Abstract: An information processing apparatus includes a control section, and can temporarily pause at least some of its own functions. The control section of the information processing apparatus performs control for notifying, when at least some of its own functions are to be temporarily paused, a first apparatus that has a specific function of a function temporary pause period within which at least some of functions of the first apparatus are to be temporarily paused. Further, the control section of the information processing apparatus performs control for directing, when at least some of its own functions are to be temporarily paused, a second apparatus that does not have a specific function to restrain transmission. Power consumption of the information processing apparatus can be reduced.

Abstract: A communication control device includes a control unit. The control unit included in the communication control device performs control to notify an information processing device of a period for the information processing device to acquire information regarding a communication state in the information processing device. The control unit included in the communication control device further performs control to cause the information processing device to notify the information regarding the communication state acquired in the period and to determine a destination of a delivery confirmation request on the basis of the information regarding the communication state. Thereby, a destination of a delivery confirmation request can be appropriately determined.
