Hereinafter, by the above-described configuration, a caller identification method using the foldable terminal external display halo color of the present invention will be described in detail with reference to the accompanying drawings.

In the folding terminal (closed) state, the small external display unit 34 displays the minimum operation information such as the operating area of the terminal, that is, the communication area or the communication area, time, etc. due to the radio wave reception state, In the open state, the main display unit 32 displays all operation information and text message information of the terminal.

In addition, the open state and the closed state of the folder are sensed by the key pad unit 20 and output to the processing unit 10 as a corresponding control signal.

A user of a folder type terminal classifies a caller's telephone number to call his terminal into groups and stores them in the EEPROM 18.

The storage is to input the caller's telephone number to the processing unit 10 by using the keypad 20, the classification of the group (Group) to be input is to distinguish according to the needs of the user, for example, a family telephone The numbers are classified and stored in the first group, the related telephone numbers in the workplace are classified in the second group, and the telephone numbers of friends are classified and stored in the third group.

When the caller calls, the mobile communication system transmits the calling signal to the called party and simultaneously sends the caller's telephone number by the caller identification service.

When calling the terminal from the caller, the mobile communication system wirelessly transmits the caller's telephone number to the terminal along with the call signal.

When the incoming call signal from the caller arrives as described above (S100), the terminal receives the received signal through the high frequency unit 50 and applies it to the processing unit 10 to output the incoming signal to the audio unit 40. The bell sounds.

The folder terminal, by the processing of the MSM 12, alerts the incoming state with the ring tone as described above, and determines whether the caller's telephone number is the same as the telephone number of the friendly group stored in the EEPROM 18 (S110). .

As a result of the determination (S110), when the telephone number is not registered in the friendly group of the EEPROM 18, the corresponding LED 36 of the external display unit 34 constituting the display unit 30 is driven to drive the external display unit ( 34 is selected or designated as the back light (S160), and the back light color is, for example, white so that the external display unit is back lit.

As a result of the friendship group determination (S110), in the case of the friendship group, the MSM 12 classifies again to determine whether it is the first to third groups stored in the EEPROM 18 (S120). In this case, by controlling the color LED 36 to emit green LEDs as an example (S130), the external display unit 34 is backlit to green, and the second If it is determined as a group to control the LED (36) to emit a yellow (Yellow) color LED (S140), if it is determined as a third group to control the LED (36) red color LED to emit light (S150).

The user of the folder terminal as described above identifies the halo color of the external display unit 34 to identify and confirm the callers of the first to third groups and the callers of the unfriendly group, and to determine whether to communicate with the caller ( S170).

As a result of the determination (S170), if the caller of the group not to communicate or the communication is not desired, the terminal terminates, and if the caller of the group to communicate and communicates, the folder is opened by opening a folder (Open). The signal is applied to the processing unit 10 from 20, and communication is performed by controlling the high frequency unit 50 by the processing of the MSM 12 (S180).

If the folder terminal user continues the communication (S190), the communication continues, and if the communication ends, the communication is terminated by closing the folder (S200).

When the communication is terminated as described above, the MSM 12 of the processing unit 10 controls the high frequency unit 50 to terminate the connection of the wireless channel and to display the corresponding operation information on the display unit 30.

Therefore, the technique of the present invention as described above, whether the sender is a friendly group by using the color of the back lighting that is attached to the outside of the foldable terminal, and displayed on the external display unit 34 made of a small LCD or It may be determined whether the group is unfriendly, and whether or not the communication proceeds.

The configuration of the present invention as described above, in the folder-type mobile communication terminal, there is an effect that can confirm the group of the caller by using the color of the external display that the color LED is backlit.

In addition, the terminal user has a convenient effect in use that can reduce the damage caused by the prank call.
