The natural lighting system collects the sunlight and then reflects the collected sunlight to a target scanning area based on a sequential scanning mode, and includes at least one reflector disposed according to an optimum control angle for collecting the sunlight, and a sequential scanning drive continuously adjusting the reflector so as to allow the sunlight transferred from the reflector to be sequentially scanned on the target scanning area.

Abstract: A method for controlling data of base stations is disclosed. A base station management server generates and stores base station management data and mobile switching center access data. The base station management server receives requests of base station management data by a mobile terminal through a communication network. The base station management server transmits the base station management data to the mobile terminal in response to the request. It is more convenient when managers or operators manage and operate the base station management server because they do not need to physically move to view and/or modify the data of the base station.
