ABSTRACT:
A mobile communication terminal, in which a user of the mobile communication terminal can designate handover among plural communication systems, is provided. The mobile communication terminal provides radio sections for different communication systems, which establish, connect, and disconnect radio lines, and measure communication quality at the communication systems, a controller, which controls each of the radio sections so that each of the radio sections establishes, connects, and disconnects a radio line, and measures the communication quality at each of the communication systems, and also controls handover operation among the communication systems by changing the operation of the radio sections, and an operating section which exchanges information with a user of the mobile communication terminal.
