Abstract: A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.

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: A disclosure according to the present specification provides a method of having an access by a terminal subscribing to a first public land mobile network (PLMN). The method may comprise a step of transmitting a first request message to a network node via a base station. The base station may be a base station of a second PLMN that broadcasts system information including information about the first PLMN. The method may comprise a step of receiving, from the network node, a first response message that is a response to the first request message. The first response message may include information indicating that there is a service failure in the first PLMN. The method may comprise a step of transmitting a second request message to the second PLMN or reselecting another PLMN instead of the first PLMN, which has a service failure, on the basis of the first response message including the information.

Abstract: A disclosure of the present specification provides a method for managing a PDU session performed by an SMF node. The method may comprise the steps of: determining to release an MA PDU session for at least one access of a 3GPP access and a non-3GPP access; and transmitting a message associated with the release of the PDU session to an AMF node.

Abstract: In the present specification, provided is an operation method for an access and mobility management function (AMF). The method comprises a step of receiving a session management (SM) context state notification message from a session management function (SMF). The SM context state notification message can be received on the basis of the failure of a protocol data unit (PDU) session establishment procedure. The PDU session establishment procedure can be triggered for a handover of a PDU session between non-3rd generation partnership project (non-3GPP) access and 3GPP access. The method includes a step of updating an access type related to the PDU session on the basis of the SM context state notification message.

Abstract: Provided in one disclosure in the present specification is a multi-access (MA) protocol data unit (PDU) session method using user equipment (UE). The method can comprise a step of transmitting a first request message for a performance measurement function (PMF) binding request to a PMF layer of a user plane function (UPF) node on the basis of PMF address information about the UPF node included in measurement assistance information (MAI). The PMF binding request can be performed according to quality of service (QoS) flow. The method can comprise a step of receiving a PMF binding response message from the PMF layer of the UPF node. The PMF binding response message can include a reflective QoS indication (RQI).

Abstract: One disclosure of the present specification provides a method for using a multi-access (MA) protocol data unit (PDU) session of a terminal. The method may comprise the steps of: displaying a configuration screen on whether to use a MA PDU session; displaying information representing the establishment or use of the MA PDU session if the MA PDU session is configured to be usable and if two access networks are both in a usable state; and displaying detailed information on the MA PDU session.

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.”

Abstract: A disclosure of the present specification provides a method for accessing another Public Land Mobile Network (PLMN) instead of a subscribed third PLMN. According to the method, a terminal may access a second PLMN, which provides a service, instead of a first PLMN that is roaming-agreed with the third PLMN. In addition, according to the method, the terminal may display, on a screen, information indicating that access is made to the second PLMN. The second PLMN may provide only a limited service.
