Abstract: Disclosed herein are a sound sleep assistance apparatus, a sound sleep assistance method, and a sound sleep assistance system. According to an embodiment, there is provided a sound sleep assistance apparatus for assisting the sound sleep of a user by communicating with a sleep pad, the sound sleep assistance apparatus including: a communication interface configured to communicate with the sleep pad that acquires the physiological index information of the user while the user lies down; and a controller configured to determine the sleep stage of the user based on the physiological index information, and to provide a sound source corresponding to the determined sleep stage.

Abstract: The present disclosure relates to visible light communication (VLC) data forwarding between a wearable device and a host device. The wearable device having a VLC receiver can receive a visible light communication signal from a VLC transmitter and deliver or forward a data packet demodulated from the visible light communication signal to the host device paired therewith.

Abstract: A visible light communication device management method and apparatus are disclosed. According to one aspect of the present disclosure, an object of the present disclosure is to provide an apparatus and method for checking and managing a membership of a terminal, such as a communication state and a location of a terminal managed by the server.

Abstract: Disclosed are a method and apparatus for registering visible light communication devices and combining a visible light communication signal and a wireless communication signal. It is an object of the present disclosure to provide a visible light communication device registration method in which a lighting device allows collective registration of the lighting device and a terminal as the terminal transmits data to a light using wireless communication.
