Abstract

PURPOSE:To automatically and instantly inform the call charge of telephone and data calling at respective calls to a recipient of the service. CONSTITUTION:A terminal 1 connected to an exchange 2 transmits the informing requirement of the call charge to be operation-inputted to the exchange 2 through an ISDN basic interface with the INFO message (a) of a D-channel message after finishing a call. The exchange 2 receives the ISDN basic message (a). At the time of identifying it to be the charge informing requirement at respective calls, the exchange 2 inserts call charge information of the terminal 1 which is already finished accumulation into the INFO message (b) of the D channel message, transmits it to the terminal 1 through the ISDN basic interface 3 and makes the terminal 1 to display call charge information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call charge notification system for notifying a service receiver of call charges for telephone and data calls.

[0002]

2. Description of the Related Art Conventionally, in this type of call charge notification system,
A method in which the call charges of multiple calls made by the service recipient within a certain period are counted for each call, and accumulated and accumulated in the exchange to notify the service recipient collectively. For each call, the recipient of the call asks the exchange to notify the call charge of the call,
After the call, the exchange notifies the service recipient verbally of the call charge of the call.

[0003]

The former of the above-mentioned conventional call charge notifications has a problem that the service recipient cannot notify the call charge of each call immediately after each call. On the other hand, in the latter, there is a problem in that the service recipient is troublesome, and the telephone company has to constantly wait for the operator to do so.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a call charge notification system capable of automatically and immediately notifying the call charge for each call of a telephone call and a data call to the service recipient.

[0005]

[Means for Solving the Problems] Call charge notification method of the present invention
The formula is based on the stored program method for telephone and data calls.
Call charges are counted and accumulated for each service recipient, and
Exchange to notify each service recipient of call charges
In the system, the subscriber terminal connected to the exchange is operated.
A D channel message is sent to request the notification of the input call charges.
The ISDN basic interface through the exchange.
The D channel message is sent to the exchange.
Message and identify that it is a charge notification request for each call
In case of the above, the provision of the services already accumulated
The call charge information of the person in the D channel message
The subscriber end through the ISDN basic interface
Send to the end and display the call charge information on this subscriber terminal
It is a configuration that allows.

[0006]

The present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are message sequence diagrams for explaining the first and second embodiments of the present invention, respectively, and FIG. 3 is a diagram showing a system configuration for explaining the embodiments of the present invention. Is. In FIG. 3, the terminal 1 of the service recipient and the exchange 2 are connected to each other via the ISDN basic interface 3.

In FIG. 2, a message sequence between the terminal 1 of the service recipient and the exchange 2 for explaining the method of notifying the call charge of the call after the call according to the first embodiment of the present invention. It is shown. The exchange 2 counts, accumulates, and accumulates a call charge from the call start to the call end of the terminal 1.

After the end of the call, the terminal 1 requests the exchange 2 for a call charge notification of the call by an INFO message a which is a D channel message.

The exchange 2 is I which is a D channel message.
The NFO message b is used to send the information of the call charge accumulated, counted, and accumulated from the call start to the call end of the terminal 1 to the terminal 1. The terminal 1 displays the received call charge information on the screen.

In FIG. 3, a second embodiment of the present invention, in which a call charge for a call is accumulated during a call, the terminal 1 and the exchange 2 of the service recipient for explaining the method of notifying the call are summed up. The message sequences between each other are shown.
The exchange 2 counts, accumulates, and accumulates a call charge from the call start to the call end of the terminal 1.

Immediately after the start of a call or during a call, the terminal 1 requests the exchange 2 to notify by the INFO message c which is a D channel message each time the call charge of the call is accumulated by the exchange 2.

The exchange 2 collects the call charge information until the end of the call on the terminal 1 by using the INFO message d, which is a D channel message, as the call charge for the call is accumulated.
Send to. Every time the terminal 1 receives the information about the call charge,
Display it on the screen. The same is repeated until the call ends.

[0014]

As described above, according to the present invention, the notification of the call charge of the telephone and the data call made by the service recipient is transmitted by the terminal of the service recipient via the ISDN basic interface by the D channel message. Requesting the call from the exchange, the switch sends out the information of the call charge to the terminal of the service recipient through the ISDN basic interface by the D channel message, and the terminal of the service recipient receives the call charge information. By displaying it on the screen, the call charge for each telephone call and data call made by the service recipient can be automatically and immediately notified to the service recipient. , It may be possible to eliminate the need for the operator to constantly wait to notify the call charge for each telephone and data call made by the service recipient. Kill.

Claims (1)

[Claims] 1. A switching system connected to a switch in a switching system for counting and storing telephone call charges for telephone and data calls for each service recipient by a storage program method, and notifying each of the service recipients of the call charges. The subscriber terminal sends a call charge notification request to be operated by a D channel message to the exchange through the ISDN basic interface, and the switch receives the D channel message and sends a charge notification request for each call. If it is identified, the call charge information of the recipient of the service, which has already been stored, is inserted into the D channel message and transmitted to the subscriber terminal via the ISDN basic interface. A call charge notification system characterized by displaying the call charge information on a terminal.
