Abstract: Provided are a method for transmitting a device-to device (D2D) discovery message performed by a terminal in a wireless communication system, and a terminal using said method. The method determines individual range classes for a plurality of D2D discovery resource pools; selects a D2D discovery resource pool having a higher ranger class when it is not possible to find a D2D resource pool having the same range class as the range class of the D2D discovery message from the plurality of D2D discovery resource pools; and transmits the D2D discovery message using the selected D2D discovery resource pool.

Abstract: The present invention discloses a proximity based notification method in a wireless communication system and a device for the same. In detail, a proximity based notification method in a wireless communication system supporting device to device communication (D2D) may include the steps of: configuring, by a first terminal, a list of terminals which participate in an notification service and a notification time; broadcasting, by the first terminal, a discovery signal including a first D2D ID on a physical sidelink discovery channel (PSDCH) when the notification time arrives; and outputting, by the first terminal, a notification for notifying that a second terminal is proximate when the first terminal receives a second discovery signal including a second D2D ID from the second terminal included in the terminal list on the PSDCH.

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: One embodiment of the present invention relates to a method by which a terminal performs device-to-device (D2D) communication in a wireless communication system, the method comprising the steps of: converting into a radio resource control (RRC) connection state through the transmission of a service request; being allocated a resource for the D2D communication; transmitting a D2D signal through the allocated resource; and receiving a system information block (SIB) after transmitting the D2D signal, wherein if the SIB includes information on a resource pool, the terminal does not perform an RRC recovery-related operation even if RRC connection failure occurs.

Abstract: There is provided a method of performing measurement. The method may be performed by a user equipment (UE) and comprise: receiving, by the UE, a cell list from a serving cell; if at least one cell in the cell list is detected, performing, by the UE, measurements on a frequency corresponding to the cell list and applying layer 3 filtering for the measurements; and if any cell in the cell list is not detected, not performing the measurements on the frequency corresponding to the cell list.

Abstract: Provided are a method for transmitting a discovery message by a terminal in a wireless communication system, and a terminal using the same. The method comprises: receiving a discovery response (discovery_response) message including a proximity service application code (ProSe application code: PAC); passing a discovery message generated on the basis of the PAC from an upper layer to a lower layer of the terminal; and transmitting the discovery message at the lower layer, wherein the upper layer of the terminal continuously and repetitively passes the discovery message with respect to the PAC to the lower layer until a timer for the PAC expires.
