Abstract

PURPOSE:To make a time limit supervising part for every extension unnecessary by controlling a charge indication control part so as to make an indicating part indicate a charge for a telephone call at every reception of telephone call charge information to be transmitted from a charging device at every counting of one count of the call. CONSTITUTION:The charging device (MR) 6 analyzes dial information, and investigates the speaking time per one count of the call, and stores it as classifying it for every office line trunk, and when it receives response information from a central control device (CC) 5, it starts to measure the speaking time, and simultaneously, sends first charge information to the CC 5 through an information transmission line 7. The CC 5 controls a charge indication control part (DSP) 4 provided every extension, and indicates the charge for a telephone call according to the charge information from the MR 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a call charge display system for an automatic private branch exchange.

(Prior Art) A call charge display method has conventionally been implemented in which a call charge is displayed on an extension line in a private branch exchange.

In this call charge display system, a time limit monitoring section provided for each extension updates the displayed charge by detecting the passage of a time limit.

FIG. 2 is a block diagram showing -flH- a conventional call time display method.

In the figure, when extension (hereinafter referred to as r8UBj) 1 makes a call to the central office line, 8UB1 and the central office line trunk (hereinafter referred to as ``TR'')
KJ) 3 is a switch network (hereinafter referred to as "SWJ").
) are connected via two links. 9. The central control unit (hereinafter referred to as RCCJ) 5 has a unit on the nose that calculates the total number of calls made from the number dialed by the extension, and has a time monitoring unit ( Less than 1”
(referred to as TMJ) The total number of seconds of talk per degree is set in advance.

CC5 when 3 is detected in all the response signals from the affiliated station.
controls the charge display unit (hereinafter referred to as DSP) 4 provided for each extension to display the initial charge, and also starts the TMs to perform time measurement.

When the TM8 detects that the set time limit has completely elapsed, the CC5 controls the DSP4 again to update the displayed charge. after that,
CC5 restarts TM8, performs processing to monitor the next time period, and repeats this operation.

(Problems to be Solved by the Invention) This system requires an extension line and a time limit monitoring section, and the time limit measurement process must be performed at the expense of all of the call processing capacity of the exchange.

In addition, a function was required to obtain the total number of seconds of communication per call from the private branch exchange's partner number information. However, such a function is also an essential function of a billing device. Therefore, in a private branch exchange to which a charging function (t) is added, the charging device and the private branch exchange must each have the same function, which has the disadvantage of creating waste.

Is the purpose of non-invention to have all the functions of the billing device and automatic private branch exchange number redundant? To provide a call charge display system which eliminates the need for central control planning of an automatic private branch exchange, reduces the burden of central control, and facilitates maintenance of the automatic private branch exchange.

(Means for Solving the Problems) In order to achieve the above object, the call charge display method according to the present invention is a call charge display method in an automatic private branch exchange.
1 display section! a charge display control unit that controls the charge display on the display unit; a charging device that performs charging processing for each central office line trunk based on dial information and response information of the other subscriber; Provides information necessary for billing, and controls the charge display control section to display the call charge on the display section each time the billing device receives a call charge report sent out every time the billing device completes the count. and a control means for controlling the system.

(Example) The present invention will be described in more detail below with reference to all 9 pages.

FIG. 1 is a block diagram showing an embodiment of a call charge display method according to the present invention.

In the figure, the same components as in the conventional example are given the same reference numerals as in FIG. 2. CCs is equipped with a general charging device (hereinafter referred to as r) that performs charging processing based on information obtained through CCs.
(referred to as MRJ) 6 is connected, and in Fig. 2, 5UBI
TM8 provided for each has been deleted.

CC5 also serves as a control means for controlling call charge display.

Each 5UB1t is provided with a display section (not shown), and the call charge is displayed on this display section.

Next, the operation will be explained.

When 80B1 goes off-hook and dials the special number for the central office line, CCs controls SWz and sends 5UH1 and T,
At the same time, the tR report indicating that 5UH1 has captured the central office line via TRK 3'i is sent to MI (, 6) via all information transmission paths 7. After that, when 8UHx dials all the other party's numbers, the A dial signal is sent to the department via the TRK 3-i.The CC 5 sends this dial information and the response information of the other person detected via the TRK 32 to the MB 2 via all the information transmission paths 7.

MB2 analyzes the dialing information to find out the call time per call, stores the number for each central office trunk, and when it receives the response information from CC5, starts measuring the call time, and also records the initial charge information. is sent to the CC 5 via the information transmission path 7.

CC5 is set up on the extension line and pDsP471 based on the charge information from M6. control and display call charges. In addition, MB2 adds up the unit charge for each office line trunk to the installed charge meter (not shown) based on the call time for one time checked earlier, and calculates the total amount?Information transmission path 7 Send CC3G via.

The CC 5 controls the DSP 4 to update the charge display every time it receives all call charge information.

(Effects of the Invention) As explained above, according to the call rate display method according to the present invention, a time limit monitoring unit for each extension is not required, and the central control unit does not perform time limit monitoring, so its load is reduced. Not a fool.

In today's world, where rate revisions are frequent, only the depreciation equipment handles the entire rate revision process, while the private branch exchange does not need to do so.

Maintenance is also easier.
