摘要： A method and apparatus for arranging communication links in visible light communication increases the user visibility of the system. The method includes the steps of: (a) synchronizing, by a visible light communication (VLC) exchange identification (XID) frame, (b) transmission timing of a primary device and a secondary device in an allocated time slot, and securing time so as to allow the primary device and the secondary device to perform an operation required for transmitting data; (c) transmitting an XID command frame from the primary to the secondary device and (d) transmitting an XID response frame from the secondary receiving the XID command frame to the primary; and (e) filling remaining space of the allocated time slot with a visibility field so as to increase visibility of the remaining space of the allocated time slot after receiving the XID command frame or the XID response frame.

摘要： A method and apparatus for performing a navigation service in a mobile terminal is provided. Map information and an IDentification (ID) of an information spot, which is connected to a map server, are received from the information spot. A current position is determined. The map information and the current position are displayed A destination input by a user is received. An optimal path from the current position to the destination is calculated and displayed by using the map information. When the mobile terminal receives an ID of a general spot from the general spot, a current position of the mobile terminal is re-determined. When the re-determined current position is on the optimal path, the optimal path is updated and the updated optimal path from the re-determined current position to the destination is displayed.

摘要： A system and method for continuing a communication link while maintaining visibility in visible light communication. A frame is transmitted by a sender for establishing a communication link before data transmission to a receiver by a sender. A receiver sends a response frame that reports on establishment of the communication link prior to data transmission by the sender. A data frame containing information is transmitted by the sender to the receiver. An acknowledgment frame is transmitted to the sender in response to the data frame. A disconnect frame is transmitted by the sender which is acknowledged by the receiver. A visible sequence is transmitted during a time period when the sender and the receiver do not transmit respective frames for communication to maintain visibility between two devices that may be communicating otherwise by, for example, infrared communication.
