摘要:
A method and apparatus are provided for generating a visible light signal according to an amount of data transmission in a first Visible Light Communication (VLC) device. The method includes determining a ratio of an amount of data that has been received from a second VLC device to a total amount of data to be received; determining a visible light signal pattern corresponding to the ratio; generating a visible light signal corresponding to the visible light signal pattern; and outputting the visible light signal.
摘要:
A method and an apparatus for managing personal health are provided. A gateway capable of communicating with a health device and a non-health device sets up a communication link with a communication device according to a first communication protocol, and determines whether the health device. When the communication device is determined as a health device, the gateway executes a health security algorithm which provides a higher level of security than a security of a security algorithm applied to the first communication protocol, and communicates with the health device by using the health security algorithm.
摘要:
An apparatus and a method for controlling a connection to a local area wireless communication network on the basis of a communication environment by means of a wireless terminal device are provided. To this end, the wireless terminal device collects information regarding a neighboring base station that constitutes a public communication network by means of a cell search, and determines whether it is possible to connect to a local area communication network on the basis of the collected information regarding the neighboring base station. If it is determined to be possible to connect to a local area communication network, the wireless terminal device makes an attempt to connect to a pre-registered wireless connection device on the basis of the collected information regarding the neighboring base station.
摘要:
A method and an apparatus for using a memory device are provided. A host device includes a transmitter that transmits data; a receiver that receives data; and a controller configured to receive configuration information of the memory device including the information related to the data stored in the one or more slots determined according to each vendor of the memory device, identify information related to predetermined data in the configuration data of the memory device, and receive the predetermined data from the memory device.
摘要:
A method and apparatus for supporting mobility of a mobile terminal in a Visible Light Communication (VLC) system. The method includes activating only necessary light sources for VLC considering the mobility of the mobile terminal, instead of using total light sources for VLC. Consequently, power consumption can be significantly reduced.
摘要:
A terminal communicating with at least one wireless communication device determines whether a first data is received from the at least one wireless communication device in a first mode, in which power is supplied to a display portion, determines whether a second data is received during a first time period from the time when the first data is received, and switches to a second mode in which the power supplied to the display portion is blocked according to whether the second data is received.
摘要:
A method and a lighting device for providing a Location Based Service (LBS) service providing a Location Based Service (LBS) based on Visible Light Communication (VLC) is provided. The method includes receiving, by at least one light source, data from a coordinator, the data including identification information of the at least one light source that corresponds to location information of the at least one light source, which is used by a terminal to identify a location of the at least one light source; and transmitting, by the at least one light source, the data to the terminal in a VLC signal.
