In general, mobile phones in these mobile communication systems divide the service area into hexagonal cells of several km to several ten kilometers in diameter in North America in the early 1980s, and then repeatedly use the same frequency channel in geographically separated cells. According to the first commercialization of a cellular phone (cellular-phone) that implements the radio channel switching function between cells has grown rapidly. In recent years, however, the universal mobile telecommunication system is capable of transmitting "third generation", broadband packet-based text, digitized voice or video, and multimedia data at a high speed of 2 Mbps or higher, regardless of where the mobile or computer users are anywhere in the world. Networks are developed to provide consistent services. At this time, the UMTS network allows computer and telephone users to continuously access the Internet while traveling and have the same performance regardless of where they are traveling. Users will use this UMTS service through a combination of terrestrial radio and satellite transmission technology.

Then, referring to the conventional mobile communication system as described above with reference to Fig. 1, from the terminal (70, 71) and the terminal (70, 71) for executing a voice call through the session setup procedure by sending a call signal during the movement The base station 72 processes the session procedure signal transmitted or transmits an incoming call requested from an external system to the terminals 70 and 71 and processes channel information with the terminals 70 and 71 in the sector through a paging channel. do.

Meanwhile, referring to the operation of the conventional mobile communication system as described above, first, when power is applied to the terminal 70, the terminal 70 proceeds to an initialization state to form necessary information in the internal memory and read each parameter. Then, the terminal 70 receives the Gener page msg signal transmitted from the base station 72 after executing the initialization process and then transmits the page response msg signal in response. In addition, the terminal 70 sequentially receives channel assign msg, service connect, and alert msg signals from the base station 72 after the process and proceeds to the standby state. In this case, the terminal 70 receives a traffic channel assignment from the base station 72 and then receives an alert msg signal and rings the reception bell to the user.

In this case, when the user of the terminal 70 inputs a telephone number signal to connect a call, the terminal 70 receives a call resource by performing a session procedure through the neighboring base station 72 and then the other terminal 71. Make a call with.

Since the user of the mobile phone can not use the display function to inform the user's preferences at all, the use of the terminal is inconvenient accordingly, and even if the function is provided, the display is only displayed on the LCD panel. Therefore, the terminal user can not easily determine the direction of the terminal from the outside, there was a problem that significantly reduces the user convenience accordingly.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems. Since the direction information of the terminal displayed on the keypad can be easily checked with the naked eye, this information can be easily used when executing a desired menu on the LCD. Therefore, it is an object of the present invention to provide a direction display device and a control method of the mobile communication terminal using the keypad to maximize the user convenience accordingly.
