Abstract

A method by which a first wireless device performs a wireless connection in a wireless LAN system, according to one embodiment, comprises the steps of: receiving an advertising packet from a second wireless device through a primary channel, wherein the advertising packet includes first information for specifying a Wi-Fi service for the advertising packet and second information linked to the existence of additional data, and the first information is set as a first value linked to a DPP procedure or a second value linked to a NAN procedure; establishing a BLE-based connection with the second wireless device in order to receive the additional data; transmitting, to a second wireless terminal, a request packet for requesting additional data; and receiving, from the second wireless device, a response packet, including the additional data, as a response to the request packet, wherein the additional data is associated with DPP bootstrap URI information of the second wireless device.

Dependent claims

A method for establishing a wireless connection in a wireless Local Area Network (LAN) system, the method comprising:

receiving, by a first wireless device, an advertising packet from a second wireless device,
wherein the advertising packet is configured based on a Transport Discovery Service (TDS) packet, and
wherein the TDS packet includes an Organization identifier (ID) field and an Organization Data field, the Organization ID field includes information on an organization related to the TDS packet, a pre-defined value of the Organization ID field is used for identifying Wi-Fi Alliance (WFA), the Organization Data field includes a header field and a service information field, a pre-defined value of the header field is used for identifying that the service information field is used for a Device Provisioning Protocol (DPP);
after receiving the advertising packet, establishing, by the first wireless device, a Bluetooth Low Energy (BLE) based connection with the second wireless device for the DPP;
transmitting, by the first wireless device, a request packet requesting additional data related to the DPP to the second wireless device;
and
receiving, by the first wireless device, a response packet including the additional data from the second wireless device as a response to the request packet,
wherein the additional data is related to DPP Bootstrap Uniform Resource Identifier (URI) information of the second wireless device.
