Abstract

PURPOSE:To omit time and labor to input station data and to generate call tariff basic data at every area throughout the nation by generating a tariff classified by every dial by inputting the number of its own station from charge data input terminal equipment before operating a device, and using only the tariff when operating the device. CONSTITUTION:A central processing unit to store data representing the geographical positions of nationwide area codes and the data representing relation between a distance and the call tariff and input terminal equipment to input the area code are provided. The central processing unit performs distance calculation in fee calculation from a subordinate station to each area station based on a subordinate station area code inputted from the input terminal equipment and the geographical position data of all area codes, and generates the correspondence table of the area code with a fee by using the data representing the relation between the distance and the fee. And the table is changed to the tariff classified by every dial, and is stored in a memory device as the station data, and the central processing unit calculates the fee based on the tariff classified by every dia[, and uses only the tariff when the device is operated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a call charge calculation method in a private branch exchange system, and is for creating a charge list for each dial.

[Conventional technology]

The charge list for each dial is recorded as station data before equipment operation.
The distance between the installed station and each area code was checked and entered using the attached terminal device. Another method used was to have geographical location data for national area codes, and each time the exchange received a called number, the distance was calculated from the location of the local station and the location of the other party, and the call charge was calculated.

[Problem to be solved by the invention]

In the former method, it takes time to input data, and input errors occur when inputting data.

The latter has drawbacks such as requiring a huge amount of memory because it requires geographical location data for national area codes when operating the device.

[Means to solve the problem]

The present invention solves the above-mentioned drawbacks by inputting the own station number from the billing data input terminal device before operating the device, creating a dial-specific charge table, and using only this charge table during operation.

[Effect]

By inputting the area code of the installation island from the billing data input terminal device, you can easily create a dial-by-dial rate table anywhere in the country, and even if there is a change in the basic call rate, this table can be used with the attached input device. can be easily changed from

〔Example〕

The invention will be specifically described below according to embodiments shown in the drawings.

FIG. 2 is a schematic configuration diagram of a general electronic private branch telephone switching system, where COT is a central office line trunk, CPU is a central processing unit including a switch processing section and a billing section, CL is a billing data input terminal device, and TA- TC indicates an extension terminal such as a relay stand or an extension telephone.

FIG. 3 is a diagram showing the configuration of data files held by the billing processing section of the central processing unit CPU according to the present invention, where / indicates the geographical location of the national area code. ．． 2 shows the correspondence table of nationwide area codes and charges, D1, D,, 2 is the first dial excluding the area code O, D3゜Dll- is the third dial excluding the area code 0, 3 is the separate dial Shows the price correspondence table.

FIG. 7 is a flowchart showing an embodiment of the present invention and explaining the operation of billing processing by the central processing unit CPU;
The operation will be explained below in comparison with FIG.

Before operating the device, when you input your own station dial from the data input terminal device LC (step /), search for your own station position from the geographical location table of national area codes (Figure 3 /).Step 2), the top of the table The distance to each toll office is calculated in order from the beginning to the end, and basic data (not shown) is stored in the central processing unit based on data showing the relationship between distance and charges (Step 3. ).

Among this data, data corresponding to an adjacency table (not shown) is changed to adjacency. (Step q).

Next, compare basic charge data in order from dial/digit/(D/) from this table, and if different, up to 3 digits C
03, Execute D1 and set basic charge data. A comparison is made up to the /th digit (D, 2) and a charge table for each dial is created (Step 6, Fig. 3). This table is used during operation.

That is, it is equipped with a central processing unit that stores data indicating the geographical location of a national area code and data representing the relationship between distance and call charges, and an input terminal device for inputting the area code; Data indicating the relationship between distance and fee by calculating the distance from the affiliated station to each toll station based on the area code of the affiliated station input from the terminal device and the geographical location data of all the area codes. Create a table of correspondence between area codes and charges using
When the central processing unit receives information regarding the called number and call time from the exchange, it calculates the charge based on the dial-by-dial charge list stored in the storage device and stores it in the storage device for charge storage. Stored in a storage device. Only this price list will be used during operation.

Note that calls in the main text include data calls, area codes include centralized calls, and the rate list for dialing includes international dialing and N.
This includes TT service dials such as 10 da, and the rate list for each dial can be changed using the attached input device.

〔Effect of the invention〕

As described above, according to the present invention, the device operation is also i? By creating a charge list for each dial in J, the time and effort of inputting station data can be saved and the amount of effort required during operation can be reduced. or,
It has the advantage of being able to create basic call charge data for any region in the country.
