Description

Signaling analysis and wireless security control method

Technical Field

The invention relates to the technical field of network security, in particular to a signaling analysis and wireless security control method.

Background

The existing shielding technology is a noise interference principle, and the signal transmitting frequency and the mobile communication are in the same channel, mainly by increasing certain power amplification to transmit noise, and normal communication of illegal users is blocked. With the gradual maturation and development of the anti-interference performance of the broadband mobile communication technology, a noise interference mode needs a large power output to realize effective shielding and blocking of communication signals.

If effective interference is to be formed on all communication frequency points of GSM, DCS, FDD, a wideband signal which is 32 times (15 dB-18 dB) larger than the current signal is required to be overlapped in the communication frequency band of GSM, DCS, FDD all modes, and high-power shielding equipment is required to transmit power at an output power of 100W-300W so as to effectively interfere or shield and block communication.

If effective interference is to be formed on wideband mobile communication such as CDMA/WCDMA/CDMA2000/4GTDD/5G-SA/NSA, wideband signals which are 128 times or more (21 dB-24 dB) than the current signals are required to be overlapped in the original frequency band, and the transmitting power of the shielding device is required to be 800W-1000W of output power to effectively interfere. (as in FIG. 1)

As the current wireless network high-frequency band signals are gradually increased, the frequency band width is gradually ploughed and widened, the transmitting power is also increased, and the signal intensity of communication is also increased, the traditional low-cost noise interference mode can not meet the shielding management and control effect requirement of the current signals.

Disclosure of Invention

The present invention is directed to a signaling parsing and wireless security control method, so as to solve the problems set forth in the background art.

In order to achieve the above purpose, the present invention provides the following technical solutions:

The signaling analysis and wireless safety control method comprises the following steps:

Step 1, monitoring an operator whole network signal in real time by tracking signaling;

step 2, the signaling analysis system randomly generates a blocking signal;

Step 3, transmitting a remodulated all-network signaling blocking signal;

step 4, the terminal receives the blocking signal and the operator signal at the same time;

step 5, the remodulated signal is higher than the public network signal and the HDC is destroyed;

And 6, the terminal in the management and control area cannot communicate or has no network service.

According to the invention, the signal acquisition device is used for acquiring and analyzing the full-frequency band and multi-system full-communication data of the communication signals of the operators, the full-network signals of the operators are monitored by tracking signaling in real time, and the frequency points of the downlink channels working on the base station of the current operators are accurately locked in real time.

The signaling analysis system analyzes the acquired communication data frame, analyzes the Head Ctrl data frame of the Head data packet of the wireless signal communication data packet through signaling, and randomly reorganizes the analysis frame data of the control channel data of the HDC frame.

As a further technical scheme of the invention, the Head Ctrl data 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 frame/Head file packet.

The invention further provides a technical scheme that the operator whole network signal comprises data and voice communication services of different modes of 2G, 3G, 4G and 5G whole frequency bands.

Compared with the prior art, the invention has the beneficial effects that:

1. The signaling analysis blocking signal shielding mode of the system works with the same frequency channel of the mobile communication, can effectively analyze the HDC of the downlink data frame and recombine the downlink data frame, transmits the downlink data frame with certain power to block the normal communication of illegal users, has the obvious advantages of low power and high efficiency, analyzes the data frame only aiming at the downlink signal of the base station, and does not process the data frame of the uplink channel of the base station. A traditional device needs 600W-800W of output power, and the signaling shielding can achieve the shielding control purpose within the area range only by 8W-10W.

2. The low power tends to obviously reduce the cost of the equipment, and the purpose of signal signaling shielding signal blocking can be realized without more high-frequency power amplifier modules.

3. The low power and high efficiency directly reduce the control cost for the control area which needs to be monitored, and effectively prevent or effectively prevent the risk of signal leakage caused by carrying the mobile phone terminal illegally. Meanwhile, the management is convenient and fast, and a part of labor management cost and the like caused by the illegal signal terminal are saved.

4. The control accuracy can be improved. In the monitoring area, the signaling shielding can effectively monitor and analyze and control the current communication downlink channel of the operator base station in real time, so that the communication connection establishment of the protocol handshake of the wireless signal communication terminal in the control area fails.
