DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

1 is an internal configuration diagram of a mobile communication terminal according to a preferred embodiment of the present invention.

Referring to FIG. 1, the GPS receiver 10 receives location information from three or more satellites at regular intervals and transmits the same to the controller 12, and the data transmitter / receiver 16 transmits a voice transmitted from a server of a mobile communication service company. Receives the image data and transmits it to the control unit 12, and conversely transmits the audio or video data to the mobile communication service company. The memory 14 stores location information, signal strength information, and the like of the mobile communication terminal. The image processor 19 processes the image signal to be displayed on the screen of the mobile communication terminal, and the audio processor 20 processes the audio signal to be output through a speaker or the like. On the other hand, the user input unit 18 outputs a predetermined command signal to the control unit 18 in response to the user's operation to control the overall operation of the mobile communication terminal.

Now, detailed functions of the components of the mobile communication terminal for achieving the present invention will be described. The controller 12 checks whether the strength of the signal input to the data transceiver 16 is smaller than a predetermined threshold previously stored in the memory 14. If small, the corresponding location information is received from the GPS receiver 10 and stored in the memory 14 together with the signal strength, and a message indicating that the current reception sensitivity is poor is outputted to the display screen (or speaker). do. In addition, the controller 12 stores the strength and location information of the signal currently received at predetermined intervals in the memory 12. In addition, the control unit 12 transmits the location information with poor reception sensitivity and the strength of the received signal to the server side of the mobile communication service company through the data transmission / reception unit 16.

 Now, the detailed operation procedure of the mobile communication terminal having such a configuration will be described in more detail.

Referring to FIG. 2, when the 'random reception location information storage function' is set in response to a predetermined command signal input from the user input unit 18 (step 10), the control unit 12 returns to the data transmission / reception unit 16. It is checked whether the intensity of the received signal is less than a predetermined threshold previously stored in the memory 14 for a period of time (step 12). As a result of the check, when the strength of the received signal is smaller than the threshold value, the current position information is received from the GPS receiver 10 (step 14). Next, if it is set to the 'auto save mode' (YES in step 16), the strength and position information of the received signal is immediately stored in the memory 14 (step 19). If not in the 'automatic storage mode' after the storage whether or not to confirm the step (step 17), the strength and position information of the received signal is stored in the memory.
