Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Although the 4G (the 4th Generation mobile communication technology, fourth Generation mobile communication technology) network is rapidly developed, many users exchange the previous SIM (Subscriber Identity Module) card with a USIM (Universal Subscriber Identity Module) card using a two-way authentication mechanism, however, the 2G (the 2nd Generation mobile communication technology) based network cannot be completely replaced in a short time, and a large number of terminals in the existing network support the users to roam freely in the 4G and 2G networks; and the second generation 2G cellular network does not perform integrity protection and only performs one-way authentication, and the Mobile terminal cannot identify whether the target wireless base station or the true base station is accessed, so that most of the current target wireless base stations imitate a 2G network, namely a Global System for Mobile Communication (GSM), use configuration resources such as System network numbers and frequency points of the existing Mobile network, and induce Mobile users to access through high-power signal transmission and extreme parameter configuration.
Specifically, in the working process of the current target wireless base station, firstly, a 4G signal jammer transmits a strong-power interference signal, so that a large-area 4G user cannot normally stay in a 4G network and fall back to a 2G network due to the fact that the 4G network has low signal quality; then, through high-power signal transmission, the mobile user in the suction area of the target wireless base station is sucked into a first 2G network cell provided by the target wireless base station, wherein when the embodiment is used for positioning the unauthorized wireless base station, the first 2G network cell can also be called an unauthorized 2G network cell, so that the unauthorized 2G network cell cannot normally communicate; mobile subscribers outside the suction area and within the interference area of the target radio base station fall back to the second 2G network cell, wherein, when the embodiment is used for positioning the unlicensed radio base station, the second 2G network cell can also be called a licensed 2G network cell, resulting in the data traffic being affected.
Based on the signal propagation characteristics of the target wireless base station, the present embodiment provides a model of the location-related area affected by the target wireless base station. Fig. 1 is a schematic model diagram of a location-related area according to an embodiment of the present disclosure. As shown in fig. 1, the model divides the peripheral area range of the target wireless base station into 3 concentric circles, namely, a target wireless base station signal suction area, a target wireless base station signal interference area and a position-related area from inside to outside based on the propagation characteristics of the mobile communication wireless signals, with the position point of the target wireless base station as the center. Wherein, the mobile user in the inhalation zone of the target wireless base station is inhaled into the unauthorized first network cell (such as unauthorized 2G network) provided by the target wireless base station, which results in the failure of normal communication; a mobile subscriber located outside the signal suction area and within the signal interference area of the target radio base station falls back to the authorized first network cell (e.g., the authorized 2G network used for normal mobile communication), causing its data traffic to be affected, and the location-related area covers the signal suction area and the signal interference area of the target radio base station. For example, according to the current signal propagation distance, the radius of the upper signal suction area is usually 200 to 300 meters, the radius of the target wireless base station signal interference area, i.e. the usable interference area, is 800 to 1000 meters, and the location association radius R of the location association area L Then a range larger than the radius of the signal interference area, i.e. larger than 1000 meters, is taken, for example, a value of 1500 meters.
Based on the model of the location-related area provided in this embodiment, the method for positioning a radio base station according to this embodiment will be described in detail with reference to the accompanying drawings. Fig. 2 is a flowchart illustrating a method for positioning a wireless base station according to an embodiment of the present invention. As shown in fig. 2, the method mainly includes the following steps:
s110: and respectively acquiring the number of first network resident users and the number of second network resident users at a first moment in the position association area of each grid in the target monitoring area, and the number of first network resident users and the number of second network resident users at a second moment.
