Description

Technical Field

[0001] The present invention relates to the field of network security technology, and specifically to a signaling parsing and wireless security control method. Background Art

[0002] The existing shielding technology is based on the principle of noise interference. The signal transmission frequency is in the same channel as mobile communication. It mainly increases a certain power amplification to transmit noise and block the normal communication of illegal users. With the gradual maturity and development of the anti-interference performance of broadband mobile communication technology, the noise interference mode requires a large power output to effectively shield and block communication signals.

[0003] If it is necessary to effectively interfere with the communication frequency points of all GSM, DCS, and FDD formats, it is necessary to superimpose a broadband signal greater than 32 times (15 dB - 18 dB) of the current signal within the communication frequency bands of all GSM, DCS, and FDD formats. A shielding device with a high power is required to emit a power output of 100 W - 300 W to effectively interfere with or shield and block communication.

[0004] If it is necessary to effectively interfere with broadband mobile communications such as CDMA / WCDMA / CDMA2000 / 4G TDD / 5G - SA / NSA, it is necessary to superimpose a broadband signal greater than 128 times or more (21 dB - 24 dB) of the current signal within the original frequency band. A shielding device is required to emit a power output of 800 W - 1000 W to effectively interfere. (For example Figure 1 )

[0005] Due to the gradual increase of high-frequency signals in the current wireless network and the gradual reclamation and broadening of the frequency band width, the transmitted power has also increased the signal strength of communication. The traditional low-cost noise interference mode can no longer meet the requirements of the shielding and control effect of current signals. Summary of the Invention

[0006] The purpose of the present invention is to provide a signaling parsing and wireless security control method to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A signaling parsing and wireless security control method includes the following steps:

[0009] Step 1, real-time tracking signaling monitoring of the operator's entire network signals;

[0010] Step 2, the signaling parsing system randomly generates blocking signals;

[0011] Step 3, transmit a re-modulated entire network signaling blocking signal;

[0012] Step 4: The terminal receives both the blocking signal and the operator signal simultaneously.

[0013] Step 5: The re-modulated signal is higher than the public network signal and disrupts the HDC.

[0014] Step 6: The terminals in the controlled area cannot communicate or have no network service.

[0015] As a further technical solution of the present invention: Through the signal acquisition device, comprehensive communication data of all frequency bands and multiple systems of the operator's communication signal is collected and analyzed, real-time tracking of the signaling of the operator's entire network signal is carried out, and the downlink channel frequency points of the current operator's base station work are accurately locked in real time.

[0016] As a further technical solution of the present invention: The signaling analysis system analyzes the collected communication data frames, and analyzes the Head Ctrl data frame of the Head data packet of the wireless signal communication data packet, and randomly reorganizes the frame data of the HDC frame control channel data.

[0017] As a further technical solution of the present invention: The data of the Head Ctrl data frame control channel is changed from the regular agreed protocol data to the irregular non-agreed data, so that the wireless signal mobile phone cannot effectively identify the received data frame / Head file packet.

[0018] As a further technical solution of the present invention: The operator's entire network signal includes data and voice communication services of different systems in the full frequency bands of 2G, 3G, 4G, and 5G.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The signaling analysis blocking signal shielding mode of this system works in the same frequency channel as mobile communication, can effectively analyze the HDC of the downlink data frame and reorganize it, and transmit it with a certain power to block the normal communication of illegal users. It has obvious advantages of low power and high efficiency. The data frame analysis only targets the downlink signal of the base station, and the data frame of the base station uplink channel is not processed. A traditional device requires an output power of 600W - 800W, and the signaling shielding only needs 8W - 10W to achieve the shielding and control purpose within the area.

[0021] 2. The low power will inevitably significantly reduce the cost of our equipment. The purpose of signal signaling shielding and signal blocking can be achieved without more high-frequency power amplifier modules.

[0022] 3. The low power and high efficiency directly reduce the control cost for the controlled area we need to monitor, effectively prevent or effectively guard against the risk of signal leakage caused by illegally carrying mobile phone terminals. At the same time, it also brings convenience in management and saves a part of the human management cost caused by illegal signal terminals.

[0023] 4. It can improve the accuracy of control. In the supervised area, signaling shielding can effectively target the current communication downlink channel of the operator's base station, conduct precise monitoring and real-time analysis and control, and cause the wireless signal communication terminal protocol handshake in the controlled area to fail to establish a communication connection.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1, as Figures 1-5 shown, the signaling parsing and wireless security control method includes the following steps:

[0031] Step 1: Real-time tracking signaling monitoring of the operator's entire network signal;

[0032] Step 2: The signaling parsing system randomly generates a blocking signal;

[0033] Step 3: Transmit a re-modulated entire network signaling blocking signal;

[0034] Step 4: The terminal receives the blocking signal and the operator signal simultaneously;

[0035] Step 5: The re-modulated signal is higher than the public network signal and destroys the HDC;

[0036] Step 6: The terminal in the controlled area cannot communicate or has no network service.

[0037] The signal acquisition device of this system comprehensively collects and analyzes communication data in the full frequency band and multiple systems of the operator's communication signals, monitors the real-time tracking signaling of the operator's entire network signals, and accurately locks the downlink channel frequency points of the current operator's base stations in real time. (Such as Figure 4 )

[0038] The signal analysis device of this system analyzes the collected communication data frames, and through signaling, analyzes the Head Ctrl (HDC) data frames of the Head data packets of the wireless signal communication data packets, and randomly reorganizes the frame data by analyzing the HDC frame control channel data. The HDC frame control channel data is changed from regular agreed protocol data to irregular non-agreed data, so that the wireless signal mobile phone cannot effectively identify the received data frames / Head file packets. This technology can be applied to the effective management and control of data and voice communication services in different systems of the full frequency band of 2G, 3G, 4G, and 5G at the same time. (Such as Figure 2 )

[0039] The system is designed with a mature distributed architecture. First, it effectively controls the boundary leakage risk of the shielding and blocking signals; second, it can prevent the wireless signal communication terminal from connecting to the base station through the data frames of signaling shielding. (Such as Figure 4 )

[0040] The system function mainly generates randomly encoded and reorganized data frames through the communication data collection and analysis device and the signaling shielding module in the control area, then amplifies the signals through the system control host unit, transmits them to the signal extension unit through wired transmission, and the signal extension unit emits them to different control area positions through passive or active antenna feeder systems, so that the mobile phone terminals in the control area cannot connect to the operator's base station, that is, when the mobile phone receives the downlink data from the base station, it causes a state where the connection between the 5G mobile phone terminal and the 5G communication base station fails. (Such as Figure 3 )

[0041] This design uses digital analysis signal signaling shielding technology, adopts the characteristics of low-power and high-efficiency signaling analysis algorithms, especially in the field of signal control, to enable communication devices for wireless security control to achieve the practical application of signaling shielding and scrambling to block communication, and effectively plays a good role in the wireless security control of signals.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

[0043] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
