Claim:
1. A method of performing cell selection performed by a terminal in a wireless communication system, the method comprising: obtaining a public land mobile network (PLMN) list from a serving cell, wherein the PLMN list enumerates a plurality of PLMNs based on operators sharing the serving cell, and wherein the plurality of PLMNs include a primary PLMN and at least one secondary PLMN, and wherein the primary PLMN is the first enumerated in the PLMN list; obtaining cell reselection information from the serving cell, wherein the cell reselection information includes a plurality of enumerated cell reselection information sets associated with the plurality of PLMNs, wherein the cell reselection information is obtained separately from the PLMN list, wherein the enumeration of the plurality of cell reselection information sets in the cell reselection information corresponds to the enumeration of the plurality of PLMNs in the PLMN list, wherein the plurality of cell reselection information sets include one cell reselection information set associated with the primary PLMN and at least one cell selection information set associated with the at least one secondary PLMN, and wherein each cell reselection information set includes parameters for performing cell reselection by the terminal based on at least one associated PLMN; determining a cell reselection information set associated with a registered PLMN (rPLMN) of the terminal among the plurality of PLMNs, wherein the rPLMN of the terminal is a PLMN that the terminal has registered a position of the terminal, and wherein the determining is performed on the basis of an order according to which the plurality of PLMNs in the PLMN list are enumerated and according to which the plurality of cell reselection information sets in the cell reselection information are enumerated; selecting a target cell by applying the cell reselection information set associated with the rPLMN; and performing cell reselection on the basis of the target cell.
