    Abstract: A method for transmitting or receiving a signal of a Session Management Function (SMF) in a wireless communication system comprises receiving a reject message for a message related to an activation command of a Protocol Data Unit (PDU) session, by the SMF, from a User Equipment (UE); requesting, to an AMF, an Access Management Function (AMF) information on a non-3GPP connection state modification of the UE by the SMF; receiving a message indicating that a non-3GPP connection state of the UE has been changed, by the SMF, from the AMF; and transmitting the message related to the activation command of the PDU session, which includes a new P-CSCF(Proxy-Call Session Control Function) list, by the SMF, to the UE, wherein the message indicating that the non-3GPP connection state of the UE has been changed indicates that a non-3GPP access of the UE has been changed from CM-IDLE to CM-connected.

    Abstract: Provided is a method for handling a packet data unit (PDU) session establishment procedure. The method may performed by an access and mobility management function (AMF) node and comprise: determining whether to reject a PDU session establishment request. The determination may be performed if the PDU session establishment request includes an existing PDU session identifier. Based on the existing PDU session identifier, an identifier of a session management function (SMF) node may be acquired. The PDU session establishment request may be accepted, if it is determined based the identifier of the SMF node that the SMF node and the AMF node belong to a same PLMN. The PDU session establishment request may be further accepted, if it is determined based the identifier of the SMF node that the SMF node belongs to a HPLMN. The PDU session establishment request may be rejected, if it is determined based the identifier of the SMF node that the SMF node and the AMF node do not belong to the same PLMN or the SMF node does not belong to the HPLMN.

    Abstract: A method of operating a first user equipment (UE) in a wireless communication system is disclosed. The method includes releasing a first PC5 radio resource control (RRC) connection for which sidelink (SL) radio link failure (RLF) has been declared among a plurality of PC5 RRC connections by the first UE, informing a PC5 unicast link associated with the first RRC connection by a PC5 unicast link identifier (ID) to a vehicle-to-everything (V2X) layer of the first UE by an access stratum (AS) layer of the first UE, and releasing the PC5 unicast link based on the PC5 unicast link ID by the V2X layer of the first UE. The PC5 unicast link ID indicates the PC5 unicast link for which the SL RLF has been declared and the first RRC connection has been released.

    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.
