Abstract

PURPOSE:To enable a call charge to be informed to a caller by a telephone set used for the call by informing acoustically the call charge to the caller by the indication of the caller when a call is finished in a telephone exchange. CONSTITUTION:A central controller 8 starts the calculation of charging and transmits a call charge to a storage device 9 at each unit time. When the caller hooks on once a handset for the end of the call, the central controller 8 detects it via a scanner 6, stops charging and also stops the transfer of charge to the storage device 9. When the caller A1 hooks off again the handset after a prescribed time, the central controller 8 detects it via the scanner 6, the charging for the finished call's share just now of the caller A1 is read from the storage device, converted into voice at a voice synthesis output device 5 and the voice is informed to the caller A1 via a channel switch 2.

Description

[Detailed Description of the Invention] Conventionally, methods for informing the caller of the call charge after the end of the call include a call charge display meter (digital type) that is installed directly on the telephone or as an attached equipment, There are display meters (analog type), but all of these are visual indicators, so the caller needs to find the display and read it, and sometimes people with visual impairments can't see it. , cannot be informed in this way. In addition, such a display device is required in addition to the telephone set, and call charge information that is different from voice information is sent from the switchboard to the display device.The caller can immediately after the call ends to collect the call charge information from the handset used for the call. Despite being a medium for communication, providing telephone exchanges with services that can be known audibly1, call charges, which are notified to the caller at the end of a call, are communicated visually. Therefore, by informing the caller of the JIh call charge through the auditory sense, there is no need for a call charge display device separate from the telephone, and the caller can easily The through port is the system component of the embodiment for calls within one's own office, which has the voice call charge reporting service according to the present invention.

When the caller A1 picks up the handset, the central control device 8 detects the power via the scanning device R6 and sends a dial tone from the call register 6 via the signal distribution device 7 to the caller A1.

When the called party number is dialed by the calling party A1, the central control unit 8 receives it at the calling register 3 via the scanning device 6, analyzes this dialed number, and routes the calling party A1 to the call path. Switch 2, local trunk 4, call path switch 2
The called party B1 is connected to the called party B1 via the telephone.

When the called party B1 responds, the call starts, and the central controller 8 starts billing calculations and transmits the call charges to the storage device 9 for each unit of time. Once the caller hangs up to end the call, the central controller t8 detects this via the scanning device 6, stops charging, and then sends an instruction to stop the charge transfer to the storage device 9. 0 When the caller A1 picks up the receiver again after a certain period of time, the central control unit 8 detects this via the scanning device 6, and records the call number of the caller A1 that has just ended from the memory device f*9. The call charge is read out, converted into voice by the speech synthesis output device 5, and notified to the caller A1 via the call path switch 2.After the call is over, the call charge is notified to the caller A1 by voice.
The caller can receive a new type of service in which the caller can easily know the charge even after the call has ended. For people who are sometimes visually impaired, services that allow them to know prices, which was not possible with conventional price display devices, are very effective. What's more, there is no need for this charge display device, and you can receive this charge notification service using a conventional telephone as is.
