[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are designated by the same reference numerals, and for clarity of explanation, duplicate explanations will be omitted as necessary.

[0012] <Embodiment 1> FIG. 1 is a block diagram showing the configuration of a safety confirmation support device 1. The safety confirmation support device 1 is an information processing device that supports safety confirmation of a group of people registered in a target area in the event of a disaster. It is assumed that a local government or the like uses a predetermined information system to register and manage information on communication terminals for confirming the safety of residents and others in each area in the event of a disaster. The safety confirmation support device 1 is assumed to be able to access the information system or to be part of the information system.

[0013] The target group is a collection of residents of each area or people who stay there during the day. The target group includes at least people requiring support, such as the elderly and people with disabilities. The target group may also include support candidates who have the potential to support those requiring support. If a support candidate is able to support a specific person requiring support during a disaster, they will provide various types of support during a disaster, such as accompanying the specific person requiring support to an evacuation shelter. In addition, those requiring support and support candidates will respond to a "request to register safety status" notified to their communication terminal when a disaster occurs, by using their communication terminal to confirm their own safety status. Furthermore, in response to a "request to register whether they can provide support to a person requiring support" notified to their communication terminal when a disaster occurs, support candidates will respond to a "request to register whether they can provide support to a person requiring support" notified to their communication terminal by using their communication terminal to confirm whether they are able to provide support to the person requiring support (whether they can provide support). By responding that they can provide support, support candidates become supporters. Supporters provide support, such as checking the safety status of the person requiring support.

[0014] The safety confirmation support device 1 includes a first notification unit 11, an identification unit 12, and a second notification unit 13. In the event of a disaster, the first notification unit 11 sends a safety confirmation notification to each communication terminal of a target group registered within a target area using a first communication method. The "first communication method" is a communication method for sending a push notification containing text information from the safety confirmation support device 1 to each communication terminal via a first communication network. The "first communication method" may be, for example, a wireless communication method via the Internet network, but is not limited to this. Therefore, in the event of a disaster, the first notification unit 11 sends a safety confirmation notification to each communication terminal of a target group registered within a target area via the first communication network. In addition, the push notification containing text information may be, for example, a message notification or an incoming call notification to a disaster application installed on the communication terminal. However, the push notification is not limited to these. The "safety confirmation notification" includes the above-mentioned "request to register safety status" and "request to register whether support is available for a person requiring support."

[0015] The identification unit 12 identifies a partial area in a target area where the response rate to the safety confirmation notification is lower than a threshold value among a plurality of partial areas within the target area. That is, the identification unit 12 calculates the response rate by tallying up responses to the safety confirmation notification from each communication terminal for each partial area. Then, the identification unit 12 identifies a partial area where the calculated response rate is lower than a threshold value.

[0016] The second notification unit 13 sends a reconfirmation notification of a notification regarding safety confirmation to the specified partial area via a second communication method different from the first communication method. The "second communication method" is a communication method via a second communication network. The second communication network is, for example, a disaster prevention radio broadcasting network, a mobile phone network, or a communication network used by a national or local emergency warning system. Therefore, the "second communication method" may be a communication method via a second communication network different from the first communication network used in the first communication method. In other words, the second notification unit 13 sends a notification regarding safety confirmation to the specified partial area via the second communication network. The destination of the reconfirmation notification may be a communication terminal of a group of targets registered in the specified partial area.

[0017] 2 is a flowchart showing the flow of the safety confirmation support method. First, in the event of a disaster, first notification unit 11 sends a safety confirmation notification to each communication terminal of a target group registered within a target area using a first communication method (S1). Next, identification unit 12 identifies a partial area within the target area where the response rate to the safety confirmation notification is lower than a threshold (S2). Then, second notification unit 13 sends a reconfirmation notification of the safety confirmation notification to the identified partial area using a second communication method different from the first communication method (S3).

[0018] In this manner, in this embodiment, the target area is narrowed down to a partial area where the response rate to the safety confirmation notification sent to each communication terminal by the first communication method is lower than a threshold, and a reconfirmation notification is sent to the narrowed down partial area by a second communication method different from the first communication method. Therefore, reconfirmation notifications can be sent efficiently and quickly to persons needing support and support candidates in areas with many non-respondents. This can help quickly collect information on the safety status of disaster victims when a disaster occurs.

