Problems solved by technology

This method can accurately locate the base station, but it requires a lot of manpower and material resources, and requires high equipment, and it is impossible to know the approximate location of the pseudo base station in advance.
[0015] The disadvantage of the above-mentioned method 1 is that the response is slow and there are few positioning points; the disadvantage of the method 2 is that it can only describe the approximate location, and there is a problem of completeness; the disadvantage of the method 3 is that the cost of manpower and material resources is huge

Embodiment Construction

[0057] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] The present invention is realized by adopting the following technical scheme: the first step is coarse positioning of the coverage area of ​​the pseudo base station, and the second step is precise location discovery of the pseudo base station.

[0059] The invention provides a method for locating a pseudo base station, firstly performing rough positioning on the coverage area of ​​the pseudo base station, and then precisely locating the position of the pseudo base station. The method obtains the area where the false base station appears in real time, and can accurately locate the area.

[0060] Such as Figure 5 as shown, Figure 5 It is a flow chart of locating a pseudo base station in this embodiment, and the method includes the following steps:

[0061] Step 1, the signaling acquisition system acquires and filters the ...

Abstract

The invention provides a method for positioning a pseudo base station. The method comprises the following steps that (I) a signaling collection system acquires and filters location updating signaling of a user; (II) a location area of the pseudo base station is determined and is divided into location blocks; (III) a high-risk location block is determined; (IV) the pseudo base station is positioned by applying rayleigh distribution based on signal attenuation and a cooperative positioning technology based on an electromagnetic wave free space propagation model. According to the method, the area where the pseudo base station appears can be obtained in real time, and accurate positioning can be performed in the area; the problems that a traditional positioning method is slow in response and low in accuracy are solved, resources of law enforcement are saved, the pseudo base station can be effectively fought against, and normal network communication is protected.

Description

technical field [0001] The invention relates to a method in the field of signal identification and detection and information security, in particular to a method for locating a false base station. Background technique [0002] A "pseudo base station" is a false base station. The device is a high-tech instrument, generally composed of a host computer and a laptop computer. Through SMS group senders, SMS senders and other related equipment, it can search for mobile phone card information centered on it and within a certain radius. By disguising as an operator base station, arbitrarily fraudulently using other people's mobile phone numbers to forcibly send short messages such as fraud and advertising to the user's mobile phone. Some "pseudo base stations" are mobile, and criminal suspects usually place the "pseudo base station" equipment in the car, drive slowly or park the car in a specific area, and carry out text message fraud or advertising promotion. This makes it difficu...
