A Ubicell base station includes a Ubicell base station, one or more Ubicell core network elements, and an integrated management server. The Ubicell base identifies position information thereof using a GPS module, and at a time of setup, provides environment setting information including the position information thereof. Each Ubicell core network element, upon receiving environment setting information of an arbitrary Ubicell base station, generates an environment construction information file of the arbitrary Ubicell base station, registers the arbitrary Ubicell base station, and sends the environment construction information file to the arbitrary Ubicell base station. The integrated management server identifies the Ubicell core network element in a corresponding position based on the environment setting information, provided from the Ubicell base station, and provides the environment setting information of the Ubicell base station to the Ubicell core network element.
