Abstract: A method for discarding at least one packet by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of storing the at least one packet received from an upper layer in a buffer; determining whether or not a number of packets in the buffer is equal to or greater than a threshold value; and discarding the at least one packet from the buffer when the number of packets in the buffer is equal to or greater than the threshold value.

Abstract: One embodiment of the present invention relates to a method for managing a connection of an UE for transmitting and receiving a V2X message of a first network node in a wireless communication system, the connection management method comprising the steps of: allowing a first network node to determine that an UE for performing only a PC5 operation will be maintained in the ECM _CONNECTED state; and allowing the first network node to transmit information requesting the release of a part of a packet data network (PDN) connection, to a second network node, after the determination.

Abstract: A user equipment (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.

Abstract: According to an aspect of the present invention, a method for transporting a non-access stratum (NAS) message of an access and mobility management function (AMF) in a wireless communication system may include: receiving, from a user equipment (UE), an uplink (UL) NAS message including a session management (SM) message for a request related to a protocol data unit (PDU) session; transporting, to a predetermined second Session Management Function (SMF), the SM message if it is determined that it is impossible to route the SM message to a first SMF as a transport target of the SM message; receiving, from the second SMF, an SM rejection message for the SM message; and transmitting, to the UE, a downlink (DL) NAS message including the SM rejection message.

Abstract: One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) to obtain an identifier of a visited public land mobile network (V-PLMN) in order to register a user equipment (UE) roaming in the V-PLMN into an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving a response message from an Interrogating-CSCF (I-CSCF) in response to the transmission of a REGISTER message for registering a user equipment into an IMS network; determining whether the received response message is a 401 unauthorized message; when the received response message is a 401 unauthorized message, transmitting the response message to the user equipment and generating an interface for transmitting and receiving data to and from an entity of an EPC network; and receiving an identifier of the V-PLMN from the entity of the EPC network.

Abstract: One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN) to register a roaming user equipment with an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving an identifier of a visited public land mobile network (V-PLMN) in which a user equipment is roaming, wherein the identifier of the V-PLMN is received in a state where packet data network (PDN) connection for the user equipment is established but the user equipment is not registered with the IMS network; receiving, from the user equipment, a REGISTER message for registration with the IMS network; adding the identifier of the V-PLMN to a header of the REGISTER message; and transmitting the REGISTER message to which the identifier of the V-PLMN is added to an Interrogating-CSCF (I-CSCF).

Abstract: One embodiment of the present invention provides a method by which a network node performs an operation related to a vehicle to everything (V2X) message transmission to a user equipment (UE) in a wireless communication system, the method comprising the steps of: allowing the network node to receive a notify broadcast area message; allowing the network node to receive a V2X message after receiving the notify broadcast area message; and allowing the network node to determine a first eNB which will transmit the V2X message to the UE, on the basis of the notify broadcast area message, without performing session update request procedures.
