Abstract

PURPOSE:To detect the movement position of a portable radio equipment automatically by a command signal from a base station. CONSTITUTION:In the service area Sa of a base station (a), radio stations b1-bn for position detection having serice areas Sb1-Sbn are arranged. The service areas Sb1-Sbn cover all the service area Sa of the base station (a). The base station (a) sends a command signal. On judging that the command signal is addressed to a portable radio station Cn, the station Cn lowers its transmission output below rated one and sets its transmission frequency to one for position detection to send a pilot signal for position detection at the transmission frequency. The radio station bm having received the signal transfers the details of it to the base station (a). The base station (a) discriminates the number of the radio station bm to detect the position of the portable radio station Cn. The portable radio station Cn has communication with the base station (a) with large output during call service.
