The digit is the telephone number you want to store, and the letter represents the user's name.

FIG. 1 is a block diagram of a conventional digital mobile communication terminal, which describes a configuration of a digital mobile communication terminal for receiving the aforementioned service.

First, the controller 10 may control the overall operation of the digital mobile communication terminal and realize it as a one chip microprocessor. The memory 20 stores a predetermined program for controlling the overall operation of the mobile phone, and stores data input and output and various data processed when the overall operation of the digital mobile communication terminal is performed by the controller 10. In particular, a speed dialing table having phone numbers for a plurality of speed dial keys having the configuration shown in Table 2 is stored. The key input unit 30 includes a plurality of numeric keys, and generates corresponding key data when the user presses a predetermined key and outputs the corresponding key data to the controller 10. The display unit 40 includes a liquid crystal display unit for displaying various types of information, is controlled by the controller 10, and receives and displays key data generated by the key input unit 30 and various information signals of the controller 10. The display unit 40 may be implemented as a liquid crystal display (LCD). The audio unit 70 processes voice signals input and output through the speaker SP and the microphone MIC. In addition, the audio unit 70 detects the ring signal through the transceiver 60 and the modem 50 when a ring signal is generated from the base station, and transmits a ring tone through a ringer. The modem 50 demodulates and demodulates the data inputted and outputted to the control unit 10, and modulates and demodulates the audio signal inputted and outputted to the audio unit 70. The transceiver 60 converts a radio signal received through the antenna into a signal of an intermediate frequency, converts a modulated signal output from the modem 50 into a radio signal, and transmits the radio signal through the antenna.

Hereinafter, referring to FIG. 2, the base station continuously checks whether a call has been received in step 201. When the call is received, the base station switches to the communication terminal of the call in step 203. After switching to the call in step 203, the base station determines whether the communication terminal of the switched call is busy in step 205. In step 205, if the communication terminal of the call is busy, the base station proceeds to step 207 and transmits an alarm tone signal to the communication terminal of the call. However, if the communication terminal of the call is not busy, the process proceeds to step 209 to form a call path and transmits caller information in step 211.

The control unit 10 checks the communication path between the transceiver 60 and the modem 50 in step 301 to check whether the system is busy. If the system is busy in step 301, the controller 10 proceeds to step 303 and periodically checks whether an alarm tone signal is received through the transceiver 60 and the modem 50. In this case, when the alarm sound signal is received, the controller 10 proceeds to step 305 to control the audio unit 70 to generate an alarm sound through the speaker SP of the audio unit 70. In this case, the user may know that a call has been received from a third party.

If the call is not in operation 301, the controller 10 proceeds to operation 306 to determine whether a call has been received. In this case, when the call is received, the controller 10 generates a ring tone through the ringer of the audio unit 70 in step 307, and proceeds to step 308 to check whether caller information is received. When the sender information is received in step 308, the control unit 10 demodulates through the transceiver 60 and the modem 50 in step 309, stores the demodulated information in the memory 20, and displays the caller information on the display unit 40. do. At this time, the caller information displayed on the display unit 40 is displayed a telephone number.

As described above, when a call is received from a third party while the user of the communication terminal is busy, there is a problem that interrupts the call by transmitting an alarm sound during the call.

In addition, even when the communication terminal receives the caller information in the standby state, only the phone number is displayed on the LCD, so that the user cannot know who the call was received from.

Accordingly, an object of the present invention is to display a caller's name and telephone number on a liquid crystal display when a call is received from a third party during a call or when a call is received in a waiting state. The present invention provides a method for displaying caller information including a caller name of a terminal.

In order to achieve the object of the present invention, the present invention provides a communication terminal having a display unit, and when a call is received from a third party when a communication path of the communication terminal is formed, caller information is displayed on the display unit to display the third party. It indicates that the call has been received from.

In order to achieve the other object of the present invention, the present invention provides a communication terminal having a display unit and a memory having a speed dialing table storing a plurality of telephone numbers and names for the telephone numbers, wherein caller information is stored through an antenna. When received, the telephone number of the caller information and the telephone number of the speed dialing table are compared with the telephone number of the caller information, and the name corresponding to the telephone number is displayed from the speed dialing table.

The controller 10 checks whether caller information is received through the transceiver 60 and the modem 50 in step 501. In this case, when the caller information is received, the controller 10 proceeds to step 503 and checks whether the system is busy. If the system is busy, the controller 10 proceeds to step 505 and stores caller information in the memory 20. After step 505, the controller 10 proceeds to step 509 and compares the phone number of the caller information stored in the memory 20 with the phone number stored in the speed dialing table of the memory 20 to determine whether there is the same phone number. Check it. In step 505, if there is the same phone number as the phone number of the caller information, the controller 10 proceeds to step 511, and reads the corresponding phone number and caller name from the address of the speed dialing number identical to the phone number of the caller information. It is displayed on the display part 40.

On the other hand, if the system is not busy in step 503, the control unit 10 proceeds to step 507 to generate a ring tone through the ringer of the audio unit 60, and forms a call path in step 508. After forming the call path in step 508, the controller 10 proceeds to step 505, and performs step 511 in step 505 described above.

As described above, the present invention has an advantage that a call is received from a third party without being disturbed by the call even if a call is received from the third party while the user of the communication terminal is busy.

Another advantage of the present invention is that by using the speed dialing function, the caller can know the caller's name when a call is received from a third party during a call or when a call is received in a waiting state.
