Referring to the operation of the present invention configured as described above are as follows.

When the telephone is called, the ring detection unit 1 detects a ring signal input through the telephone line 15 to ring a ring, and receives and receives data (caller's telephone number) input along with the ring signal. The unit 5 supplies the data to the CPU 10, and the CPU 10 causes the incoming caller phone number data to be displayed through the display unit 13 so that the user can receive a call after confirming the caller's phone number. To help.

According to the present invention, when a user makes an international call, a long distance call, or a mobile phone, the user can receive a rate discount service automatically.

That is, in the call waiting state, the user presses the specific key K1 provided in the phone for a predetermined time, and the CPU 10 automatically switches to the rate discount mode as the specific key K1 is input, and displays the display unit 13. ) 'Select' displays the Hangul icon so users can confirm that they are currently in charge discount mode.

In this state, when the user sequentially presses a country selection number, an area code, or a phone number to make an international call, the CPU 10 recognizes that the user is making an international call and calls a special number that is discounted when making an international call. By sending in front of the telephone number entered by the user, the user does not have to press a special number for the discount rate.

In addition, when the user presses the area code and phone number to make a long distance call, the CPU 10 recognizes that the user is making a long distance call and calls a special number for which the fee is discounted when making the long distance call. It is sent out in front so that the rate discount service is applied.

As a special number currently being implemented, a discount service such as '00770' is used when making international calls and '008' is used when making long distance calls, so the CPU 10 stores the special number as described above. When dialing an international call, a long distance call, or a mobile phone, the special number is automatically dialed first so that a discount rate benefit is given to the user.

In addition, when the user enters a phone number to make a call to a regular phone in the state where the rate discount mode is set as described above, the CPU 10 recognizes that the user wants to make a general call and the special number is not sent. By default, it is temporarily bypassed in normal call mode.

On the other hand, when the user wants to cancel the fare discount mode, the user presses the specific key K1 again for a predetermined time in the call waiting state, whereby the CPU 10 recognizes that the specific key K1 is input and is currently set. It is to release the rate discount mode to the general call mode, and when the user wants to make an international call, a long distance call, or a mobile phone while the general call mode is set, the special number is not sent.

In addition, the telephone of the present invention has various functions such as a one-touch transmission of a phone number stored in advance by using speed dial keys (M1 to M8). It will be omitted.

As described above, the present invention stores a special number of discounted rates when calling international calls, long distance calls, and mobile phones in the CPU, and switches to the rate discount mode when a specific key is input, and the user enters the phone number. By automatically sending a special number at the beginning of the call, the user can expect the effect of providing a discount rate control device for the caller display phone, which increases the convenience of use by eliminating the user from having to memorize special numbers that are discounted. have.
