  Here, the operation of the subscriber management server 101 will be described with reference to FIG. The subscriber management server receives and stores mobile station location information from the base station apparatus regardless of whether or not emergency disaster information is received. When the emergency disaster information is received (step S601), information related to the disaster area included in the emergency disaster information is extracted (step S602). Then, based on the stored location information, the mobile device located in the disaster area is identified, the profile information of this mobile device (user) is extracted (step S603), and the extracted profile information is managed in the safety state management. It transmits to the server 102 (step S604).

Next, the subscriber management server 101 requests and receives the positioning information of the mobile station located in the disaster area from the base station apparatus (step S605), and transmits the received positioning information to the safety state management server 102. (Step S606).
As shown in FIG. 5, the subscriber management server 101 transfers the emergency disaster information to the safety state management server 102 by the operation shown in FIG. 6 (S2), and the profile of the user in the disaster area is managed in the safety state. It transmits to the server 102 (S3). Also, positioning information is received from the base station device (S4, S5) and transmitted to the safety state management server 102 (S6).

Moreover, the safety state management server 102 will start receiving positioning information directly from the base station apparatus 3a, if emergency disaster information is received (S7, S8). And a user's situation is judged based on positioning information, and the result of judgment is transmitted to map DB103 (S9). Map DB103 produces the map which shows the condition of the user in a disaster area using the transmitted determination result.
Here, the operation of the safety state management server 102 will be described with reference to FIG. When receiving the emergency disaster information (step S701), the safety state management server 102 starts a process of determining the user status (denoted as safety information in the figure) (step S702). Then, the profile information of the mobile device located in the disaster area is received (step S703), and the positioning information transmitted from the subscriber management server 101 is received (step S704).

Next, the safety state management server 102 receives the positioning information directly from the base station apparatus, detects the position of the mobile device (step S705), and compares this positioning information with the positioning information transmitted from the subscriber management server 101. To do. As a result of the comparison, it can be determined whether or not the mobile device has moved from just before the occurrence of the disaster to the present time (step S706).
If the mobile device is not moving as a result of the determination, there is a possibility that the user carrying the mobile device may be unable to move, so the safety state management server 102 may be affected by the user. (Step S707: Yes). Then, the positioning information transmitted from the subscriber management server 101 is added to the determination result “possible damage” (step S708), and is registered as a safety state (step S710).

  On the other hand, when it is determined in step S707 that the user is not damaged (step S707: No), the positioning information directly received from the base station device is added to the determination result “no possibility of damage” ( Step S709). The determination result to which the positioning information is added is registered as a safety state (step S710). Regardless of the result, the registered safety information is transmitted to the map DB 103 (step S711).

FIG. 8 is a diagram illustrating the safety information registered in step S710. In the illustrated example, the positioning information 801 before the disaster occurrence acquired by the safety state management server 102 from the subscriber management server 101 and the positioning information 802 directly received from the base station apparatus are indicated by coordinates. When the positioning information 802 is changed with respect to the positioning information 801, the changed positioning information 802 is added to the determination result of “no possibility of damage (denoted as damage: NO in the drawing)” and registered.
Registration is performed every predetermined time, and the previous determination result is updated by the subsequent determination result. For this reason, even if the positioning information 802 does not change immediately after the occurrence of the disaster as in the case of the user B shown in the figure, if there is a change with respect to the positioning information 801 after a plurality of updates, “no possibility of disaster” Determined.

(Example of determining the possibility of damage)
Note that the determination in step S707 of FIG. 7 described above is limited to the determination that “the possibility of disaster is immediately” when the mobile device is not moving, and “the possibility of damage is not immediately” when the mobile device is moving.

That is, when it is determined that the safety state determination unit 308 illustrated in FIG. 3 is not damaged by the user or may not be damaged, the moving speed, the moving time, and the movement time of the mobile device after the disaster occurrence time Based on at least one of the movement history, the stop time, and the stop position, it is possible to determine the possibility of the user's damage.

Hereinafter, the determination of the possibility of damage will be described with a specific example.
When the mobile device is moving: a When the moving speed of the mobile device is on the order of walking, it can be determined that the user is moving on foot. At this time, since it is considered that the user can move by himself / herself, the possibility that the user is not damaged is relatively high.
b When the moving speed of the mobile device is clearly faster than walking, if the movement history matches the route of public transportation, the user can estimate that the public transportation can be used. . For this reason, it can be determined that the possibility that the user is not damaged is relatively high.

When the mobile device is not moving c It is considered that the possibility that the user is damaged increases as the stop time of the mobile device becomes longer. In particular, when the stoppage time is more than one day, it is determined that the possibility of damage is high.
d When the stop position of the user is at home, the user may be at home, so the possibility that the user is damaged is considered to be relatively low. On the other hand, when the stop position of the user is a hospital or shelter, it is considered that the user is in a hospital or shelter, so that the possibility that the user is affected is relatively high.