[0019] The safety confirmation support device 1 includes a processor, a memory, and a storage device (not shown). The storage device stores a computer program that implements the processing of the safety confirmation support method shown in Fig. 2, for example. The processor then loads the computer program from the storage device into the memory and executes the computer program. This allows the processor to implement the functions of a first notification unit 11, an identification unit 12, and a second notification unit 13.

[0020] Alternatively, each component of the safety confirmation support device 1 may be realized by dedicated hardware. Furthermore, some or all of the components of each device may be realized by general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or by multiple chips connected via a bus. Some or all of the components of each device may be realized by a combination of the above-mentioned circuits, etc., and programs. Furthermore, a CPU (Central Processing Unit), GPU (Graphics Processing Unit), FPGA (Field-Programmable Gate Array), quantum processor (quantum computer control chip), etc., may be used as the processor.

[0021] Furthermore, when some or all of the components of the safety confirmation support device 1 are realized by multiple information processing devices, circuits, etc., the multiple information processing devices, circuits, etc. may be centrally or decentralized. For example, the information processing devices, circuits, etc. may be realized as a client-server system, a cloud computing system, or the like, each connected via a communication network. Furthermore, the functions of the safety confirmation support device 1 may be provided in a SaaS (Software as a Service) format.

[0022] <Embodiment 2> FIG. 3 is a block diagram showing the overall configuration of a safety confirmation support system 1000. The safety confirmation support system 1000 is an information system for supporting safety confirmation of a group of people registered in a target area in the event of a disaster. The safety confirmation support system 1000 includes a safety confirmation support device 100, local speakers 210, . . . 2n0 (n is a natural number equal to or greater than 2), and communication terminals 211, 212, . . . 2n1, and 2n2. The safety confirmation support device 100 and the communication terminals 211 to 2n2 are communicatively connected via a network N1. Here, the network N1 is a communication network including wireless. The network N1 is, for example, the Internet, but is not limited to this. Furthermore, the safety confirmation support device 100 and the local speakers 210 to 2n0 are communicatively connected via a network N2. Here, the network N2 is a communication network including wireless, different from the network N1. The network N2 may be, for example, a disaster prevention radio broadcasting network, but is not limited to this.

[0023] In FIG. 3, a disaster is assumed to have occurred in a target area R. The target area R is divided into a plurality of partial areas R1 to Rn and managed. For example, a local speaker 210 is installed in the partial area R1. In addition, in the partial area R1, persons requiring support U11 and support candidates U12 are registered in the information system of a local government as targets for confirmation of their safety status in the event of a disaster.

[0024] Persons requiring support U11 are people who have difficulty evacuating independently during a disaster, such as the elderly or people with disabilities. Therefore, Persons requiring support U11 are recognized by local governments and local representatives as people who will receive support (subsidies, etc.) for evacuation and daily life during a disaster from support candidates U12 who responded that they are available to provide support. Therefore, local governments, etc. need to understand the safety status of Persons requiring support U11 during a disaster. Therefore, Persons requiring support U11 are registered on a list of people requiring support in the event of a disaster in the local government's information system, etc. Note that a local representative is at least a person who coordinates supporters, such as local welfare officers, for each region. The local representative, for example, assigns persons requiring support to supporters.

[0025] Support candidate U12 is a person who, when able to support person requiring support U11 in the event of a disaster, will act as a supporter by checking the safety of person requiring support U11, accompanying them during evacuation, providing support for daily life, etc. Support candidate U12 is registered on a list of candidates for support in the event of a disaster in the local government's information system, etc.

[0026] The communication terminals 211 and 212 are portable information terminals on which a disaster application is installed and which are capable of wireless communication via the network N1. In the event of a disaster, the communication terminals 211 and the like receive a notification from the safety confirmation support device 100 by PUSH notification via the disaster application. For example, upon receiving a PUSH notification, the communication terminals 211 and the like play a ringtone or vibrate, display a notification message on the screen, or the like.

