Problems solved by technology

This jammer has high transmission power, severe frequency interference, large interference area, and long opening time, which can easily cause panic and alertness of the monitoring target, and even arouse public concern. The interference target is completely unclear, and the macro network is particularly affected.
In addition, experiments have been carried out on dozens of mobile phones that have been on the market. It often appears that monitoring mobile phones within a range of 1 to 3 meters cannot collect the required information.
[0003] Other methods, such as directly establishing 2G, 3G, 4G, 4G+, and 5G pseudo base stations within the monitoring range, are theoretically feasible, but there is no actual deployment and implementation, because 3G, 4G, 4G+, and even 5G signal make it more complicated, the cost of the whole system is extremely expensive
[0004] In addition, there are many frequency points like 4G LTE TDD, and there is no effective solution at present

Embodiment 1

[0030] see Figure 2 to Figure 4 As shown, the present invention is a system for obtaining mobile phone information in the monitoring area, including a device end, a terminal and a database, the device end includes a pseudo base station, a hub and a 5.8G GFSK transceiver module, and the pseudo base station includes a GSM pseudo base station and a 4G LTE pseudo base station. The terminal is a wireless terminal, and the hub is connected to the GSM pseudo base station, 4G LTE pseudo base station and 5.8G GFSK transceiver module respectively. The GSM pseudo base station and 4G LTE pseudo base station communicate with each other through the hub, and the GSM pseudo base station and 4G LTE pseudo base station respectively transmit and receive through 5.8G GFSK The module communicates wirelessly with the wireless terminal. The wireless terminal is equipped with an APP. The wireless terminal obtains the relevant information of the macro base station in the monitoring area, and performs ...

Embodiment 2

[0035] see Figure 5 to Figure 7 As shown, the number of LTE TDD mobile base station frequency points is large (as many as 7 have been tested and found), and office buildings and residential areas where a large number of people gather are particularly difficult to effectively capture the relevant information of target mobile phones in the monitoring area. One of the reasons for the low capture rate. Figure 5 It is the TDD frequency points scanned in a monitoring area, which are 37900, 38098, 38400, 39148, 38950, and 40540.

[0036] Therefore, this embodiment proposes a pseudo base station construction method, the core of which is to select a reasonable pseudo base station construction method based on the principle of base station attraction and interference, combined with the test results of the on-site macro network environment, and construct the pseudo base station according to requirements. This embodiment takes the construction of a 4G LTE TDD pseudo base station as an e...

Abstract

The invention discloses a method for constructing a systematic pseudo-base station, including S1: macro network environment scanning; S2: data comparison; S3: macro-net data processing; S4: pseudo base station construction. The present invention also includes a system for obtaining mobile phone information in the monitoring area, including a GSM pseudo base station, a 4G LTE pseudo base station, a hub, a transceiver module, a wireless terminal and a database, and the hub is respectively connected to the GSM pseudo base station, 4G LTE pseudo base station and the transceiver module. The GSM pseudo base station and the 4G LTE pseudo base station perform wireless communication through the transceiver module and the wireless terminal respectively. The wireless terminal is installed with an APP, and the wireless terminal obtains relevant information of the macro base station in the monitoring area, and performs data processing operations related to the database through the APP. The GSM pseudo base station and 4G LTE pseudo base station send instructions, and the GSM pseudo base station and 4G LTE pseudo base station obtain the information of the target mobile phone in the monitoring area and send it to the wireless terminal.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a system for obtaining mobile phone information in a monitoring area and a method for constructing a pseudo base station of the system. Background technique [0002] The system that captures the target mobile phone information in the monitoring area is widely used in special industries, such as prisons. It is usually based on GSM pseudo base stations and high-power full-band (including 3G and 4G frequency band) interference equipment. As far as the systems currently on the market are concerned, the system flow is roughly as follows: figure 1 As shown, the main use of full-band jammers is to suppress all mobile phones in the area and assign them to the frequency points of the pseudo-base stations built. This jammer has high transmission power, serious frequency interference, large interference area, and long activation time. It is easy to cause panic and alertness of the monit...
