1. A cell selection method of a terminal, the method comprising:
identifying whether a first cell having greatest channel quality is a closed subscriber group (CSG) cell;
identifying, if the first cell is the CSG cell, whether an identification of the first cell is included in a cell list of the terminal;
selecting, if the identification of the first cell is not included in the cell list, a second cell having greatest channel quality after the first cell;
accessing the second cell; and
transmitting a radio resource control (RRC) message including an indicator indicating that a channel quality of the first cell is greater than a channel quality of the second cell, to the second cell,
wherein the second cell is selected based on the channel quality of the second cell and an offset value obtained from first system information, and
wherein the offset value is changed by the terminal if second system information is not received.