[0027] The communication terminal 211 is registered in the safety confirmation support device 100 as a communication terminal that responds to the safety status of the person requiring support U11 who is a target of the partial area R1. The communication terminal 211 is usually carried by the person requiring support U11 or is located nearby. In the event of a disaster, the communication terminal 211 receives a request to register the safety status from the safety confirmation support device 100 by push notification via the network N1 and a disaster application. The communication terminal 211 accepts the registration (response) of the safety status in response to an operation by the person requiring support U11, and transmits the response to the safety status to the safety confirmation support device 100 via the disaster application and the network N1.

[0028] The communication terminal 212 is registered in the safety confirmation support device 100 as a communication terminal that responds to the safety status of the support candidate U12, who is a target of the partial area R1, and whether or not to provide support to the person in need of support. Furthermore, the communication terminal 212 is normally carried by the support candidate U12 or is located nearby. During a disaster, the communication terminal 212 receives a request to register the safety status and a request to register whether or not to provide support to the person in need of support from the safety confirmation support device 100 via the network N1 and a disaster application by push notification. The communication terminal 212 accepts the registration (response) of the safety status in response to an operation by the support candidate U12, and transmits the response to the safety status to the safety confirmation support device 100 via the disaster application and the network N1. Furthermore, the communication terminal 212 accepts the registration (response) of whether or not to provide support to the person in need of support in response to an operation by the support candidate U12, and transmits the response to the safety confirmation support device 100 via the disaster application and the network N1.

[0029] The local speaker 210 is a speaker that outputs a voice message for reconfirming a notification regarding safety confirmation by disaster prevention radio broadcasting via the network N2 (disaster prevention radio broadcasting network) from the safety confirmation support device 100. The siren and voice output from the local speaker 210 are diffused mainly in the partial area R1.

[0030] Furthermore, in a partial area other than the partial area R1 within the target area R, for example, partial area Rn, a local speaker 2n0 is installed. In the partial area Rn, a person requiring support Un1, a support candidate Un2, etc. are registered in a local government information system or the like as targets for confirmation of safety status in the event of a disaster. The person requiring support Un1 and the support candidate Un2 are similar to the above-described person requiring support Un1 and support candidate Un2, except that they are registered as targets in the partial area Rn. Furthermore, the communication terminal 2n1 is registered in the safety confirmation support device 100 or the like as a communication terminal for confirming the safety of the person requiring support Un1, who is a target in the partial area Rn. Other aspects of the communication terminal 2n1 are similar to the above-described communication terminal 211. Furthermore, the communication terminal 2n2 is registered in the safety confirmation support device 100 or the like as a communication terminal for confirming the safety status of the support candidate Un2, who is a target in the partial area Rn, and for responding to the support-requiring person whether or not to provide support. Other aspects of the communication terminal 2n2 are similar to the above-described communication terminal 212.

[0031] The local speaker 2n0 is a speaker that outputs a voice message to reconfirm a notification regarding a safety confirmation from the safety confirmation support device 100 via the network N2 disaster prevention radio broadcast. The siren and voice output from the local speaker 2n0 are spread mainly within the partial area Rn.

[0032] FIG. 4 is a block diagram showing the configuration of the safety confirmation support device 100. The safety confirmation support device 100 is an information processing device for supporting safety confirmation of a group of target persons registered in a target area in the event of a disaster. The safety confirmation support device 100 includes a storage unit 110, a setting unit 121, a first communication unit 122, a counting unit 123, an identification unit 124, and a second communication unit 125. The storage unit 110 includes, for example, a non-volatile storage device such as a hard disk or flash memory, and a memory such as RAM, that is, a volatile storage device. The storage unit 110 stores area information 111, resident information 112, and setting definition information 113.

