Abstract: In the present specification, provided is an operation method for an access and mobility management function (AMF). The method comprises a step of receiving a session management (SM) context state notification message from a session management function (SMF). The SM context state notification message can be received on the basis of the failure of a protocol data unit (PDU) session establishment procedure. The PDU session establishment procedure can be triggered for a handover of a PDU session between non-3rd generation partnership project (non-3GPP) access and 3GPP access. The method includes a step of updating an access type related to the PDU session on the basis of the SM context state notification message.

Abstract: Provided in one embodiment of the present specification is a method for user equipment (UE) for an Internet protocol multimedia subsystem (IMS) voice session. The method can comprise the steps of: establishing an EMS voice session by using a non 3GPP interworking function (N3IWF) or an enhanced packet data gateway (ePDG) through non-3rd generation partnership project (3GPP) access; determining that voice is not supported on a current NG-RAN on the basis of that the UE must moves the IMS voice session to a 3GPP access; and handing over a protocol data unit (PDU) session for the IMS voice session of the non-3GPP access to an evolved packet core (EPC) of the 3GPP access on the basis of the determination.

Abstract: A disclosure of the present specification provides a method for a terminal to perform communication related to an IMS. The method may comprise the steps of: receiving, by an NAS layer of a terminal, a first request message from an IMS layer of the terminal, wherein the first request message includes information related to IMS signaling for a non-service attempt and information about a first access category among a plurality of access categories related to an IMS service, and the IMS signaling for the non-service attempt is signaling which does not request the IMS service; and transmitting, by the NAS layer of the terminal, a second request message including the information about the first access category to an RRC layer of the terminal.

Abstract: Disclosed in the present specification is a method by which a terminal acquires service function chain (SFC) information. The method comprises the steps of: transferring, to a controller, the terminal state information and/or the terminal configuration information; and receiving the SFC information, determined by the controller, by considering the terminal state information and/or the terminal configuration information, wherein the SFC information includes logical path information of a virtualized network function (VNF). The method can also include a step for receiving sub-chain information, determined by the controller, on the basis of the SFC information, or determining the sub-chain information on the basis of the SFC information.

Abstract: According to one aspect of the present invention, a method for supporting a user equipment (UE) handover of a target (T)-access and mobility management function (AMF) in a wireless communication system may comprise the steps of: receiving a UE context creation request message from a source (S)-AMF, wherein the UE context creation request message includes packet data unit (PDU) session identifiers (ID) as a handover target and single (S)-network slice selection assistance information (NSSAI) corresponding to each PDU session ID; determining whether the corresponding S-NSSAI is valid in the T-AMF; and sending, to a session management function (SMF), a PDU session update session management (SM) context request message only for a PDU session ID that corresponds to the S-NSSAI determined to be valid according to the determination result, out of the PDU session IDs.

Abstract: One disclosure of the present specification provides a method by which a session management function (SMF) supports quality of service (QoS). The method can comprise the steps of: determining, on the basis of a QoS flow not being a guaranteed bit rate (GBR) QoS flow in a multi-access (MA) protocol data unit (PDU) session, that a QoS profile is transmitted to both a third generation partnership project (3GPP) access and a non-3GPP access; determining, on the basis of the QoS flow being the GBR QoS flow in the MA PDU session, that the QoS profile is transmitted to only one of the 3GPP access and the non-3GPP access; and transmitting the QoS profile on the basis of the determinations.
