Abstract: Highly precise detection of occurrence of an abnormality in an out-of-service area is enabled. A server 5 includes an area identification unit 24A identifying an out-of-service area in which communication with an information communication device 3 is disabled, a determination unit 24B determining whether the information communication device 3 enters the out-of-service area or not by using the position information of the information communication device 3, a computation unit 24C calculating an expected stay time in which the information communication device 3 stays in the out-of-service area, and a notification control unit 24D executing notification processing for notifying predetermined information to a notification destination if it is determined that the information communication device 3 enters the out-of-service area and when an elapsed time from a time when communication with the information communication device 3 is disabled exceeds the expected stay time.
