Abstract
A mobile communication system includes a switching unit, a plurality of radio base stations, and a mobile station. The switching unit processes a call from an originating terminal. The radio base stations have service areas allowing radio communication and are connected to the switching unit. The mobile station performs radio communication with the radio base station within the service area. The switching unit includes a switching section, a database, and a message forming section. The switching section performs switching/connection between the originating terminal and the mobile station on a terminating side through the radio base station. The database stores last registration time recognized by the mobile station. The message forming section forms a speech message including the last registration time stored in the database and outputting the message to the originating terminal when there is no response from the mobile station with respect to a terminating operation.
