Claim Text:
1. A method in a first base station supporting a first cell for restricting frequency access in a wireless communication system having a plurality of base stations, comprising: receiving, from a network node, a list of forbidden frequencies related to a mobile station, wherein the list of forbidden frequencies indicates frequencies that the mobile station is not allowed to use for cell reselection to neighbor cells; and transmitting, to the mobile station, information indicating allowed frequencies to be used by the mobile station in idle state when performing cell reselection, wherein the allowed frequencies are identified by the first base station based on the list of forbidden frequencies, wherein at least one of the allowed frequencies identified based on the list of forbidden frequencies is to be used by the mobile station for performing a cell search on neighbor cells of the first cell and for measuring cell-specific information on the searched neighbor cells, and wherein only the allowed frequencies are to be used by the mobile station for cell reselection evaluation.
