user requests to obtain a connection password of the wireless access point B, a cloud obtains a connection request of the user of the wireless access point B, and simultaneously obtains peripheral wireless access points of the wireless access point B, and determines target wireless access point information and peripheral wireless access point information corresponding to the primary key information in the topological network according to the primary key information in the name of the wireless access point B, wherein the primary key information is generated by SSID and BSSID of the wireless access point, for example, the name of the wireless access point B is aabb, the primary key information is aabb, and the target wireless access point a corresponding to aabb is found in the topological network according to aabb, comparing the peripheral wireless access points of the wireless access point B with the peripheral wireless access points of the target wireless access point A, if the peripheral wireless access points are different, indicating that the wireless access point B is an isolated point in the topological network diagram and has a risk, further judging whether the risk exists or not, further judging according to the SSID, the BSSID, the base station information and the geographic position of the wireless access point B, and feeding back the final risk judgment result to the user.

Here, when peripheral wireless access points of the target wireless access point are modified, several peripheral wireless access points closest to the target wireless access point may be determined by comparing the received signal strength of each peripheral wireless access point with the received signal strength of the target wireless access point, and several peripheral wireless access points closest to the target wireless access point may be obtained by using the geographical location information of the target wireless access point and each peripheral wireless access point, so as to update the peripheral wireless access points of the target wireless access point in the topology network.

Of course, the stored peripheral wireless access points may also be updated using the difference between the geographic location of the target wireless access point and the geographic locations of the peripheral wireless access points.
In the embodiment of the present application, it is further noted that when the target wireless access point is stored to be used for generating the topology network, if the wireless access points of the same or similar identification information sent by multiple user equipment are simultaneously acquired, the target wireless access point is determined according to the determination rule. For example, if the sharing operation of multiple user equipment on the same or similar wireless access point names is acquired at the same time, the target wireless access point is determined according to the judgment rule. After a target wireless access point is determined according to the sharing operation of the user equipment and the information of the peripheral wireless access points of the target wireless access point is acquired, if the sharing operation of the plurality of user equipment on the same or similar wireless access point names is acquired at the same time, it is required to judge which wireless access point corresponding to the sharing operation of the user equipment is the target wireless access point. In a specific embodiment, the determination rule includes at least any one of: if the wireless access points of the same or similar identification information sent by a plurality of user equipment are simultaneously obtained, the wireless access point sent by each user equipment is used as the target wireless access point; if the wireless access points of the same or similar identification information sent by a plurality of user equipment are simultaneously obtained, the wireless access point sent by each user equipment is not taken as the target wireless access point; and if the wireless access points of the same or similar identification information sent by the plurality of user equipment are acquired simultaneously, and the wireless access point sent by each user equipment is determined, selecting one wireless access point from the plurality of wireless access points as the target wireless access point.
