    Abstract: A method of operating a first user equipment (UE) in a wireless communication system is disclosed. The method includes performing an access stratum (AS) configuration procedure with a second UE by the first UE, and transmitting a radio resource control (RRC) message to a base station (BS) based on failure of the AS configuration procedure by the first UE. The RRC message includes information about a destination identifier (ID) of a unicast link related to the failure of the AS configuration procedure.

    Abstract: A method for updating local access data network (LADN) information by an access and mobility management function (AMF) in a wireless communication system is disclosed. The method includes, based on an update occurring in the LADN information for a LADN service configured for a user equipment (UE), receiving the updated LADN information, the updated LADN information including information on an updated LADN service area and information on an updated LADN data network name (DNN); and transmitting the updated LADN information to the UE, wherein the AMF is determined based on the updated LADN service area.

    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wireless communication system, including: receiving a first message having a removal reason configured to subscription withdrawn from a unified data management (UDM); and transmitting a deregistration request message for requesting the deregistration to a user equipment (UE), in which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.
