A radio communication apparatus to be changed in function by software, when downloading software from a download server, first downloads software limited in operation and then configures a software radio section. After the configuration and the operation confirmation have been normally completed, execution-allowing key information is requested and received. Using it, reconfiguration is carried out in part thereby enabling all the operations. Accordingly, it is possible to safely carry out a download and a setting update of software to the radio communication apparatus.
