Abstract

PURPOSE:To attain the service charge management at each telephone number as to a private line by providing a means calculating the talking time by the private line at each telephone number corresponding to an extension telephone set. CONSTITUTION:When talking is performed between an extension telephone set 2-n of a telephone exchange I and an extension 15-n of an exchange II via a private line 6-n and the talking is finished, a central control unit sends the data such as talking time of the telephone set 2-n, telephone number and outgoing or incoming call to a talking charge management section 10. The section 10, in case of outgoing call, the talking time of each telephone number, total talking time of all private lines 6-1-6-n and the data of talking time to be sent are added, and in case of an incoming call, the data is added to only the total talking time of all the private lines. Thus, the section 10 adds the talking time at each private line talking, and obtains the private line charge per each telephone number by using the rate of each telephone number to the total talking time of all the private lines and the charge of the all private lines stored in advance in the section 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Graduate Field of Use) The present invention relates to a call charge management system for a leased line in a telephone exchange.

(Prior Art) FIG. 3 is a block diagram of a telephone private branch exchange, including a switching circuit (1), extension telephones (2-1) to (2-n), and an extension circuit (3) connecting the switching circuit and extension telephones. -1) ~ (3-n
), station line (4-1) to (4-nX station line circuit connecting (5-1) to (5-n''), dedicated mc6-1)
~ (6-n), dedicated line circuit (7-1) for connecting dedicated lines
- (7-n), control unit (8), storage unit (9), call charge management unit (10) that manages and stores call charge data.
, and a maintenance terminal (11) for inputting setting data.

In a conventional telephone switching system with such a configuration,
Call charge management for each telephone number was performed only for calls made to central office lines (subscriber lines), and not at all for calls made to leased lines.

The method of managing call charges when making a call to a central office line from an extension telephone is as shown in the flowchart of FIG.

When dialing the special number to capture the central office line (4-n) from the extension telephone (2-n), the extension telephone (2-n) -
Extension circuit (3-n) - Exchange circuit (1) - Office line circuit (5-
n)-office line (4-n) is connected, and when the subscriber's telephone number is subsequently dialed, a dial is sent to the office line (4-n) (step 401). At this time, the telephone number of the extension that made the call to the office line and the dial sent to the office line (4-n) are stored in the storage unit (
9) (step 402).

When the called party answers (step 403), the central control unit e (8) starts counting up the call time, and continues counting up until the end of the call (step 404). Upon ending the call (step 405)
The call charge management unit (10) calculates the call charge based on the outgoing dial and call time, and stores the result for each telephone number (step 406).

The call charges for each telephone number stored in this way can be totaled by the call charge management unit (10) on a daily, weekly, monthly, etc. basis.

(Problems to be Solved by the Invention) As mentioned above, in the conventional call charge management system of telephone exchanges, call charges are managed for each telephone number when a call is made from an extension telephone to a central office line. Because lines are charged only by paying a predetermined rental fee, no consideration had been given to managing call charges for each phone number when making a call to a dedicated line. Therefore, if an extension user
It was not possible to determine how much the leased line was used for.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a call charge management system for a telephone exchange that can eliminate the above-mentioned drawbacks and manage call charges for each telephone number even for leased lines.

[Structure of the invention]

(Means for Solving the Problems) The present invention is configured by including means for calculating the call time on a dedicated line for each telephone number corresponding to an extension telephone.

(Function) The present invention is equipped with the means described above, and the call time for the dedicated line of an extension telephone is calculated for each telephone number compatible with this extension telephone. It follows that the leased line usage fee for each phone number can be determined from the total line rental fee.

(Example) FIG. 1 is a schematic diagram showing a configuration in which two telephone exchanges are connected by a dedicated line, and the components of each telephone exchange are as shown in FIG. 3. Below, the first
Focusing on telephone exchange I in the figure, a method for managing call charges for a dedicated line will be explained in accordance with the flowchart in FIG.

A dedicated line call is made from the extension telephone (2-n) of telephone exchange I to the extension telephone (15-n) of telephone exchange n) to telephone exchange ■ extension telephone (15-n)
There is an incoming call on the dedicated line, and when you answer it, the telephone extension (2-n) - extension circuit (3-n) - exchange circuit (1) -
Dedicated line circuit (7-n) - Dedicated line (,6-n) - Dedicated line circuit (12-n) - Exchange circuit (13) - Extension circuit (14-
n) - The extension telephone (15-n) is connected and a call is started (step 201). At this time, the central controller (8) controls the extension telephone m(2-n) that started the leased line call.
) is stored in the storage unit (9), and the call time count-up is started regardless of whether the call is made or received (steps 202 and 203). The call time count-up continues until the end of the call.

When the call ends (step 204), the central controller (
8) The call time, extension phone number, and call are on the extension phone (
2-n) is transmitted to the call charge management section (10) (step 205).

In the case of a call, the call charge management unit (10) adds the sent call time data to the call time for each phone number and the total call time for all leased lines (6-1 to 6-n). step 206), and in case of incoming call, all dedicated lines (6-1 to 6-6-
The sent data is added only to the total call time of n) (step 207).

As described above, the call charge management department (lO) adds the call time each time a leased line call is made, and adds the call time for each phone number to the total call time of all leased lines (6-1 to 6-n). The percentage of call time and the call charge management department (
10) Find the leased line usage fee for each telephone number from the rental fees for all leased lines (6-1 to 6-n) stored in .

For example, to find the monthly leased line usage charges for each phone number, calculate the call time for each phone number and the total leased line usage charge for each phone number at the beginning of the month. (
The call time values of 6-1 to 6-0) are set to the initial value "0", and thereafter, each time a leased line call is made until the end of the month, each call time is added in the above method. Then, the call fee management unit (io) performs the calculation at the end of the month, thereby making it possible to determine the leased line usage fee for each telephone number.

In addition, using the same method, it is also possible to obtain the leased line usage charges for each telephone number, such as daily or weekly. Further, in the case where the rental fee for the leased line is only for the outgoing call, it is also possible to calculate the fee based only on the call time related to the outgoing call.

〔Effect of the invention〕

As explained above, since it is possible to calculate call charges for each telephone number on a leased line, it is possible to bill call charges for each telephone number or group of telephone numbers for a leased line as well as for a central office line. There are advantages.
