Description

[Technical Field]

[0001] The present invention relates to an emergency call support device, an emergency call support method, and an emergency call support program. [Background Art]

[0002] Emergency responses based on a large number of emergency calls (such as 119 calls) are carried out every day. In emergency response, the survival rate of an emergency patient can be improved by performing appropriate first aid by people at the site before emergency service personnel arrive at the site where the emergency patient is located. Therefore, technologies that support people at the site in performing appropriate first aid are expected.

[0003] In relation to the above technology, Patent Document 1 discloses a mobile communication system that prompts a reporter who reports an emergency patient to obtain an AED (Automated External Defibrillator). This system includes a database in which the locations of AEDs are registered, and acquires position information of the reporter's terminal when a report is received from the reporter's terminal. This system extracts location information of the AED closest to the position of the reporter's terminal from the acquired position information and the database. This system transmits the extracted AED location information to the reporter's terminal, communicates with the mobile terminal included in the AED, and starts notification to the surroundings via the notification function included in the AED.

[0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2009-224967 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] For example, if an emergency call is made to report a medical emergency, and a person familiar with emergency medical procedures who is near the scene of the emergency call is aware that such an emergency call has been made, they can provide more appropriate support for the emergency medical treatment of the patient. Alternatively, if an emergency call is made to report a fire, and a person near the scene of the emergency call is aware that such an emergency call has been made, residents living near the scene can more appropriately carry out firefighting activities or evacuation actions. In other words, when an emergency call is made, the challenge is to support people near the scene of the emergency call so that they can quickly recognize the event indicated by the emergency call. Patent Document 1 does not specifically address this challenge.

[0006] The primary objective of this invention is to assist people near the scene of an emergency call in quickly recognizing the event indicated by the emergency call. [Means for solving the problem]

[0007] An emergency call support device according to one aspect of the present invention comprises: acquisition means for acquiring location information of a plurality of terminal devices; call source identification means for acquiring an emergency call made from any of the terminal devices and identifying the call source terminal device that made the emergency call; notification destination identification means for identifying a notification destination terminal device among the terminal devices other than the call source terminal device whose proximity to the call source terminal device, as indicated by the location information, satisfies the notification destination identification criteria; and notification means for notifying the notification destination terminal device of the emergency call and the location information relating to the call source terminal device.

[0008] In addition to achieving the above objective, an emergency notification support method according to one aspect of the present invention involves an information processing device that acquires location information of a plurality of terminal devices, acquires an emergency notification made from any of the terminal devices, identifies the terminal device that made the emergency notification, identifies a destination terminal device among the terminal devices other than the source terminal device that satisfies the criteria for identifying a destination terminal device, and notifies the destination terminal device of the emergency notification and the location information relating to the source terminal device.

[0009] Furthermore, in order to achieve the above objectives, an emergency call support program according to one aspect of the present invention causes a computer to execute: an acquisition process to acquire location information of a plurality of terminal devices; a source identification process to acquire an emergency call made from any of the terminal devices and identify the source terminal device that made the emergency call; a destination identification process to identify a destination terminal device among the terminal devices other than the source terminal device whose proximity to the source terminal device, as indicated by the location information, satisfies the destination identification criteria; and a notification process to notify the destination terminal device of the emergency call and the location information relating to the source terminal device.

[0010] Furthermore, the present invention can also be realized using a computer-readable, non-volatile recording medium on which the emergency notification support program (computer program) is stored. [Effects of the Invention]

[0011] The present invention can help people near the scene where an emergency call was made to quickly recognize the event indicated by the emergency call. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0014] <First Embodiment> Figure 1 is a block diagram showing the configuration of an emergency call support system 1 according to a first embodiment of the present invention. The emergency call support system 1 broadly comprises an emergency call support device 10, a plurality of terminal devices 20, a management terminal device 30, and a team member terminal device 40. The emergency call support device 10, the plurality of terminal devices 20, the management terminal device 30, and the team member terminal device 40 are connected to each other via a communication network (not shown), such as the Internet.

[0015] The multiple terminal devices 20, the management terminal device 30, and the member terminal device 40 are, for example, information processing devices such as personal computers, tablet devices, and smartphones.

