How can the base station accurately send short messages or call signals to my mobile phone instead of other people's mobile phones? My understanding is that the base station will transmit signals in all directions, but When your mobile phone is turned on, it will automatically send a notification to the surrounding base stations. After receiving it, the surrounding base stations will let you access the network and upload the location of the base station to the WAN, so that you can record which base station area you are in. If there is a phone call to you, I will find you from the recorded base station according to the recorded information, and the base station will find your terminal. That's all.
