In general, personal mobile communication systems such as cellular phones and PDAs carry various types of digital wireless communication using 2 GHz bands while carrying one small portable terminal (about 100 to 150 g) each person. Refers to a service system. However, this definition of personal mobile communication refers to a concept that is independent of the technology or system used. By utilizing various technologies and network systems through liberalization and competition, the general public has a low price that does not differ from landline phones. In particular, the ultimate goal of personal mobile communication is to enable mobile communication in the city center or suburbs, and to communicate with a unique number of individuals rather than a number associated with a place or a vehicle such as a house or an office.

Therefore, in order to expand the concept of personal mobile communication as described above on a global scale and to receive service anywhere in the world by using a personal number independent of the network, ITU-T is promoting global standard personal communication (UPT). )to be.

Then, referring to FIG. 1, a mobile communication terminal which is an example of the conventional personal mobile communication as described above, a base station system for wirelessly processing a function signal transmitted from a plurality of terminals 70, for example, a call signal or an SMS message ( 71), an MSC 72 for controlling a call signal or an SMS message transmission function input through the base station system 71, and connected to the MSC 72 to provide an SMS message to the terminal 70. SMS message center 73 is included.

In addition, the terminal 70 is provided with a keypad device 74, as shown in Figure 2, the keypad device 74, the function key 77 and the numeric character key 78 is separated up and down and the Numeric character keys 78 also typically consist of three rows.

On the other hand, looking at the operation of the conventional mobile communication terminal as described above, if the user of the terminal 70, the user wants to transfer the information desired by, for example, the SMS message to the other terminal, the user of the terminal 70 is a terminal ( 70 selects the corresponding menu displayed on the LCD panel 75 through the menu function key 77 of the keypad 74 and then inputs the required character by operating the numeric character key 78. In this case, when the user of the terminal 70 wants to erase a certain letter by writing a text message incorrectly, the user of the terminal 70 deletes letters one by one using the erase key of the keypad 74 and then writes again. When the text input is completed through the above process, the user of the terminal 70 presses a transmission button together with the destination telephone number. Then, the terminal 70 transmits the text data input by the current user in an SMS message.

Accordingly, the SMS message signal of the terminal 70 is input to and stored in the SMS message center 73 via the base station system 71 and the MSC 72. Then, the SMS message center 73 checks the destination phone number of the input SMS message and transmits it to the MSC 72. Then, the MSC 72 transmits the SMS message signal transmitted from the SMS message center 73 to the counterpart mobile phone 76. The counterpart terminal 76 analyzes the received SMS message signal and displays the signal on the display.

However, in the keypad device of the conventional mobile communication terminal as described above, since one consonant and a vowel of alphanumeric keys are arranged in three columns, it is often mistyped when writing a text message. In addition, since the number keys and the function keys are separated from each other, there is a problem that the space utilization of the keypad is considerably lowered when the number of keys increases.

Accordingly, the present invention has been invented to solve the above problems, and since the consonants and vowels of the Hangul are arranged in a radial manner, the terminal user can intuitively write a text message using a key, thereby using the terminal accordingly. Its purpose is to provide a keypad device of a mobile communication terminal that can maximize convenience.

It is still another object of the present invention to provide a keypad device of a mobile communication terminal, in which a numeric key and a function key are integrated on the keypad, thereby significantly improving the space efficiency of the keypad device.
