Abstract
In a multifunctional device, a packet analysis unit determines whether a received packet contributes to inhibition of a power saving mode, stores the time at which a packet is received and information indicating whether a packet is received during the power saving mode as information about the packet determined as contributing to the inhibition thereof, and calculates a period of access by a plurality of packets based on the stored information about the packet and a factor analysis unit classifies the access of which the calculated period is shorter than the waiting time of the power saving mode into an access inhibiting a shift to the power saving mode and classifies the access of which the period is not shorter than the waiting time of the power saving mode and which is made by the packet received during the power saving mode, into an access returning from the power saving mode.
