Abstract: One disclosure of the present specification provides a method by which an AMF performs communication. The method comprises the steps: receiving a first message including information that a handover of a UE is required, from a source base station; transmitting a handover request message including information on a first network slice related to a PDU session used by the UE, to a target base station; receiving a second message including remapping information including information that network slice remapping has been performed from the first network slice to a second network slice for the PDU session, from the target base station; transmitting, on the basis of the remapping information, an update request message for network slice information for the PDU session by using a SMF, wherein the network slice information is updated by means of a PCF and delivered to the UE.

Abstract: A disclosure of the present specification provides a method for performing multicast-related communication by a UE. The method may comprise the steps of: on the basis of first location information on a service area related to a local multicast service, determining that the UE is located within the service area; on the basis of the determination that the UE is located within the service area, transmitting, to an SMF, a first join request message to join the local multicast service: and receiving a join rejection message from the SMF in response to the first join request message.

Abstract: The present specification provides a method for processing, by an access and mobility management function (AMF) device in a first network, a request from a user equipment (UE). The method may comprise receiving, by the AMF device in the first network, a first request message from the UE that supports multiple universal subscriber identity modules (USIMs) and has received a paging message from a second network. The first request message may comprise information on one or more protocol data unit (PDU) sessions and information on release. The method may comprise transmitting a second message to a session management function (SMF) device in the first network. The second message may comprise information on the one or more PDU sessions based on the first request message. The method may comprise performing a procedure for releasing with a radio access network (RAN) in the first network.

Abstract: Provided are a method and a device for supporting generation of a dedicated protocol data unit (PDU) session for particular user traffic. A user equipment (UE) operating in a wireless communication system determines whether to establish a dedicated protocol data unit (PDU) session exclusively used for traffic matched to a particular traffic descriptor (TD), on the basis that a route selection descriptor (RSD) associated with the particular TD includes an indicator indicating whether to establish the dedicated PDU session. The UE requests a network to establish the dedicated PDU session on the basis of the determination of dedicated PDU session establishment.

Abstract: One embodiment of the present specification can provide a method for performing a protocol data unit (PDU) session-related procedure. The method can comprise the steps of: transmitting, to a session management function (SMF) device, a PDU session-related message including a first indication related to communication through a PC5 link; and receiving a response message from the SMF device. The response message can include: a first quality of service (QoS) rule to be used on a Uu link; a second QoS rule to be used on a PC5 link; and a path selection rule about whether data should be transmitted through the Uu link or the PC5 link.
