PURPOSE:To immediately annouce a call tariff without fail by detecting the end of a call on the side of an exchange when the end of the call is announced while holding a line after the end of the call, calculating the call tariff, and announcing the calculated call tariff by connecting an announcing device to the held line. CONSTITUTION:This system is equipped with a telephone set 20, exchange 21 housing the telephone set 20, and exchange 22 equipped with a tariff announcing mechanism, and the exchange 22 is equipped with a network (NW) 23, central control equipment 24, memory 25 and announce device 26 or a multi- frequency signal device 27. When the call is completed, the call originating telephone set 20 transmits a call end announce signal in the state of holding the line and when the call end announce signal is received, the exchange 21 calculates the call tariff and announces the calculated call tariff from the announce device to the call originating telephone set 20 by connecting the announce device to the held line. Thus, the call tariff is immediately announced without fail, and the reliability of announcement is improved.

Description

[Detailed description of the invention] [overview] Concerning the instant notification method for telephone charges.

The purpose of this system is to provide an instant notification method for telephone charges that allows you to receive a charge notification after a call ends without having to call back the calling telephone from the exchange. The call rate calculation means of the exchange is activated, and when one call ends, the calling telephone sends a call termination notification signal by the call termination notification means while the line is on hold, and when the exchange receives the termination notification signal by the call termination notification detection means, the call is terminated. Calculate the charge and connect a notification device to the put on hold line.

The notification device is configured to notify the calling telephone of the calculated call charge.

[Industrial application fields] The present invention relates to an instant notification system for telephone charges.

When calling domestically or internationally, you may want to know the telephone charge after 9 calls are completed. There are methods that have been used for this purpose, but they cannot always provide reliable notification, so improvements are desired.

[Conventional technology] FIG. 5 is an explanatory diagram of a conventional example.

As a conventional method for notifying telephone charges from an exchange (telephone office) after a call ends, there are nine methods (1) and (2).

■This method is shown in the explanatory diagram of the conventional example in FIG.
'r! L call users must enter the access code (in this example, “002
”) in front of the other party's number and dial. The other party answers and the call is made.

Once the call is completed, it goes on-hook.

Thereafter, as shown in FIG. 5B, the telephone office (switchboard) side calls the telephone back, and when the user answers, a 9-call charge will be notified.

■Although this method is not shown, the user applies in advance to the operator of the telephone office to request the fee notification service. After completing the next two calls, I go on-hook again. Thereafter, the operator at the central office calls back and notifies the caller of the call charges.

[Problems to be Solved by the Invention] In the conventional methods (■) and (■) described above, when a user who applied to receive notification of the charge for a single call receives a call back from the telephone after the call ends, while waiting for a call back from the central office, When you receive a call from someone else or someone else makes a call using your phone,
Even if you try to notify the charge by calling back from the telephone office, the telephone is canceled because the telephone is busy, or you are left waiting for another try.

If the call is canceled, you will not be able to know the call charges.
There was a problem in that 9 notification was delayed when waiting for retry.

This invention applies to cases where you have applied for notification of call charges in advance.

To provide an instant notification method for call charges that can reliably receive charge notifications after the end of a call.

[Means to solve the problem] FIG. 1 is a diagram showing the principle configuration of the present invention.

In FIG. 1, 1 is a telephone, 10 is a call end notification means, 1
1 is a display means, 2 is an exchange, 3 is a network, 4 is a control device, 5 is a call charge calculation means 6 is a call end notification detection means,
7 is a notification device.

The exchange 2 is a central office exchange equipped with a call charge calculation function and a notification function, and may be a different exchange (such as a higher order exchange) from the exchange that accommodates the TIT call center.

In the present invention, when the end of the call is notified while the line is on hold after the call ends, the exchange detects the end of the call, calculates the call charge, and connects the voice or MF multiplier signal notification device to the line where the call was put on hold. This is to notify you of the charges.

[Operation] If the user of the telephone 1 desires to be notified of charges, he or she dials the number requesting the call charge notification service in the same manner as in the past. Control device 4 of exchange llI2 that received this
5 stores information necessary for notification of call charges, and when connection with the other party's telephone is established under the control of the control device 4 and the other party starts responding, 9 stores the call start time. Thereafter, when the 9 calls are completed, the user operates the call end notification means 10 of the telephone 1.

Put the line on hold (do not go on-hook).

The notification signal generated by the call termination notification means 10 is detected by the call termination notification detection means 6 of the exchange 2.

This time corresponds to the end time of the call, and the output of the call end notification detection means 6 is given to the control device 4. When the control device 4 supplies the information necessary for the charge calculation to the one-call charge calculation means 5, the calculation is immediately performed. The result of this calculation is sent to the 1 notification device 7, and the control device 4 controls the connection of the 9 notification device 7 to the line of the telephone 1 which is on hold.

