VISIBLE LIGHT COMMUNICATIONS METHOD AND A SYSTEM THEREOF FOR PREVENTING THE WASTE OF RESOURCES BY EFFICIENTLY USING THE LIGHT SOURCE OF A VISIBLE LIGHT COMMUNICATIONS SYSTEM

摘要

PURPOSE: A visible light communications method and a system thereof for preventing the waste of resources by efficiently using the light source of a visible light communications system are provided to supply various services to each user by supplying visible light communication service by using a plurality of light sources.;CONSTITUTION: One or more light source included in one cell is determined and grouped if a user service request generates(401). Light sources are mapped to one cell(403). A time slot is allocated(405). Data related to the user service is transmitted to each visible light communications terminal by using the time slot(407). A visible light communications method efficiently uses the light source of a visible light communications system.;COPYRIGHT KIPO 2010