[0033] The area information 111 includes a plurality of sets of partial area information 1111 and disaster prevention radio speaker information 1112. The partial area information 1111 is information related to a partial area. For example, the partial area information 1111 may be identification information, a name, an address range, etc. of the partial area. The disaster prevention radio speaker information 1112 is destination information, etc. for transmitting disaster prevention radio broadcasts to a local speaker installed in the partial area corresponding to the partial area information 1111. For example, if the partial area information 1111 is partial area R1, the disaster prevention radio speaker information 1112 may be, but is not limited to, location information of the local speaker 210 and the frequency of radio waves that the local speaker 210 can receive. Note that the storage unit 110 may store two or more pieces of area information 111.

[0034] The resident information 112 is information about a group of subjects (residents, etc.) registered in a target area corresponding to the area information 111. The resident information 112 is information that associates at least a residential area 1121, subject information 1122, attribute information 1123, and communication terminal information 1124. The residential area 1121 is information that can identify at least the partial area to which the subject belongs. Specifically, the residential area 1121 is information equivalent to the partial area information 1111 described above, or information that can uniquely identify the partial area information 1111. Alternatively, the residential area 1121 may be information that indicates an address. The subject information 1122 includes information that can uniquely identify the subject. The subject information 1122 may be, for example, the subject's identification information, name, date of birth, etc. The attribute information 1123 includes information that indicates whether the subject is a person requiring support or a support candidate. The communication terminal information 1124 includes address information of a communication terminal carried by the subject and on which a disaster application is installed. That is, the communication terminal information 1124 is information used as a destination for notifying a request to register the safety status and a request to register whether support is available to the person in need of support. The storage unit 110 stores at least one piece of resident information 112 whose attribute information 1123 is a person in need of support, and one or more pieces of resident information 112 whose attribute information 1123 is a support candidate.

[0035] The setting definition information 113 is information that defines various setting values ​​used in the safety confirmation support processing according to the present disclosure for each alert level. The setting definition information 113 is a set of multiple alert levels 1131 and setting values ​​1132. The alert level 1131 is information indicating the disaster alert level transmitted from the information system of a public institution. The setting values ​​1132 are setting values ​​such as the threshold for the response rate, the interval for counting the response rate, and the interval for specifying the target area for reconfirmation notifications for the associated alert level.

[0036] The "response rate" includes the "safety status response rate," which is the response rate to requests to register safety status, and the "support availability response rate," which is the response rate by support candidates to requests to register whether they are able to provide support to those in need of support. The safety status response rate is the ratio of the number of people who responded to safety status requests per total number of subjects. The safety status response rate may also be the ratio of the number of people who responded to safety status requests of those in need of support per total number of those in need of support. The number of people who responded to safety status requests of those in need of support in the safety status response rate includes the number of people who responded to the safety status of those in need of support after the supporter checked their safety status.

[0037] The threshold for the response rate according to the alert level should be set lower the higher the alert level. For example, for alert level 1, the threshold for the safety status response rate should be 50%, and the threshold for the support availability response rate should be 40%. In this example, for alert level 2, which is a higher level of alert than alert level 1, the threshold for the safety status response rate should be 40%, and the threshold for the support availability response rate should be 30%. Note that the thresholds for the response rate according to the alert level are not limited to these.

[0038] The setting unit 121 accepts registration (setting) of a pair of an alert level 1131 and a setting value 1132 from an administrator or the like of the safety confirmation support device 100, and registers the accepted pair of the alert level 1131 and the setting value 1132 in the setting definition information 113 in the storage unit 110. Furthermore, when disaster alert level information is received when a disaster occurs, the setting unit 121 may set various setting values ​​according to the alert level. Specifically, the setting unit 121 determines the setting value 1132 associated with the alert level 1131 of the disaster that has occurred from the setting definition information 113, and sets the determined setting value in a memory (not shown) or the like as a response rate threshold, a counting interval, a specific interval, or the like.

[0039] The first communication unit 122 is an example of the above-mentioned first notification unit 11. The first communication unit 122 transmits a registration request for safety status to each communication terminal of the subjects registered in the affected area of ​​the disaster that has occurred, via the network N1. The first communication unit 122 transmits a "registration request for safety status" to the communication terminal of at least subjects whose attribute information 1123 is "person in need of support" among the subjects registered in the affected area. The first communication unit 122 also transmits a "registration request for whether support is available for a person in need of support" to the communication terminal of subjects whose attribute information 1123 is "support candidate" among the subjects registered in the affected area of ​​the disaster that has occurred. The first communication unit 122 pushes the above-mentioned registration request message or the like to each communication terminal via the network N1.

