Abstract: Disclosed is an access point, which is a registrant desiring to register with a multiple access point network. A wireless communication terminal comprises: a transmitting and receiving unit for transmitting and receiving a wireless signal; and a processor for processing the wireless signal. The processor receives a first device provisioning protocol (DPP) message from a controller of the multiple access point network when the access point is onboarding to the multiple access point network by using a DPP, obtains, from the first DPP message, information on a channel on which the DPP is performed, and transmits a second DPP message to the controller in the channel indicated by the information on the channel.
