Abstract: A registration method of a user equipment (UE) in a wireless communication system is disclosed. The registration method includes transmitting a registration request message to an access and mobility management function (AMF), wherein the registration request message includes requested network slice selection assistance information (NSSAI) including single (S)-NSSAI corresponding to a network slice to which the UE intends to register with; and receiving, from the AMF, a registration accept message as a response to the registration request message, wherein if at least one of the S-NSSAI included in the requested NSSAI is rejected by the AMF, the registration accept message includes the rejected S-NSSAI and a reason for refusal for the rejected S-NSSAI.

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: One disclosure of the present specification provides a method for a multi access (MA) protocol (PDU) session by a device. The method may comprise a step of receiving measurement assistance information from a Session Management Function (SMF) node. The measurement assistance information may be related to the MA PDU session on 3rd generation partnership project (3GPP) access and non-3GPP access. The method may comprise a step of transmitting a report on the basis of the measurement assistance information. The report may include information on availability or non-availability of any one of the 3GPP access or the non-3GPP access. The report may be transmitted to a User Plane Function (UPF) node by means of a user plane.

Abstract: One disclosure of the present specification provides a method by which a user equipment (UE) performs a protocol data unit (PDU) session establishment procedure for a local area data network (LADN). The method comprises: when a pre-set condition related to an LADN policy is satisfied, transmitting a message requesting an access and mobility management function (AMF) for the LADN policy; receiving, from the AMF, the LADN policy provided by a policy control function (PCF), wherein the LADN policy comprises information about at least one application and information about a LADN data network name (DNN) related to the at least one application; determining a LADN DNN to be used by the UE, on the basis of the LADN policy; and transmitting a PDU session establishment request message related to the determined LADN DNN to the AMF.

Abstract: One disclosure of the present specification provides a method for transmitting, by user equipment, a PDU session establishment request. The method comprises the steps of: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message, wherein the PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

Abstract: A disclosure of the present specification provides a method for managing uplink quality of service (QoS) by a base station. The method may comprise the steps of: determining whether a timer, driven by a terminal in relation to reflective QoS, has expired; during driving of the timer of the terminal, transmitting multiple packets within a traffic flow, to which the reflective QoS is applied, without setting at least one of a reflective QoS indication (RQI) and a QoS flow ID (QFI) for the multiple packets therewithin; and before expiration of the timer being driven by the terminal, setting at least one of the RQI and the QFI for at least one packet within the traffic flow and transmitting the set packet.

Abstract: A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.