[0016] The multiple terminal devices 20 are devices used by their users when making emergency calls 172 (such as 119 calls or 110 calls) to, for example, a fire station or police station, or when confirming information transmitted from the emergency call support device 10. Emergency calls 172 include, for example, reports of medical emergencies, reports of fires, and reports of incidents such as riots. The multiple terminal devices 20 include the call source terminal device 20-1, the notification destination terminal device 20-2, and other terminal devices 20-3, which will be described later.

[0017] The management terminal device 30 is a device used when a user of the emergency call support device 10 (for example, a staff member of a fire station or a police station) inputs information to the emergency call support device 10 or checks information output from the emergency call support device 10.

[0018] The member terminal device 40 is a device used by members (including emergency medical technicians, firefighters, police officers, etc.) who are dispatched to the site where the event indicated by the emergency call 172 has occurred in response to the emergency call 172 made from the reporter terminal device 20-1 when they are dispatched to the site.

[0019] The emergency call support device 10 is an information processing device such as a server used by, for example, a fire station or a police station. The emergency call support device 10 includes an acquisition unit 11, a reporter identification unit 12, a notification destination identification unit 13, a notification unit 14, an input / output unit 15, a determination unit 16, and a storage unit 17. The acquisition unit 11, the reporter identification unit 12, the notification destination identification unit 13, the notification unit 14, the input / output unit 15, and the determination unit 16 are examples of an acquisition means, a reporter identification means, a notification destination identification means, a notification means, an input / output means, and a determination means, respectively.

[0020] The storage unit 17 is a storage device such as a RAM (Random Access Memory) 903 or a hard disk 904, which will be described later with reference to FIG. 5. The storage unit 17 stores position information 171, the emergency call 172, notification destination identification criteria 173, notification destination registration information 174, first aid treatment information 175, and false alarm determination criteria 176. These pieces of information stored in the storage unit 17 will be described later.

[0021] The acquisition unit 11 acquires position information 171 of each terminal device 20 from each of the plurality of terminal devices 20 at any time or at a predetermined timing. The position information 171 is information that can be acquired by, for example, GNSS (Global Navigation Satellite System). The acquisition unit 11 associates the acquired position information 171 with information capable of identifying (specifying) the terminal device 20, and stores the associated information in the storage unit 17. The information capable of identifying the terminal device 20 is, for example, information representing a MAC (Media Access Control) address, an IP (Internet Protocol) address, a telephone number, or the like.

[0022] The report source specifying unit 12 acquires an emergency report 172 made from a report source terminal device 20-1, which is one of the terminal devices 20. The emergency report 172 is, for example, a 119 call to a fire station, a 110 call to a police station, or the like. The report source specifying unit 12 can acquire the emergency report 172 from a system that receives emergency reports 172 at a fire station, a police station, or the like.

[0023] The report source specifying unit 12 stores the acquired emergency report 172 in the storage unit 17. The emergency report 172 includes, for example, information representing the voice of the report and information capable of identifying the report source terminal device 20-1. The report source specifying unit 12 may store, in the storage unit 17, the emergency report 172 including a sentence representing the report voice, which is recognized using an existing voice recognition technology, for example. The report source specifying unit 12 specifies the report source terminal device 20-1 by extracting information capable of identifying the report source terminal device 20-1 included in the emergency report 172.

[0024] The notification recipient identification unit 13 identifies a notification recipient terminal device 20-2 from among the multiple terminal devices 20 whose proximity to the reporting terminal device 20-1, indicated by the location information 171, satisfies the notification recipient identification criterion 173. The notification recipient identification criterion 173 indicates, for example, that the distance from the reporting terminal device 20-1 is below a predetermined threshold. The notification recipient identification criterion 173 is provided, for example, by the user of the emergency notification support device 10. Based on the location information 171, the notification recipient identification unit 13 can calculate the distance between the reporting terminal device 20-1 and the other terminal devices 20.

