3 and 4 are flow charts for carrying out the present invention. FIG. 3 is a flowchart illustrating data input performance related to a fee system according to the present invention, and FIG. And, Figure 5 is an example of the charge data output form according to the present invention.

That is, in order to carry out the present invention, the first RAM 13 of the key phone main controller 10 selects a specific mode of any one key phone dedicated phone (key phone station phone) and inputs the tariff related data through key input. This process should be stored in the following.

In general, the fare system is roughly divided into local, intercity, and international rates. However, the local call rate is applied uniformly, but the international call rate and the long distance call rate are different according to the country and region, so if the country code and the area code called by the caller are recognized, the caller used the caller. The relevant data should be entered in advance so that the appropriate rate can be calculated. In addition, if the charge is changed according to the day and date, and if the charge is changed according to the time of day, a separate related data should be entered.

Accordingly, in the preferred embodiment of the present invention, as shown in FIG. 3, first, a country code of each country required for an international call is input (301), and a fee calculation calender for changing a fee system for days and dates is input. (302) In operation 303, a fee calculation timetable for changing a fee system according to a time zone is input. In addition, the domestic and foreign area code (DDD) is input and the respective fare class is entered (304). Thereafter, the fare system-related data input process is terminated by inputting the fare system for each fare system (305).

Through this process, after inputting the data related to the call charge for displaying the call charge to the first RAM 13 of the main controller 10 of the key phone system as shown in FIG. 2, the call phone system is connected. Whenever any extension subscription attempts to talk to the outside, the operating program stored in the first ROM 12 of the keyphone system is operated as follows to perform the method of the present invention.

First, when an extension subscriber occupies an idle CO line to make an outside call, the charge system of the call is determined according to the input phone number and call start date, time, and day of the call required (401), and the call time is counted. The first CPU 11 checks whether the toll is at the start time and waits if the start time is not reached (402). If the start time is reached, the cumulative charge is calculated immediately according to the rate of the rate system determined in step 401. Then, the calculated call rate output data is transmitted to and displayed on the phone station telephones 40a and 40n of the extension subscriber who is currently calling (403). In an embodiment of the present invention, the charge charge start time is set to a specific value within 2 seconds to 32 seconds according to domestic, international, and regional classification, so that the set salary is calculated according to the time interval and the charge system. And accumulate for each of the station phones 40a and 40n in the call and display the corresponding charges on the subscriber station phone display 42 of each subscriber.

Then, the first CPU 11 checks whether the use of the corresponding CO line has ended, that is, whether or not the call is completed (404). After repeating the call, if the call is over, the data on the fee is output to the printer 50 to be printed out (see example of the output form in FIG. 5). On the other hand, according to the present invention, it is possible to easily store the result data for the call charges in the memory to calculate the cumulative charges and various statistical data of each subscriber.

5 is an exemplary view of a fare data output form according to the present invention, in which (1) is a call start time (mmm well, dd-day, hh-hour, mm-minute, ss-second), ( 2) is the call time (hh-hour, mm-minute, ss-second), (3) is the subscriber number (nnn), (4) is the station number (nn), and (5) is the call rate Related message (vvvvvvvvv-call rate), (6) call division (LOC-local call, DOM-long distance, IMT-international call), (7) dial number (up to 25 digits, not including PBX code) And (8) is an example configured to include an extension subscriber number (or a blank if not converted) that converted the call when the call was switched.

In addition, by using the method of the present invention, charges including tax and depreciation of equipment can be imposed when a fee is charged, and when a fee limit is exceeded by inputting a fee allowance limit of each extension subscriber, the system can restrict the call of the subscriber in the system. Not only can it be used, it is a very useful invention that can be used to issue receipts.

In the present invention as described above, the user can immediately check the call charge by displaying the charge and call time to the corresponding user according to the call start time and the domestic / international / local telephone respectively in the plurality of subscriber station telephones in the key phone system. It is possible to eliminate the doubts related to the administrator of the key phone system has the effect of making it easy and efficient system management by printing the call charges and cumulative usage charges to the printer when using each extension subscriber.
