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 embodiments described in the following exemplary embodiments do not represent all embodiments 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.
Referring to fig. 1, a flow chart of a method for generating a travel track of a wireless base station according to an embodiment of the present invention is shown in fig. 1, where the method includes the following steps:
step S110: and obtaining a plurality of wireless base station positioning points in the monitoring area according to the network switching information of the mobile terminal user in the monitoring area.
Although high-speed Communication networks, such as 4G (the 4Generation Mobile Communication technology, fourth Generation Mobile Communication technology) have been developed at a rapid pace, 2G (the 2Generation Mobile Communication technology, second Generation Mobile Communication technology) networks, namely GSM (Global System for Mobile Communication) Mobile Communication networks, cannot be completely replaced in a short period of time, and thus, current Mobile Communication terminals, such as smart phones, generally support roaming between 2G networks and other networks.
In order to perform 4G network communication, many users of mobile communication terminals exchange SIM (Subscriber Identity Module) cards used in the 2G network with USIM (Universal Subscriber Identity Module) cards using a bidirectional authentication mechanism, however, when the USIM roams to the 2G network, the USIM still performs the unidirectional authentication mechanism of the 2G network, which brings the opportunity of user suction to the wireless base station.
Most wireless base stations use the system network number, frequency point and other configuration resources of the existing mobile network by imitating a GSM system, and induce the access of mobile communication terminals by a high-power transmission mode and extreme parameter configuration.
The wireless base station firstly transmits a strong power interference signal through the 4G signal interference device and then transmits a high power signal to form a wireless base station network. In the area near the wireless base station, because the high-power signal transmitted by the wireless base station is far stronger than the signal of the telecommunication base station, the mobile communication terminal using the 2G network can be hijacked to the wireless base station network, and the mobile communication terminal using the 4G network falls back to the 2G network from the 4G network under the interference of the high-power interference signal of the wireless base station and is hijacked to the wireless base station network; in a region far from the wireless base station, the mobile communication terminal using the 4G network falls back from the 4G network to the legitimate 2G network under the interference of the wireless base station, so that the data service is affected.
Based on the interference characteristics of the wireless base station to the mobile communication terminal, the embodiment of the application is configuredA wireless base station location correlation model is created, and referring to fig. 2, the model takes the wireless base station planning location as the center, and divides the peripheral area of the wireless base station planning location into three concentric circles of a suction area, an interference area and a location correlation area in sequence. The mobile communication terminal in the suction area is hijacked from the 4G network to the wireless base station network, the mobile communication terminal in the interference area falls back from the 4G network to the legal 2G network, and the position-related area covers the suction area and the interference area, namely, the mobile communication terminal in the position-related area is influenced by the wireless base station at the central position. In a normal case, a location association radius R of a location association area can be set in an urban area L Is 1500 m or 2000 m.
And setting a monitoring area, and if the monitoring area comprises the position association area, carrying out 4G-2G network switching on a mobile terminal user in the monitoring area under the interference of the wireless base station.
In the embodiment of the present application, the analyzing of the network switching information in the monitored area may include the following steps:
first, a plurality of grid regions are divided in a monitoring area. Referring to fig. 3, a schematic diagram of grid division is provided for the embodiment of the present application, as shown in fig. 3, a radius of a grid is denoted by Rs, and Rs may be set to 50 meters, so that a granularity of the grid is 100 × 100, and the smaller the Rs is set, the higher accuracy of subsequent calculation is, but the calculation amount may also increase. In the embodiment of the present application, the position-related radius R is set L 1500 meters, 15 times the side length of the grid. The center of each grid area is taken as a circle center, and the radius R is related to the position L For the radius, a circular position-related region is respectively divided.
Then, referring to steps 1-1 to 1-4, the following process is performed for each grid region:
1-1, counting 2G network resident users and 4G network resident users at the first moment.
And searching the 2G network cell and the 4G network cell in the position association area of each grid from the cell engineering parameter table, and extracting the users residing in the 2G network cell and the 4G network cell from the mobile communication network data.
Setting grid center longitude and latitude point p k ＝(log k ,lat k ) At the correlation radius R L In the location association area of

Respectively expressed as:
in the above formulas (1) and (2),

associating a cell for the jth 4G location. The number of 2G cells and 4G cells may be obtained from a cell engineering parameters table provided by the mobile communications operator.
