Proposed is a method and device for generating a user identification model on the basis of wireless sensing in a wireless LAN system. Specifically, a user identification apparatus discovers a PED and acquires identification information about the PED. The user identification apparatus collects data and pre-processes the collected data on the basis of the identification information about the PED. The user identification apparatus generates a user identification model by learning the pre-processed data.

The present disclosure relates to a method for a third device to perform device authentication in a wireless communication system, and an apparatus for same, which comprises: forming a connection with a first device for being provided with a credential token based on at least one user account related to a specific user; receiving a first message including the credential token; broadcasting an advertisement message including a token identifier (ID) based on the credential token; and forming a connection with a second device through the device authentication of the second device based on the token ID, wherein the success of the device authentication is determined based on whether (i) at least one user account related to the specific user and identified based on the token ID matches (ii) at least one user account among one or more user accounts related to an account-based pairing filter set in the second device.

Method for managing user account using near-field communication in wireless communication system, and apparatus for same

In a wireless communication system supporting Bluetooth communication, an in-flight entertainment (IFE) device may perform scanning for a first Bluetooth low energy (BLE) device and a first Bluetooth basic rate/enhanced data rate (BR/EDR) device. The scanning for the first BLE device and the first Bluetooth BR/EDR device may be performed in a time division (TD) manner performed in different time intervals. The scanning for the first BLE device may include a step of receiving a first advertising signal of the first BLE device. The scanning for the first Bluetooth BR/EDR device may include a step of transmitting a scan signal and receiving a first scan response signal from the first Bluetooth BR/EDR device, by the IFE device.

An indoor air quality control method using an intelligent air cleaner is disclosed. An indoor air quality control method using an intelligent air cleaner according to an embodiment of the present invention can predict indoor dust concentration progress on the basis of output values of a learning model having received dust concentration data as input values when the dust concentration data of an indoor place where the air cleaner is located is received from the air cleaner, and determine whether ventilation is required by comparing the predicted progress with outside dust concentration data received from the Meteorological Administration server. Accordingly, indoor dust concentration changes can be predicted and an appropriate ventilation time can be recommended. The intelligent air cleaner and the indoor air quality control method using the same of the present invention can be associated with artificial intelligence modules, devices related with the 5G service, and the like.
