Description

  The present invention relates to an emergency call system and an emergency call method for reporting an emergency situation such as an elderly person who needs life support.

  2. Description of the Related Art Conventionally, an emergency call system for reporting an emergency such as a crime or a sudden illness to a specific destination is known. FIG. 1 shows an example of a conventional emergency call system. An emergency call system 100 shown in FIG. 1 includes an emergency call device 103 installed in a home 102 of a user 101 such as an elderly person who needs life support, a receiving device 106 installed in an office 105, a center device 107, and A fixed telephone 108 is provided. In the emergency notification system 100, notification data (terminal identification information, notification type, etc.) transmitted from the emergency notification device 103 is temporarily received by the reception device 106 via the telephone network 104. The notification data is transferred to the center device 107 and then switched to a voice call. As a result, the user 101 and the operator 113 can make a voice call using the emergency call device 103 and the fixed telephone 108.

  FIG. 2 shows another example of a conventional emergency call system. In the emergency notification system 110 shown in FIG. 2, when the center device 107 receives the notification data from the emergency notification device 103, the center device 107 transmits an email to the portable terminal device 111 of the helper 109 via the Internet 112, and the user 101 receives the notification data. The helper 109 is notified that an emergency call has been made. The helper 109 who has seen the e-mail makes a phone call to the user 101 so that the user 101 can make a voice call with the helper 109. This makes it possible to respond to an emergency call from the user 101 even when the operator is away from the office 105 such as at night or when going out.

  Hereinafter, the operation of the emergency call system 10 according to the present embodiment will be described with reference to FIGS. 3 to 8.

(1) When the user presses the notification button 40 of the emergency notification device 12 in an emergency, the notification data is transmitted to the reception device 16 via the telephone network 14.

(2) The receiving device 16 receives report data including terminal identification information, report type, and the like.

(3) The receiving device 16 transfers the received report data to the center device 17 via the Internet 22.

(4) Based on the terminal identification information of the notification data, the center device 17 identifies the user 11 who issued an emergency call from a database registered in advance in the user DB unit 63, and a plurality of helpers registered in advance A helper 19 corresponding to the user 11 is determined from 19. Here, it is assumed that a helper 19 in charge is determined for each user 11 in advance, and the helper 19 is determined as a corresponding helper. Further, the center device 17 notifies the voice server 21 of the determined telephone number of the helper 19.

(5) After receiving the notification data to the center device 17, the reception device 16 switches the connection with the emergency notification device 12 to a voice call, puts it on hold, and transfers and connects to the voice server 21.

(6) The voice server 21 calls the portable terminal device 20 of the helper 19 based on the telephone number notified from the center device 17.

(7) When the helper 19 responds to the call, the voice server 21 connects the emergency call device 12 of the user 11 in the hold state and the portable terminal device 20 of the helper 19 so that a voice call can be made.

(8) The helper 19 accesses the center device 17 from the mobile terminal device 20 and refers to the past correspondence status or medical history of the user 11 who is handling, and performs an appropriate report response.

  The operation of the emergency call system 10 according to the present embodiment has been described above. According to the emergency call system 10 according to the present embodiment, when an emergency call is received from the user 11, the helper 19 that is moving outdoors or moving can be quickly called to make a voice call. Thus, the helper 19 can quickly grasp the situation of the user 11 and can take appropriate measures such as a visit and contact with a hospital.

  FIGS. 9A to 9C are diagrams for explaining another method for determining the helper 19 corresponding to the user 11 who has issued the emergency call. In the above embodiment, a helper 19 in charge is determined for each user 11 in advance, and the helper 19 is determined as a corresponding helper. However, when the helper 19 in charge is at a long distance from the user's home 13, it takes time to go to the user's home 13 even if the situation can be grasped by voice call. In an urgent case, it is preferable to request assistance from another helper 19 at a short distance.

  Therefore, in this corresponding helper determination method, the center device 17 uses the helper 19 based on the location information of the helper 19 acquired using the GPS function of the mobile terminal device 20 and the location information of the user home 13 registered in advance. The travel distance necessary to arrive at the user's home 13 is calculated for a plurality of helpers 19. And the helper 19 corresponding to the user 11 is determined based on the calculated moving distance.

  FIG. 9A shows an example of a list of position information for each user stored in the user DB unit 63 of the center device 17 (that is, the address of the user's home 13 where the emergency call device 12 is installed). FIG. 9B shows an example of a list of position information and status information (supported / not supported) for each helper 19 stored in the position information storage unit 67 of the center device 17. It is preferable that the center device 17 periodically obtains and updates the position information and status information from each mobile terminal device 20. FIG. 9 shows a result of calculating the moving distance between the user b home and each helper as an example. The helper determination unit 64 of the center device 17 refers to the calculation result of the moving distance, determines “Helper 3” that can be supported and has the shortest moving distance as the corresponding helper, and sets the telephone number of “Helper 3”. The voice server 21 is notified.

  By adopting such a method, the helper 19 that can reach the user's home 13 with the shortest travel distance can make a voice call with the user 11. Thereby, it becomes possible to perform the life support of the user 11 more rapidly.

  In this method, the movement distance is calculated from the position information using the GPS function of the mobile terminal device 20, but in this case, movement by car or on foot should be assumed. In the case of movement using public transportation such as trains and buses, the required time based on the search result of the transfer guidance service is calculated, and a helper 19 that can reach the user's home 13 with the minimum movement time is provided. Will be determined.

  FIG. 10 is a diagram for explaining still another method for determining a helper corresponding to the user 11 who has issued an emergency call. In this method, the center device 17 notifies the voice server 21 of the telephone numbers of the mobile terminal devices 20 regarding a plurality of helpers 19_1 to 19_n instead of a specific single helper. The voice server 21 calls the portable terminal devices 20_1 to 20_n of the plurality of helpers 19_1 to 19_n all at once, and connects the portable terminal device of the helper that responds first and the emergency call device 12 so that voice communication is possible. At this point, the calling of other helpers is terminated.

  By adopting such a method, it is possible to start a voice call with the helper without causing the user 11 to wait, and the situation of the user 11 can be grasped more quickly. By registering an appropriate number of helpers for each user 11, reporting can be performed more smoothly.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. is there.
