3 is a flowchart illustrating a method for automatically displaying local number of mobile communication terminals according to an exemplary embodiment of the present invention. Hereinafter, an operation according to the present invention will be described with reference to the configuration of FIGS. 1 and 2.

First, in step 301, the controller 10 checks whether a power key is input to turn on the power. At this time, when the power is "on", the control unit 10 checks the synchronization channel, detects the synchronization frame transmitted from the radio base station 106 of FIG. 1, and acquires the system. If the system is captured, the controller 10 proceeds to step 303 and sends a registration message through the access channel. The registration message includes an SID which is a base station controller identification number of the home system of the mobile communication terminal 108, an NID which is a radio base station identification number, and an electronic serial number (ESN). The mobile switching center 103 receives the registration message transmitted from the mobile communication terminal 108 through the wireless base station 106 and the base station controller 104 to perform subscriber authentication. At this time, the mobile switching center 103 detects the link identification number of the registration message and compares it with its SID to determine whether the mobile communication terminal 108 is in a roaming state. The mobile switching center 103 transmits a registration response message including a link identification number which is an identification number of the base station controller 104 and the radio base station 106 forming a link with the mobile communication terminal 108 through a base station controller 104 and the radio base station 106 in the form of a radio signal. To the mobile communication terminal.

In step 305, the controller 10 of the mobile communication terminal 108 checks whether a registration response message is received from the wireless base station 106 through the registration response message detector 80. In this case, when the registration response message is input to the registration response message detector 80 through the antenna ANT, the RF unit 50, the baseband analog unit 60, and the signal processor 70, the controller 10 controls the registration response message detector 80 in step 307. Detect link identification number. If the link identification numbers of the base station controller 104 and the radio base station 106 are detected, the controller 10 proceeds to step 309 and compares all NIDs and SIDs in the area code table of the memory 20 to check whether there is the same. If there is the same NID and SID in the area code table, the controller 10 reads an area code corresponding to the NID and SID of the area code table and sets the area code as an automatic area code in step 311.

After the automatic area code is set, the controller 10 checks whether a flip open is detected in step 313. If the flip is opened during the inspection, the controller 10 displays the area code set in step 315 on the display unit 40. If the automatic area code is automatically set and then the power is "off" and then "on" again, the area code is automatically displayed on the display unit 40.

In addition, Figure 3 shows the process of registering the automatic area code setting when the power is "on", but when the mobile terminal 108 registers the power "off" registered to the mobile switching center 103, timer-based registration, zone-based registration, parameter change It can be set by registration or the like.

As described above, the present invention has an advantage of providing convenience to the user since the user does not need to input the area code even when the area code moves to another area.
