An apparatus and method for automatically searching for a low-power Base Station (BS) supporting access of a registered user in a mobile communication system includes a method of performing automatic search on a Closed Subscriber Group (CSG) cell by a User Equipment (UE). The method includes determining by the UE whether automatic search needs to be performed on the CSG cell. The method also includes, if it is determined that automatic search does not need to be performed on the CSG cell, turning off by the UE a CSG cell automatic search function of the UE by emptying a first white list including CSG Identifiers of accessible CSG cells.

1. A method to perform an automatic search on a Closed Subscriber Group (CSG) cell by a User Equipment (UE), the method comprising:
determining, by the UE, whether the automatic search needs to be performed on the CSG cell; when the automatic search does not need to be performed on the CSG cell, turning off, by the UE, a CSG cell automatic search function of the UE by emptying a first white list including CSG IDentifiers (IDs) of accessible CSG cells; when the automatic search needs to be performed on the CSG cell, determining, by the UE, whether the first white list is empty; and when the first white list is empty, turning on, by the UE, the CSG cell automatic search function of the UE by recovering the first white list through a second white list including at least one CSG ID of at least one CSG cell to which the UE is registered.
