<P>PROBLEM TO BE SOLVED: To obtain a cable utilization system which can reduce the power consumption of a radio communication terminal even when using an external antenna. <P>SOLUTION: The cable utilization system, which is provided with the radio communication terminal 10 making a communication with a radio base station through a main body antenna 11 in the case of non-connection of a cable 20 to a connector prepared in a main body and switching a signal input/output route from the side of the main body antenna 11 to the side of the cable 20 in the case of connection of the cable 20 to the connector, is provided with: the radio conversion device 30; and the incoming call detector 50. The radio conversion device 20 is connected to the radio communication terminal 10 by the cable 20 and is connected to the radio base station by a cable and converts signals from the radio communication terminal 10 to signals on the cable and converts radio signals from the radio base station to signals which can be processed in the radio communication terminal 10. The incoming call detector detects call termination from the radio base station on the basis of a registered terminal number of the radio communication terminal 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
