Abstract: A disclosure of the present invention provides a method in which user equipment (UE) selects a network and performs traffic routing. The method may comprise the steps of: receiving first RAN (radio access network) supporting information; receiving second RAN supporting information; and applying the first RAN supporting information or the second RAN supporting information for selecting a network and routing traffic. Here, when the first RAN supporting information has been received by a Home PLMN, if the UE is registered in a visited PLMN, and if the second RAN supporting information is received by the visited PLMN, the second RAN supporting information may be used.
