Description

  The present invention relates to an emergency call reception system for making a call from a mobile communication telephone to a police (110) or a fire department (119).

  When ordering an incident, accident, or fire from an emergency call reception center such as the police or fire department, the order can be made smoothly if it can be done while observing the situation at the scene. In such a case, as a method conventionally employed, it can be viewed from a picture taken from a helicopter or a camera installed on the roof of a building in the city. However, in general, orders are not made while checking the situation at the site.

  On the other hand, recent mobile phones are the third generation, and those with a videophone function and those with a camera function are standard. On the other hand, the conventional configuration shown in FIG. 6 is a configuration example of a conventional emergency reception system. In FIG. 6, reference numeral 40 is an emergency call reception for the police department (110) and fire department (119), etc. to instruct and contact relevant departments including dispatch commands for patrol cars, fire engines, ambulances, etc. 41 is a report reception device that receives a report from a telephone and switches to the reception stand 43, and 42 is an FPIT (Fire Police Interface Trunk :) that receives an emergency call from the fixed network switch 60 via a dedicated line. Fire fighting / police dedicated line interface trunk), 43 reception desk for receiving emergency calls, 60 a fixed network switch, 61 a fixed telephone, 62 a subscriber circuit connected to the fixed telephone 61 by wire (indicated by LC: line Circuit) ), 63 is an FPT (Fire Police Trunk) for connecting the emergency call of a fixed network switch to the emergency call reception center 40, 64 is fixed A dedicated line (analog) connecting the FPT 63 of the exchange and the FPIT 42 of the emergency call reception center 40, 70 is a mobile network switch, 71 is a mobile communication telephone, 72 is wirelessly communicated with the mobile communication telephone 71, and the mobile network switch A base station 73 connected to 70 is a line for transferring a call of the mobile network switch 70 to the fixed network switch 60.

  In the case of an emergency call from the fixed telephone 61 in FIG. 6, when a user makes a call from the fixed telephone 61, the call arrives at the fixed network switch 60 via the LC 62, and the dial numbers are emergency call numbers (110 and 119). When this is identified, the FPT 63 connected to the emergency call reception center 40 corresponding to the number is captured and connected to the notification reception device 41 via the dedicated line 64 and the FPIT 42. The person in charge of the reception desk 43 of the report reception device 41 responds to the fixed telephone 61 and has a conversation with the caller, so that the accident or incident, the place where the fire has occurred, the situation, the names of the persons concerned, etc. If the situation is ascertained, the department in charge, such as an emergency vehicle, is instructed to dispatch with the information.

  On the other hand, when a user who possesses the mobile communication telephone 71 encounters an accident, an incident or a fire, when the emergency call number is dialed from the mobile communication telephone 71, the base in the area where the mobile communication telephone 71 is located. It is connected to the station 72 by radio, and the mobile network switch 70 via the base station 72 identifies that the calling number from the mobile communication telephone 71 is an emergency call number. Thereafter, there are two conventional connection methods, and the emergency call reception center 40 is connected by any one method.

  One of them is that the mobile network switch 70 is connected to the fixed network switch 60 through the dedicated line 73. In this case, the emergency network number information is sent from the mobile network switch 70 to the fixed network switch 60, and the fixed network switch 60 is connected. The FPT 63 is captured in order to connect to the corresponding emergency call reception center 40 using the exchange 60. Thereafter, the person in charge of the reception desk 43 is connected via the dedicated line 64, the FPIT 42, and the report reception apparatus 41.

  The other is a case where the mobile network switch 70 is provided with a dedicated line 74 directly connected to the emergency call reception center 40. The mobile network switch 70 calls the emergency call number from the mobile communication telephone 71. When this is detected, the dedicated line 74 connected to the corresponding emergency call reception center 40 is captured, connected to the reception board 43 of the notification reception apparatus 41 through the FPIT 42 ', and a call is made with the person in charge of the reception board 43. It is a thing.

  In the relay system of the emergency call system of this conventional example, information to be notified from the mobile communication telephone 71 to the reception desk 43 of the emergency call reception center 40 is often by voice.

  In addition, as a new function in the mobile phone device, a shooting unit that generates an alarm sound and generates a still image or a moving image, a pressure determination unit that detects that an emergency has occurred, or a secret word that indicates an emergency There is known a technique in which a mode switching unit including a secret word determination unit for detecting the above is provided (see Patent Document 1).

In the technique of Patent Document 1, when the occurrence of an emergency is detected by the pressure determination unit or the password determination unit, the mode switching unit switches the mobile phone device to the emergency mode, and outputs an alarm sound when switched to the emergency mode. In addition, the photographing unit is configured to start photographing, generate image data, and transmit emergency contact information including the generated image data to an emergency contact organization such as a police station via the Internet.
