Abstract: Provided are a method for user interface (UI)/user experience (UX) display for supporting service continuity when a disaster situation ends, and a device supporting same. A user equipment (UE) receives, from a disaster roaming PLMN, a configuration update command message including first information indicating that a disaster condition of a home PLMN (HPLMN) has ended, and displays second information relating to whether to maintain a service that is being received from the disaster roaming PLMN, on the basis of the first information and the fact that the disaster condition of the HPLMN has ended. The UE also waits until the service that is being received from the disaster roaming PLMN ends, and performs, after the service that is being received from the disaster roaming PLMN ends, a procedure of deregistration from the disaster roaming PLMN on the basis of the first information.

Abstract: A network registration method for traffic steering and a device supporting the same is provided. An Access and mobility Management Function (AMF) receives a registration request message from a UE over a second non-3rd Generation Partnership Project (non-3GPP) access. The registration request message includes information related to access witching from a first non-3GPP access to the second non-3GPP access. Based on the registration request message, the AMF i) performs a normal registration procedure, and ii) delays a Unified Data Management (UDM) registration procedure. In addition, upon receiving, from a Session Management Function (SMF), information informing that the access switching from the first non-3GPP access to the second non-3GPP access is completed for the UE, the AMF performs an Access Network (AN) release procedure over the first non-3GPP access, performs the delayed UDM registration procedure.

Abstract: One disclosure of the present specification provides a method by which a network control node performs communication. The method comprises the steps of: determining whether to request, from a network function (NF), control for a network slice on the basis of a session, which is managed by a network control node, being related to an interworking procedure and on the basis of the network slice being controlled by a provider policy set in the network control node, the network slice being related to the session; transmitting a control request message for the network slice to the NF, on the basis of the determination that the network control node requests control for the network slice; and receiving a response message from the NF, wherein the response message includes information about whether the session is available in the network slice.

Abstract: A disclosure of the present specification provides a method of performing communication related to a network slice by a network node. The method may comprise the steps of: receiving a registration request message from a UE; determining, on the basis of information on a network slice, whether the UE is allowed to access the network slice; and when it is determined that the UE is not allowed to access the network slice due to a network slice limit control, transmitting, to the UE, a registration acceptance message including information on a waiting network slice.

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: Provided in one disclosure of the present specification is a user equipment (UE) for establishing a Protocol Data Unit (PDU) session. The UE may include: a transmission and reception unit; and a processor for controlling the transmission and reception unit. The processor may perform: a step for assessing whether there is a possibility of the PDU session being handed over to a non-3rd Generation Partnership Project (non-3GPP) access; a step for determining the ID of the PDU session according to the assessment; and a step for transmitting a message including the determined ID of the PDU session.

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.

Abstract: Systems and techniques for handling a protocol data unit (PDU) session by a wireless device implementing an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system. An example technique includes determining, by the AS layer of the wireless device, whether a user plane for the PDU session is activated or released; transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is activated, first information indicating that the user plane for the PDU session is activated; and transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is released, second information indicating that the user plane for the PDU session is released.

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: One disclosure in the present specification provides a session management method performed by a session management function (SMF) node. The session management method may comprise: a step of transmitting, to a user plane function (UPF) node, a request message for discarding traffic buffering, when a notification of the detection of particular traffic associated with a wireless device has been received, and if additional authentication is required for the particular traffic; and a step of transmitting a message for triggering the wireless device to establish a new packet data unit (PDU) session, to an access and mobility management function (AMF) node.
