MESSAGE EXCHANGING METHOD IN NAVIGATION SYSTEM USING VISIBLE LIGHT COMMUNICATION

摘要

A message exchanging method in a navigation system using visible light communication is provided to exchange the message between a terminal and a navigation server by using the visible communication in a large-scale building which cannot receive a GPS(Global Positioning System) signal. A navigation map server(401) stores the location of the building mapping data and each lamp. The server receives the destination information from a mobile terminal(406) through lamp by using the power line communication. According to server is the navigation algorithm and mapping data, the optimal path to the destination location is produced and transmits the optimum path to the mobile terminal.
