Abstract

PURPOSE:To calculate a formal talking charge with respect to a talking without an NCC access code by referencing a dial information file and a line dependent talking charge index file so as to calculate the usage charge. CONSTITUTION:A private branch of exchange (PBX) is provided with an exchange section 1, and line circuits of telephone sets (TA-Tn), office line trunks (COTA1-COTAn) connecting to a general public network, office line trunks (COTB1-COTBn) connecting to an NCC direct line are connected to the exchange section 1. Moreover, a charge calculation section 2 comprising a central processing unit (CPU) managing the charge, an input/output device (CS) entering station data or the like and outputting a maintenance and talking detail sheet or the like and a storage section (MM) is connected to the exchange section 2. Then the CPU of the charge calculation section 2 references a dial information file and a line dependent talking charge index file, calculates the utility charge and calculates the talking charge of each NCC direct line network to be used without an access code of each NCC.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic / international NCC company charge calculation method used by each extension connected to a private branch exchange system.

[0002]

2. Description of the Related Art In a conventional usage charge calculation method, that is, a call charge calculation identification method, a call charge for each NCC is calculated by determining an access number to each NCC and an area code. Also, the charges for each NCC are only official call charges.

[0003]

In the prior art, each N
If there is no CC access code, the call charge cannot be calculated, and the NCC usage charge cannot be calculated.

The present invention enables a formal call charge for a call without an NCC access code such as when each NCC direct line is used, and optionally exchanges this call for NCC transmission via a public network. The purpose is to be able to.

[0005]

In order to achieve the above-mentioned object, the present invention provides a dial information file (ND) for determining the use of a telephone line of a telephone (TA to Tn), and this dial information file. Equipped with a line-by-line call charge index file (KD) for calculating the call charge based on (ND) information. It is characterized in that the charge calculator calculates the usage charge by referring to the charge index area when the line is used.

[0006]

With this usage charge calculation method, the extension telephone (TA) makes a call, the exchange (PBX) selects an office line, and the central control processing unit (CPU) of the charge calculation unit makes the dial information file (ND) ) And the call charge index file (KD) for each line, and calculate the usage charge for each N used
Call charges for the CC direct line network are calculated without the access code of each NCC.

[0007]

The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 is a block diagram showing the configuration of a telephone exchange system used in the usage charge calculation method of the present invention.
In FIG. 1, a telephone exchange device (PBX) includes an exchange unit 1. The exchange unit 1 includes line circuits of telephones (TA to Tn) and a station line trunk (CO) connected to a general public network.
TA1 to COTAn) and trunks (COTB1 to COTBn) connected to the NCC direct line are connected,
In addition, the exchange unit 1 includes a central control processing unit (CPU) for performing charge management, a charge calculation including a console (CS) for inputting / maintaining station data etc. and outputting call details, and a storage device (MM). The part 2 is connected.

FIGS. 2A, 2B and 2C are diagrams showing the structure of a data file necessary for performing the usage fee calculation method according to the present invention.

FIG. 2 (a) shows a local line (COTA1 to COT).
An) and (COTB1 to COTBn) are used line identification FG registration files (TU) prepared correspondingly.

FIG. 2B shows a dial information file (N) for judging the use of the central line of the telephone (TA to Tn).
D), the outgoing dial (20-0 to 20-n) for saving the outgoing dial, and the used line identification FG area 2
It consists of 1.

FIG. 2C shows a dial information file (N
This is a call charge index file (KD) for each line to calculate the call charge based on the information in D), and the charge index area (21-0 to 22-n) when using the general public network and the NCC direct line use It consists of hourly charge index areas (22-0 to 22-n).

FIG. 3 is an operation flow chart of the embodiment of the present invention.

The operation of the present invention will be described below with reference to FIGS.

When the telephone (TA) presses the calling special number (step S301), the PBX causes the central line (CO
TA1 to COTAn) and (COTB1 to COTBn) are determined to supplement the station line (step S302), and the telephone (T
From A), press the outgoing dial (step S30
3), the used line identification FG registration file (T in FIG. 2A)
Figure 2 shows the data and dial information registered in U).
It is saved in the dial information file (ND) shown in (b) (step S304), and the central control processing unit (C
Based on this information, the PU) refers to the table of the line-based call charge index file (KD) in FIG. 2C to calculate the charge (step S305).

When the telephone (TA) ends the call (step S30
6) Determine the call time and calculate the final charge.

The call charge of each NCC can be set freely via the general public network or via the direct line when registering the used line identification FG registration file data of FIG. 2 (a), and calculate any call charge. You can

[0018]

According to the present invention, the extension telephone (TA) makes a call, the exchange (PBX) selects an office line, and the central control processing unit (CPU) of the charge calculation unit makes a dial information file (ND). Since it is possible to calculate the usage charge by referring to the line-specific call charge index file (KD), it is possible to calculate the call charge of each NCC direct line network used without using the access code of each NCC. Moreover, by registering the data, the call charge of each NCC can be calculated at an arbitrary call charge.
