When the signal of the mobile phone user is blocked by the pseudo base station, the mobile phone will send out a signal to automatically search the surrounding base stations. After the signaling monitoring system of the pseudo base station obtains the signal,

2. The pseudo base station can send short messages to the target users according to the obtained IMSI and other information. When the pseudo base station equipment is running, the signal of the user's mobile phone will be forcibly connected to the equipment within the effective range, which will cause the mobile phone to be unable to use the service provided by the operator normally in a short time.
