(Step S302), and the special number 40 returns a response to the emergency call device 10 via the GW device (Steps S303 and S304). Subsequently, after the emergency call device 10 receiving the response transmits a message to the special number 40 (step S305), the IP line 30 is disconnected (step S306).

  After that, when a call is returned from the special number 40 to the dedicated telephone 11 via the IP line 30 (steps S307 to S309), an emergency call device is provided as long as there is no incoming call from another general telephone 50 at the timing between line disconnection and call back. 10 can respond to the call back (steps S310 to S312), and the dedicated telephone 11 can communicate with the special number 40 (step S313).

  However, as shown in the processing sequence diagram (2) of FIG. 6, the call from the general telephone 50 is made to the dedicated telephone 11 during the line disconnection (step S406) to the call back (step S410) after the special number notification. Yes (step S407), when the dedicated telephone 11 is called (steps S408 and S409), the IP line 30 is in use, so the emergency call device 10 can respond to the call back from the special number 40 (step S410). Can not. Therefore, mutual communication (step S313) between the dedicated telephone 11 and the telephone of the special number notification receiving organization (special number 40) is not possible.

  The present invention has been made to solve the above-described problem, and even when an emergency call network is constructed using an IP line, it is possible to receive a call back signal from a special number after the line is disconnected. An object of the present invention is to provide an emergency call device and system that enable mutual communication with a telephone.

The telephone I / F unit 103 serves as a connection interface with the dedicated telephone 11 or the main apparatus 12.

(Operation of the embodiment)
Hereinafter, the processing sequence of the emergency call system 100 according to the present embodiment will be described in detail with reference to the processing sequence diagram of FIG. 3. The processing sequence shown in FIGS. 5 and 6 (S301 to S306, respectively) is performed until the caller issues a special number (110) notification from the emergency call device 10 and the IP line 30 is disconnected (steps S101 to S106). , S401 to S406).

  Next, when there is a call from the general telephone 50 between the line disconnection after the special number notification (step S106) and the call back (step S116) (step S107), the GW apparatus 20 sends the call to the emergency call apparatus 10 Instead of the call signal IR, an ID receiving terminal activation signal CAR which is transmitted for 0.5 seconds and ringing for 0.5 seconds is transmitted (step S108: “incoming call (CAR)”), and the emergency call device 10 displays a number display. When a response to the incoming call is obtained (step S109), number display information is transmitted (step S110). And the emergency call apparatus 10 which received number display information cut | disconnects the connection with GW apparatus 20 (step S111).

  When the emergency notification device 10 disconnects the connection with the GW device 20 (step S111), the GW device 20 transmits a call signal IR that is transmitted for 1 second and ringing for 2 seconds to the emergency notification device 10 (step S112). “Incoming (IR)”). In response to this, the emergency call device 10 that has received the number display information determines whether or not the caller telephone number indicated by the number display information is a special number. Therefore, after an automatic response to the call signal IR (step S113), a disconnection request is forcibly issued to the general telephone 50 to the GW apparatus 20 (step S114 "automatic disconnection"). Thus, the GW apparatus 20 that has received the disconnection request forcibly automatically disconnects the line connection with the general telephone 50 (step S115).

  In response to this, the telephone of the special number notification receiving organization (special number 40) transmits a call back signal to the dedicated telephone 11 via the IP line 30, the GW apparatus 20, and the emergency notification apparatus 10 (steps S116, S117, S118). The dedicated telephone 11 that has received the call back signal responds to the telephone (Special Number 40) of the special number notification receiving organization (Steps S119, S120, S121). Then, it becomes possible to make a mutual call using the dedicated telephone 11 of the emergency call device 10 (step S122).

  In addition, according to the emergency call system 100 according to the present embodiment, the emergency call device 10 responds to the incoming call of the number display in the call back state, and automatically receives the incoming call other than the special number 40 notified by the caller number. The configuration for performing the response (step S113) and the automatic disconnection (step S114) has been described. In the case of an automatic response, a message “prompt not to call again because a special number is being reported” is sent to the general telephone 50. Automatic cutting (step S114) may be performed after (step S130). By sending this message, it is possible to avoid the inconvenience that the caller of the general telephone 50 repeats the problem operation immediately after the telephone call is disconnected, and as a result, the call cannot be received from the special number 40.

At this time, the line control unit 101 refers to the previously received number display information (step S110 in FIG. 3), and if the caller number is a special number (step S203 “YES”), the line control unit 101 has received the call back signal. A determination is made (step S204), the dedicated telephone 11 is ringed (step S205), and a mutual call by calling back is enabled (step S206).

  On the other hand, if it is determined in the caller number determination process in step S203 that the call originates from other than the special number 40 (incoming from the general telephone 50) (step S203 “NO”), the line control unit 101 determines that the incoming call is received. In response to this, an automatic response (step S207) and automatic line disconnection are performed (step S208), and the call back signal reception process of step S202 is executed so that the call back from the special number can be received.

  When the emergency call network is constructed using the IP line 30 as described above, the emergency call system 100 according to the present embodiment uses the emergency call device 10 corresponding to the number display, so that the number display is displayed in the call-back state. An automatic response to incoming calls, if the caller ID is other than the special number reported, the incoming call is automatically answered and forcibly disconnected automatically so that the call back signal from the special number 40 can be received. is there.

  In addition, according to the emergency call system 100 according to the present embodiment, only the special number report to the police is illustrated, but not limited to the police, a special number report such as a fire report to the fire department, or an unexpected situation has occurred in a bank or the like.