[0025] The notification recipient identification unit 13 may use different notification recipient identification criteria 173 depending on the severity of the event represented by the emergency call 172. In this case, the notification recipient identification criteria 173 represent criteria for each level of severity of the event represented by the emergency call 172 (e.g., the severity of the patient's condition, the severity of the fire that occurred, etc.). The notification recipient identification unit 13 then identifies the notification recipient terminal device 20-2 by comparing the severity of the event represented by the emergency call 172, obtained by analyzing text representing the emergency call 172, for example, with the notification recipient identification criteria 173. The notification recipient identification unit 13 can determine the severity of the event represented by the emergency call 172 by extracting keywords from the text representing the emergency call 172 that represent, for example, the amount of bleeding and whether the patient is conscious or not, or the extent of the fire that occurred.

[0026] For example, if emergency call 172 is an emergency medical emergency, and the patient indicated by the emergency call has a minor injury, and many people are capable of providing emergency medical treatment to that patient, then it is presumed that there are many people capable of providing such treatment who are near the calling terminal device 20-1. Therefore, in this case, the threshold value for distance from the calling terminal device 20-1 indicated by the notification recipient identification criterion 173 may be small. On the other hand, if the patient indicated by the emergency call has a serious injury, and the people capable of providing emergency medical treatment to that patient are limited to those with advanced skills in emergency medical treatment, then it is presumed that there are few people capable of providing such treatment who are near the calling terminal device 20-1. Therefore, in this case, it is desirable to set a large value for the threshold value for distance from the calling terminal device 20-1 indicated by the notification recipient identification criterion 173 so that emergency call 172 can be notified to people capable of providing such emergency medical treatment. In other words, the threshold value indicated by notification recipient identification criterion 173 should be larger the greater the severity of the emergency patient's symptoms (condition of injury) as expressed in emergency call 172.

[0027] Furthermore, if emergency call 172 is a report of a fire, and the scale of the fire indicated by the report is small, it is presumed that the area requiring evacuation from the fire is small, so the threshold value for the distance to the reporting terminal device 20-1 indicated by the notification recipient identification criterion 173 may be small. On the other hand, if the scale of the fire indicated by the report is large, it is presumed that the area requiring evacuation from the fire is large, so it is desirable that the threshold value for the distance to the reporting terminal device 20-1 indicated by the notification recipient identification criterion 173 be large. In other words, the threshold value indicated by the notification recipient identification criterion 173 should be larger the larger the scale (i.e., severity) of the fire represented by emergency call 172.

[0028] The notification recipient identification unit 13 may also use the notification recipient registration information 174 when identifying the notification recipient terminal device 20-2. The notification recipient registration information 174 is information representing terminal devices 20 that have been previously registered as recipients of emergency calls 172. When the notification recipient identification unit 13 uses the notification recipient registration information 174, it identifies the terminal devices 20 registered in the notification recipient registration information 174 (registered terminal devices) as the notification recipient terminal device 20-2, among the terminal devices 20 that satisfy the notification recipient identification criteria 173 in terms of proximity to the reporting terminal device 20-1. In other words, in this case, even if a terminal device 20 satisfies the notification recipient identification criteria 173 in terms of proximity to the reporting terminal device 20-1, if it is not registered in the notification recipient registration information 174, the notification recipient identification unit 13 excludes it from being identified as the notification recipient terminal device 20-2.

[0029] The notification recipient registration information 174 may also include attributes indicating whether or not the user of the registered terminal device is capable of performing emergency treatment on an emergency patient in the condition indicated by the emergency call 172. Attributes indicating whether or not emergency treatment can be performed include, for example, whether or not artificial respiration can be performed, whether or not cardiac massage can be performed, whether or not hemostasis can be performed, and whether or not emergency treatment can be performed on fracture sites. In this case, the notification recipient identification unit 13 identifies the registered terminal device of a user capable of performing emergency treatment on an emergency patient in the condition indicated by the emergency call 172, as the notification recipient terminal device 20-2, from among the registered terminal devices whose proximity to the reporting terminal device 20-1 satisfies the notification recipient identification criteria 173, as indicated by the notification recipient registration information 174.

