1. Overview

In the present embodiment, the state of the mobile terminal user is determined by a safety confirmation system using a function built in the mobile terminal. For example, when an earthquake occurs, a safety confirmation application is activated on the mobile terminal in response to the reception of the earthquake early warning transmitted from the center device to the mobile terminal. Next, the center device transmits a safety confirmation request to the portable terminal. If the user of the portable terminal is not in an emergency state, an input operation for a safety confirmation request can be performed from the input unit. Whether or not the user of the portable terminal is in an emergency state based on the presence or absence of a response to the sensor or the input unit for a portable terminal that does not respond to the safety confirmation request until the predetermined time has elapsed Determine whether or not. Specifically, the presence or absence of movement of the mobile terminal is determined by combining an acceleration sensor, a gyro sensor, or both sensors built in the mobile terminal. If the movement of the mobile terminal cannot be confirmed by the sensor within a predetermined time, for example, it can be considered that the mobile terminal user is likely not to have the mobile terminal. If the movement of the mobile terminal can be confirmed by the sensor before the predetermined time elapses, it is determined whether or not there is a response to the input unit such as the screen or button of the mobile terminal. If there is no response to the input unit before the predetermined time elapses, for example, it can be considered that there is a high possibility that the mobile terminal user cannot operate the mobile terminal. When there is no response to the safety confirmation request and the movement of the mobile terminal can be confirmed and there is a response to the input unit, for example, the mobile terminal user is in an emergency state where early relief is desirable (for example, movement It can be determined that there is a possibility that the fingertips are barely movable, but cannot be removed. The determination using the sensor and the input unit is repeated a predetermined number of times to determine the state of the mobile terminal and the mobile terminal user. After the state determination, the mobile terminal acquires position information using the GPS function, and the mobile terminal automatically transmits the determination content and the position information to the center device.

  The center device manages information on mobile terminals and mobile terminal users transmitted from the respective mobile terminals, and emergency information and / or rescue organizations registered in advance by the rescue team or mobile terminal users. To notify. The center device retransmits the safety confirmation request to the mobile terminal after a predetermined time has elapsed.

4). Flowcharts and tables

Operations of the portable terminals 100a and 100b and the center device 120 configured as described above will be described. Here, the characteristic operation of the present embodiment, that is, the operation of the mobile terminals 100a and 100b and the center apparatus 120 when receiving disaster information, which is located in the disaster area, will be mainly described.

  The flowchart of FIG. 6 shows the operation of the mobile terminals 100a and 100b when a disaster occurs, for example, when an earthquake occurs. First, when the mobile terminal 100a, b receives the earthquake early warning transmitted from the center device 120 in the flow 601, the safety confirmation application unit 214 starts the safety confirmation application in response to the reception of the emergency earthquake early warning in the flow 602. to start. Since such a method for remotely starting a mobile terminal application is already known, detailed description thereof is omitted here.

  In the flow 603, when the safety confirmation application unit 214 determines that the safety confirmation request transmitted from the center device 120 has been received (Yes in the flow 603), in the flow 604, the input of the safety state message from the mobile terminal user. Request reception. On the other hand, in the flow 603, when the safety confirmation application unit 214 cannot confirm the reception of the safety confirmation request transmitted from the center device 120 (No in the flow 603), the mobile terminals 100a and 100b end the processing.

  The content of the safety confirmation request in flow 604 and / or the content of the safety status message in flow 604 includes information related to the mobile terminal user, such as the current status of the mobile terminal user. The portable terminals 100a and 100b display a safety confirmation request input screen and input a safety status message or the like. The input screen may be transmitted from the center device 120, for example, or may be set in advance by a safety confirmation application of the mobile terminal. As the safety state message, for example, an appropriate format such as a sentence / word format such as an email or chat, an input item selection format, and an input format for an input form can be used. For example, there are multiple confirmation items such as safety information such as safety status and emergency status, date and time information, location information, etc. as input contents of the safety status message, and input methods such as selection and description are arbitrarily set for each item be able to. In addition, when there is an unselected item or an unfilled item in the input of the safety status message, the safety confirmation application unit 214 may prompt the input again. When no improvement is observed within a predetermined reception time, the safety confirmation application unit 214 assumes that the safety status message is not input, and performs the same operation as No in the flow 604 described later. be able to.

