DISASTER PREVENTION RADIO COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To always quickly and accurately grasp the position of a slave station serving as a caller in a base station, when a call from the slave station is made, and consequently to deal with it quickly and appropriately. SOLUTION: When a telephone conversation button for an answerback call is operated in each field-type slave station FS1-FSn, a slave station monitoring response signal comprising a slave station's ID is generated, and is transmitted to a boss station BS. A console 1 of the base station BS receives a slave station monitoring response signal sent from each field-type station FS1-FSn, and extracts a slave station's ID from this signal. Along with reading out positional data of a corresponding slave station from a slave station management table 19a on the basis of this slave station's ID, the console 1 reads out map data comprising an installation position of the corresponding slave station from a map database 19b. On the basis of these read map data and positional data, the console 1 generates display data for displaying the installation position of the field-type slave station of the caller on a map, and displays these generated display data in its display section 18.
