Abstract: A disclosure of the present specification provides a method for an AMF node to communicate. The method comprises the steps of: receiving, from a UDM node, updated subscriber information about a Remote UE; determining whether to stop a service to the Remote UE on the basis of the updated subscriber information about the Remote UE; and transmitting, to a Relay UE communicating with the Remote UE, a deregistration request message requesting deregistration of the Remote UE.

Abstract: Provided in one disclosure of the present specification is an operation method of a relay user equipment (UE) for a remote UE. The method may comprise a step in which the relay UE receives, from a base station, a radio resource control (RRC) reconfiguration message or an RRC connection reconfiguration message. The RRC reconfiguration message or the RRC connection reconfiguration message may include identification information of a data radio bearer (DRB) shared with the remote UE and information on a protocol data unit (PDU) session which must be deleted or released in the DRB. The method may comprise a step in which an access stratum (AS) layer of the relay UE relays, to a non-access stratum (NAS) layer, information that a user plane (UP) connection of the PDU session was released, on the basis of the received RRC reconfiguration message or the RRC connection reconfiguration message.

Abstract: One disclosure of the present specification provides a method for an SMF node to perform authentication. The method may include the steps of: receiving, from a relay UE, a Remote UE report message related to a Remote UE connected to the relay UE; transmitting a request message to a UDM node or an AMF node on the basis of the Remote UE report message including an SUCI of the remote unit; receiving a response message, including an SUPI of the Remote UE, from the UDM node or the AMF node; and transmitting an authentication request message, requesting authentication for the Remote UE, to an authentication server.

Abstract: One embodiment provides a method by which a network data analytics function (NWDAF) transmits and receives a signal in a wireless communication system, comprising the steps in which an NWDAF receives, from operations and maintenance (OAM), a notification based on a change in a user plane congestion status and transmits, to a V2X application server, analytics for the user plane congestion notification on the basis of the notification through a network exposure function (NEF), wherein the change in the user plane congestion status is determined on the basis of one or more pieces of information including whether a QNC notification is transmitted, and whether the QNC notification is transmitted is determined on the basis of a counter value that increases when an NG-RAN transmits, to an SMF, “GFBR cannot be fulfilled/guaranteed,” and decreases when the NG-RAN transmits, to the SMF, “GFBR cannot be fulfilled/guaranteed.”
