Abstract: A registration method of a user equipment (UE) in a wireless communication system is disclosed. The registration method includes transmitting a registration request message to an access and mobility management function (AMF), wherein the registration request message includes requested network slice selection assistance information (NSSAI) including single (S)-NSSAI corresponding to a network slice to which the UE intends to register with; and receiving, from the AMF, a registration accept message as a response to the registration request message, wherein if at least one of the S-NSSAI included in the requested NSSAI is rejected by the AMF, the registration accept message includes the rejected S-NSSAI and a reason for refusal for the rejected S-NSSAI.

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.
