Patent ID: 8004996

Claim:
A mobile communication apparatus comprising: a first processor; a second processor; an intermittent receiver that is operated using the first processor; and a timer processing unit that is operated using the first processor and the second processor and configured to determine a start time of an operation thereof by performing a time-out control based on a timer, wherein the timer processing unit sets the timer so that a time-out occurs at a given timing, to perform a first function to be started at the given timing, wherein the timer processing unit sets the timer so that a time-out occurs at a time when the intermittent receiver is operated, to perform a second function to be started at an arbitrary timing, and wherein a judgement is made by the timer processing unit to determine whether an operation using the second processor, for which a start time has been determined by the timer, is to be performed during operation of the intermittent receiver in order to start the operation using the second processor in accordance with a result of the judgement.
