Abstract

The present invention relates to a method for reducing call rates, and in the related art, when a long distance call or an international call is used, the number of a telecommunications company serving the same (eg, an area code for long distance call (02, 051, 082-02, 082- 051, etc.) or when a user presses a telephone company's telephone number (001, 002) for the purpose of making an international call, but the call charge system is different between a long distance or international service provider, There is a problem that the user does not know which carrier's number to use to obtain the optimal telephone bill service. In the present invention, a method of automatically selecting a carrier and a communication line is selected by the simple switching device. It is effective in reducing call charges.

Description

How to Reduce Call Rates

The present invention relates to a method for reducing call rates, and in particular, to reduce the call charges between telecommunication companies servicing long distance calls or international calls. It is about.

Conventional methods, when using long distance or international calls, include the number of the telecommunications company that serves them (e.g., area code for long distance calls (02, 051, 082-02, 082-051, etc.) or for international calls. The user directly pressed the telephone company number (001, 002) and made a call.

In the conventional method as described above, since the call rate system is different between the telecommunications companies serving the long distance or international calls, it is necessary to use the number of the telecommunications company at the time to be used for the optimal telephone rate service. There was a problem that the user did not know.

Accordingly, an object of the present invention is to provide a method for automatically selecting a telecommunication company and a communication line in a simple switching device.

With the configuration of the present invention for achieving the above object, Figure 1 is a trunk line / extension connection diagram using a simple switching device, as shown therein is a simple to control the call between the trunk line and the station of the telephone line of the telephone station A main unit 10 of the exchange apparatus; It is composed of an extension terminal 20 to make a call with an external subscriber under the control of the main device 10, and in particular, the program 30 is built in the main device 10 to perform all functions of the simple switching device. In addition, a call rate reduction method, comprising: a first step of confirming a number of dials initially designated by a program previously inputted in a central processing unit when occupying trunk lines; A second step of checking whether there is a corresponding number on the rate saving number table stored in the memory unit with respect to the number identified in the first step; A third step of transmitting the code on the fee saving number table to the trunk line with respect to the number identified in the second step; The present invention configured as described above will be described in detail with reference to the accompanying drawings.

2 is an operation flowchart of the method of reducing the call rate of the present invention. As shown in FIG. 2, the central processing unit and the program 30 of the simplified switching device check whether the trunk line is occupied by the extension at any time, and by any extension. When the CO line is occupied, the program 30 checks whether the first number of the telephone number dialed by the extension terminal 20 is '0', and if the first number is not '0', transmits the input number as it is to the CO line. If it is '0', it waits without sending out to the CO line until the input becomes 3 digits, and when the input of the dialed telephone number is 3 digits in the extension terminal 20, then the program 30 enters the 3 digits. Check for a number that matches the number in the program and the number on the fare savings number entered on the program (eg, area code for long distance calls (02, 033, 051, etc.) or international Telecommunication company number (001, 002, etc.) for the purpose of telephone, however, these numbers must be entered in advance on the program (30).

If the number dialed by the user is present on the tariff number table, the dial number for tariff reduction is also read on the tariff table (eg, dial number 082 for assigning dacom, etc.) and then sent to the trunk line and the user enters it. If one dial is sent to the trunk line, and the number dialed by the user is not present on the toll-free number table (eg number 080 for toll-free service, 011, 017, etc. for mobile cordless telephones, and for pagers) 012, 015, etc.) The number entered is sent to the CO line as it is.

As described above, when using the long distance or international telephone according to the present invention, the call fee system between the telecommunication companies serving the same is different, and the information is stored in the simple switching device so that the simple switching device automatically By selecting the lowest cost communication line and making a call, the call fee can be saved, and the user can eliminate the inconvenience of finding the low cost communication line.

Claims (2)

1. A communication device, comprising: a first step of confirming a number of dialing initially designated by a program previously entered into a central processing unit when occupying a trunk line; A second step of checking whether there is a corresponding number on the rate saving number table stored in the memory unit with respect to the number identified in the first step; A third step of transmitting the code on the fee saving number table to the trunk line with respect to the number identified in the second step; And a fourth step of transmitting a dial other than the number specified in the first step to the trunk line as it is. The method of claim 1, wherein the call rate saving table comprises a dial that the user has previously entered in a memory using a key button.