[0030] The notification unit 14 notifies the notification destination terminal device 20-2, which has been identified by the notification destination identification unit 13, of the terminal devices 20, of the emergency call 172 and the location information 171 relating to the reporting terminal device 20-1. In other words, the notification unit 14 does not notify the other terminal devices 20-3 included in the terminal device 20 of the emergency call 172 and the location information 171 relating to the reporting terminal device 20-1.

[0031] The notification unit 14 also acquires emergency treatment information 175, which represents the method of emergency treatment for the emergency patient whose condition is indicated by the emergency call 172, from a device (such as a database) that is communicably connected to the emergency call support device 10, and stores it in the storage unit 17. The notification unit 14 also notifies the receiving terminal device 20-2 of the acquired emergency treatment information 175. The emergency treatment information 175 represents the method of emergency treatment, such as how to perform artificial respiration and cardiac massage, and how to use an AED, and may be in the form of text, diagrams, or videos. The notification unit 14 may also choose to notify only the receiving terminal device 20-2 that has responded to the emergency call 172 indicating that it will go to the scene, of the emergency treatment information 175.

[0032] The input / output unit 15 outputs the emergency call 172 acquired by the acquisition unit 11 to the management terminal device 30. The management terminal device 30 presents the emergency call 172 to the user of the emergency call support device 10 by displaying the text represented by the emergency call 172 output from the input / output unit 15 on a display screen equipped with the text, or by outputting the sound represented by the emergency call 172 from a speaker equipped with the sound. The user of the emergency call support device 10, upon being presented with the emergency call 172, determines, for example, whether the emergency call 172 is a false alarm such as a prank call, based on the content and sound quality of the emergency call 172.

[0033] The input / output unit 15 receives instruction information, input by the user of the emergency call support device 10 via the management terminal device 30 in response to the presented emergency call 172, which instructs whether or not to notify the destination terminal device 20-2 of the emergency call 172 and the location information 171 related to the calling terminal device 20-1 by the notification unit 14. The instruction information indicates that if the user determines that the emergency call 172 is not a false alarm, the notification unit 14 will not notify the destination terminal device 20-2. The instruction information indicates that if the user determines that the emergency call 172 is a false alarm, the notification unit 14 will not notify the destination terminal device 20-2.

[0034] If the instruction information indicates that a notification should be sent to the notification destination terminal device 20-2, the notification unit 14 will send the notification; if the instruction information indicates that no notification should be sent, the notification unit 14 will stop sending the notification.

[0035] The determination unit 16 extracts characteristics from the emergency call 172 that are necessary to determine whether the emergency call 172 is a false alarm, such as a prank call. These characteristics include, for example, whether the emergency call 172 contains logically contradictory content. These characteristics include, for example, characteristics related to the tone of the voice shown in the emergency call 172.

[0036] The determination unit 16 determines whether the characteristics extracted from the emergency call 172 satisfy the false alarm determination criteria 176, and if the characteristics satisfy the false alarm determination criteria 176, it determines that the emergency call 172 is a false alarm. The false alarm determination criteria 176 are criteria for determining whether a speech contains lies, based on the content and tone of the speech, etc., from the standpoint of psychology, for example. The false alarm determination criteria 176 may be provided by the user of the emergency call support device 10, or may be obtained from a device that is communicatively connected to the emergency call support device 10. Alternatively, the false alarm determination criteria 176 may be criteria generated or updated by learning the relationship between the characteristics of the content and tone of emergency calls 172 obtained in the past and the fact that the emergency call 172 was a false alarm such as a prank, using machine learning technology.

[0037] If the determination unit 16 determines that the emergency call 172 is a false alarm, the notification unit 14 stops notifying the recipient terminal device 20-2 of the emergency call 172 and the location information 171 related to the calling terminal device 20-1.

[0038] The acquisition unit 11 acquires information to identify the personnel terminal device 40 carried by personnel (ambulance crew, firefighters, police officers, etc.) dispatched to the scene in response to the acquired emergency call 172, for example, from a device that is communicably connected to the emergency call support device 10. The notification unit 14 then notifies the calling terminal device 20-1 and the receiving terminal device 20-2 of information that identifies the personnel terminal device 40 (for example, a telephone number). The notification unit 14 also notifies the personnel terminal device 40 of information that identifies the calling terminal device 20-1 and the receiving terminal device 20-2 (for example, a telephone number).

