ABSTRACT:
A wireless processing section has modulation/demodulation circuits which contain communication protocols used for a plurality of communication systems. A communication control section performs an entering idle state process according to a selected communication mode by a communication processing selection section and executes an entering idle state process by switching communication modes until an entering idle state process is successful. Subsequently, when an entering idle state process is successful, a maximum number of origination retry attempts is determined corresponding to a required time interval until completion of that entering idle state process. Specifically, the maximum number of origination retry attempts is decreased to the extent that the time interval until an entering idle state process completion becomes longer. The communication control section performs retries fore only the determined maximum number of origination retry count attempts when connection failed in an origination process.
