Now, a preferred embodiment of the present invention will be described in detail with reference to the drawings of FIG. 2.

Figure 2 is an internal block diagram of a mobile phone provided with a dialing function using the site key of the present invention.

First, the controller 110 may control the overall operation of the digital mobile communication terminal and realize it as a one chip microprocessor.

The memory 120 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 110.

The key input unit 130 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 110.

The display unit 140 includes a liquid crystal display unit for displaying various types of information, and is controlled by the controller 110 and receives and displays key data generated by the key input unit 130 and various information signals of the controller 110.

The display unit 140 may be implemented as a liquid crystal display (LCD) and is provided inside and outside, respectively. The audio unit 170 processes voice signals input and output through the speaker SP and the microphone MIC. In addition, when a ring signal is generated from the base station, the audio unit 170 detects the ring signal through the transceiver 160 and the modem 150 and transmits a ring tone through a ringer.

The modem 150 demodulates and demodulates data input and output to the controller 110 and modulates and demodulates a voice signal input and output to the audio unit 170. The transceiver 160 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.

Now, a method for making a call using a site key according to an embodiment of the present invention will be described with reference to FIG. 2.

First, when the user clicks the menu button, the controller 110 provides the display unit 140 with a higher menu such as a phone book, message management, and alarm setting.

When the user selects the phone book menu from the provided upper menu, the sub menu provides sub menus such as recent caller ID, recent caller ID, phone number search, phone number registration, simple phone number registration, and side key setting.

In this case, the user who wants to use the quick dialing using the side key selects a menu for registering a quick phone number, and accordingly, the controller 110 provides a quick phone number registration window to the user.

The user enters a phone number, a name, etc., and when the completion key is pressed, the phone number entered as a simple phone number is registered. At this time, the number of registerable phone numbers is within 10, to facilitate scrolling.

On the other hand, a user who wants to use the side key as a simple telephone key should switch the side key from the auto answer function to the easy dialing function using the side key setting menu.

That is, when the user selects the side key setting menu, the control unit 110 provides the site key setting window to the user and functions the side key as an automatic answering function key and a simple dialing function key according to the selection.

As such, if the user makes a long press and the side key is pressed while the side key is changed to perform the easy call function, the controller 110 controls the external liquid crystal display through the display unit 140. Display the first telephone number in the speed dial list with the name.

When a short side key signal is input, the user dials a list of easy-dial phone numbers, and when a long site key signal is input, the user dials the selected phone number automatically.

At this time, when the other party answers the call while the folder is closed, howling may occur, so the microphone is turned off when the folder is closed.

When the other party answers the call, the external LCD displays the message "The phone is connected" so that the user can open the folder and talk.

However, if the other party does not answer the call, pressing the answering machine key terminates the call connection.

3 is a flowchart illustrating a process of setting up a quick dial list according to an embodiment of the present invention.

Referring to the drawing, first, when a simple call setup menu selection key key signal is input from the key input unit (step S110), the control unit provides a simple call setup window (step S112).

After that, when the user enters the telephone number and name (step S114), the telephone number and name are added to the simple dialing list (step S116). Instead of entering a phone number and name, it is also possible to select a phone number and name already stored in the phone book and add it to the speed dial list.

4 is a diagram illustrating a process of changing a side key function used in the present invention.

Referring to the drawing, first, when the site key setting menu selection key key signal is input from the key input unit (step S120), a side key function change window is provided (step S122).

Subsequently, when the user selects the change of the side key to the easy dialing function key (step S124), the side key function is changed to the simple dialing function key (step S126).

At this time, if the function of the side key is already set as a simple dialing function key, there is no need to change, and the process of changing the side key set as the quick dialing function key to an auto answer key is the same as described above.

Of course, this procedure is not necessary if a separate dialing key is provided.

5 is a flowchart of a method for making a simple call according to an embodiment of the present invention.

Referring to the drawing, when the side key signal is input while the side key is set to the easy dialing function key (step S210), the first telephone number of the quick dial list is displayed on the external display window (step S212).

After that, it is determined whether a long or short side key signal is input, and if a short key signal is input, the phone number is scrolled (step S216) to display the next phone number on the quick dial list on an external display window.

If the long side key signal is input, automatic dialing is performed to the selected telephone number (step S218).

Thereafter, if the call is not connected, the user ends the call attempt by pressing a side key, and if the call is connected, the controller displays a call connection message on the external display window (step S222). You can also generate a sound effect with the call connection message.

Next, if the folder is opened by detecting whether the folder is opened, the microphone is turned on (step S226) to allow a call.

Although the present invention has been described in detail with reference to preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims.

According to the present invention as described above, there is an effect to facilitate the user by making a phone call without opening the folder by using the side key in the existing folder-type mobile phone.
