Description
Technical Field
The invention relates to the technical field of radio monitoring, in particular to a pseudo base station detection system.
Background
The pseudo base station is a simulation base station which is not connected with a mobile communication network, and the mobile phone terminal is forcedly attracted to establish communication connection with the simulation base station through high-power transmission wireless signals, so that the simulation base station can be disguised as any calling number to send short messages with any quantity and any content to a user.
Such behavior belongs to the behavior of using a radio station by unauthorized setting, illegally occupying public spectrum resources, seriously damaging legal rights and interests of users and seriously disturbing normal public communication order. Meanwhile, the method has great threat to national security and social stability. The number of fraud messages sent by the pseudo base station in 2013 is up to one hundred billion. With the continuous improvement of the informatization level of China, the attack of a pseudo base station is increasingly vigorous, and great harm is brought to the social and economic development and information security of China. However, the "pseudo base station" has strong concealment and mobility, and the difficulty of finding or locating such illegal actions is high, so that the "pseudo base station" is hit as the key point of the current work for the radio management department.
The working principle of the pseudo base station is to establish a wireless network and establish an information channel with users in the covered area. The function of BSC, BTS, OMC, VLR is realized by adopting a single base station, a notebook terminal and a software platform, if a mobile phone of a user joins the network without knowledge, paging signaling information is received through the mobile phone, position registration information and corresponding IMSI, IMEI and other information are fed back, and after the pseudo base station obtains the information, the information is sent by utilizing the group sending soft part according to the number.
The pseudo base station is a user which is sucked into the covered area more, and the LAC value is set to be very different from the LAC value set by the base station running in the current network. And the discrimination of the pseudo base station is realized by judging through receiving the short message on the one hand, and on the other hand, the signal of the peripheral base station is searched by adopting a special instrument, the LAC value of the peripheral base station is obtained through signaling analysis, and the preliminary screening is carried out through comparing the LAC values.
In addition, the identification of the network management software is mainly that if frequent location update registration applications are sent in a non-regional handover large area, a large number of dropped calls and handover are frequently conducted in the sector, and a certain number of handover times are set as a threshold value, so that an alarm is triggered, and the number of sectors affected by the pseudo base station is primarily judged.
The main tools for positioning pseudo base stations at present are as follows: mobile network management detection software, PR100, pseudo base station searching equipment of applicant company, pseudo base station searching equipment of Oriental Botai company, and DZR-100 hidden portable spectrometer of applicant company. These devices can each efficiently find a pseudo base station.
For example, the publication number of the applicant applied to 2013, 9 and 11 is CN203618052U, the name of the radio monitoring device which can be hidden is "a radio monitoring device which can be hidden", for example, the publication number of the applicant applied to 2013, 5 and 31 is CN203313197U, the name of the portable radio monitoring integrated machine with a receiving terminal is "a radio monitoring integrated machine which can be used for effectively searching for a pseudo base station.
With the appearance of the pseudo base station searching equipment, the pseudo base station equipment also develops towards concealment, intellectualization and anti-reconnaissance. Along with the increase of the national investigation and treatment force, lawbreakers have strong anti-reconnaissance capability, and the lawbreakers aim at the defect of initial pseudo base stations to carry out targeted technical upgrading improvement.
The new pseudo base station equipment is developed towards low cost and intellectualization, does not have a packaged chassis, is in a form of assembly of parts, has rough working and low cost, and adopts low-power emission. Secondly, the development is towards the concealing direction: the illegal person installs the "pseudo base station" equipment in the interlayer of the automobile interior trim panel, and the monitoring personnel can determine the suspected vehicle through technical means, but the "pseudo base station" cannot be found from the appearance.
In order to cover users as many as possible, the pseudo base station is usually arranged near a densely populated area, such as a commercial square, an office building, a station, a traffic intersection and other busy focusing areas, and the areas have the common point that the crowd is dense, the pseudo base station is hidden in a trunk, a knapsack, an electric car tail box and other places by lawless persons, and when the pseudo base station is hidden in the crowd, people who pull the trunk or ride electric cars in the densely populated area, the existing pseudo base station searching equipment is difficult to accurately judge which object is hidden in the pseudo base station, and detection personnel cannot be fully opened for detection.
