Abstract: One disclosure in the present specification provides a method for a session management function (SMF) node to manage a session. The method may comprise: a step of generating a packet data unit (PDU) session for a user equipment (UE); a step of receiving information on the UE from an access and mobility management function (AMF) node; and a step of determining, based on the information on the UE, whether or not to transmit an indication for notifying a user plane function (UPF) to discard downlink data of the PDU session for the UE. Here, the determination may be performed by factoring in whether or not the PDU session is about a first service provided to the UE.

Abstract: A network device having an access and mobility management function (AMF) in the present invention transmits, to a base station, a request message for making a request to perform a radio resource control (RRC) state report for a user device. The base station transmits, to the network device, a report message including information for indicating whether the user device is in a RRC_CONNECTED state or a RRC_INACTIVE state.

Abstract: One disclosure of the present specification provides a method in which an access and mobility management function (AMF) node processes a packet data unit (PDU) session establishment procedure. The method may include a step of determining whether to reject a PDU session establishment request or not. Here, the determining step may be performed when the PDU session establishment request includes an identifier of an existing PDU session. On the basis of the identifier of the existing PDU session, an identifier of a session management function (SMF) node may be obtained. If it is determined that the SMF node and the AMF node both belong to the same public land mobile network (PLMN) on the basis of the identifier of the SMF node, the PDU session establishment request can be accepted. If it is determined that the SMF node and the AMF node both belong to a home PLMN (HPLMN) on the basis of the identifier of the SMF node, the PDU session establishment request can be accepted.

Abstract: An embodiment of the present invention relates to a method for performing, by unified data management (UDM), a procedure related to registration of an access and mobility management function (AMF) in a wireless communication system, the method comprising the steps of: receiving a message related to registration of a serving AMF of a UE, which includes access type information and AMF identity (ID) information, from a first AMF by the UDM; and when a second AMF registered as a serving AMF of the UE, which corresponds to the access type information, exists, transmitting a deregistration-related message to the second AMF by the UDM.

Abstract: It is disclosed a method for utilizing LADN in a wireless communication system and an apparatus for the same. Particularly, the method of establishing a protocol data unit (PDU) session for a local area data network (LADN) service by a user equipment (UE) in a wireless communication system may include transmitting to an Access and mobility Management Function (AMF), a registration request including information for informing a request of LADN information for the LADN service; receiving, from the AMF, a registration accept for informing that the registration request is accepted, the registration accept including the LADN information; and establishing a PDU session for the LADN service by performing a PDU session establishment procedure.
