摘要： A method for locating mobile terminals is provided. First, information of a home Public Land Mobile Network (PLMN) of a target mobile terminal, the location of which is to be determined, is checked in response to a location service request from a client. Then, information of a visited PLMN, where the target mobile terminal is currently located, is checked based on the checked information of the home PLMN. The home PLMN calculates location assistance information of the visited PLMN using specific location information of the visited PLMN. The location assistance information is transferred to the target mobile terminal. This allows location information of a mobile terminal to be obtained irrespective of the area or communication network where the mobile terminal is located. It is thus possible to locate a mobile terminal in an area where no location assistance information is provided.

摘要： An optical receiver for visible light communication includes a lens system for converging visible light for light communication and an optical filter for passing converged visible light to the optical receiver. A photoelectric transmission device detects data from visible light for light communication in a VLC system. An optical filter is positioned between the lens system and the photoelectric transmission device, the optical filter having a first film for transmitting visible light and a second film arranged/grown around the first film to transmit ultraviolet rays or infrared rays. A first optical detects data from visible light passing through the first film of the optical filter. A second optical detector detects the intensity of light transmitting the second film. The encoding, encoding rate or intensity of the optical transmitted signal can be adjusted in response to the detection of at least the second optical detector.
