Abstract
A method of determining a location of a mobile terminal location is provided. The method includes respectively receiving, by two antennas, first and second reception signals from the mobile terminal, calculating, by a communication module, a reception strength value (hereinafter referred to as RSSI_1) of the first reception signal and a reception strength value (hereinafter referred to as RSSI_2) of the second reception signal, and determining, by a location determination module, a region where the mobile terminal is located, based on a result obtained by comparing one RSSI of the RSSI_1 and the RSSI_2 with a reference value set based on a decision tree technique and a result obtained by comparing the one RSSI with a detailed reference value set based on a hysteresis technique.
