1. A method for dynamically changing a system configuration of a femto cell in a wireless communication system, the method comprising:
- monitoring, by the femto cell, downlink (DL) signals from one or more neighbor macro cells to detect the DL signals and cell IDs (identifiers) of the one or more neighbor macro cells included in respective DL signals in a stand-alone mode where the femto cell uses all available radio resources and operates independently without considering neighbor cells;
changing, by the femto cell, using a result of detection of the DL signals and the cell IDs of the one or more neighbor macro cells, a system configuration of the femto cell to avoid collision with the one or more neighbor macro cells, andbroadcasting, by the femto cell, the changed system configuration of the femto cell to a Mobile Station (MS),wherein changing the system configuration of the femto cell comprises;
detecting received power of the DL signals and candidate cell IDs to which the DL signals correspond, respectively,selecting a cell ID corresponding to a DL signal which has a lowest received power, from among the candidate cell IDs, as a cell ID for the femto cell, anddynamically changing the cell ID of the femto cell to the selected cell ID.

Abstract
The present invention relates to wireless communications system. More specifically, the present invention relates to a method in which a mobile station communicates with any desired node in a wireless communications system. This communications method comprises the steps of: transmitting upwards a first signal for searching for any desired node; receiving from the desired node a second signal indicating that a service can be provided to the mobile station, by way of response to the first signal; and carrying out a procedure for receiving the service from the desired node, wherein the desired node monitors the first signal in a sleep mode.