[0039] Next, with reference to the flowchart in Figure 2, the operation (processing) of the emergency notification support device 10 according to this embodiment will be described in detail.

[0040] The acquisition unit 11 acquires location information 171 of multiple terminal devices 20 at any time or at predetermined timings (step S101). The call source identification unit 12 acquires an emergency call 172 from one of the terminal devices 20, which is the call source terminal device 20-1 (step S102). The determination unit 16 extracts from the emergency call 172 whether there are any logical inconsistencies in its content and characteristics such as the tone of the voice represented by the emergency call 172, and determines whether those characteristics satisfy the false alarm determination criteria 176 (step S103).

[0041] If the characteristics extracted by the determination unit 16 satisfy the false alarm determination criteria 176 (Yes in step S104), the determination unit 16 determines that the emergency call 172 is a false alarm, and the entire process ends. If the characteristics extracted by the determination unit 16 do not satisfy the false alarm determination criteria 176 (No in step S104), the call source identification unit 12 identifies the call source terminal device 20-1 that made the emergency call 172 from among the terminal devices 20, and the notification unit 14 obtains emergency treatment information 175 that represents the method of emergency treatment for the emergency patient whose condition is indicated by the emergency call 172 (step S105).

[0042] The notification recipient identification unit 13 identifies the terminal device 20 as the notification recipient terminal device 20-2, which is located close to the reporting terminal device 20-1, satisfies the notification recipient identification criteria 173, and whose user is registered in the notification recipient registration information 174 as being capable of performing emergency treatment on an emergency patient in the condition indicated by the emergency call 172 (step S106).

[0043] The notification unit 14 notifies the receiving terminal device 20-2 of the emergency call 172, location information 171 related to the calling terminal device 20-1, and first aid information 175 (step S107). The notification unit 14 notifies the calling terminal device 20-1 and the receiving terminal device 20-2 of information that identifies the team member terminal device 40 acquired by the acquisition unit 11, and notifies the team member terminal device 40 of information that identifies the calling terminal device 20-1 and the receiving terminal device 20-2 (step S108), and the entire process is completed.

[0044] The emergency call support device 10 according to this embodiment can help a person near the scene where an emergency call was made to quickly recognize the event indicated by the emergency call. This is because the emergency call support device 10 notifies a recipient terminal device 20-2 of the emergency call 172 and the location information 171 related to the call source terminal device 20-1, which is close enough to the recipient identification criteria 173 as indicated by the location information 171.

[0045] The effects realized by the emergency notification support device 10 according to this embodiment will be described in detail below.

[0046] For example, if an emergency call is made to report a medical emergency, if a person familiar with emergency medical procedures who is near the scene of the emergency call is aware that an emergency call has been made, they can provide more appropriate support for the emergency medical treatment of the patient. Similarly, if an emergency call is made to report a fire, if a person near the scene of the emergency call is aware that an emergency call has been made, residents living near the scene can more appropriately carry out firefighting activities or evacuation actions. In other words, when an emergency call is made, the challenge is to support people near the scene of the emergency call so that they can quickly recognize the event indicated by the emergency call.

[0047] To address these challenges, the emergency call support device 10 according to this embodiment acquires location information 171 from multiple terminal devices 20, acquires an emergency call 172 made from any of the terminal devices 20, and identifies the originating terminal device 20-1 that made the emergency call 172. The emergency call support device 10 identifies a destination terminal device 20-2 from among the terminal devices 20 excluding the originating terminal device 20-1, whose proximity to the originating terminal device 20-1, as indicated by the location information 171, satisfies the destination identification criteria 173. The emergency call support device 10 then notifies the destination terminal device 20-2 of the emergency call 172 and the location information 171 related to the originating terminal device 20-1. As a result, when an emergency call is made, the emergency call support device 10 can help people near the scene where the emergency call was made to quickly recognize the event indicated by the emergency call.

