    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: 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: One disclosure of the present specification provides a method for a multi access (MA) protocol (PDU) session by a device. The method may comprise a step of receiving measurement assistance information from a Session Management Function (SMF) node. The measurement assistance information may be related to the MA PDU session on 3rd generation partnership project (3GPP) access and non-3GPP access. The method may comprise a step of transmitting a report on the basis of the measurement assistance information. The report may include information on availability or non-availability of any one of the 3GPP access or the non-3GPP access. The report may be transmitted to a User Plane Function (UPF) node by means of a user plane.

    Abstract: In order to achieve the above-described object, a disclosure of this specification provides a method for performing, by a UE, a PDU session establishment request, in case information on a LADN area is changed. The method may include the steps of performing a first PDU session establishment request for a first LADN area, in case the first PDU session establishment request is transmitted from outside of the first LADN area, receiving a Reject message rejecting the first PDU session establishment request from a network system, in case the Reject message is received, transmitting a registration update request for updating a LADN area to the network system, receiving information on an updated second LADN area (LADN Service Area 2) as a response to the registration update request, and performing a second PDU session establishment request for the second LADN area.

    Abstract: One disclosure of the present specification provides a method by which a user equipment (UE) performs a protocol data unit (PDU) session establishment procedure for a local area data network (LADN). The method comprises: when a pre-set condition related to an LADN policy is satisfied, transmitting a message requesting an access and mobility management function (AMF) for the LADN policy; receiving, from the AMF, the LADN policy provided by a policy control function (PCF), wherein the LADN policy comprises information about at least one application and information about a LADN data network name (DNN) related to the at least one application; determining a LADN DNN to be used by the UE, on the basis of the LADN policy; and transmitting a PDU session establishment request message related to the determined LADN DNN to the AMF.
