1. A method in a wireless LAN system in a smart home environment, the method comprising:
obtaining, by a controller, first to third identifiers by scanning a quick response (QR) code of a controlee;
transmitting, by the controller, a generic advertisement service (GAS) initiation request message to the controlee; and
receiving, by the controller, a GAS initiation response message from the controlee, wherein the GAS initiation request message includes the first and second identifiers and an encrypted payload,
wherein the GAS initiation response message includes a decrypted payload when the first and second identifiers are the same as identifiers of the controlee,
wherein the controlee operates as a soft access point (AP) based on a connected home over Internet protocol (CHIP),
wherein the first to third identifiers are not included in a service set identifier (SSID) of the soft AP,
wherein the first identifier is a vendor identifier (VID),
wherein the second identifier is a product identifier (PID), and
wherein the third identifier is a device discriminator.
