    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: 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 of operating a first user equipment (UE) in a wireless communication system is disclosed. The method includes releasing a first PC5 radio resource control (RRC) connection for which sidelink (SL) radio link failure (RLF) has been declared among a plurality of PC5 RRC connections by the first UE, informing a PC5 unicast link associated with the first RRC connection by a PC5 unicast link identifier (ID) to a vehicle-to-everything (V2X) layer of the first UE by an access stratum (AS) layer of the first UE, and releasing the PC5 unicast link based on the PC5 unicast link ID by the V2X layer of the first UE. The PC5 unicast link ID indicates the PC5 unicast link for which the SL RLF has been declared and the first RRC connection has been released.
