Wireless communication system, mobile station, wireless base station and communication method

摘要

A wireless communication system having a first wireless base station or BS (11a) such as a macro eNB, and a second wireless base station or BS (15) such as a Home eNB defining a cell within a cell of the first wireless BS (11a) and usable by a specified mobile station. The wireless communication system includes means registering first identifiers as identifiers of the first BS (11a) and a second identifier as an identifier of the second BS (15) in the specified mobile station in advance. The wireless communication system further includes means for transmitting first information to the second BS (15) when an identifier of a present cell is other than the first and second identifiers, and transmitting second information to the second BS (15) when the identifier of the present cell is the first or second identifier, and controlling an operation of the second BS (15) based on the received first or second information. The system may be used to reduce power consumption of a Home eNB when no mobile station capable of using it is present.
