<P>PROBLEM TO BE SOLVED: To provide a mobile communication terminal which can contribute to improvement in stability of communication by: detecting intrusion and escape into and from a femto cell to perform cell search processing; and detecting a femto cell base station. <P>SOLUTION: The mobile communication terminal includes: an antenna which performs transmission/reception of a radio signal; a communication means for establishing a radio communication line with a base station via the antenna to make communication; a measurement means for measuring received power intensity of the radio signal to be received by the antenna as first received power intensity, measuring received power intensity of a radio signal to be transmitted from the base station in which the communication means establishes the radio communication line as second received power intensity, and measuring received power intensity of a noise signal as third received power intensity; and a cell search processing means for detecting the base station via the communication means when the first received power intensity exceeds a predetermined value, and a ratio between the second received power intensity and the third received power intensity is less than the predetermined value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
