PROBLEM TO BE SOLVED: To achieve accurate frequency correction as compared with an AFC function that mobile communication terminal equipment has originally in the mobile communication terminal equipment. SOLUTION: The mobile communication terminal equipment 700 comprises a frequency correction unit 100, a GPS module 500, and a central processing unit 600 for connecting the frequency connection unit and the GPS module. The frequency correction unit 100 counts an IF signal obtained by allowing a signal from a base station to be subjected to frequency conversion, the central processing unit 600 converts the count value of the IF signal when the frequency correction unit 100 is in a lockup state to an actual count value offset, and the GPS module 500 counts a signal from an oscillator 105 and corrects the actual count value by the actual count value offset.
