Abstract: A disclosure of the present specification provides a method for processing establishment of a protocol data unit (PDU) session by an access and mobility management function (AMF) node. The method may include a step of receiving a PDU session establishment request message from a user equipment (UE) via either a first access or a second access. The PDU session establishment request message may include information indicative of a multi access (MA) PDU session. The method may include a step of selecting a session management function (SMF) node supporting the MA PDU session on the basis of the information indicative of the MA PDU session. The method may include a step of sending the PDU session establishment request message to the SMF node supporting the MA PDU session.

Abstract: Disclosed herein is a network-initiated deregistration method by an access and mobility management function (AMF) in a wireless communication system, including: receiving a first message having a removal reason configured to subscription withdrawn from a unified data management (UDM); and transmitting a deregistration request message for requesting the deregistration to a user equipment (UE), in which the deregistration is enabled to be performed for all accesses in which the UE is registered when the removal cause received from the UDM through the first message indicates the subscription withdrawn of the UE.

Abstract: A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

Abstract: In an aspect of the present invention, a method for a user equipment (UE) to perform reflective quality of service (QoS) in a wireless communication system may include the steps of receiving a downlink packet from a network, wherein the downlink packet is a packet to which the application of the reflective QoS is indicated; deriving a QoS rule based on the downlink packet; applying a QoS marking of the downlink packet to an uplink packet using the QoS rule and transmitting the uplink packet to the network; and restarting a timer associated with the QoS rule when the downlink packet is received before the timer expires.

Abstract: According to an aspect of the present invention, a method for transporting a non-access stratum (NAS) message of an access and mobility management function (AMF) in a wireless communication system may include: receiving, from a user equipment (UE), an uplink (UL) NAS message including a session management (SM) message for a request related to a protocol data unit (PDU) session; transporting, to a predetermined second Session Management Function (SMF), the SM message if it is determined that it is impossible to route the SM message to a first SMF as a transport target of the SM message; receiving, from the second SMF, an SM rejection message for the SM message; and transmitting, to the UE, a downlink (DL) NAS message including the SM rejection message.

Abstract: A method for a user equipment (UE) connecting to a network includes: if second connection is to be executed by means of a second access, determining whether or not first connection has been previously executed by means of a first access; and, if the first connection by means of the first access has been executed and the second connection by means of the second access is determined to be an addition, transmitting a connection request message comprising identification information of a control plane (CP) function node. The identification information of the control plane (CP) function node could have been obtained during the first connection by means of the first access. Both the first connection by means of the first access and the second connection by means of the second access can be managed by means of the control plane (CP) function node.
