Title:
SIGNALING-TYPE MANAGEMENT AND CONTROL METHOD FOR MOBILE PHONE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2020/077955
Kind Code:
A1
Abstract:
Disclosed is a signaling-type method for a mobile phone signal, comprising: establishing a shielding processing system, and ensuring that the frequency reference of said system is synchronized with that of a base station; using the feature that a frame signal of a base station is repeatedly transmitted according to a frame period of the base station, receiving the frame signal of the base station at different times; performing filtering processing on the frame signals of the base station using a frame averaging method, so as to obtain purified frame reference signals of the base station; and using the purified frame reference signals to shield the base station. By means of the filtering processing performed on the frame signal using a frame averaging method, most of the modulated signals of user data are canceled by means of vector addition filtering due to the time-varying characteristics, while the reference signals from the base station to the mobile phone are enhanced because said signals are always present and have an unchanged phase. The purified frame reference signals of the base station are used for synchronous transmission, so as to disturb signals of the base station, so that the mobile phone cannot distinguish the signals, and when the interference is sufficiently strong, decoding fails and network connection is lost. The technology is effective for various mobile communications, and has high universality.
