    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: 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 disclosure of the present specification provides a method by which an AMF node of a first network performs communication on the basis of a plurality of SIMs. The method comprises the steps of: receiving a registration request message from a terminal through a base station of the first network; receiving, from an SMF node of the first network, a first message including information requesting the activation of a PDU session of the terminal; receiving a second message that includes caller's ID information related to downlink data; and transmitting, to the terminal, a paging message or a non-access stratum (NAS) notification message including the caller's ID information through the base station of the first network.

    Abstract: One disclosure of the present specification provides a method for operating in relay user equipment (UE). The method may comprise the steps of: receiving a communication request message directly from a first remote UE; performing a procedure for establishing an access and mobility management function (AMF) entity and a protocol data unit (PDU) session; and storing mapping information between an identifier of a PC5 link with the first remote UE and an identifier of the PDU session on the basis of the PDU session being established for an unstructured PDU session type for unstructured traffic.

    Abstract: One disclosure of the present specification provides a method by which an AMF performs communication related to a network slice. The method may comprise the steps of: receiving a PDU session establishment request message including information about a second PDU session; determining to forward a UE to a second RAN node supporting a second network slice; transmitting a message including information indicating that the UE needs to be forwarded to the second RAN node supporting the second network slice; receiving a handover required message; and transmitting a request message for deactivating the first PDU session related to a first network slice.