[0048] Furthermore, the emergency call support device 10 according to this embodiment identifies a notification destination terminal device 20-2 from among the registered terminal devices registered in the notification destination registration information 174. The notification destination registration information 174 includes attributes relating to the user of the registered terminal device indicating whether or not emergency treatment can be performed on an emergency patient in the condition indicated by the emergency call 172. The emergency call support device 10 identifies the registered terminal device of a user who can perform the emergency treatment indicated by the notification destination registration information 174 as the notification destination terminal device 20-2. In other words, the emergency call support device 10 only notifies emergency call 172 to people who are expected to be able to perform emergency treatment on an emergency patient in the condition indicated by the emergency call 172, thereby reducing dissatisfaction for people who find the emergency call 172 notification bothersome.

[0049] Furthermore, the notification recipient identification criterion 173 according to this embodiment indicates that the distance from the reporting terminal device 20-1 is below a threshold, and this threshold is larger the greater the severity of the event represented by the emergency call 172 (for example, the severity of the emergency patient's condition, or the scale of the fire). In other words, the emergency call support device 10 can more reliably request assistance for emergency treatment from people who are capable of providing emergency treatment (i.e., those with advanced skills in emergency treatment), which decreases as the emergency patient's condition represented by the emergency call 172 becomes more serious. Also, the emergency call support device 10 can request assistance for firefighting activities or instruct people to evacuate from the fire from a wider range of people as the scale of the fire represented by the emergency call 172 becomes larger.

[0050] Furthermore, the emergency call support device 10 according to this embodiment acquires emergency treatment information 175, which represents the method of emergency treatment for the emergency patient whose condition is indicated by the emergency call 172, and notifies the notification terminal device 20-2 of the emergency treatment information 175. This enables the emergency call support device 10 to provide more appropriate support for emergency treatment by the user of the notification terminal device 20-2 at the scene.

[0051] Furthermore, the emergency call support device 10 according to this embodiment outputs an emergency call 172 and receives instruction information, input by fire department or police station personnel, etc., in response to the outputted emergency call, which instructs whether or not to notify the notification destination terminal device 20-2 of the emergency call 172 and location information 171 relating to the calling terminal device 20-1. If the instruction information indicates that the notification should not be made, the emergency call support device 10 stops making the notification. In this way, the emergency call support device 10 can avoid notifying the notification destination terminal device 20-2 of an emergency call 172 that is a prank or other false alarm, etc., according to the judgment of fire department or police station personnel, etc.

[0052] Furthermore, the emergency call support device 10 according to this embodiment extracts characteristics from the emergency call 172, and if the extracted characteristics satisfy the false alarm determination criteria 176, it determines that the emergency call 172 is a false alarm. If it determines that the emergency call 172 is a false alarm, it stops notifying the emergency call 172. In other words, since the emergency call support device 10 automatically determines whether or not the emergency call 172 is a false alarm, it can reduce the burden on fire department or police station personnel.

[0053] Furthermore, the emergency call support device 10 according to this embodiment acquires information that identifies the team member terminal device 40 carried by the team member dispatched in response to the emergency call 172. The emergency call support device 10 then notifies the call source terminal device 20-1 and the notification destination terminal device 20-2 of the information that identifies the team member terminal device 40, and notifies the team member terminal device 40 of the information that identifies the call source terminal device 20-1 and the notification destination terminal device 20-2. As a result, the emergency call support device 10 enables people at the scene and the team member to communicate with each other until the team member arrives at the scene, thereby enabling more appropriate emergency treatment to be provided at the scene.

[0054] Furthermore, the emergency notification support device 10 according to this embodiment may identify the notification destination terminal device 20-2 in a manner different from that described above. For example, the notification destination identification unit 13 may identify the notification destination terminal device 20-2 from among terminal devices 20 that communicate with a first base station that communicates with the notification source terminal device 20-1, and terminal devices 20 that communicate with a second base station whose proximity to the first base station meets a criterion (for example, is below a threshold). Alternatively, the emergency notification support device 10 may identify the notification destination terminal device 20-2 by utilizing an existing system (mechanism) that controls the sending of emergency alert emails that notify terminal devices 20 of the disaster situation to people in the affected area, for example, in the event of a disaster.

