PURPOSE: An apparatus which selects a cell through a personal network or a home cell in a mobile communication system and a method thereof are provided to select a cell by confirming whether a terminal is possible to access a specific cell or not. CONSTITUTION: A transceiver (501) receives information about a neighboring cell list from a serving cell and information about a closed subscriber group (CSG) cell. The transceiver receives CSG information and CSG ID from a candidate cell which is determined based on a measurement. A control unit performs a measurement about at least one neighboring cell based on information about the neighboring cell list. The control unit determines a candidate cell based on the measurement. The control unit indicates that the CSG information is connectable to the CSG cell through the terminal. In case the CSG ID is included in a CSG list which is set in the terminal, the control unit selects the candidate cell.
