1. A method for saving power corresponding to a closed subscriber group, hereafter called CSG, cell selection for a user equipment of a wireless communication system, the method comprising:
- permanently stopping CSG cell search when the user equipment roams to a visited network, wherein the user equipment comprises a whitelist comprising identities of accessible CSG cells and the whitelist further provides at least one identity of accessible network corresponding to the CSG cells, and permanently stopping the CSG cell search comprises;
detecting presence of the visited network; and
stopping searching the CSG cells when the visited network is presented.
