  Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG.

  FIG. 5 is a flowchart showing an outline of the operations of the earthquake information control unit 2, the base station 3, and the portable terminal 5. Steps S10 to S15 show the operation of the earthquake information control unit 2, and steps S20 to S25. Shows the operation of the base station 3, and steps S30 to S34 show the operation of the mobile terminal 5.

  In the following description, it is assumed that a telephone number of a notification destination terminal or the like is registered in advance in the safety confirmation telephone number section of the position information management data 61 included in the database of the position information management section 6. Further, it is assumed that the base station 3 holds location information (consisting of latitude information and longitude information) of the location where the base station 3 is installed in the storage unit 34. In addition, the user of the portable terminal 5 has previously registered in the storage unit 54 transmission permission / inhibition information indicating whether or not to permit transmission of the current position information measured by the position measurement unit 52 to the outside. To do.

  Referring to FIG. 5, first, when an earthquake occurs, the external organization 1 measures the seismic intensity at each location, publishes the measured seismic intensity at each location as seismic intensity information, and transmits the seismic intensity information to the earthquake information control unit 2. (Step S10), the earthquake information control unit 2 acquires the seismic intensity information (Step S11).

  Next, the information control part 2 at the time of an earthquake extracts the area | region where the seismic intensity more than predetermined value was measured from the acquired seismic intensity information, and shows the seismic intensity of the said area to all the base stations 3 installed in the said area Seismic intensity information is notified (step S12).

  Next, the interface unit 33 of each base station 3 receives the seismic intensity information notified from the earthquake information control unit 2 and sends it to the seismic intensity information acquisition / notification unit 30 (step S20).

  And the seismic intensity information acquisition / notification part 30 transmits the said seismic intensity information simultaneously with respect to all the portable terminals 5 which exist in the communication area which the self base station 3 takes charge (step S21).

  Next, when the control unit 51 of each mobile terminal 5 receives the seismic intensity information broadcast from the base station 3 (step S30), the current location information pre-registered in the storage unit 54 by the user is transmitted to the outside. Availability information is acquired (step S31).

  When the transmission permission / inhibition information is “No” (in the case of “NO” in Step S31), the control unit 51 ends the process.

  When the transmission permission information is “possible” (in the case of “YES” in step S31), the control unit 51 instructs the position measurement unit 52 to measure the current position of the mobile terminal 5, and the position measurement unit 52 Then, the current position indicated by longitude is measured (in the case of “YES” in step S32).

  And the control part 51 transmits the present position data containing the said present position information and the telephone number of the own portable terminal 5 to the base station 3 (step S33).

  Note that if the user is in a building or underground mall and the position measuring unit 52 cannot measure the current position (in the case of “NO” in step S32), the control unit 51 includes only the telephone number of the mobile terminal 5 itself. Current position data is transmitted to the base station 3 (step S34).

  The location information transmitting / receiving unit 31 of the base station 3 receives the current location data transmitted from each mobile terminal 5 (step S22), and checks whether there is current location information included in the current location data (step S23). .

  If the current position information exists (in the case of “YES” in step S23), it is left as it is. If the current position information does not exist (in the case of “NO” in step S23), the own base station held in the storage unit 34 New current position data is created by including the same value as the position information (consisting of latitude information and longitude information) of the installation location 3 as current position information in the current position data (step S24).

  Then, the position information transmission / reception unit 31 notifies the earthquake information control unit 2 of the current position data via the interface unit 33 (step S25).

  The earthquake information control unit 2 receives the current position data and passes it to the position information management unit 6 (step S13).

  Next, the location information management unit 6 searches for location information management data 61 having a location information transmission source telephone number portion in which a telephone number that matches the telephone number of the mobile terminal 5 included in the current location data is set. The contents of the current position data portion of the searched position information management data 61 are updated with the current position information (consisting of latitude information and longitude information) included in the current position data received in step S13 (step S14).

  Then, the location information management unit 6 indicates to the terminal having the telephone number indicated by the safety confirmation telephone number portion of the location information management data 61 updated in step S14 in the location information transmission source telephone number portion of the data 61. The telephone number and the latitude information and longitude information indicated in the current position data portion of the data 61 are notified (step S15).

  In the above description, it is determined whether or not the position of the portable terminal 5 can be transmitted in step S31, but the position of the portable terminal 5 is always transmitted without making such a determination. It is also possible to do so.

  In addition, when the position of the mobile terminal 5 cannot be measured in step S32, the location of the base station is used instead in step S24. Instead, the position of the mobile terminal 5 cannot be measured. Alternatively, only the telephone number of the portable terminal 5 may be notified to the terminal having the telephone number indicated by the safety confirmation telephone number portion of the location information management data 61.

  Further, the content of the current position data portion of the data 61 is updated in step S14, but the data 61 is received in step S13 without performing the update operation in step S14 without providing the current position data portion. The current position data may be notified to the corresponding terminal as it is in step S15.

  As described above, according to the present embodiment, when a large-scale earthquake occurs, the location information and the like are simultaneously transmitted from a large number of mobile terminals from a wide area, thereby causing congestion and location of the mobile phone communication network. There is an effect that it is possible to avoid problems such as failures due to the concentration of access to the database of the information management unit.

  The reason is that the information control unit at the time of earthquake selects only the area where the seismic intensity exceeding the predetermined value that is expected to be damaged is selected from the seismic intensity information obtained from external organizations, and is installed in that area. This is because the current position data is not transmitted from a mobile terminal other than the mobile terminal existing in the communication area in charge of each base station by notifying only the respective base stations of the seismic intensity information of the area.