When the telephone 1 is connected to the notification device 7, the notification device 9 notifies the user of the call charge. The notification device 7 can use a signaling device such as a voice announcement device or a multi-frequency signal (same as PB double signal for dialing) ordering device, and the telephone 1 allows the user to hear a voice notification of call charges from the receiver. can. Further, if the telephone 1 is provided with a multi-frequency signal receiving means (not shown) and a display means 11, the notification by the multi-frequency signal can be recognized by looking at the contents displayed on the display means 11.

In this way, after the phone user ends a call, the user is notified of the end of the call and keeps the line on hold without going on-hook, so incoming calls from other parties will not be accepted after the call is ended, so the call charge will be reduced reliably. instant notification will be realized.

[Embodiment] FIG. 2 is a system configuration diagram of an embodiment of the present invention, and FIG. 3 is an explanatory diagram of the operating state.

In FIG. 2, 20 is a telephone l1l (corresponding to 1 in FIG. 1), and 21 is an exchange in which the telephone 20 is housed.

22 is an exchange with a charge notification mechanism (corresponds to 2 in Figure 1)
It is.

The exchange 22 includes a network (NW) 23°, a central control unit 24. Memory 25. An announcement device 26 or a multi-frequency signal device 27 is provided.

The telephone set 20 can be an ordinary telephone set, and a call termination notification signal sent to the exchange when the call ends is 1, for example, ``1''.
Hunking J + r9. ``Funking J+r#J
(or "*") is used.

Alternatively, it is also possible to provide the filling machine with a push button that generates a special end-of-call notification signal.

The operation of the embodiment shown in FIG. 2 will be explained with reference to the operating state diagram shown in FIG.

As shown at A in FIG. 3, the calling telephone 20 dials the telephone number of the other party with an access code "002" requesting post-call charge notification service added to the beginning, as in the conventional example.

When the exchange 21 receives this dial, it analyzes the dial and identifies that post-call charge notification service is requested, and also captures the line of the upper exchange 22 for connecting to the other party's telephone and dials the number. Send information.

In response to this, the exchange 22 identifies that the call requests instant call charge service, stores the information necessary for charge calculation in the memory 25 (Fig. 2), and connects the other party. The central control unit 24 (second
(Figure).

At this time, one originating subscriber number is required as information necessary for performing fee calculation and notification service.

This information is obtained by requesting exchange 8122 to exchange 21.

A call path is formed from the exchange 22 to the called subscriber. 1 When the called subscriber answers the call, the exchange 22 detects this and records the call start time in the memory 25. 0 When the call starts, the calls on this line are The operation of monitoring the signal is started.

When one calling subscriber ends a call, as shown in B in Fig. 3, the end of call is notified by sequentially pressing the "Hooking" and "9" keys on the filling machine 20, and the call goes on-hook. Don't wait.

The exchange@22 detects this notification signal on one line by the above-mentioned monitoring operation and identifies it as a call termination notification. As a result, the central control unit 24 records the end time of the call in the memory 25, disconnects the connection between the terminal on the calling subscriber side and the terminal on the called subscriber side of the network 23, and disconnects the terminal on the calling subscriber side of the network 23. The terminal and the announcement device 26 are connected.

On the other hand, the central control device 24 calculates the call fee based on the call information stored in the memory 25 and supplies the calculation result data to the announcement device 26.

As a result, the announcement device 26 generates a voice corresponding to the input data, and the calling subscriber 9 can learn the call charge through the voice from the telephone 20.

C1 in FIG. 3 shows a state in which calculation data is sent out from the multi-frequency signal device 27. In this case, talk about it! The multi-frequency signal is received at 20 and displayed on a display device such as a liquid crystal display.

FIG. 4 shows charge data based on multi-frequency signals and an example of its display. In this case, simply as shown in Figure 2.

Not only to inform you of the charges, but also as relevant information.

The other party's number (receiving subscriber number) 1 call start time 9 call duration are also notified.

As another example, a facsimile machine with a display can also be used as a filling machine terminal, and it is similar to a normal telephone until connection with the other party, and after the facsimile transmission is completed, one call is terminated and a charge notification service is requested. Sending out signals (
When the subscriber performs hooking and key operation 9 in the same way as described above, the exchange 22 notifies the subscriber's facsimile machine of the call charge in the signal format used by the facsimile machine instead of the multi-frequency signal. This can be displayed on the display of the facsimile machine.

Further, as another modification, when one calling subscriber makes a call, the call may be made without adding an access code requesting the charge notification service, and after the second call is completed, a call termination and charge notification request signal may be sent. In this case, as a transmission signal from the exchange 21 to the exchange 8122, it is necessary to transmit not only the one-call end signal but also a signal requesting a charge notification.

[Effects of the Invention] According to the present invention, there is no need to call back as in the past for charge notifications, which increases immediacy and prevents incoming calls from other people to the phone being used or from the phone being used by other people. Since a busy state does not occur due to the call, the fee notification is reliably executed and the credibility of the notification is improved.