  In flow 604, when the mobile terminal user inputs a safety status message within a predetermined reception time (Yes in flow 604), in flow 605, the safety confirmation application unit 214 uses the GPS reception unit 202 to locate The current position information obtained by the information acquisition unit 212 is acquired. In flow 606, the safety confirmation application unit 214 includes the position information and the terminal information in the safety determination information, and transmits the information to the center device 120 by the safety determination processing unit 215 according to the transmission operation of the mobile terminal user. Here, the safety determination information transmitted in the flow 606 includes, for example, terminal information such as a terminal ID and user information, position information of latitude and longitude, safety confirmation response (with response), sensor information, input operation information, and position information positioning time. , Including a safety status message.

  On the other hand, when the mobile terminal user does not input the safety status message within the predetermined reception time (No in flow 604), the safety confirmation application unit 214 detects the sensor 235 built in the mobile terminals 100a and 100b. It is used to determine the status of the mobile terminals 100a and 100b and the mobile terminal user. First, in flow 607, the safety confirmation application unit 214 activates a sensor 235 that can detect the movement and inclination of the mobile terminals 100a and 100b, such as sensors built in the mobile terminals 100a and 100b, for example, an acceleration sensor and a gyro sensor. In the flow 608, the safety confirmation application unit 214 counts 1 for the number of sensor responses “present” when the movement of the mobile terminals 100a and 100b can be confirmed within a predetermined time using the sensor 235 (Yes in the flow 608). In step 609, the determination process using the input operation unit 231 is started. In the flow 610, the safety confirmation application unit 214 confirms the input operation to the input operation unit 231, for example, an input interface such as a touch panel, a cross key, and a number key within a predetermined time (Yes in the flow 610). 1 is counted as the number of times the operation section reaction is “present” (in this case, for example, it can be determined that the mobile user is highly likely to be in an emergency). In flow 611, the safety confirmation application unit 214 acquires the current location information from the location information acquisition unit 212. In flow 612, the safety determination information includes the location information and the terminal information, and the safety determination of the mobile terminals 100a and 100b. The processing unit 215 automatically transmits to the center device 120 via the transmission / reception unit 201.

  In the flow 610, unlike the flow 604, the input method and the input content are not limited, and it is only necessary to confirm the input operation to the input operation unit 231. For example, only an operation in which a finger touches the screen may be used. On the other hand, when the movement of the mobile terminals 100a and 100b cannot be confirmed within a predetermined time, the safety confirmation application unit 214 counts 1 for the sensor response “No” (No in the flow 608), and performs an input operation. When the input operation to the unit 231 cannot be confirmed, the input operation unit reaction “no” is counted by 1 (No in the flow 610), and the flow proceeds to the flow 613. In flow 613, the safety confirmation application unit 214 increments the state determination processing count n by 1. When the state determination processing count n exceeds the predetermined processing count N in flow 614 (Yes in flow 614), in flow 611. The current position information is acquired from the position information acquisition unit 212, and in the flow 612, the safety determination processing unit 215 of the mobile terminals 100a and 100b automatically includes the position information and the terminal information in the safety determination information. Send to.

  The safety determination information transmitted in the flow 612 includes, for example, terminal information such as a terminal ID and user information, position information of latitude and longitude, safety confirmation response (no response), sensor information (number of reactions, number of reactions), input operation Includes information (number of reactions, number of reactions) and location information positioning time. Note that the safety determination message may include a message indicating that there is no message input, default content, or the like in the safety determination information.

  In the flow 614, when the state determination processing number n is equal to or smaller than the predetermined processing number N (No in the flow 614), the process returns to the flow 604, and the safety confirmation application unit 214 repeats the state determination.

  It is assumed that the safety confirmation application unit 214 determines whether or not the data transmitted from the center device 120 to the mobile terminals 100a and 100b is a safety confirmation request and measures a predetermined time and a predetermined number of times.

FIG. 7 is an explanatory diagram of the format of the safety determination information.
The safety determination information includes terminal information (terminal ID, user), position information (latitude, longitude), safety confirmation response, sensor information (reaction frequency, non-reaction frequency) and input operation information (reaction frequency, non-reaction frequency). ) Including safety information, position information positioning time, and safety status message.

  Next, the operation of the center apparatus 120 will be described using the flowchart of FIG. FIG. 8 shows the operation of the center device 120 when a disaster occurs, for example, when an earthquake occurs.

