Abstract: A signaling-type method for mobile phone signals, 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.

Abstract: The present invention provides a digital optical fiber-based distributed signal control system. The system mainly comprises a wireless signal access control module, a detection module, and a private network module. By means of reasonable frequency allocation and pre-selection filtering processing, modules can work together to implement control and detection of unauthorized mobile phone signals and guarantee communications of legal mobile phones, thereby achieving efficient coverage of a signal control area. A main control signal generated by a main control signal unit (SU) and an auxiliary control signal generated by a remote unit (RU) are mixed according to an algorithm, to achieve a better control effect in the entire signal control area.