Acquisition at a first time instant, i.e. t 0 Time, the user cluster residing in the 2G cell:
is obtained at t 0 Time, the user cluster residing in the 4G cell:
and 1-2, counting 2G network resident users and 4G network resident users at the second moment.
At a second instant, i.e. t 1 At this moment, the resident location associated user cluster in the 2G cell is:
is obtained at t 1 At this moment, the resident location associated user cluster in the 4G cell is:
1-3, calculating a first quantity difference value of 2G network resident users at the first time and the second time, and calculating a second quantity difference value of 4G network resident users at the first time and the second time.
The first number difference is calculated as:
(7) in the formula (I), the compound is shown in the specification,
to represent
The total number of (c).
The second number difference is calculated as:
(8) in the formula (I), the compound is shown in the specification,

The total number of (c).
And 1-4, obtaining the suction rate of the wireless base station according to the ratio of the total difference of the users (namely the sum of the first quantity difference and the second quantity difference) reduced at the second moment to the total number of users (namely the sum of the 2G network resident users and the 4G network resident users at the first moment).
The total difference of the users decreased at the second moment is:
the calculation formula of the inhalation rate is:
finally, the suction rate of the grid area is compared with a preset threshold value rho low By comparison, if ρ (t) 0 →t 1 )＞ρ low If yes, the grid area is judged to be a suspected wireless base station positioning point, otherwise, the grid area is judged to be a current grid center longitude and latitude point p k ＝(log k ,lat k ) There is no suspected wireless base station location. Further, selecting the grid area with the maximum suction rate, and if the suction rate of the grid area is greater than a preset threshold value rho low Then, the grid area is determined as the positioning point of the wireless base station.
The positioning method of the wireless base station can improve the identification accuracy of the unauthorized wireless base station, the positioning error is more than 300 meters compared with the traditional positioning method of the wireless base station, the positioning error can be reduced by improving the granularity of the grid, for example, when the granularity of the grid is 50 x 50, the positioning error can be within 50 meters, the accuracy of less than 50 percent of the traditional positioning of the wireless base station is improved to more than 99 percent, the scientific credibility of the identification of the wireless base station can be ensured, and powerful technical support is provided for the timely positioning and capturing of the wireless base station.
At a certain positioning period t i In time, there may be multiple p k ＝(log k ,lat k ) Wireless base station locations are determined, which may belong to the travel trajectories of different wireless base stations.
In this embodiment, t is i The first wireless base station moving track T in time l (t i ) Defined as a directed vector consisting of a time series of anchor points of a wireless base station:
(11) in the formula, P 1 l Is the first trace point of the first wireless base station,
is the second track point of the first wireless base station, and so on, P i l Is the ith trace point of the first radio base station, and M is the time from the first trace point to t i The total number of the first wireless base stations in the time.
Two adjacent positioning periods, e.g. t i ,t j Two radio base station positioning points P adjacent to each other i And P j Judging whether to fit the wireless base station into a traveling track of the wireless base station through a certain time and position association algorithm, if P is i And P j Can be fitted to a wireless base station travel track T l The two wireless base station locations are referred to as two adjacent locations of the track.
In this embodiment, the algorithm for determining whether two anchor points are adjacent anchor points refers to steps S120 to S150:
step S120: a first wireless base station positioning point in a previous time period, which is different from the position of the wireless base station positioning point in the previous time period, in the first time period is obtained.
The length of one time interval can be selected to be 1 minute, the wireless base station positioning point is obtained every other minute, and after the wireless base station positioning point within 1 minute of the first time interval is obtained, because the travel track needs to be generated by track points with different positions, only the wireless base station positioning point with the changed position needs to be judged whether to be a new track point. In this step, the wireless base station location point whose position is different from the last minute is selected from the wireless base station location points obtained in the first time period and is marked as the first wireless base station location point.
Step S130: and judging whether a second wireless base station positioning point exists in the wireless base station positioning point in a preset time period before the first time period, wherein the distance between the second wireless base station positioning point and the first wireless base station positioning point is within a preset time-space association threshold range.
