PROBLEM TO BE SOLVED: To provide a method for adapting the polling period of suspended service requests. SOLUTION: In this method, the polling period is adapted by polling a system to inspect the presence of suspended service requests, recording whether a suspended service request is present or not, determining whether the system device is in idle state or not on the basis of accumulated data. The system can select an energy saving mode until the device operation is reported by a signal, or an adjustable fixed time passed. By this adaptation mechanism, the period of timer interruption can be changed, the device interruption can be prohibited or permitted, and a variable (a minimum waiting time threshold, a minimum idling state threshold, etc.) used for determination of the idling state of the system can be changed. Accordingly, the system can save energy while keeping the performance and responsiveness of the system. COPYRIGHT: (C)2004,JPO&NCIPI
