Abstract: A signal transmission and reception method by a session management function (SMF) in a wireless communication system according to an embodiment of the present invention comprises the steps of: the SMF determining whether or not a protocol data unit (PDU) session is to be activated; and the SMF transmitting a message comprising a session management (SM) message to an access and mobility management function (AMF). The PDU session is a PDU session which should be activated by means of a user equipment (UE) which received the SM message. The message comprising the SM message comprises information for activating the PDU session by means of the AMF.

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: 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 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.

Abstract: A disclosure of the present specification provides an operating method for user equipment (UE) supporting a multiple universal subscriber identity module (USIM). The operating method may comprise the steps of: transmitting, by the UE, a first radio resource control (RRC) message to a first radio access network (RAN) in a first network; and receiving, by the UE, a second RRC message from the first RAN. The first RRC message may be transmitted on the basis of determination that the UE moves from the first network to a second network. The first RRC message may include first information about one or more protocol data unit (PDU) sessions established via the first RAN. The first and second RRC messages may be used to change an RRC state to an RRC idle state or an RRC deactivated state.

Abstract: A method for transmitting and receiving a signal related to switching 3rd generation partnership project (3GPP) access to a 5th generation system (5GS) in an evolved packet system (EPS) in a wireless communication system includes: a step in which a second access and mobility management function (AMF) receives a message, related to a registration request and including a first 5G globally unique temporary identifier (5G-GUTI), from a UE that receives non-3GPP access service through the 5GS and 3GPP access service through the EPS; and a step in which the second AMF transmits to the UE, a message related to a registration acceptance and including a second 5G-GUTI. The first 5G-GUTI includes ID information on the first AMF which serves the non-3GPP access of the UE, and the second 5G-GUTI includes ID information on the second AMF which serves both the non-3GPP access and the 3GPP access of the UE.