  First, in flow 701, the disaster information processing unit 312 receives the emergency earthquake bulletin transmitted from the disaster information providing apparatus 130 via the communication I / F unit 300. The disaster information processing unit 312 transmits the emergency earthquake bulletin to the mobile terminals 100a and 100b in the area predicted to be affected by the earthquake. Next, in flow 702, the disaster information processing unit 312 receives from the disaster information providing apparatus 130 seismic intensity breaking news announced by an organization such as the Japan Meteorological Agency after the occurrence of an earthquake (for example, about one and a half minutes after the occurrence of the earthquake). . In the flow 703, the emergency earthquake warning dummy transmission unit 315 compares the area information obtained from the emergency earthquake warning and the seismic intensity warning, and the area where the earthquake early warning is not distributed even though the magnitude (magnitude) of the earthquake is large. Mobile terminals 100a and 100b are extracted (No in flow 703), a dummy emergency earthquake bulletin is transmitted to the mobile terminals 100a and 100b in flow 704.

  When the area information of the earthquake early warning and the seismic intensity warning match (Yes in the flow 703) or when the dummy emergency earthquake early transmission is completed, in the flow 705, the safety determination information processing unit 314 transmits the safety confirmation request. The safety confirmation request is transmitted to the mobile terminals 100a and 100b to which the earthquake early warning is distributed by the unit 313. In the flow 706, the safety determination information processing unit 314 receives information (safety determination information) related to the mobile terminals 100a and 100b and the mobile terminal user that the mobile terminals 100a and 100b transmit through the operation illustrated in FIG. . In flow 711, the safety determination information processing unit 314 predicts the urgency based on the received information. A detailed flow of urgent level prediction will be described later with reference to FIG. In flow 707, the safety determination information processing unit 314 determines the specific current location obtained from the safety determination information received from the mobile terminals 100a and 100b, the reception time of the safety determination information, the urgent prediction result, and the position information, as the center device. The information is registered in the safety information management table 325 in 120. After the registration, the safety determination information processing unit 314 sends the mobile terminals 100a, b, and the emergency contact information registered in advance in flow 708 to the rescue team, fire department, police, and other rescue organizations in flow 710. Send mobile terminal user information. The transmission information of the flows 708 and 710 can include, for example, all the information shown in FIG. 9 regarding the corresponding terminal information or appropriate part of information necessary for relief. Note that the order of the flows 708 and 710 is not limited to this, and either flow may be performed first. As described above, the center device 120 transmits information on the mobile terminal user, so that a rescuer, a rescue organization, and the like can identify a person who really needs relief, and suppress unnecessary safety confirmation. It leads to. When there is a safety confirmation response and “O”, the safety determination information processing unit 314 may not perform the processing of the flow 710.

  If it is within the predetermined time in the flow 709 (No in the flow 709), the safety determination information processing unit 314 repeats the processing from the transmission of the safety confirmation request in the flow 705. If the predetermined time has elapsed (Yes in flow 709), the process of the safety confirmation system is terminated.

  Here, a configuration example of the safety information management table in the center device 120 will be described with reference to FIG. The storage unit 320 of the center device 120 configures a safety information management table 325 as shown in FIG. 9, and manages safety determination information including location information of the mobile terminals 100a and 100b transmitted from the mobile terminals 100a and 100b. doing.

  In the safety information management table 325, as data extracted from the safety determination information, for each terminal ID of the mobile terminal, the user, location information (latitude, longitude), positioning time of the location information, safety information of the mobile terminal user (sensor Information (number of reactions, number of reactions), input operation information (number of reactions, number of reactions)), presence / absence of safety confirmation response (○, ×), safety status message from mobile terminal user (with safety confirmation response) Are registered in association with each other. Further, in the safety information management table 325, based on the data extracted from the safety determination information, for each terminal ID of the mobile terminal, the current location (region) specified from the location information and the safety information indicating the safety status of the mobile terminal user The urgency level estimated from the mobile phone 100a and the reception time of the safety determination information transmitted from the mobile terminals 100a and 100b are registered in association with each other. In addition, when specifying the present location (area) from the position information, the safety determination information processing unit 314 can obtain the current position (region) by referring to the map information included in the position information DB 321 based on the position information.

