Abstract
A stolen-vehicle monitoring system monitors a present position of a stolen-vehicle via radio communication between a monitor station and a vehicle-mounted device. When the vehicle-mounted device detects a vehicle theft, it automatically interrupts on-going communication between a car phone of the stolen-vehicle and an external phone if the car phone is being used for other than the monitor station and for low priority processing, and then dials to the monitor station to transmit present position information of the stolen-vehicle. When the monitor station calls the vehicle-mounted device, it interrupts on-going communication of the car phone and switches the communication to the monitor station to transmit the present position information to the monitor station.
