    Abstract: A method and apparatus for updating an access network discovery and selection functions (ANDSF) policy in a wireless communication system is provided. A user equipment (UE) receives the ANDSF policy and radio access network (RAN) assistance information for the ANDSF policy and a RAN rule, and further receives a configuration indicating whether both the ANDSF policy and the RAN rule are utilized for access network selection and traffic routing. Only if the received configuration indicates that the RAN rule is not utilized for the access network selection and traffic routing, the UE updates the ANDSF policy based on the received RAN assistance information, and performs the access network selection and traffic routing based on the received configuration.

    Abstract: A method by which a terminal performs cell measurement by selectively using reference signals (RSs) is provided. The terminal receives, from a network, a common RS (CRS) measurement configuration and a discovery RS (DRS) measurement configuration with respect to a frequency to be measured. If the network has configured a physical cell ID (PCID) list for CRS-based DRS measurement with respect to the frequency to be measured, DRS measurement is performed on cells included in the PCID list, and CRS measurement is performed on cells not included in the PCID list. If the network has not configured the PCID list for CRS-based DRS measurement with respect to the frequency to be measured, DRS measurement is performed on all cells belonging to the frequency to be measured.

    Abstract: A method and apparatus for performing traffic steering in a wireless communication system is provided. A user equipment (UE) may be configured with a primary cell (PCell) and at least one secondary cell (SCell) by carrier aggregation. Or, the UE may be configured with a PCell of a master evolved NodeB (MeNB) and a primary SCell (PSCell) of a secondary eNB (SeNB) by dual connectivity. For one embodiment, the UE receives radio access network (RAN) assistance information on the PCell, and evaluates conditions for traffic steering only on the PCell based on the received RAN assistance information. For another embodiment, the UE receives RAN assistance information for each of a plurality of serving cells, and performs traffic steering between one serving cell, among the plurality of serving cells, and a wireless local area network (WLAN).

    Abstract: Provided are a device-to-device (D2D) operation method and device which are performed by a terminal in a wireless communication system. The method comprises: receiving D2D configuration information indicating a plurality of resources which can be used for a D2D operation from a network; selecting a specific resource from among the plurality of resources; and performing the D2D operation with another terminal using the selected specific resource, wherein the specific resource is selected on the basis of a reference signal received power (RSRP) which the terminal has received from the network.
