    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 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.