  This time, as an example, a table example in which the predetermined number of processing times N is 10 is shown. From this example, the portable terminal ID1 does not respond to the safety confirmation request, but since there is a response to the sensor 235 and the input operation unit 231, the safety determination information processing unit 314 is, for example, in an emergency state when the portable terminal user is in an emergency state It is possible to determine that there is a high possibility. Although the mobile terminal ID2 does not respond to the safety confirmation request and has reacted to the sensor 235 all ten times, the reaction to the input operation unit 231 cannot be confirmed even once, so the safety determination information processing unit 314 For example, it can be determined that the mobile terminal user may be in an emergency state. Since the portable terminal ID3 does not react to all of the safety confirmation request, the sensor 235, and the input operation unit 231, the safety determination information processing unit 314 may not include the portable terminal user near the portable terminal, for example. It can be judged that there is. Since the mobile terminal ID 4 can respond to the safety confirmation by itself, the safety determination information processing unit 314 can determine, for example, that the mobile terminal user is in a safe state. Although the portable terminal ID5 does not respond to the safety confirmation request and reacts to the sensor 235 four times, the reaction to the input operation unit 231 cannot be confirmed even once. It can be determined that there is a possibility that the mobile terminal user does not exist near the mobile terminal. The portable terminal ID 6 does not respond to the safety confirmation request at the first safety confirmation request, but responds to the sensor 235 and the input operation unit 231, so the safety determination information processing unit 314 uses, for example, a portable terminal It can be determined that there is a possibility that the person is in an emergency state, but at the second safety confirmation request, the sensor 235 has reacted seven times, but the input operation unit 231 has a reaction of 1 Since the information has not been confirmed many times, the safety determination information processing unit 314 can determine that the mobile terminal user may not exist near the mobile terminal, for example. Such determination is an example, and an appropriate determination method can be adopted depending on the type of disaster, region, time zone, and the like. A detailed flow of the urgent level prediction in FIG. 9 will be described later with reference to FIG.

  As described above, according to the configuration example of the safety information management table 325 in FIG. 9, after the disaster occurs, the center device 120 can manage the position information and the safety state for each individual. It becomes possible to take disaster countermeasures such as the period quickly and accurately. Further, by repeatedly performing the safety confirmation, it is possible to obtain the location information of the mobile terminal user and the presence or absence of changes in the safety state.

Each flow will be described in detail below.

(Flows 711 and 707)

Below, the determination method of the urgent degree prediction in the safety information management table shown in FIG. 9 is demonstrated.

  FIG. 10 shows the operation of the center device when determining the urgency prediction in the flow 711. First, in flow 1210, the safety determination information processing unit 314 acquires a safety confirmation response included in the safety determination information transmitted from the mobile terminals 100a and 100b. The safety determination information processing unit 314 terminates when there is a safety confirmation response (Yes) in the flow 1211 (Yes in the flow 1211), and when there is no safety confirmation response (×, etc.) (No in the flow 1211). Proceed to flow 1201. In the flow 1201, the safety determination information processing unit 314 acquires input operation information included in the safety determination information. When the safety determination information processing unit 314 can confirm from the input operation information in the flow 1202 that the input operation unit 231 has reacted (the number of reactions = 1) (Yes in the flow 1202), Let the urgency be I. On the other hand, when there is no response in the input operation unit 231 (the number of times of reaction ≠ 1) (No in the flow 1202), the safety determination information processing unit 314 acquires sensor information from the safety determination information in the flow 1204. The safety determination information processing unit 314 classifies the cases according to the number of times the sensor information has been reacted in the flow 1205, and associates them with the urgency levels II to V in the flows 1206 to 1209, respectively. It should be noted that the conditions for dividing cases in the flows 1206 to 1209 can be arbitrarily set and changed. After determining the respective urgent levels, the safety determination information processing unit 314 proceeds to a registration operation of the safety determination information including the urgent level prediction in the safety information management table 325 in the flow 707.

As an example, the urgency level is described as I to V this time, but the notation method is not limited to this. The determination of the urgent level prediction is merely an example, and an appropriate determination method can be adopted depending on the type of disaster, the region, the time zone, and the like.
In the above description, the urgent level prediction is determined by the flowchart. However, the urgency level prediction is determined for the sensor information and the input operation information, and the safety determination information processing unit 314 refers to the determination table to obtain the sensor. The urgency level prediction may be obtained based on the information and the input operation information.

(Flow 708)

FIG. 11 shows an emergency contact table 1301 in which a mobile terminal and a mobile terminal user are associated with an emergency contact. It is assumed that the emergency contact address table 1301 is included in the emergency contact information DB 324 of the center device 120. By registering the emergency contact information, the emergency contact information can be provided with information regarding safety as shown in FIG.
Although two emergency contacts are displayed this time, the number of emergency contacts that can be registered can be arbitrarily set.

