To control the signal.

Next, the operation of the device having the above configuration will be described.

First, registration / change and deletion of a caller ID and a ring signal (ring tone) for the telephone are made through the key input unit 14. In order to register caller ID and ring signal, when user selects caller selective call mode by operating MENU / setting key 14a and search key 14e, microprocessor 1 registers through LCD display unit 2. A character is displayed to input a desired caller ID. In this state, when a user inputs a desired caller's phone number and name by operating a numeric / character key 14d of the key input unit 14, a ring signal (ring tone) is selected. Characters will appear on the LCD display 2. At this time, the ring signal (ring tone) is selected by operating the search key 14e. Then, when the storage key 14b is operated, the microprocessor 1 stores the caller ID and ring signal (ring tone) selection number input by the user in the caller ID storage unit 3.

In addition, when the user changes the caller ID and selects the caller ID search mode by operating the MENU / setting key 14a and the search key 14e, the microprocessor 1 sends the caller ID storage unit 3 to the caller ID storage unit 3. When the stored caller ID is output to the LCD display unit 2 and the user operates the search key 14e and selects the desired caller ID while selecting the delete caller 14c, the microprocessor 1 corresponds to the corresponding caller ID. The caller ID is deleted from the caller ID storage 3. If the caller ID is selected and the caller ID is changed by operating the search key 14e and the numeric / character keys 14d, and the storage key 14b is selected, the microprocessor 1 stores the changed caller ID and stores the caller ID. It is stored in the unit (3).

Next, a caller selective call function using a caller ID and a ring signal according to the present invention will be described with reference to the operation flowchart shown in FIG. 3.

3 shows an operation flowchart when the caller selective call mode is set by the MENU / setting key 14a and the retrieval key 14e of the key input unit 14.

As shown in FIG. 3, when the user operates the MENU / set key 14a and the search key 14e to set the caller selective call mode (SIT1), the microprocessor 1 preferentially sets the caller selective call mode. Switch to the caller selective call mode program to perform the (SIT2).

Subsequently, when the ring signal input is detected by the ring signal detector 5 in the above state (SIT3), and the caller ID is detected by the caller ID detector 6 (SIT4), the microprocessor 1 determines the caller ID detector ( 6) By searching the caller ID input unit 3 through the caller ID storage unit 3, it is searched whether the same caller ID stored in the caller ID storage unit 3 is stored in the caller ID storage unit 3 (SIT5). . In addition, the microprocessor 1 displays the caller ID received through the caller ID detection unit 6 on the LCD display unit 2.

When the same caller ID is found (SIT6), the microprocessor 1 selects a ring signal corresponding to the received caller ID from the ring signal selector 4 (SIT7). In this case, the ring signal selected by the ring signal selector 4 is input to the ring signal generator 11 so that the selected ring signal is output by the ring signal generator 11 (SIT8).

In addition, when the caller ID is not detected in the caller ID detection unit 6 in the SIT4 step or when the caller ID received in the SIT6 step does not match the caller ID stored in the caller ID storage unit 3, the microprocessor The ring signal selector 4 selects a general ring signal (SIT9). In this case, therefore, the general ring signal selected by the ring signal selector 4 is input to the ring signal generator 11 so that the selected general ring signal is output by the ring signal generator 11 (SIT8).

As described above, according to the present invention, when a user requests a call from a desired caller, the user can output a unique ring signal to select and talk with an unspecified call request or to effectively reject an unspecified call request. It can effectively cope with unnecessary call requests such as telephone, indecent phone call) and telemarketing.
