Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an incoming call charge management system in an automatic private branch exchange.

Conventionally, automatic private branch exchanges have adopted a call charge management system in which call charges are managed only for calls made from the extension side to the central office line. Therefore, it has been impossible for the called party to pay the fee even though the call is an incoming call, such as a collect call.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the conventional art, an object of the present invention is to provide an incoming call charge management method in an automatic private branch exchange that can manage call charges for incoming calls from central office lines and also manage collect call charges. be.

In order to achieve the object of the present invention, the configuration of the incoming call charge management system in the automatic private branch exchange according to the present invention is such that in the automatic private branch exchange, incoming calls from the central office line are handled by an extension telephone or a central office line relay stand. means for receiving and recognizing a special number for incoming call charge management instructions and a number indicating the calling area, which the called party enters after hearing the calling area from the calling party when answering; and means for calling an extension telephone after a series of processing related to incoming call charge management is completed when the called party who has confirmed the identification number goes on-hook.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIGS. 1a, b, c, and d are relay system diagrams showing the operating state of an embodiment of the incoming call charge management system in an automatic private branch exchange according to the present invention.

In the figure, 1 is an automatic private branch exchange main body, and 2 is a central office line. 3 is an extension telephone housed in the automatic private branch exchange 1. 4 is a call charge management device of the automatic private branch exchange 1;

As shown in FIG. 1a, when an incoming call is received from the central office line 2 to the automatic private branch exchange main body 1 (indicated by arrow A), the automatic private branch exchange main body 1 calls the extension telephone 3 (indicated by arrow B). Extension telephone 3 responds (indicated by arrow C).

At the time of this response, if the operator of the extension telephone 3 (called party) needs to manage the incoming call charges, he or she first asks the caller's (calling party's) originating area and then checks. Next, as shown in FIG. 1b, the called party dials a special number (indicated by arrow D) indicating incoming call charge management. The automatic private branch exchange main body 1 that received and identified this special number sends a dial tone signal to the extension telephone 3, and the automatic private branch exchange main body 1
to notify that it is ready to receive the calling area code. The following is an example of a dial tone signal sent by the automatic private branch exchange main body 1.

1. The control unit connects the extension and the PB reception trunk via a time division switch. (For PB telephones) 2. Receive the dialed PB signal through the PB reception trunk and determine the signal type.

3. The control unit receives and analyzes the PB signal determined by the PB reception trunk, and recognizes it as a special number that indicates incoming call charge management.

4. The control unit connects the extension and the dial tone sending trunk via a time division switch, and sends the dial tone to the extension.

After the called party confirms this dial tone signal, he dials the calling party's area code (Figure 1b).
(indicated by middle arrow E). When the dialing of this area number is completed and billing registration is completed, the automatic private branch exchange main body 1 sends a tone signal to the extension telephone 3.
When the called party confirms this tone signal and picks up the handset, as shown in FIG. 1b, from this hook on, the incoming station line 2 is put on hold.

Next, when a series of processes related to incoming call charge management are completed, the automatic private branch exchange main body 1 calls the extension telephone 3 (indicated by arrow F), as shown in FIG. 1c. In response, when the extension telephone 3 responds (as indicated by arrow G in Figure 1 c), the hold state of central office line 2 is released, and as a result, it becomes possible to make a call (as indicated by arrow H in Figure 1 d). ), call charge management device 4
Charge calculation starts, and ends when the line is restored.

Note that the present invention can also be applied to a case where the extension telephone 3 of the automatic private branch exchange 1 is replaced with a central office line relay stand.

As explained above, according to the incoming call charge management method in the automatic private branch exchange according to the present invention,
By dialing predetermined information such as calling area information from an extension telephone or the like and transmitting it to an automatic private branch exchange, it is possible to manage charges for incoming calls like collect calls.