[0055] Furthermore, the emergency call support device 10 may be implemented not by an information processing device such as a server, but by an application run on, for example, a smartphone which is the calling source terminal device 20-1. In this case, the calling source identification unit 12 identifies itself as the calling source terminal device 20-1 when an emergency call 172 is made from its own device. The acquisition unit 11 identifies, for example, as described above, a terminal device 20 that communicates with a first base station with which its own device is communicating, and a terminal device 20 that communicates with a second base station whose proximity to the first base station meets the criteria, as the notification destination terminal device 20-2. The notification unit 14 then notifies the notification destination terminal device 20-2 of the emergency call 172 and location information 171 about its own device, for example, via a system that controls the sending of emergency alert emails that are limited to a target area.

[0056] <Second Embodiment> Figure 3 is a block diagram showing the configuration of an emergency notification support device 50 according to a second embodiment of the present invention.

[0057] The emergency call support device 50 according to this embodiment includes an acquisition unit 51, a call source identification unit 52, a notification destination identification unit 53, and a notification unit 54. The acquisition unit 51, call source identification unit 52, notification destination identification unit 53, and notification unit 54 are examples of acquisition means, call source identification means, notification destination identification means, and notification means, respectively.

[0058] The acquisition unit 51 acquires location information 510 of multiple terminal devices 60. The terminal devices 60 are, for example, devices similar to the terminal device 20 in the first embodiment. The location information 510 is, for example, information similar to the location information 171 in the first embodiment. The acquisition unit 51 operates, for example, similarly to the acquisition unit 11 in the first embodiment.

[0059] The reporting source identification unit 52 acquires the emergency call 520 made from one of the terminal devices 60 and identifies the reporting source terminal device 60-1 that made the emergency call 520. The emergency call 520 is, for example, a call similar to the emergency call 172 in the first embodiment. The reporting source terminal device 60-1 is, for example, a terminal device similar to the reporting source terminal device 20-1 in the first embodiment. The reporting source identification unit 52 operates, for example, in the same way as the reporting source identification unit 12 in the first embodiment.

[0060] The notification recipient identification unit 53 identifies a notification recipient terminal device 60-2 from among the terminal devices 60, excluding the reporting source terminal device 60-1, whose proximity to the reporting source terminal device 60-1, as indicated by the location information 510, satisfies the notification recipient identification criteria 530. The notification recipient identification criteria 530 is, for example, a criterion similar to the notification recipient identification criteria 173 in the first embodiment. The notification recipient terminal device 60-2 is, for example, a terminal device similar to the notification recipient terminal device 20-2 in the first embodiment. The notification recipient identification unit 53 operates, for example, in the same manner as the notification recipient identification unit 13 in the first embodiment.

[0061] The notification unit 54 notifies the receiving terminal device 60-2 of the emergency call 520 and location information 510 related to the calling terminal device 60-1. The notification unit 54 operates, for example, in the same manner as the notification unit 14 in the first embodiment.

[0062] Next, with reference to the flowchart in Figure 4, the operation (processing) of the emergency notification support device 50 according to this embodiment will be described in detail.

[0063] The acquisition unit 51 acquires location information 510 of multiple terminal devices 60 (step S201). The call source identification unit 52 acquires the emergency call 520 made from one of the terminal devices 60 and identifies the call source terminal device 60-1 that made the emergency call 520 (step S202).

[0064] The notification recipient identification unit 53 identifies a notification recipient terminal device 60-2 from among the terminal devices 60 excluding the reporting terminal device 60-1, whose proximity to the reporting terminal device 60-1, as indicated by the location information 510, satisfies the notification recipient identification criteria 530 (step S203). The notification unit 54 notifies the notification recipient terminal device 60-2 of the emergency call 520 and the location information 510 related to the reporting terminal device 60-1 (step S204), and the entire process is completed.

[0065] The emergency call support device 50 according to this embodiment can help a person near the scene where an emergency call was made to quickly recognize the event indicated by the emergency call. This is because the emergency call support device 50 notifies a recipient terminal device 60-2 of the emergency call 520 and the location information 510 related to the call source terminal device 60-1, which is close to the call source terminal device 60-1 indicated by the location information 510 and satisfies the notification recipient identification criteria 530.
