Patent ID: 7912943

Claim:
An apparatus connectively coupled to a network, capable of shifting to a power saving mode when a predetermined condition is satisfied, wherein power consumption in the power saving mode is lower than in a normal state, the apparatus comprising: a storing unit for storing an address of a notification destination to which a mode shifting notification indicating that the apparatus shifts to the power saving mode when the apparatus shifts to the power saving mode is transmitted; a returning unit for returning a mode from the power saving mode to the normal state, in response to a predetermined access from a remote apparatus in the power saving mode; an adding unit configured to add an address of the remote apparatus having triggered the returning process performed by the returning unit, into the storing unit, as the address of the notification destination; and a notifying unit configured to transmit, to the address stored in the storing unit, the mode shifting notification indicating that the apparatus shifts to the power saving mode when the apparatus shifts to the power saving mode, in order to prevent the remote apparatus from performing the predetermined access, wherein the notifying unit transmits the mode shifting by a unicast when the mode shifting notification is transmitted to the remote apparatus having the address added by the adding unit, and the notifying unit transmits the mode shifting notification by a multicast when the mode shifting notification is transmitted to the remote apparatus.
