In the present invention for achieving the above object, a separate type mobile communication terminal demodulates an image signal among radio frequency signals received through an antenna, and transmits the demodulated image signal through a first interface, and the first body. And a second body for receiving the image signal provided from the second interface and outputting the image signal to the LCD for viewing by the user.

Further, in order to achieve the above object, in the present invention, a first body for demodulating an image signal among radio frequency signals received through an antenna and transmitting the demodulated image signal through a first interface, and an image provided from the first body. A communication method of a separate mobile communication terminal, which is separated into a second body that receives a signal through a second interface and outputs it to the LCD for viewing by a user, includes a process of turning on the power of the mobile communication terminal and turning on the power. Displaying the available state generated by the LCD through the LCD in the second body, and when a call button is pressed by the keypad in the first body, connecting a call path between the calling party and the called party; The process of performing a voice call while the user confirms the called party by outputting the image signal transmitted through the furnace to the LCD in the second body via the first and second interfaces. Characterized in that it also.

Hereinafter, a plurality of embodiments of the present invention may exist, and a preferred embodiment will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate the objects, features and advantages of the present invention through this embodiment.

1 is a schematic block diagram of a detachable mobile communication terminal according to the present invention, and includes a first main body 101 and a second main body 103.

The first body 101 includes a tuner unit 1011, a signal processing unit 1013, a control unit 1015, a keypad 1017, a battery unit 1019, and an interface unit 1021. .

The tuner unit 1011 converts the radio frequency signal received through the antenna S1 into a baseband signal and transmits the signal to the signal processor 1013.

The signal processor 1013 demodulates an audio signal of the signals transmitted through the tuner unit 1011 and transmits the demodulated signal to the controller 1015 and provides an image signal to the second body 103 through the interface unit 1021, or The voice signal transmitted from the controller 1015 is modulated and transmitted to the tuner unit 1011.

The control unit 1015 operates according to the information transmitted from the keypad 1015, and the control unit 1015 controls the voice signal processed by the signal processing unit 1013 so that the caller / incoming user can make a voice call through a speaker (not shown). To control.

The keypad 1017 transfers user's information directly to the controller 1015.

The battery unit 1019 is for driving the first body 101 and uses a general alkaline battery or a rechargeable battery.

The interface unit 1021 is one of a slide type connector communication, a Bluetooth communication, and an infrared communication method. The interface unit 1021 is a block for communicating with the second main body 103, and the image signal of the first main body 101 has been described. It transmits to the interface unit 1033 in the second body 103 through either.

The second body 103 includes a battery portion 1031, an interface portion 1033, and an LCD portion 1035.

The battery unit 1031 is for driving the second body 103 and uses a general alkaline dry cell or a rechargeable battery.

The interface unit 1033 is one of a slide type connector communication, a Bluetooth communication, or an infrared (IrDA) communication method, and is a block for communicating with the first body 101. The interface unit 1021 in the first body 101 is provided. Receives an image signal transmitted from and transmits to the LCD unit 1035.

The LCD unit 1035 outputs an image signal received through the interface unit 1033 for the user to see.

Therefore, the separate type mobile communication terminal according to the present embodiment is formed by separating one mobile communication terminal into a main body 101 having a call function and a numeric keypad and a display body 103 for outputting a screen. By transmitting the video signal through the interface, you can talk freely while watching a video in the video call, and also maximize the advantages of multi-tasking to enjoy the convenience of the call.

Next, a description will be given of the communication process of the separate type mobile communication terminal in the present embodiment having the configuration as described above.

2 is a flowchart illustrating a communication method of a detachable mobile communication terminal according to a preferred embodiment of the present invention.

When the user turns on the power of the mobile communication terminal (S201) and the communication service is available between interfaces after the initialization process (S203). When the first body 101 informs the second body 103 that the mobile terminal is currently available, the LCD unit 1035 indicates that the mobile terminal is currently available (S205).

In addition, when the user of the separate mobile communication terminal operates the keypad of the first body 1017 to make a call and then presses the called party's telephone number and then presses the call button S207, the controller 1015 makes a call with the base station not shown based on the call. Attempts to connect the call path with the called party (S209).

In this case, in the case of a separate type mobile communication terminal for a video call, when the video information and the voice information of the called user are received through the tuner unit 1011 (S211) and provided through the demodulation process of the signal processing unit 1013, The user outputs the image information to the LCD unit 1035 in the second body 103 via the interface units 1021 and 1033 connected between the first body 101 and the second body 103 (S213). While confirming, the voice call may be performed (S215).

Here, each of the first body 101 and the second body 103 has independent battery units 1019 and 1031.

Therefore, in the present invention, the detachable mobile communication terminal is formed by separating one mobile communication terminal into a main body having a call function and a numeric keypad and a display main body for screen output, and by communicating a signal through the interface between the two main bodies, If you are in a video call, you can talk freely while watching videos, and also maximize the benefits of multitasking so that you can enjoy the convenience of the call as much as possible.

As described above, in the present invention, the detachable mobile communication terminal is formed by separating one mobile communication terminal into a main body having a call function and a numeric keypad and a display main body for outputting a screen. By communicating the signal through the video call, the user can freely talk while watching a video, and also maximizes the advantages of multi-tasking to enjoy the convenience of the call as much as possible.
