The purpose of designing an automatic system to identify mobile network users is to control the entry and exit of users to a specific location. The main idea is to set up a fake pseudo-base transceiver station (BTS) between the mobile phone and the nearest BTS. The mobile phone regularly reports its location to the nearest BTS. The key task is to search for the signal sent to the pseudo-BTS and extract the international mobile subscriber identity (IMSI) information. The proposed system will be able to communicate up to 12-30 meters. In addition, the system does not require a near-field communication tag, because the information is decoded by the communication protocols of the mobile network. Therefore, even the simplest and most basic mobile phones are identified by the system. In this paper, in addition to presenting the main idea, the hardware and software structures of the system are also described.
