An information processing apparatus according to the present invention is operated by at least switching between a first power state and a second power state in which its power consumption is less than that of the first power state. In a case where an event detected during a period from start to end of processing of making transition from the first power state to the second power state is a communication establishment event, the information processing apparatus causes a communication unit to transmit to a communication partner a notification for maintaining connection of communication in the second power state.
