LTE signal shielding method and system based on system information

The invention discloses an LTE signal shielding method and an LTE signal shielding system based on system information. The LTE signal shielding method specifically comprises the steps of: step (1) receiving LTE information of a working frequency point of an LTE base station in a target shielded region; step (2) acquiring physical layer identification information of an LTE cell under the working frequency point by utilizing the received LTE information; step (3) generating shielding signals according to the physical layer identification information of the LTE cell; step (4) and periodically transmitting the shielding signals. The LTE signal shielding method and the LTE signal shielding system can reduce interference on LTE base stations operating normally outside the target shielded region, effectively improve the LTE signal shielding efficiency of the shielding system, and reduce the realization difficulty and realization cost of LTE shielding signals. 本发明公开了种基于系统信息的LTE信号屏蔽方法和系统，方法具体包括：步骤(1)接收目标屏蔽区域内LTE基站工作频点