The first embodiment is not limited to the configuration described above. That is, Embodiment 1 is not limited to the structure which detects the movement of a mobile device by a positioning apparatus. As another configuration for detecting movement, for example, switching of a base station apparatus communicating with a mobile device can be used. According to such a configuration, although the accuracy of detecting the movement of the mobile device is lowered, it can be applied to a mobile device that does not include a positioning device because it uses the location information.
Furthermore, as another configuration for detecting the movement of the mobile device, for example, an acceleration sensor or a pedometer (registered trademark) function provided in the mobile device can be considered. If the function of transmitting the output of the acceleration sensor and the output of the pedometer (registered trademark) function to the base station apparatus is added to the mobile station, it becomes possible to detect the movement of the mobile station.

When the emergency disaster information is received (step S1201), information related to the disaster area included in the emergency disaster information is extracted (step S1202). Then, based on the stored location information, the mobile device located in the disaster area is specified, the profile information of this mobile device (user) is extracted (step S1203), and the extracted profile information is managed in the safety state management. It transmits to the server (step S1204).

  Next, the subscriber management server requests and receives the positioning information of the mobile station located in the disaster area from the base station device (step S1205), and transmits the received positioning information to the safety state management server ( Step S1206). In addition, the subscriber management server 101 sequentially accumulates service usage information of mobile devices located in the disaster area, and creates a service usage history (step S1207). Then, the accumulated service use history is transmitted to the safety state management server (step S1208).

  Through the above operation, as shown in FIG. 11, the subscriber management server 101 transfers the emergency disaster information to the safety state management server 102 (S12), and the profile information of the users in the disaster area is transferred to the safety state management server 102. (S13). Further, positioning information is received from the base station device 3a (S14, 15), and transmitted to the safety state management server 102 (S16). Further, the service use history is transmitted to the safety state management server 102 (S17).

  In the second embodiment, as in the first embodiment, the safety state management server 102 starts receiving the positioning information from the base station device 3a by receiving emergency disaster information (S18, 19). The positioning information is used when the safety state is registered, as will be described later. The safety state management server 102 determines the status of the user based on the service usage history information, and transmits the determination result to the map DB 103 (S20). Map DB103 produces the map which shows the condition of the user in a disaster area using the transmitted determination result.

Here, the operation of the safety state management server will be described with reference to FIG. When the safety state management server receives the emergency disaster information (step S1301), the safety state management server starts a process of determining the user status (denoted as safety information in the figure) (step S1302). And the profile information of the mobile station located in a disaster area is received (step S1303).
Next, the safety state management server receives positioning information from the base station apparatus (step S1304). In addition, the service use history transmitted from the subscriber management server is received (step S1305). From the service usage history, it can be determined whether or not the mobile device has been operated after the occurrence of the disaster (step S1306).

  As a result of the determination, if the mobile device is not operated (step S1306: No), it can be estimated that the user carrying the mobile device is in an inoperable state. It is determined that there is a possibility of being (step S1307). Then, the positioning information transmitted from the base station apparatus is added to the determination result “possibility of disaster” (step S1308), and is registered as a safety state (step S1312).

  On the other hand, if it is determined in step S1306 that the mobile device is being operated (step S1307: Yes), the positioning information received from the base station apparatus is added to the determination result “no possibility of disaster” ( Step S1311). The determination result to which the positioning information is added is registered as a safety state (step S1312). Regardless of the result, the registered safety information is transmitted to the map DB 103 (step S1313).

(Judgment example of possibility of damage)
Note that the determination in step S1309 in FIG. 13 described above is not limited to the determination that “there is a possibility of disaster” immediately when the mobile device is operated. That is, even if it is determined that the user is not likely to be damaged, the safety state determination unit 308 shown in FIG. The magnitude of the possibility that the user is not damaged can be determined based on at least one of the contents of operations such as incoming and outgoing calls and network use.

Hereinafter, the determination of the possibility of damage will be described with a specific example.
a Even if the mobile device is being operated, it is considered that at least the user can operate the mobile device if the operation is intended to use mail or a network. For this reason, it is considered that the possibility that the user is not damaged is relatively high.
b On the other hand, if the operation of the mobile device is intended for a call, the user may be in a hurry to contact another person. For this reason, it is considered that the possibility that the user is not damaged is relatively low.
Note that the base station apparatus can detect that a user has placed a call by operating a mobile device even if, for example, communication is restricted due to communication congestion. For this reason, Embodiment 2 can determine a user's situation from the operation of the mobile device regardless of the communication state.

  The present invention can be applied to a system that determines a disaster situation for each predetermined area when a wide range of disasters occur. This is particularly effective when it is necessary to quickly determine the disaster situation in an area where it is difficult to enter from the viewpoint of road blocking and safety.
