Abstract
An electronic apparatus includes a plurality of communication units including a first communication unit which communicates via a first communication network and a second communication unit which communicates via a second communication network. The electronic apparatus acquires presence information indicating a communication state of a communication apparatus from a presence server managing a communication state of a communication apparatus on a communication network, via at least one communication network. The electronic apparatus acquires presence information of an alternative communication apparatus being as a communication apparatus which communicates via the second communication network in place of the second communication unit included in itself. The electronic apparatus determines as to whether the alternate communication apparatus is in an online state, based on the acquired presence information. The electronic apparatus suppresses electric power to be consumed by the second communication unit, when the alternate communication apparatus is in an online state.
