    Abstract: Provided in one disclosure of the present specification is a method for operating a session management function (SMF) node for managing a protocol data unit (PDU) session. The method can comprise a step of obtaining analysis information from a network data analytics function (NWDAF) node. The obtained analysis information can comprise information relating to a user equipment (UE) presence pattern analysis in a local are data network (LADN) service area. The method can comprise a step of determining a procedure to be performed for the LADN PDU session on the basis of the information relating to the UE presence pattern analysis.

    Abstract: Provided is a method and device for an N14 interface support indicator for service continuity. A next generation radio access network (NG-RAN) node of a first network receives an initial UE context configuration request message from an access and mobility management function (AMF) of the first network. The initial UE context configuration request message includes (i) a registration acceptance message that is a response to a registration request message, and (ii) information on at least one second network supported by the first network, and the registration acceptance message includes information on whether an N14 interface between the AMF of the first network and an AMF of the at least one second network is supported. The NG-RAN node of the first network initiates handover to one network among the at least one second network, based on the information on the at least one second network.

    Abstract: One disclosure of the present specification provides a method for performing, by a network node, communication associated with an MA PDU session. The method may comprise the steps of: receiving information indicating that PS data off has been activated for an MA PDU session of a UE; updating a PCC rule on the basis of the information indicating that the PS data off has been activated for the MA PDU session; and transmitting the updated PCC rule to an SMF.

    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.

    Abstract: It is disclosed a method for managing a PDU session in a wireless communication system and an apparatus for supporting the same. Particularly, a method for performing handover of a User Equipment (UE) performed by a source Radio Access Network (RAN) that includes a processor, a memory and a communication module in a wireless communication system may include determining to initiate handover to a target RAN; and transmitting a Handover Required message to a source Access and Mobility Management Function (AMF), and the handover is a handover in a case that there is no interface between the RANs or AMF change is required, and the Handover Required message includes a PDU session Identifier (ID) of an activated Protocol Data Unit (PDU) session.

    Abstract: A method for updating local access data network (LADN) information by an access and mobility management function (AMF) in a wireless communication system is disclosed. The method includes, based on an update occurring in the LADN information for a LADN service configured for a user equipment (UE), receiving the updated LADN information, the updated LADN information including information on an updated LADN service area and information on an updated LADN data network name (DNN); and transmitting the updated LADN information to the UE, wherein the AMF is determined based on the updated LADN service area.
