<p>It is possible to provide a radio communication terminal, a radio communication terminal communication control method, and a radio communication system capable of effectively capturing a communication system when a transmission operation is performed even if judgment of out-of-cell is made. The radio communication terminal (10) includes a control unit (18) which stores in a storage unit (17) information specifying a communication system captured among a plurality of communication systems as a successful history.If a communication start is requested in the state judged to be an out-of-cell state, the communication system specified by the successful history is made to be an object to be captured when the location before transition to the out-of-cell state is judged to be in an area having no roaming while a communication unit (11) tries to capture the communication system specified by the successful history and a communication system not specified by the successful history among a plurality of communication systems when the location is judged to be in an area having roaming. If the capture by the communication unit (11) is successful, a communication is started.</p> |
