Abstract

An RF communication control system for executing the process of transmitting and receiving an RF signal through an RF control circuit unit and digitally processing the data contained in the RF signal through a baseband circuit unit, is disclosed. The baseband circuit unit includes a setting parameter holder for holding the setting parameter of each of a plurality of RF control elements, a setting parameter determining unit for determining, when the RF control element connected to the baseband circuit unit is switched to a second RF control element, the setting parameter to be used by the second RF control element after switching based on the setting information supplied from an external source, and a setting parameter selection processing unit for selecting the setting parameter corresponding to the second RF control element from the setting parameter holder based on the determined result and sending out the setting parameter to the second RF control element. An RF communication control method using the RF communication control system and a computer-readable storage medium to store the program for executing the RF communication control method by the computer, are also disclosed.