[0040] The tallying unit 123 receives responses to the registration request from each communication terminal via the network N1, and tally (calculate) a safety status response rate and a support availability response rate for each partial region. At this time, the tallying unit 123 may classify the received responses by partial region and temporarily store them in the storage unit 110. Then, the tallying unit 123 may tally the response rate for each partial region from the responses stored in the storage unit 110 according to a predetermined tallying interval. The predetermined tallying interval may be a tallying interval set by the setting unit 121 according to the alert level. Note that the tallying unit 123 may be realized as a part of the function of the identification unit 124, which will be described later.

[0041] The identification unit 124 is an example of the identification unit 12 described above. The identification unit 124 determines whether the response rate for each partial area is lower than a threshold. Then, the identification unit 124 identifies partial areas in which the response rate is lower than the threshold. In particular, the identification unit 124 may determine whether the response rate for each partial area is lower than the threshold according to a predetermined determination interval. Here, the predetermined determination interval is the "identification interval for the target area for the reconfirmation notification" described above. That is, the predetermined determination interval may be a specific interval set by the setting unit 121 according to the alert level. Furthermore, the threshold may be set in advance or may be set by the setting unit 121 according to the alert level. That is, the identification unit 124 may identify partial areas in which the response rate is lower than a threshold determined according to the disaster alert level. This makes it possible to appropriately select target areas for the reconfirmation notification according to the alert level. For example, a low response rate indicates a high probability of severe damage in the target partial area, and thus indicates a high urgency of providing support (safety confirmation) to those in need of support. As described above, the setting unit 121 sets the threshold relatively low when the alert level is high. Therefore, the identifying unit 124 can identify a partial area where the response rate is lower than a relatively low threshold as an area where a reconfirmation notification is highly necessary. Therefore, it is possible to support the safety confirmation promptly by a reconfirmation notification, which will be described later.

[0042] The second communication unit 125 is an example of the above-mentioned second notification unit 13. The second communication unit 125 issues a reconfirmation notice of the notification regarding safety confirmation using disaster prevention radio broadcasting targeted at the identified partial area as a second communication method. That is, the second communication unit 125 issues a reconfirmation notice of the notification regarding safety confirmation by a local speaker in the partial area identified by the identification unit 124. Specifically, the second communication unit 125 instructs the local speaker in the partial area identified by the identification unit 124 to output a reconfirmation notice of the notification regarding safety confirmation via the network N2.

[0043] Furthermore, the second communication unit 125 may send a reconfirmation notification with notification content determined according to the response rate in the specified partial area. In other words, the notification content in the reconfirmation notification may be determined according to the response rate. This allows the reconfirmation notification to be sent with a message or the like that encourages the user to respond to the safety confirmation request when the response rate is low. This is expected to improve the response rate in response to the reconfirmation notification.

[0044] 5 is a block diagram showing the hardware configuration of the safety confirmation support apparatus 100. The safety confirmation support apparatus 100 includes a memory 101, a processor 102, and a network interface 103.

[0045] The memory 101 is configured by a combination of volatile memory and non-volatile memory. The volatile memory is, for example, a volatile storage device such as RAM, and is a storage area for temporarily storing information when the processor 102 is operating. The non-volatile memory is, for example, a non-volatile storage device such as a hard disk or flash memory. The memory 101 stores at least a computer program that implements the processing of the safety confirmation support method of the safety confirmation support device 100 according to the present disclosure. Note that the memory 101 may include storage located away from the processor 102. In this case, the processor 102 may access the memory 101 via an I / O (Input / Output) interface, not shown.