In the flow 708, the safety determination information processing unit 314 can make an emergency contact by an appropriate communication means with reference to the emergency contact table 1301 to one or a plurality of emergency contacts obtained based on the terminal information. At that time, the safety determination information processing unit 314 can determine in advance whether or not to contact with reference to the safety information management table 325 as follows, for example.
・ Contact all mobile devices ・ Contact a mobile device that has received a safety confirmation response and one or more predefined emergency devices that have no safety confirmation response ・ A mobile device that has received a safety confirmation response Contacting the terminal ・ Contacting one or more predetermined emergency terminal mobile terminals without a safety confirmation response.

  FIG. 12 shows a display example of a safety information provision screen for an emergency contact after an earthquake occurs. The notification of information such as information regarding the safety of the mobile terminal user and the safety determination information is performed by the center device 120 receiving the safety determination information from the mobile terminals 100a and 100b, and then the emergency of the mobile terminals 100a and 100b registered in advance. It is sent to the contact. The example of FIG. 12 is message information for notifying information such as safety determination information to the emergency contact, and the safety determination information processing unit 314 extracts and creates each information as follows. That is, the message information is an automatic transmission mail about the terminal information of the safety information management table 325, whether there is a response (safety state message) to the safety confirmation from the safety confirmation response of the safety information management table 325, safety information management The current position information of the mobile terminals 100a and b from the current location of the table 325, the positioning time of the current position information of the mobile terminals 100a and b from the position information positioning time of the safety information management table 325, the sensor information of the safety information management table 325, and the input operation It includes extracted information such as a determination result of the safety state from the information, a message indicating the safety state from the safety state message of the safety information management table 325, and the like. As the current position information, in this example, the current position (region name) that can be specified from the latitude and longitude information obtained from the positioning result of the current position information is described, but a map may be displayed.

  Here, as the emergency contact information registered in the storage unit 320 of the center device 120, mobile mail addresses and telephones of the mobile terminals 100a and 100b of related parties such as family members, friends, and acquaintances who wish to send the safety confirmation determination result. It can be a number or the like. For example, when the destination information is a mobile mail address, the safety determination information processing unit 314 determines whether the safety confirmation determination result is a mobile mail, and when the destination information is a mobile phone number, the safety confirmation determination result. Can be sent by SMS (Short Message Service).

(Flow 710)

In flow 710, the safety determination information processing unit 314 can make an emergency call to a predetermined rescue organization or the like. At that time, the safety determination information processing unit 314 can determine in advance whether or not to contact with reference to the safety information management table 325 as follows, for example.
・ Contact all mobile terminals ・ Contact a mobile terminal that has received a safety confirmation response and one or more predetermined emergency prediction terminals that have no safety confirmation response. ”May be prioritized, such as giving priority to the rescue of mobile terminal users.)
・ Contacting a mobile terminal that has received a safety confirmation response ・ Contacting one or more predetermined emergency prediction terminals without a safety confirmation response.

5. Sequence variations

Next, the operation of the safety confirmation system will be described using the sequence diagram of FIG. In FIG. 13, as an example, it is assumed that the mobile terminal 100a and the base station 110a exist in a disaster area that has not yet received emergency earthquake bulletin, and the mobile terminal 100b and the base station 110b exist in a non-disaster area.

  Here, as an example, a case where there is a difference between the contents of the emergency earthquake warning and the seismic intensity warning will be described. Emergency earthquake alerts are analyzed and distributed immediately after the earthquake by the Japan Meteorological Agency and other organizations using the seismometer near the epicenter, but are only predictions. May be different. Even in such a case, it is required for the mobile terminals 100a and 100b and the mobile terminal user existing in the disaster area to confirm the safety of the mobile terminal user immediately after the disaster occurs.

  First, in sequence 1001, the earthquake information is provided from the disaster information providing apparatus 130 to the center apparatus 120. In the sequence 1002, the center device 120 simultaneously distributes the earthquake early warning via the base station 110a to the mobile terminals existing in the earthquake occurrence prediction area after obtaining the earthquake early warning. In this example, since the center device 120 determines that the mobile terminals 100a and 100b do not exist in the earthquake occurrence prediction area, the emergency earthquake bulletin is not distributed to the mobile terminals 100a and 100b.

