Claim:
A radio communication system comprising: a macro cell base station for performing radio communication with a mobile communication terminal to relay telephone conversation between mobile communication terminals, the macro cell base station covering an area of a macro cell; and a plurality of femtocell base stations installed in a plurality of buildings in the macro cell, each of the femtocell base stations covering an area narrower than the macro cell, wherein a broker femtocell base station that covers an area of an entrance is installed in the entrance of each of the buildings, and a broker identification code as an identification code is set in the broker femtocell base station, and an adjacent cell list and broker femtocell priority selection set information are set as system information of the macro cell, the adjacent cell list including an area identification code of each of adjacent macro cells and a broker identification code set in the broker femtocell base station, the broker femtocell priority selection set information being the information for preferentially selecting the broker femtocell base station, wherein a plurality of sub-femtocell base stations are installed in the building in addition to the broker femtocell base station, a sub-area identification code is set in each of the sub-femtocell base stations, the sub-area identification code being different from the broker identification code and different from a sub-area identification code of an adjacent femtocell, and an adjacent cell list and sub-femtocell priority selection set information are set as system information of the broker femtocell, the adjacent cell list including an area identification code of the macro cell including the broker femtocell and the sub-area identification code of the adjacent femtocell, the sub-femtocell priority selection set information being the information for preferentially selecting the sub-femtocell base station.
