Abstract

The method charges the call fee with self-equipped ordinary apparatus of the PBX. The information about the time, data subscriber code, dialed number, or kind of used line etc. is recorded on the CPU memory during the call. When completing the call, the CPU checks the dialed number whether it was a local or international one, and determines which code table is referenced according to the checking result. When there is an index code in the dialed digital code the unit time and fee rate are selected from the code table as well as the basic time and rate. The actual fee is calculated with the selected data and accumulated on the subscriber memory. The stored contents can be printed out through an I/O interface after converting the data to the ASCLL code.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of billing (call accounting) in a private exchange, and more particularly to a method of charging in the exchange itself without the help of an external personal computer.

In exchanges, it is common for the exchange to charge for the call after the subscriber call. However, the charging system has been realized only by attaching a computer in addition to the general devices used in the exchange, since the circumstances of each country and the characteristics of each item are different. This is because the memory used by the system does not meet the memory required for charging. As described above, in the related art, charging is performed by additionally connecting a computer to an exchange, which is accompanied by a problem of cost increase of the system, and a high error occurrence rate due to mutual processing of data in the exchange and the computer.

Therefore, an object of the present invention is to provide a charging method that can be charged only by the general apparatus used in the exchanger to increase the reliability according to the charging and to configure the exchange system at low cost.

Another object of the present invention is to provide a billing method that minimizes memory usage and enables easy modification even when the billing system is different or changes frequently.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an exchange system constituting the present invention. A terminal 2 and a printer 3 are attached to a normal exchanger 1 and generally such a peripheral device is added to the exchanger 1.

FIG. 2 is an internal block diagram of a general exchanger 1 as an internal block diagram of the exchanger 1 of FIG. In FIG. 1, the station subscriber ST1 is connected to the subscriber circuit 50 and the trunk line CO to the universal trunk input / output interface 80.

3 is a configuration diagram of various tables according to the present invention. The basic idea of constructing a table is to group codes according to rate and base time, and to apply the same rate and base time to codes that belong to the same group. This can reduce the amount of unnecessary memory. If you don't group them together, it will take a huge amount of memory. The code table (Fig. 3a) is a code whose contents are codes, and the code index where the corresponding code exists in the code table (Fig. 3a) becomes an important variable. The code group table (FIG. 3B) is a table for determining which rate group and which basic time group the code belongs to. The code group table (FIG. 3A) is searched with the code index obtained from the code table (FIG. 3A).

Rate table (Fig. 3c) shows rate rate determined by user's talk time according to time zone group, and consists of rate rate of initial base time and additional rate applied when exceeded. . Time zone groups will be described later. These rate rates are divided into several groups and the group designates the rates in the code group table (Figure 3b). The base time table (Figure 3d) has an initial base time and an additional base time depending on the time zone. The initial base time indicates how much base time the initial rate is applied to, and the additional base time indicates the unit time to which the additional rate is applied. These default times are divided into several groups, which are defined by the default time group in the code group table (Figure 3b). The time zone table (Fig. 3e) is a table for grouping according to the day of the week and time of the call. There are three time zone groups. For example, it can be divided into day time, evening time, night or weekend time. The slave table of FIG. 3 should be initially determined according to the charging method and the code. Once the rate group and the base time group are determined from the code group and the table, and the time zone group is determined, the actual base rate is determined by the following equation.

Talk time ＞ When the initial basic time is

×추가요금율… (1)Basic rate = Basic rate rate +

× surcharge rate… (One)

If talk time ≤ initial default time

Base rate = Initial rate

At this time, the decimal point is rounded unconditionally in the division operation result of Equation (1).

4 is a flow chart according to the present invention, which checks whether a call is completed, which records basic information on a call, and analyzes the digits of international, local, and international call, and the analysis of the first step. Accordingly, a second step of checking whether a code exists by obtaining a code index from the code table, a third step of zeroing the fee when the code does not exist in the second step, and when the code exists in the second step A fourth time group that obtains the base time group and the rate group from the code group table, the time zone group from the time zone table, the initial base time and the additional base time from the base time table, and the initial rate and the additional rate from the rate table. In the step 4, after calculating each value in the fourth step, the base fee is calculated using the data, the tax and tip are added, and the cumulative record is recorded for each subscriber. Step 5 and the sixth step of converting the call-related information and fee into ASCII form when the fee is zeroed in the third step or when the cumulative recording is completed in the fifth step, and the call-related information and the sixth step. The seventh step is to convert the fee into ASCII format, send it to the input / output interface, and send the corresponding call information to the printer.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1-4. Once the call is started, basic information related to the call is recorded in a predetermined memory in the CPU module (41). The information call start date, day and time associated with the call, the user number, the digit number dialed, and the type of the trunk line used. Then, waiting for the call to be completed (42), when the call is completed, the CPU module 50 analyzes whether the dialed digit is analyzed to determine whether it is an international call, a long distance call, or a local call (43). From this, the code table of FIG. 3 (FIG. 3A) is determined on the memory of the CPU module 50. FIG. The code table is determined by the type of currency, usually three. When the code table (Fig. 3a) is determined, it is found whether the code in the dicing digit exists (44, 441). If the code does not exist in the process (44,441), it cannot be charged (442), and if the code exists, the index of the code is taken, and the base time group and the charge of the code in the code group table (Fig. 3b) with the code index. Obtain the rate group (45). It also determines the time zone group from the time zone table (Figure 3e) with the day and time of the call. With the above data, rates are obtained from the table (Figure 3c) and the initial rate and additional rates, and from the base time table (Figure 3d), the initial base time and additional base time can be obtained (47). After comparing the talk time with the initial base time, the base rate is calculated using the above-described formula, and the actual rate is obtained by adding taxes and tips thereto (48). The subscriber is called and accumulates and records the calculated fee information in the subscriber memory (49).

On the other hand, the stored call-related information and the calculated fee are converted into the ASCII code format 491 and sent to the input / output interface 80 of FIG. 2 (492) and output to the printer 3 (493). As a result, all of the charges for one currency have been completed. When the cumulatively stored subscriber's fare is desired, inputting a command using the terminal 2 of FIG. 1 may output the cumulatively stored subscriber's fare information to the printer 3 and the terminal 2.

As mentioned above, memory can be saved by grouping the basic time, rate, and time zone, thereby allowing the user to charge with only the memory in the home without adding an external personal computer (PC). By adjusting the contents of each table according to the contents, the billing system of each country can be satisfied.
