[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic switching system that manages a prepaid toll system, and more particularly to an electronic switching system that notifies callers by voice that their toll is about to run out.

0002

[Prior Art] Conventionally, an electronic exchange device that manages a prepayment method of tolls is used when a toll is input into an external toll input device installed near a caller's telephone. A connected host computer calculates the remaining charges associated with the charged call. When the host computer notifies in advance that the remaining charge is close to 0, a warning notification is given to the caller with an alarm sound. When the remaining charge reached zero, the call was forcibly disconnected.

0003

[Problem to be Solved by the Invention] However, since the above-mentioned conventional warning notification for forced call disconnection is performed with an alarm sound,
This caused discomfort to the caller, and furthermore, detailed information about the cause of the warning was unclear. There is also a problem in that the call is forcibly disconnected without any warning sound for the recipient.

The present invention solves these conventional problems by eliminating the discomfort caused by warning sounds and by adding detailed information on the cause of the warning to both the sender and the recipient. It is an object of the present invention to provide an electronic switching device that gives audible warning notification of forced call disconnection.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a communication path connecting a caller and a receiver's telephone, an external charge input device into which a charge is input, and an external charge input device into which a charge is input. A host computer calculates the remaining charge associated with a call, and when the host computer notifies in advance that the remaining charge approaches 0, a voice synthesizer is connected to the call path, and the remaining charge becomes 0. a central control device that causes the call path to forcefully disconnect the call when notified of this, and the voice synthesizer that sends an audio warning notification to both parties of the forced call disconnection due to charge expiration when connected to the call path. It is equipped with a device.

[0006]

[Operation] According to the present invention, the host computer calculates the remaining charge associated with the call for which the charge was input into the external charge input device, and notifies the central control unit that the remaining charge approaches 0. Then, a voice synthesizer is connected to the communication path and issues an audio warning to both parties on the call that the call will be forcibly disconnected due to the charge being expired. Then, when the remaining charge becomes 0, the call path is forcibly disconnected.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. The extension telephone 1 is controlled by an extension control device 2 . The extension line control device 2 is connected to a communication path 3, and this communication path 3 is connected to an external line control device 8 that controls an outside line. The communication path 3 and the extension control device 2 are controlled by a central control device 4. Further, an external charge input device 6 into which call charges are inputted is connected to the host computer 5, and the remaining charge associated with the call for which the charge has been input is calculated and managed. Furthermore, the voice synthesizer 7 can be connected to the communication path via the central control device 4, and can issue a warning notification to both parties via voice that the call will be forcibly disconnected. . The broken line in the figure indicates an electronic exchange, and this electronic exchange is equipped with the external charge input device and a host computer as external devices to form an electronic exchange device.

The operation of this embodiment will be explained below. When the call charge is input into the external charge input device 6, the external charge input device 6 transmits the individual identification number of the telephone 1 and the input charge to the host computer 5. The host computer 5 calculates and manages fees by storing these information. Next, when the caller goes on-hook with telephone 1, the central control unit determines whether or not the call is possible based on this charge.
Inquiry is made to the host computer 5 if the request is not accepted. If the call is possible, the central control device 4 secures the call path 3. This completes the call. During the call, the host computer 5 calculates the remaining charge. When the central processing unit 4 is notified in advance by the host computer 5 that the remaining charge is approaching 0, it connects the speech synthesizer 7 to the communication path 3. Through this connection, the voice synthesizer 7 sends a warning notification that the call will be forcibly disconnected due to the charge expiration, by voice.
This is done for both parties on the call. When the central controller 4 is notified that the call continues and the call charge has actually become 0, the central controller 4 commands the call path 3 to forcibly disconnect the call.

[0009] Most importantly, the caller can extend the call again by immediately making an additional charge due to the warning notification, and the warning notification is issued again when the remaining amount of the additional charge approaches 0. Of course it is also possible. Further, in the above embodiments, it has been explained that the sender pays the fee, but in other embodiments, it is also possible to allow the receiver to pay the fee.

0010

[Effects of the Invention] As explained above, according to the electronic exchange device of the present invention which provides an audio warning notification of a forced call disconnection, an audio warning notification of a forced call disconnection due to a charge expiry is sent to both parties on the call. Therefore, there is no need to use a warning sound as in the conventional case, and the discomfort caused by the warning sound can be eliminated. Furthermore, by using voice, it is possible to notify both parties on the call with detailed information about the cause of the warning, ie, information such as that the charge has expired.
