The route setting processing operation shown in FIG. 4 is realized by the control unit 21 of the mobile phone 11 and the control unit 31 of the location information management server 15 each executing a control program stored in the memory.

  As described above, the parent who is the monitor connects the mobile phone 11 to the location information notification server 15 before passing the mobile phone 11 to the child who is the monitored person. For example, assuming a desired location such as home, school, school, friend's house, set the main points on the normal movement route connecting each location, such as the intersection to be passed, etc., and search the route data to make a mobile phone 11 is downloaded and stored. FIG. 4 shows the procedure at this time. If the monitored person can perform this operation, the monitored person may perform the operation.

  First, when a user (monitorer or monitored person) operates the operation unit 24 of the mobile phone 11 to input point information including a departure point and a destination point (step S401), the control unit 21 passes the wireless communication unit 23. To the location information management server 15 (step S402).

  When the process of step S402 is completed, the location information management server 15 receives the spot information from the mobile phone 11 via the transmission / reception unit 32 (step S403), accesses the map information database 34, and displays a map near the spot information. The data for reading is read (step S404), and the map display data read via the transmitting / receiving unit 32 is transmitted to the mobile phone 11 (step S405).

  When the process of step S405 is completed, the mobile phone 11 receives the map display data from the location information management server 15 via the wireless communication unit 23 (step S406) and displays it on the display unit 25 (step S407).

  Next, when the user operates the operation unit 24 of the mobile phone 11 to select a route candidate including a departure point and a destination point from the area of the map information displayed on the display unit 25 and inputs it as passing intersection information. (Step S408), the control part 21 transmits to the positional information management server 15 via the wireless communication part 23 (step S409).

  When the process of step S409 is completed, the location information management server 15 receives the passing intersection information from the mobile phone 11 via the transmission / reception unit 32 (step S410), and based on the map information stored in the map information database 34. The coordinate information on the route including the departure point and the destination point is calculated (step S411), the route coordinate information calculated via the transmission / reception unit 32 is transmitted to the mobile phone 11 (step S412), and the calculated route coordinate information is displayed.

  Next, the control unit 21 compares the detected coordinate information of the current position with the destination coordinate information stored in the memory 22 to determine whether or not the destination has been reached (step S503). If it is determined that it has arrived, the process ends.

  On the other hand, if the control unit 21 determines in step S503 that it has not arrived at the destination, it calculates the distance between the detected coordinate information of the current position and the route coordinate information stored in the memory 22 (step S503). In step S504, it is determined whether the detected current position is within a predetermined distance from the route (step S505). That is, it is determined whether the monitored person carrying the mobile phone 11 has escaped from the route assumed by the monitoring person in advance.

  When it is determined that the detected current position information is not within a predetermined distance from the route, the control unit 21 deviates from the route information and the detected coordinate information of the current position on the mobile phone 12 of the supervisor. When a mail is transmitted (step S506) and it is determined that the detected current position information is within a predetermined distance from the route, the process returns to step S501 and monitoring by the timer 27 is performed every predetermined time.

  Further, the control unit 21 constantly monitors whether or not a predetermined time has elapsed by the timer 27 (step S507), and detects the current position using the position detection unit 26 when the predetermined time has elapsed (step S508). The processing routine after step S507 monitors whether or not the monitored person's mobile phone 11 has returned to the route within a predetermined time after deviating from the route, and indicates that the monitor's mobile phone 12 has returned to the route. This is a notification process.

  That is, the control unit 21 calculates the distance between the detected coordinate information of the current position and the path coordinate information stored in the memory 22 (step S509), and whether or not the detected current position is within a predetermined distance from the path. (Step S510). That is, it is determined whether or not the monitored person carrying the mobile phone 11 has returned to the route predetermined by the monitoring person.

  If the control unit 21 determines that the current position information detected in step S510 is not within a predetermined distance from the route, the control unit 21 returns to step S506 to detect the coordinates of the current position detected on the monitor's mobile phone 12. Send an email stating that you have deviated from the information and route.

  On the other hand, if it is determined in step S510 that the current location information detected is within a predetermined distance from the route, the detected current location information and an email indicating that the route has been returned are transmitted to the mobile phone 12 of the supervisor. (Step S511), returning to the processing of Steps S501 and S502, the position measurement by the timer 27 is performed every predetermined time.

  By performing the processing as described above, when the monitored person's mobile phone deviates from the route, the monitoring person's mobile phone is automatically notified to that effect. It is no longer necessary to check the position of. Moreover, since it is possible to autonomously determine whether or not the route has been deviated by providing the route coordinate information on the mobile phone side of the monitored person, useless communication with the location information management server can be suppressed. Further, when the vehicle deviates from the route, it is possible to immediately notify the monitor. When the vehicle deviates from the route, the location information of the monitored person can be obtained by notifying the monitor of the location information every predetermined time. Since the history can be left on the monitor's mobile phone side, a highly reliable monitoring service can be provided.

  In the above-described embodiment, the mobile phone 11 detects the position of the mobile phone using the GPS function. However, the current location may be measured using the base station identification information in the cellular radio communication system.
