ABSTRACT:
In response to the occurrence of an application event in a portable terminal with the communication function that has an application control CPU (ACPU) and a communication control CPU (CCPU), the operation of a control target unit, which is under control of a CCPU and which operates at an intermittent reception time, is detected. During the operation period of the control target unit, an ACPU sends a transmission request to the CCPU to start the CCPU. When the CCPU is in the sleep state in the intermittent reception cycle, the CCPU is not started by the ACPU.
