A position detection system of a mobile terminal includes a small zone communication system (50) such as the PHS system, and a center station (1) connected to an exchange station (2) forming the PHS system. When a call is dispatched from the center station to the telephone number of a mobile station 7 of which the position is to be identified, the call signal is transmitted to a repeater (6) located closest to the mobile station (7) via exchange stations (2, 4) and main lines (3, 5) forming the PHS system (50). Since the mobile station (7) can identify the identification number of the closest repeater (6), the position of repeater (6) can be identified by referring to the database of the PHS system (50) using the repeater database provided in a center control station (51). The position can be displayed on a CRT screen at the center station (1) side. A position detection apparatus of a mobile terminal that can detect a position at low cost and at high accuracy is provided.