First, the granularity of the geographical grid scanned within the target monitoring area is specified. Fig. 3 is a schematic diagram of a result of grid division in a target monitoring area according to an embodiment of the present application. As shown in fig. 3, the target monitoring area is divided into four grids, and it should be noted that this embodiment is only a schematic diagram, and may be divided into tens or even hundreds of grids in the specific implementation process. In order to ensure that all areas in each grid are analyzed, the present embodiment sets the coverage area of the location-related area corresponding to each grid to be larger than the area of the grid, and sets the radius of the location-related area (referred to as location-related radius R in the present embodiment) based on the characteristics that the higher the location accuracy of the radio base station and the smaller the granularity of the grid, the larger the analysis calculation amount, and the consideration of the location accuracy of the radio base station and the data processing amount L ) Is the radius R of the grid S It should be noted that, in this embodiment, the radius of the grid may be a distance from the center of the grid to any one of the sides of the grid, and if the distance from the center of the grid to each of the sides of the grid is different greatly, the radius may be an average value of the distances. For example, the grid grain size is set to 50 × 50 meters, or 100 × 100 meters. Then, the position association radius R is specified L . The location association radius R can be specified within the urban area for the interference range of the target radio base station of course L 1500 meters or 2000 meters, and then the radius R can be correlated with the center of the grid L The area covered by the radius is the location-related area.
Based on the above division result, the cells of the first network and the second network in each grid are obtained first, and specifically, the cells can be obtained from a cell engineering parameter table provided by a communication operator. In this embodiment, a network corresponding to a communication system adopted by the target wireless base station is a first network, for example, a 2G network is simulated, and a network in which a network accessed by a user that the target wireless base station can affect is out of the first network is referred to as a second network, for example, a 4G network, and certainly, the second network may also include a 3G network, even a 5G network, and the like. The method provided by the present embodiment will be described below by taking a 2G network and a 4G network as examples.

According to the above formulas (4) to (6), the longitude and latitude point p at the center of the grid k ＝(log k ,lat k ) In the location-related area, the number of the 2G resident users decreased at the second time is:
the number of the 4G resident users is reduced by the following steps:
correspondingly, the total number of the 2G and 4G resident users is reduced
And the second time is relative to the first time, and the inhalation rate of the target wireless base station in the position related area to the user is as follows:
s130: and judging whether a grid with a user inhalation rate larger than a preset inhalation rate threshold exists in each grid.
In practical wireless base station positioning systems, an inhalation threshold ρ is usually set according to the network scenario low When it is satisfied
ρ(t 0 →t 1 )＞ρ low Then, the longitude and latitude point p at the center of the current grid is explained k ＝(log k ,lat k ) If suspected target radio base stations are present near the location, step S140 is executed, and the next grid is shifted to perform the same user inhalation rate analysis until all grids are analyzed, it should be noted that, in a preset time, to achieve the efficiency of real-time positioning of the target radio base station, all grids are analyzed in one analysis period, for example, all grids in the target monitoring area are analyzed in one minute, otherwise, when ρ (t) is satisfied (t;) 0 →t 1 )≤ρ low Then, the longitude and latitude point p of the center of the current grid is described k ＝(log k ,lat k ) And the target wireless base station does not exist in the position, and the next grid is also switched to carry out the same user inhalation rate analysis until all grids are analyzed.
In addition, after all grids are analyzed, the next analysis period can be entered, and the same user inhalation rate analysis can be carried out on all grids in the target monitoring area so as to locate the target wireless base stations appearing in different grids at different moments.
S140: and if so, judging that the target wireless base station exists in the target monitoring area.
Based on the above steps, it can be seen that the concept based on the location-related user cluster and the method for analyzing the positioning of the wireless base station by combining the geographic grid, which are provided by this embodiment, construct a location-related area model for the inhalation characteristics of the location-related user cluster, perform full scanning according to the divided geographic grid, and screen the high-inhalation-rate regions, so that the reliability and accuracy of the identification result of the target wireless base station can be improved.

s150: comparing the user inhalation rates of the grids with the user inhalation rates larger than the preset inhalation rate threshold value to obtain the grid with the maximum user inhalation rate;
s160: and taking the geographical position of the grid with the maximum user inhalation rate as the position of the target wireless base station.
Based on the grid granularity set by the embodiment, the positioning accuracy of the target wireless base station is improved to be within 50 meters from the former 300-meter accurate positioning, and further, the efficiency of source management work of an unauthorized wireless base station can be greatly improved.
