DATA COMMUNICATION APPARATUS FOR COMMUNICATING WITH EXTERNAL APPARATUS VIA NETWORK, CONTROL METHOD OF THE DATA COMMUNICATION APPARATUS, AND STORAGE MEDIUM

摘要

A communication apparatus communicating with an external apparatus via a relaying device is provided. The communication apparatus includes a communication unit configured to perform communication with the relaying device, and a control unit configured to reduce a communication speed of the communication unit to a lower speed if the communication apparatus is to be shifted from a first power mode to a second power mode in which power consumption is lower than that in the first power mode. The communication unit, if the communication apparatus shifts to the second power mode, transmits identification information of the communication apparatus to the relaying device using a first method, and after a predetermined time has passed, transmits the identification information to the relaying device by a second method.
