Mobile phone detection method.
Background technology
Existing mobile phone detection method mainly has two big classes, and the first concentrates on GSM or cdma system
Detection, makes the mobile phone terminal in coverage access by the way of building the pseudo-base station of GSM Yu CDMA
To pseudo-base station, thus the information such as the upward signal of mobile phone terminal even IMSI in obtaining region, reach to detect hands
The purpose of machine terminal is as right in patent " mobile terminal detection method based on software radio and detection system "
The detection of GSM Yu CDMA is made that associated description；The second is scanning cell phone by the way of spectrum scan
The uplink frame of terminal, there will be crest or burr when radio frequency receives the waveform of up frame signal time-frequency spectrometer,
Thus reach to detect the purpose of mobile phone terminal.
GSM with CDMA builds the method for pseudo-base station detection mobile phone signal and can only act as to 2G mobile phone terminal
With, the mobile phone terminal for WCDMA, TD-SCDMA, CDMA2000 and LTE is to detect,
Simultaneously because the loaded down with trivial details handling process of pseudo-base station, real-time also is difficult to reach satisfied effect, and this patent
Can detect the mobile phone terminal of 2G, 3G, 4G full system type pictorial, the mobile phone terminal of existing standard all will be by
Detect there is no the loaded down with trivial details processing procedure of pseudo-base station simultaneously, be only demodulated upward signal judging and joining
Closing the signal shielding of footprint edges, real-time is the highest；
For by the detection method of audiofrequency spectrometer, it is possible to the mobile phone terminal of business, idle shape are being initiated in detection
The terminal of state is difficult to detection, and signal and base station signal simultaneously for TDD standard mobile phone terminal are with frequency, frequency spectrum
Instrument cannot detect terminal signaling completely, and this patent is by synchronizing, and demodulation upward signal completes detection, accurate
Really property is high, there is not the problem that TDD standard cannot detect.
Summary of the invention
