Abstract: The present description discloses a method for performing network selection and traffic routing by a user equipment (UE). The method can comprise the steps of: a non-access stratum (NAS) of the UE receiving from a mobility management entity (MME) an indication, for wireless local area network (WLAN) offloadability for a first public data network (PDN) connection, and information about a network-based IP flow mobility (NBIFOM); the NAS of the UE determining whether or not a collision exists between the indication and information; the NAS of the UE deciding for a suspension of the NBIFOM on the basis of the existence of collision; and the NAS of the UE transmitting to a PDN gateway (P-GW) a message or information, notifying the suspension of the NBIFOM, on the basis of the decision for the suspension of the NBIFOM.

Abstract: A method for updating an area and a device for the same in a wireless communication system is disclosed. Particularly, a method for performing a Tracking Area Update (TAU) with a Mobility Management Entity (MME) change performed by a first MME in a wireless communication system may include receiving a Context Request message from a second MME during the TAU procedure and transmitting a Context Response message to the second MME in response to the Context Request message, wherein an indication that there are downlink data buffered in the S-GW may be included in the Context Response message when downlink data is buffered in a Serving Gateway (S-GW) and a buffering time of the downlink data in the S-GW is not expired.

Abstract: A method for transmitting and receiving data in a wireless communication system, and a device therefor are disclosed. Particularly, a method for transmitting downlink data in a packet data network gateway (P-GW) in a wireless communication system can comprise the steps of: receiving, from an application server, downlink data in which an Internet protocol (IP) header including an IP address of a terminal is encapsulated; removing the IP header from the downlink data; and transmitting, to a serving gateway (S-GW), the downlink data from which the IP header is removed through a bearer identified by the IP address of the terminal, so as to transmit, to the terminal, the downlink data from which the IP header is removed.

Abstract: Disclosed are a serving node relocating method in a wireless communication system and a device for same. In detail, a method for relocating, by a first serving node, a serving node in a wireless communication system can include: receiving a tracking area update (TAU) request message from a terminal; transmitting an update location request to a home subscriber server (HSS), when the first serving node having received the TAU request message is different from a second serving node that is an old node; and transmitting an update location message to a service capability exposure function (SCEF), when the first serving node is different from the second serving node that is the old node and a connection for transmitting/receiving non-internet protocol (non-IP) data via the SCEF is configured in the terminal.

Abstract: Provided is a method for making it impossible to track a vehicle performing vehicle-to-everything (V2X) communication through a network. The network may allocate the same IP address to all UEs performing V2X communication. Since the UEs performing V2X communication transmit data using the same IP address, an application server cannot track a vehicle transmitting corresponding data.

Abstract: A method and apparatus for performing call relay in a wireless communication system is provided. A relaying user equipment (UE) configures a call order or priority among neighboring UEs, selects at least one neighboring UE among the neighboring UEs, and establishes a call or a session between the selected neighboring UE and a caller UE.

Abstract: A method for managing an area of a terminal in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method for performing, by a terminal, location area update in a wireless communication system may comprise the steps of: transmitting, to a network node, a first request message including an additional cell list comprising one or more neighboring cells of a serving cell of the terminal; receiving, from the network node, a first accept message including information indicating acceptance of the use of the additional cell list; and, when a changed serving cell of the terminal belongs to a tracking area configured to the terminal and does not belong to the additional cell list, performing a cell-based area update procedure.