[0046] The processor 102 is a control device that controls each component of the safety confirmation support device 100. The processor 102 reads and executes software (computer programs) from the memory 101. As a result, the processor 102 realizes the functions of a setting unit 121, a first communication unit 122, a counting unit 123, an identifying unit 124, and a second communication unit 125. That is, the processor 102 performs processing of the safety confirmation support method according to the present disclosure. The processor 102 may be, for example, a microprocessor, an MPU (Multi Processing Unit), or a CPU (Central Processing Unit). The processor 102 may also include multiple processors.

[0047] The network interface 103 may be used to communicate with network nodes. The network interface 103 has a function capable of communicating with each of the communication networks of the networks N1 and N2. The network interface 103 may include, for example, a network interface card (NIC) conforming to the IEEE 802.3 series. IEEE stands for Institute of Electrical and Electronics Engineers. The network interface 103 may also include a wireless local area network (LAN), a wired LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), etc. Furthermore, the network interface 103 is also compatible with communication standards for disaster prevention radio broadcasting networks.

[0048] 6 is a flowchart showing the flow of the safety confirmation support process. First, the safety confirmation support device 100 receives disaster alert level information when a disaster occurs (S21). For example, the safety confirmation support device 100 may receive disaster alert level information transmitted from an information system of a public institution. Then, the safety confirmation support device 100 determines setting values ​​according to the alert level (S22). At this time, as described above, the setting unit 121 sets the response rate threshold, counting interval, specific interval, etc., which are setting values ​​associated with the alert level, in a memory or the like.

[0049] Then, when a disaster occurs, the safety confirmation support device 100 sends a push notification of a safety registration request and a support availability registration request (S23). Specifically, the safety confirmation support device 100 transmits a registration request for the safety status and the availability of support for the person requiring support to each communication terminal of the target group registered in the target area via the network N1. Note that steps S21 and S22 may be executed before step S25. In that case, the safety confirmation support device 100 may execute step S23 at its own discretion when a disaster occurs.

[0050] Thereafter, the safety confirmation support device 100 receives responses to each registration request from each communication terminal as needed (S24). Then, the safety confirmation support device 100 tallies the response rate for each partial region (S25). Then, the safety confirmation support device 100 determines whether the response rate for each partial region is equal to or greater than a threshold (S26). At this time, if the response rate does not satisfy both the threshold for the safety status response rate and the threshold for the support availability response rate, the safety confirmation support device 100 may determine that the response rate for that partial region is not equal to or greater than the threshold. In other words, if the safety status response rate for a specific partial region is lower than the threshold (for the safety status response rate) and the support availability response rate for that partial region is lower than the threshold (for the support availability response rate), the safety confirmation support device 100 may determine that the partial region is to be reminded (reconfirmed). Alternatively, if the response rate does not satisfy either the threshold for the safety status response rate or the threshold for the support availability response rate, the safety confirmation support device 100 may determine that the response rate in that partial area is not equal to or greater than the threshold. In other words, the safety confirmation support device 100 may determine that the response rate in a specific partial area is not equal to or greater than the threshold when the safety status response rate in that partial area is equal to or greater than the threshold and the support availability response rate is lower than the threshold, or even when the safety status response rate is lower than the threshold and the support availability response rate is equal to or greater than the threshold.

[0051] For partial areas where the response rate is equal to or greater than the threshold in step S26, the safety confirmation support device 100 excludes the partial areas from the reminder target. On the other hand, for partial areas where the response rate is equal to or greater than the threshold in step S26, the safety confirmation support device 100 identifies the partial areas as the reminder target (S27). Then, the safety confirmation support device 100 issues a reconfirmation notification through the local speaker of the identified partial area (S28).

[0052] In this way, this embodiment efficiently narrows down the disaster-affected area to a sub-region where the response rate to safety confirmation notifications is lower than a threshold, and effectively sends reconfirmation notifications via disaster prevention radio broadcasts. In particular, during a disaster, communication infrastructure such as wireless base stations may not function due to malfunctions, etc., so by narrowing down reconfirmation notifications to a sub-region with a low response rate via network N2, which is different from network N1, it becomes easier to efficiently collect responses from those in need of support and support candidates. This allows government agencies and other organizations to more quickly grasp the safety status of those in need of support. Furthermore, by allowing government agencies and other organizations to more quickly grasp the availability of support candidates, local representatives and government officials can more easily manage the support status. Furthermore, by having many people in need of support register their safety status themselves, the burden on supporters is reduced.

