Description

How to Display Call Rates and Number of Calls

The present invention relates to a method of displaying a call charge and the number of calls of a telephone terminal, and more particularly, to a method of accumulating and displaying a call charge and the number of calls each time a telephone terminal makes a call.

Typically, the talk time is used to charge each subscriber by counting when each subscriber forms a call in the exchange system. However, subscribers could not find out how many local and long distance calls they had made over a period of time, even if they were actually using their telephones, and received a notification of how much the telephone charges were. Therefore, after the telephone call, the user was required to recognize the call rate and the number of calls for a certain period of time.

Accordingly, an object of the present invention is to provide an apparatus and method for accumulating and displaying a call charge after a call in a telephone.

Another object of the present invention is to provide an apparatus and method for accumulating and displaying the number of calls each time a phone call is made.

In order to achieve the above object, the present invention calculates and stores the number of calls accumulated in each region and the call rate according to the unit time for each region each time an outgoing call is made in the telephone terminal, and then selects the number of calls / call rates. When the key is input, the call charge and the number of calls are displayed.

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

1 is a block diagram of a telephone terminal for displaying a call charge and the number of calls according to an embodiment of the present invention.

The key input unit 10 generates a key command for controlling the operation of the phone by the user, a region setting key, and call rate and number of call selection key data. The central processing unit 12 receives the key signal of the key input unit 10 to control the overall operation of the phone, and controls to display by counting the phone call charge and the number of calls. The memory 14 stores call time and call count data generated when the control program and the overall control operation of the CPU 12 are performed. The line interface unit 16 is connected to the public telephone network through a telephone line, and interfaces ring signals, tone signals, and voice calls signals between the telephone and the public telephone network. The voice input unit 20 is configured as a microphone or a transmitter to convert a voice signal generated from the subscriber into an electrical signal and output it. The voice output unit 22 is composed of a speaker or a handset to generate an audible sound by converting an electrical signal into a voice signal. The communication circuit unit 18 is connected to the voice input unit 20 and the voice output unit 22 to switch to each unit by a control signal of the CPU 12 to form a communication path. The display unit 24 displays the call charge and the number of calls under the control of the CPU 12. The timer unit 26 counts a predetermined clock and outputs time data to the CPU 12. The ring detector 28 has an input terminal connected to the line interface unit 16 and detects a ring signal input through the line interface unit 16.

Referring to FIG. 2, in step 101, the controller 12 checks whether the hook is off. In this case, if the hook is off, the controller 12 receives the dial number input by the user through the key input unit 10 and performs dialing. Then, in step 103, the control unit 12 checks whether the communication path is established with the other party. If the communication path is not established with the other party, the controller 12 proceeds to step 104 when the user dials or the other party is in a busy state. In this case, the call path is cut and restarted from step 101. However, if a call path is established with the other party in step 103, the call proceeds to step 105, and the timer 26 is driven to count the talk time per unit time according to the corresponding region, and then proceeds to step 106. If it is determined in step 106 that the device is hooked up, the unit call time is continuously counted. If the device is hooked up, the process proceeds to step 107. In step 107, the control unit 12 converts the counted unit call time into a set rate of a corresponding area, calculates a call rate, and proceeds to step 108. In step 108, the control unit 12 stores the calculated call rate in the corresponding region call rate region of FIG. In step 109, the controller 12 increases the number of call counts according to the region by 1 and proceeds to step 110. In step 110, the controller 12 stores the call count count value according to the corresponding region in the corresponding region call frequency region of FIG. 3 of the memory unit 14.

4 is a control flowchart for displaying a call charge and the number of calls according to an embodiment of the present invention.

As described above with reference to FIG. 4, after the call is completed and the call rate and the number of calls are calculated and stored, the call rate and the number of times are checked. If yes, go to step 102. In step 102, the controller 12 checks whether the input key is a number of times / call rate selection key. If the input key is a call count / call charge selection key, the controller proceeds to step 203. In step 203, the controller 12 displays the call count and call charge stored in the memory unit 14 on the display unit 24. However, in step 202, if the input key is not the number of times / call rate selection key, the function corresponding to the input key is performed.

As described above, the present invention stores and stores the call rate and the number of times counted for each region each time an outgoing call is made by the phone terminal, and then the call rate and the number of times when the call frequency / call rate selection key is input. By displaying the user can know how long and long-distance local calls, and after checking the used call rate, there is an advantage that can save the call rate by refraining unnecessary phone calls.
