RADIO MOBILE COMMUNICATION SYSTEM

PURPOSE:To surely and speedily get contact with a mobile station from a caller by detecting the execution of position registration at the mobile station and retrieving whether the calling number of the mobile station is recorded or not. CONSTITUTION:When the caller registers a message on a mobile station 7, the caller registers the message on a recording means 3 connected to a mobile communication exchange 1 and disconnects a line. A position registration detecting means 4 judges whether there is the position registration from the mobile station 7 or not and when the position registration from the mobile station 7 is detected, a recorded information retrieving means 5 retrieves the message corresponding to the mobile station 7 by comparing the calling number of the mobile station 7, where the position registration is performed, with the calling number of a mobile station recorded in the recording means 3. When the recorded information retrieving means 5 detects the message, the mobile station 7 is called by a first call originating means 6a, and the message inside the recording means 3 is transmitted.