  After the occurrence of the earthquake, in the sequence 1003, the earthquake information preliminary report is distributed from the disaster information providing apparatus 130 to the center apparatus 120. In sequence 1004, the center device 120 obtains the seismic intensity breaking news, and in sequence 1005, compares the emergency earthquake breaking news delivered from the disaster information providing device 130 before the earthquake occurrence with the seismic intensity breaking news delivered after the earthquake occurrence. It is assumed that the earthquake early warning non-delivery area is specified and the mobile terminal 100a exists in the non-delivery area. In this case, in the sequence 1006, the center device 120 transmits an emergency earthquake warning dummy to the mobile terminal 100a existing in the area not yet distributed. In sequence 1007, the mobile terminal 100 a existing in the disaster damage area receives a dummy emergency earthquake warning by the disaster information processing unit 213 through the communication I / F unit 200. In step 1008, the mobile terminal 100a that has received the earthquake early warning activates a safety confirmation application.

  Sequence 1009 to sequence 1019 perform the same operation as sequence 408 to sequence 418, and a detailed description thereof will be omitted.

  Next, the safety confirmation system will be described with reference to a block diagram showing the main part of the safety confirmation system of FIG. Here, a processing function is shown in which the center device 120 and the mobile terminals 100a and 100b operate in cooperation when a disaster occurs, for example, when an earthquake occurs.

  As illustrated in FIG. 14, the mobile terminals 100 a and 100 b are provided with a disaster information processing unit 213, a safety confirmation application unit 214, and a safety determination processing unit 215 as processing units of the system control unit 210.

The disaster information processing unit 213 receives disaster information such as emergency earthquake warnings distributed simultaneously from the center device 120 via the communication network 140 and the base stations 110a and 110b via the communication I / F unit 200 when a disaster occurs. It has a function to acquire.
Since the functions of the safety confirmation application unit 214, the safety determination processing unit 215, the communication I / F unit 200, the storage unit 220, and the user I / F unit 230 are the same as those in FIG. 5, detailed description thereof is omitted here.

  Next, the center device 120 is provided with an emergency earthquake early warning dummy transmission unit 315, a safety confirmation request transmission unit 313, and a safety determination information processing unit 314 as processing units of the system control unit 310.

The emergency earthquake bulletin dummy transmission unit 315 compares the emergency earthquake bulletin delivered before the earthquake and the earthquake intensity bulletin delivered after the earthquake, identifies the area where the emergency earthquake bulletin has not been delivered, and activates the safety confirmation application. It has a function of transmitting a dummy emergency earthquake warning.
The functions of the safety confirmation request transmission unit 313, the safety determination information processing unit 314, the communication I / F unit 300, the storage unit 320, and the user I / F unit 330 are the same as those in FIG. .

6). Modified example of flowchart

FIG. 15 is a modification of the operation flowchart of the mobile terminal.
In FIG. 15, processes other than the flow 604-1 to 604-3 are the same as the processes in FIG.

  In the flow 604-1, the safety confirmation application unit 214 requests the reception of the necessity of relief from the mobile terminal user. When an input indicating that no relief is required (relief is unnecessary in flow 604-1), the safety confirmation application unit 214 receives an input of a safety status message in flow 604-2, and after flow 605 is performed. Perform the process.

On the other hand, when an input indicating that relief is necessary (relief is required in flow 604-1), in flow 604-3, data other than the response to the safety confirmation response (◯) (for example, Δ or × Etc.), automatically input a message indicating that relief is necessary in the safety status message (or manually), and sensor information that allows the center device to determine that the emergency level prediction needs to contact the emergency status / relief organization, and Input operation information (for example, response = 1 as sensor information, reaction = 1 as input operation information) is set, and the flow proceeds to flow 611. If no input is made within the predetermined reception time (no input in the flow 604-1), the safety confirmation application unit 214 performs the processing after the flow 607.
Thereby, the center apparatus can judge as an emergency level prediction (for example, emergency level = 1) which needs to contact a rescue organization according to the flowchart of FIG.

7). Effects of the embodiment

In the present embodiment, in the event of a disaster, the mobile terminal uses a function such as a sensor built in the mobile terminal to more accurately determine the state of the mobile terminal user, and the determination result and position information are automatically detected. Thus, the status of the mobile terminal user can be notified to the rescue team or the contact information registered in advance. In this way, by identifying the people who really need relief, the limited number of people on the rescue side can be used effectively, and by disseminating information, unnecessary safety confirmation can be suppressed and congestion due to access concentration can be prevented. It also becomes.
According to the present embodiment, by automatically and repeatedly collecting information about the mobile terminal user, it is possible to identify a person who really needs relief and grasp the state change of the mobile terminal user. be able to.