[0053] <Embodiment 3> FIG. 7 is a block diagram showing the overall configuration of the safety confirmation support system 1000a. In the safety confirmation support system 1000a, the safety confirmation support device 100 is replaced with 100a and the network N2 is replaced with N2a, as compared to the safety confirmation support device 100 shown in FIG. 3 above. The network N2a may be, for example, a mobile phone network, but is not limited to this. Therefore, the second communication method may be a call to the communication terminal of the non-respondent. Furthermore, each of the communication terminals 211, etc., can communicate using both the first communication method and the second communication method. That is, each of the communication terminals 211, etc., can communicate via both the networks N1 and N2. Therefore, each of the communication terminals 211, etc., can receive a push notification regarding safety confirmation from the safety confirmation support device 100a via the network N1, and can receive a reconfirmation notification via a phone call via the network N2.

[0054] FIG. 8 is a block diagram showing the configuration of the safety confirmation support device 100a. Unlike the safety confirmation support device 100a shown in FIG. 4, the disaster prevention radio speaker information 1112 does not necessarily need to be associated with the partial area information 1111. Furthermore, the communication terminal information 1124a in the resident information 112 may include a telephone number. The second communication unit 125a sends a reconfirmation notification to the communication terminal of a non-responding person who is registered in the identified partial area and has not responded to the safety confirmation notification using a second communication method. Specifically, the second communication unit 125a transmits a voice message of the reconfirmation notification to the communication terminal of the non-responding person via the network N2. Furthermore, the second communication unit 125a may send the reconfirmation notification using notification content determined according to the attribute information of the non-responding person. For example, the voice message of the reconfirmation notification may be different for the person requiring support and the support candidate. This allows the appropriate reconfirmation notification to be sent depending on the recipient of the communication terminal, thereby improving the response rate. The second communication unit 125a may also send a reconfirmation notification with notification content determined according to the response rate in the identified partial area.

[0055] FIG. 9 is a flowchart illustrating the flow of the safety confirmation support process. Here, differences from FIG. 6 will be mainly described. In step S26, if the response rate for a specific partial area is equal to or greater than a threshold, the safety confirmation support device 100a identifies non-responding individuals in the partial area to be reminded (S27a). Specifically, the safety confirmation support device 100a identifies non-responding individuals from among individuals registered in the partial area to be reminded, excluding the respondents received in step S24. The safety confirmation support device 100a then sends a reconfirmation notification to the communication terminals of the identified non-responding individuals by calling them via the network N2 (S28a). This allows the reconfirmation notification to be sent directly to the non-responding individuals, potentially improving the response rate. Furthermore, the reconfirmation notification is sent using a communication method (communication network) different from that used for the registration request (registration notification) in step S23, increasing the probability that communication terminals that did not receive the initial registration notification will receive the reconfirmation notification. Additionally, the third embodiment achieves the same effects as the second embodiment described above.

[0056] <Other embodiments> The identifying unit may aggregate the response rates at an aggregation interval determined according to the disaster alert level, and identify partial areas where the aggregated response rates are lower than a threshold. For example, if the alert level is higher than a certain value, the aggregation interval may be set shorter than when the alert level is lower than the certain value, thereby sending reconfirmation notifications more quickly to partial areas where the urgency of support is high, making it easier to grasp the safety status and availability of support.

[0057] Furthermore, the above-mentioned identifying unit may identify partial areas where the response rate is lower than a threshold at a specific interval determined according to the disaster alert level. For example, when the alert level is higher than a certain value, the specific interval may be set shorter than when the alert level is lower than the certain value, thereby sending reconfirmation notifications more quickly to partial areas where the urgency of support is high, making it easier to grasp the safety status and whether support is possible.

[0058] The second communication network, which is different from the first communication network, may be, for example, a communication network or a dedicated line that can be used by a national or local government for an emergency alert system.
