Description

  The present invention relates to an emergency communication command system for receiving an emergency notification of an emergency situation, accurately grasping the situation, and establishing a system for promptly responding to the emergency situation. In particular, the emergency notification corresponds to another jurisdiction. The present invention relates to an emergency communication command system that can respond quickly even if it is transferred to the emergency communication command system in the area.

  In a conventional emergency communication command system, a fire fighting line that is an analog dedicated line for fire fighting is used for emergency calls (for example, call 119), and a special trunk for connecting the fire fighting line is accommodated in the line control device. A device that accepts information at a dedicated reception terminal is known.

  This special trunk has a function of holding a line even if the caller performs a disconnection process, and also has a function of calling the caller who has disconnected from the fire department. This function to call is called recall.

  Even if a disconnection signal is received from the calling terminal having a special telephone number, the telephone line between the specific receiving terminal and the exchange is held, and the calling terminal having the special telephone number is received by a recall signal from the specific receiving terminal. Japanese Patent Application Laid-Open No. H10-228707 discloses a holding function when a general line is bypassed for a call or special telephone number call.

Recently, there are cases where a digital line such as ISDN is used instead of an analog dedicated line. Even in this case, even if the caller is disconnected, it is possible to keep the line and perform a call again.