The first wireless base station positioning point may be a new track point of a previous wireless base station positioning point, or may be an initial track point of a new track, and the step determines the first wireless base station positioning point, referring to fig. 4, which is a schematic flow diagram of a track point determining method provided in the embodiment of the present application, as shown in fig. 4, the method includes steps S301 to S303:
step S301: judging whether a first adjacent positioning point exists in the last period of the first period, wherein the distance between the first adjacent positioning point and the positioning point of the first wireless base station is within a first time-space correlation threshold range;
and judging whether a first adjacent positioning point exists in the last minute of the first time interval. According to the traveling speed characteristics of the wireless base station, the first time-space correlation threshold range D is set according to the embodiment of the application th1 If a radio base station anchor point with a distance less than 600 meters from the first radio base station anchor point exists in the last minute, the radio base station anchor point with a distance less than 600 meters from the first radio base station anchor point is marked as a first adjacent anchor point, and the formula is as follows:
T l (t j )＝[T l (t i ),P j ],P i ∈T l ,D i,j ≤D th1 (12)
in the above formula, P i Indicating the location of the ith radio base station, P j Indicates the jth radio base station anchor point, T l Indicates the first wireless base station's travel track, T l (t j ) Represents T l By t j Track of time period, D i,j Represents P i And P j Distance between, T l (t i ) Represents T l By t i Track of time period, T l (t i ) And T l (t j ) All are directed vectors:
in the above formula, P 1 l Represents T l The first point of the trace of (a),
represents T l And so on for the first trace point.
Step S302: if the first adjacent positioning point does not exist, judging whether a second adjacent positioning point exists in a second time period before the first time period or not, wherein the distance between the second adjacent positioning point and the first wireless base station positioning point is within a second space-time correlation threshold range;
if the first adjacent positioning point does not exist in the last minute of the first time interval, the first time interval is pushed forward for one minute, and whether a second adjacent positioning point exists or not is judged in the second time interval. The second time period is selected to be 2 minutes before the first time period. Setting a second spatiotemporal association threshold D th2 When the maximum distance within two minutes of the wireless base station is 1200 m, if there exists a wireless base station positioning point within two minutes, which is less than 1200 m away from the first wireless base station positioning point, the wireless base station positioning point within 1200 m away from the first wireless base station positioning point is marked as the second adjacent positioning point, which is expressed by the following formula:
T l (t j )＝[T l (t i ),P j ],P i ∈T l ,D i,j ≤D th2 (14)
step S303: if the second adjacent positioning point does not exist, judging whether a third adjacent positioning point exists in a third time period before the first time period, wherein the distance between the third adjacent positioning point and the first wireless base station positioning point is within a third space-time correlation threshold range;
and if the second adjacent positioning point does not exist in the second time period, judging whether a third adjacent positioning point exists or not in the third time period. The third period of time is selected to be 3 minutes or 60 minutes before the first period of time. Setting a third null-association threshold D th3 If a radio base station anchor point with a distance to the first radio base station anchor point of less than 1500 m exists within three minutes or 60 minutes, then the radio base station anchor point with a distance to the first radio base station anchor point of less than 1500 m is marked as a third adjacent anchor point, and the formula is expressed as follows:
T l (t j )＝[T l (t i ),P j ],P i ∈T l ,D i,j ≤D th3 (15)
and the third time interval, the second time interval and the last time interval of the first time interval all belong to preset time intervals, the third time-space correlation threshold range, the second time-space correlation threshold range and the first time-space correlation threshold range all belong to preset time-space correlation threshold ranges, and the first adjacent positioning point, the second adjacent positioning point and the third adjacent positioning point all belong to a second wireless base station positioning point. Starting from step S301, if a first adjacent anchor point corresponding to a first spatio-temporal association threshold range exists in a previous period of a first period, go to step S140, if the first adjacent anchor point does not exist, continue to perform step S302, if a second adjacent anchor point corresponding to a second spatio-temporal association threshold range exists in a second period, go to step S140, if the second adjacent anchor point does not exist, continue to perform step S303, if a third adjacent anchor point corresponding to a third spatio-temporal association threshold range exists in a third period, go to step S140, and if the third adjacent anchor point does not exist, go to step S150.
Step S140: and if the second wireless base station positioning point exists, determining the first wireless base station positioning point as the next track point of the second wireless base station positioning point.
If there is a second wireless base station location point in any of steps S301-S303, the first wireless base station location point is determined as the next track point of the second wireless base station location point, i.e. the first wireless base station location point and the second wireless base station location point are adjacent location points.
