Abstract

PURPOSE:To automatically display telephone number information of a caller on an attendant board by extracting telephone number information of the caller in an originating station at the time of the occurrence of an emergency call and sending this information to an emergency service center with a signal line. CONSTITUTION:The central processing unit on the originating station side discriminates a call to the emergency service center by dial information of the caller and discriminates whether the originating subscriber is stored in its own exchange or not. If it is stored there, its telephone number is extracted; but otherwise, a preceding exchange is requested to send the caller number and the emergency service center side is started and caller number information, the number of the line of contact used at present, and connection control information of the call classification or the like are sent to the emergency service center through the signal line like a data link. In the emergency service center, these caller number information and connection control information are received and are displayed on the display part of the attendant board.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emergency service connection system used for emergency calls from telephone subscribers to fire departments, police departments, etc.

[Conventional technology]

In the conventional emergency service connection method, when an emergency such as a fire or crime occurs, the finder dials a predetermined special number from a nearby telephone.
The central control unit of the originating station where the telephone is housed.

The person handling the reception desk then speaks with the caller and confirms necessary information such as address, name, and telephone number. [Problems to be Solved by the Invention] As mentioned above, in the conventional emergency service connection system, the operator at the reception desk cannot contact the caller until he or she starts talking to the caller through the emergency telephone line. The disadvantage is that you cannot know the phone number.

An object of the present invention is to automatically display the caller's telephone number information on the reception desk at the time of an emergency call, without the operator of the reception desk at the emergency service center asking the caller for confirmation. An object of the present invention is to provide an emergency service connection method in which telephone number information of a caller can be sent in advance from the calling station side.

[Means to solve the problem]

The emergency service connection method of the present invention receives the called information dialed by the calling party, identifies that the called information is a predetermined special number, and identifies the calling party's subscriber number information. and the connection control information of the called station, and sends the subscriber number information and connection control information to the called station corresponding to the called information via a telephone line and another signal line.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a program flowchart showing the processing flow of an embodiment of the present invention.

First, the central processing unit f (not shown) at the calling station identifies from the caller's dialing information that the call is to an emergency service center (step 1). Next, it is determined whether the calling party is a subscriber accommodated in the local exchange (step 2). If the subscriber is accommodated in the own exchange, extract the telephone number (step 3); otherwise, request the preceding exchange to send the calling number; step 4; (Step 5) Next, the emergency service center side is activated via the telephone line (Step 6), and then the calling number information obtained in Step 3 or Step 5 is sent to the emergency service center. The connection control information such as the call line number currently in use and the type of call required for connection control is sent to the emergency service center via a signal line such as a data link (Step 7). By receiving these caller number information and connection control information, the information can be displayed on the display section of the reception console without the operator of the reception desk asking the caller for confirmation.

〔Effect of the invention〕

As explained above, the present invention is configured such that when an emergency call occurs, the calling station extracts the telephone number information of the caller and sends this information to the emergency service center via the signal line. This has the effect that the caller's telephone number information can be automatically displayed on the reception desk without the operator of the reception desk at the service center asking the caller for confirmation.
