<p>PROBLEM TO BE SOLVED: To provide a technique for efficiently using a frequency band used for radio communication while avoiding interference for a radio communication device which is adapted to a plurality of radio communication systems and performs radio communication with a plurality of frequency bands.SOLUTION: A radio communication device includes a transmission/reception part adaptively to a plurality of communication systems, which independently perform radio communication. When a frequency band used by a first communication system such as PHS is close to a frequency band used by a second communication system such as 3G/LTE, the second communication system may interfere with communication of the first communication system. The radio communication device determines whether the second communication system uses the frequency band which may interfere with communication of the first communication system when termination by the first communication system is detected, and searches for another usable band if the second communication system uses the frequency band which may interfere with the communication of the first communication system. When the second communication system can use the searched band, the radio communication device makes a transition to the band and performs termination processing of the first communication system.</p> |
