Abstract

PURPOSE:To report the charge for a telephone call without giving a special number, by detecting the dialing of the telephone number of a terminating telephone set. CONSTITUTION:When a calling subscriber performs on-hook operation at a subscriber telephone set 1, a channel controller 6 detects the on-hook operation and sends information to a central processor 7. The processor 7 calculates the charge for the telephone call and stores it in the corresponding data area of a subscriber data memory 9. To know the charge for the telephone call, the telephone number of the telephone set 1 is dialed on the telephone set 1. In this case, the telephone number of the calling subscriber is the telephone number of the telephone set 1, so the called subscriber is the calling subscriber and a busy tone is heard. The processor 7 once detecting the busy state of the called subscriber collates the equipment position of the calling subscriber with that of the called subscriber and when the coincidence is detected, the charge data on one up-to- date call is read out of the memory 9 and sent out to a voice informing device 5, which is connected to the calling subscriber to inform the calling subscriber of the charge for the telephone call.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for notifying call charges in a remote telephone exchange.

Traditionally, this type of call charge notification has been carried out by dialing a special number and then dialing the called party's number to notify the call charge after the call ends. In order to add a special number for the telephone, the number of dialed digits received by the exchange increases, requiring a special longevity register and affecting the numbering plan of the telephone network.

An object of the present invention is to provide a call charge notification method that does not require the addition of a special number.

To achieve the above object, the charge notification method according to the present invention is a charge notification method in a storage program control type telephone converter accommodating a subscriber, in which the latest call charge data for one call is stored in the subscriber data memory. The central processing unit that manages telephone exchange operations has a function to store the call charge calculated when the caller ends the call in the area, and a function to store the caller's accommodation location and the receiver when the called party is busy. It has a function to read out the call charge of the subscriber at the accommodation location from the area and notify the calling party by a voice notification device when a match between the accommodation locations is detected. The Vc tank is configured so that the caller is notified of the call charge when the caller dials the telephone number of the telephone from which the caller is making a call.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a block diagram of a telephone exchange constructed according to the method of the present invention. 1 is a subscriber's telephone set, 2 is a communication network, 3 is an outgoing trunk for connection to a subscriber of another station, and 4 is an outgoing register trunk for receiving a dial from a calling party. The voice notification device 5 receives call charge data sent from the central processing unit 7 via the call path control device 6, converts it into voice, and notifies the subscriber. The communication path control device 6 has a function of monitoring the status of the above-mentioned 1 to 5 and sending information to the central processing unit 7, and a function of controlling the above-mentioned 1 to 5 based on the information from the central processing unit 7. The central processing unit 7 performs processing using a main memory 8 and a subscriber data memory 9, performs a connection operation via a communication path control device 6, and further displays a callee accommodation position while a called party is busy and a called party accommodation position. and if they match, the call charge data of the subscriber at the accommodation location is read out from the subscriber data memory 9 and sent to the voice notification device 5 via the call path control device 6, and the call charge data is calculated at the end of the call. It has the function of calculating and storing it in the subscriber data memory of the optical subscriber. The main memory 8 is a memory that temporarily stores programs and information during processing. The subscriber data memory 9 stores the accommodation location, telephone number, and latest charge data for one call for each subscriber.

When a caller makes a call from the subscriber telephone 1 to a subscriber of another station, the central processing unit 7 connects the caller to the subscriber of the other station via the outgoing trunk 3. Note that the connection operation is similar to that of a known exchange, so a detailed explanation will be omitted.

When the caller ends the call, the communication path control device 6 detects the end of the call and sends information to the central processing device 7.

The central processing unit 7 calculates the charge for the call based on the received information and stores it in the corresponding subscriber data area of the subscriber data memory 9.

Here, if the caller knows the call charge, the caller makes a call from the subscriber's telephone 1 and dials the telephone number of the subscriber's telephone 1.

In response to this caller's call, the communication path control device 6 detects the call and sends the call detection information and the caller accommodation location to the central processing unit 7. Based on the information, the central processing unit 7 causes the communication path control unit 6 to connect the caller and the calling register trunk 4. Subsequently, when the caller dials the 'telephone number of the subscriber's telephone set l, the number is received by the outgoing register trunk 4 and sent to the central processing unit 7 via the communication path control unit 6.

The central processing unit 7 stores the subscriber data based on the received number 1c.
The accommodation position of the optical subscriber is read out from the data memory 9, and the state of the accommodation position is determined.

The operation up to this point is normal connection operation, but in this case,
Since the telephone number of the called party is the telephone number of the subscriber telephone set 1, the called party becomes the calling party, and the status of this accommodation position is busy.

When the central processing unit 7 detects that the called party is busy, the central processing unit 7 compares the calling party accommodating position and the called party accommodating position.When it detects that the two accommodating positions match, the central processing unit 7 stores the subscriber data memory 9 according to the accommodating position.
The most recent charge data for one call is read out and sent to the voice notification device 5 via the call path control device 6, and at the same time, the calling party and the voice notification device 5 are connected.

When the voice notification device receives charge data, it converts it into voice based on the data and notifies the caller. If the result of the verification is not a match, that is, if the subscriber is busy when making a call to another subscriber, a busy tone will be returned as in normal connection processing.

As explained in detail above, the present invention is configured to detect that the caller has dialed the telephone number of the telephone used to make the call, thereby making it possible to notify the call charge without assigning a special number. be.
