Abstract The present invention relates to a mobile communication system. Particularly, the present invention provides a mobile communication system that has functions of autonomously relieving and recovering from a station-location-information loss phenomenon which may be caused when the system performs switching between active and standby home location registers in response to an occurrence of a fault. This mobile communication system has home location registers, visitor location registers, mobile switching centers, and mobile stations. In this mobile communication system, each of the home location register comprises a rerouting information acquisition section for performing routing information acquisition processing when receiving in response to a routing information acquisition message, which is sent out to one of the visitor location registers a response message indicating that a corresponding one of the mobile stations is not present.
