Abstract: One disclosure of the present specification provides a method by which a terminal that joined a first public land mobile network (PLMN) performs a connection. The method may comprise a step for transmitting a first request message to a network node through 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 for receiving, from the network node, a first acceptance message for the first request message. The first acceptance message may include information indicating that there is a service failure in the first PLMN. The method may comprise a step for displaying, on a screen of the terminal, information indicating that the terminal is connected to the second PLMN on the basis of the information.

Abstract: Provided in one embodiment of the present specification is a method for user equipment (UE) for an Internet protocol multimedia subsystem (IMS) voice session. The method can comprise the steps of: establishing an EMS voice session by using a non 3GPP interworking function (N3IWF) or an enhanced packet data gateway (ePDG) through non-3rd generation partnership project (3GPP) access; determining that voice is not supported on a current NG-RAN on the basis of that the UE must moves the IMS voice session to a 3GPP access; and handing over a protocol data unit (PDU) session for the IMS voice session of the non-3GPP access to an evolved packet core (EPC) of the 3GPP access on the basis of the determination.

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 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: 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 are a method for adjusting timer T when disaster roaming occurs, and a device supporting same. When a disaster condition is applied to a home public land mobile network (HPLMN), a user equipment (UE) performs registration with a disaster roaming PLMN. When the registration with the disaster roaming PLMN is performed, a timer for periodically searching for the HPLMN does not operate, and the HPLMN is not searched while the timer does not operate. In addition, the UE re-operates the timer on the basis of the disaster condition no longer being applied to the HPLMN or the UE leaving a disaster area.

Abstract: Provided are a method 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 information indicating that a disaster condition of a home PLMN (HPLMN) has ended. The UE waits until a 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 information indicating that the disaster condition of the HPLMN has ended.

Abstract: According to one aspect of the present invention, a method for supporting a user equipment (UE) handover of a target (T)-access and mobility management function (AMF) in a wireless communication system may comprise the steps of: receiving a UE context creation request message from a source (S)-AMF, wherein the UE context creation request message includes packet data unit (PDU) session identifiers (ID) as a handover target and single (S)-network slice selection assistance information (NSSAI) corresponding to each PDU session ID; determining whether the corresponding S-NSSAI is valid in the T-AMF; and sending, to a session management function (SMF), a PDU session update session management (SM) context request message only for a PDU session ID that corresponds to the S-NSSAI determined to be valid according to the determination result, out of the PDU session IDs.
