People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, a mobile phone positioning system based on base station signals is limited to the implementation of the present invention by special state power organs such as national security, public security, confidentiality, and the military. It can detect and accurately locate 4G and 5G (SA) mobile communication terminal devices of operators such as China Mobile, China Unicom, and China Telecom in a specific area in real time, and specifically includes a background management module and the following connected to the background management module:

[0052] The virtual base station module is responsible for simulating the operator's mobile communication network broadcast induction signal and covering the target area so that the surrounding mobile terminals can detect the change of location area;

[0053] An intelligent frequency scanning configuration module, which is connected to the virtual base station module, and automatically scans and configures frequency parameters according to the surrounding base station environment, and transmits the frequency parameters to the virtual base station module for operation, so as to ensure that the intelligent frequency scanning configuration module can maintain compatibility with the surrounding mobile communication network;

[0054] A multi-frequency concurrent module, which is connected to the virtual base station module, captures signals at multiple frequencies simultaneously through the multi-frequency concurrent module, and transmits the captured signals to the virtual base station unit for processing;

[0055] The information collection module is used to receive the IMSI information reported by the mobile terminal, analyze and process the IMSI information, and then transmit it to the background management module in real time;

[0056] The information reported here includes not only the IMSI code, but also the location of the number, field strength value, total number of numbers, number of scans, etc.

[0057] The account management module is used to distinguish between the account information within the system and the account information outside the system, and to feed back the mobile phone signal corresponding to the account information outside the system to the background management module;

[0058] The positioning calculation module is used to locate the mobile phone corresponding to the signal of the account information outside the system and send the positioning information to the background management module.

[0059] Specifically, Figure 2 As shown, the virtual base station module includes:

[0060] The baseband board unit is responsible for processing the generation, analysis and transmission of virtual base station signals. It uses advanced digital signal processing technology to simulate base station signals consistent with the operator's network and achieve guidance and positioning of mobile terminals.

[0061] The transceiver RF unit is responsible for the transceiver work of the virtual base station signal. It receives the uplink signal of the mobile terminal through the antenna and transmits it to the baseband board unit for processing. At the same time, this unit is also responsible for sending the downlink signal generated by the baseband board module to the mobile terminal to complete the induction and positioning process;

[0062] The number of the above antennas is multiple to form an antenna array, which is used to realize directional transmission and reception of base station signals, specifically including GSM / DCS antenna, WCDMA antenna, 4G antenna, 5G antenna, which transmits and receives on China Mobile GSM, China Unicom GSM, China Unicom WCDMA, China Mobile TDD / FDD-LTE, China Unicom TDD / FDD-LTE, China Telecom TDD / FDD-LTE and other frequency bands. By adjusting the direction and gain of the antenna array, the positioning accuracy and coverage of the system can be further improved;

[0063] The power control unit is responsible for adjusting the transmission power of the virtual base station signal. The unit can automatically adjust the signal transmission power according to changes in the surrounding environment to ensure that the signal coverage and strength meet the positioning requirements.

[0064] Specifically, Figure 3 As shown, the multi-frequency concurrent module includes:

[0065] The multi-channel frequency point transceiver unit can quickly capture the target mobile phone through multi-channel simultaneous transmission of multiple frequencies, which greatly improves the detection efficiency and accuracy of the system. The virtual base station unit can induce and detect the access, registration and other signal transmission actions of the mobile terminal in real time by sending downlink signals and signaling, and extract relevant information from them.

[0066] The intelligent scheduling algorithm unit allocates resources through calculation scheduling to ensure that multiple frequency points work efficiently at the same time without interfering with each other.

[0067] The multi-frequency concurrent module adopts multi-frequency concurrent technology, which enables the system to capture the target mobile phone signal in a shorter time and improve the detection efficiency. Combined with the virtual base station technology, it can achieve high-precision positioning with an error of less than 0.2m.

[0068] Specifically, Figure 4 As shown, the intelligent frequency sweep configuration module includes:

[0069] The frequency scanner is responsible for automatically scanning the surrounding base station environment and obtaining the frequency usage in the current environment;

[0070] Through the frequency scanning function of the frequency scanner, the system can avoid frequency conflicts with the surrounding base station environment, thereby optimizing the signal reception and transmission effects, which helps to improve the stability and accuracy of the system and ensure that the mobile phone code detection and locating device can work efficiently and accurately;

[0071] Although the frequency sweeper itself does not directly implement the multi-frequency point concurrent function, it provides a basis for this function. Through the frequency information obtained by the frequency sweeper, the system can determine which frequencies are available, and accordingly assist the multi-frequency point concurrent module to realize the simultaneous signal capture of multiple frequencies.

[0072] The frequency scanner can also monitor the changes in the surrounding base station environment in real time and feed back the relevant information to the background management module, which enables the system to make adaptive adjustments according to environmental changes to ensure that it can maintain the best working state in different environments;

[0073] The signal processor is responsible for analyzing the spectrum of the surrounding base station environment;

[0074] The spectrum analysis algorithm unit automatically identifies and analyzes the frequency information of surrounding base stations based on the spectrum conditions, including frequency number and signal strength;

[0075] The intelligent configuration unit automatically configures the frequency parameters based on the collected frequency information, provides the virtual base station unit with the appropriate operating frequency and parameter settings, ensures that the virtual base station unit can maintain compatibility with the surrounding mobile communication network, and effectively induces the target mobile phone to connect to the signal, thereby optimizing the signal reception and transmission effects, so that the system can efficiently and accurately capture the target mobile phone signal;

[0076] When the intelligent configuration unit completes the frequency parameter configuration, the multi-frequency concurrent module will start working and simultaneously capture signals at multiple frequencies. These frequencies will cover all frequency bands that the target mobile phone may use, thereby ensuring that the system can fully and quickly capture the signal of the target mobile phone. Once the signal of the target mobile phone is captured, the multi-frequency concurrent module will immediately transmit the relevant information to the virtual base station unit for processing to achieve accurate positioning of the target mobile phone and subsequent operations.

[0077] Specifically, Figure 5 As shown, the information collection module includes:

[0078] The signal receiving unit is responsible for receiving the IMSI information reported by the mobile terminal and transmitting it in real time;

[0079] The information processing unit is responsible for parsing and storing the received IMSI information.

[0080] Specifically, Figure 6 As shown, the account management module includes:

[0081] A blacklist and whitelist preset unit distinguishes the account information in the system from the account information outside the system according to the mobile phone IMSI information by presetting the blacklist and whitelist;

[0082] The information comparison unit is responsible for storing the mobile phone IMSI information into the database for subsequent analysis, comparison and anomaly detection.

[0083] Specifically, Figure 7 As shown, the positioning calculation module includes:

[0084] The signal processing unit is responsible for preprocessing the mobile phone signals received from accounts outside the system to obtain characteristic information, such as signal strength measurement and propagation time calculation;

[0085] The positioning algorithm unit calculates the location of the mobile terminal through the acquired feature information.

[0086] Specifically, Figure 8 As shown, the background management module includes a processor and:

[0087] The database unit is responsible for storing the collected mobile terminal information, including IMSI, location information, etc.

[0088] The data analysis unit is responsible for analyzing and mining the collected information, such as collision analysis and accompanying analysis, so as to match and compare historical data and analyze the accompanying information of mobile phones;

[0089] Client software: The client software has a user interaction interface, is responsible for displaying mobile terminal information, and can also provide data query, permission login, map positioning and operation feedback;

[0090] This system can be used in conjunction with mobile phone electronic fences to accurately control specific areas or designated personnel.
