Abstract: A method and apparatus for applying assistance information for traffic steering between a 3rd generation partnership project (3GPP) access network and a non-3GPP access network in a wireless communication system is provided. A user equipment (UE) receives assistance information for traffic steering through a dedicated signaling from an eNodeB (eNB), and starts a timer upon entering an idle mode. The UE applies the assistance information received through the dedicated signaling until the timer expires. After the timer expires, the UE applies assistance information received through a broadcast signaling.

Abstract: A method and apparatus for performing a cell selection or a cell reselection in a wireless communication system is provided. A user equipment (UE) receives information on whether a cell supports a relay functionality or not, and performs a cell selection or a cell reselection according to the information. If the information indicates that the cell does not support the relay functionality, the cell can be considered as barred for relay functionality.
