Abstract: One disclosure of the present specification provides a method in which a user equipment (UE) performs an attach request procedure. The method comprises a step of transmitting an attach request message to a second system when an intersystem change from a first system to the second system is required in a state where a back-off timer associated with a data network name (DNN) based congestion control is running. The attach request message may include information on a packet data unit (PDU) session used by the UE in the first system. The information on the PDU session may be used so as not for the attach request message to be rejected by a second network, even if the back-off timer associated with the DNN-based congestion control is running.

Abstract: A user equipment according to the present invention performs a handover from a first system to a second system. When a user equipment receives a command to hand over to the second system, while using a plurality of protocol data unit (PDU) sessions for the same data network (DN) in the first system, the user equipment transmits first session information of a first PDU session among the plurality of PDU sessions, establishes a packet data network (PDN) connection with the second system, on the basis of the first session information, and maps the first PDU session to the PDN connection. When the user equipment is required to establish a dedicated bearer for a PDU session (second PDU session) other than the first PDU session among the plurality of PDU sessions, the user equipment transmits a bearer generation request message requesting to generate a dedicated bearer for the PDN connection.

Abstract: Provided in one disclosure of the present specification is a method by which a session management function (SMF) node manages a session. The method can comprise the steps of: transmitting, to an access and mobility management function (AMF) node, a registration request for notifying of state information of user equipment (UE) capable of accessing a local area data network (LADN) through any one of a first access network and a second access network; receiving, from the AMF node, changed state information when the state information of the UE is changed; and determining whether to release or deactivate a PDU session of the UE on the basis of the received information.

Abstract: Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method comprises the steps of: allowing a non-access-stratum (NAS) layer of the UE to transfer information on an important service and a NAS signaling request to a radio resource control (RRC) layer, when the important service is required even if access to a cell is currently interrupted or a back-off timer is operated; and allowing the RRC layer to skip or override an inspection for access control on the basis of the information on the important service, wherein, the information on the important service can be set in advance.

Abstract: A method for selecting a serving AMF of a network node in a wireless communication system includes receiving a registration request message of a user equipment (UE), the registration request message including a network slice selection assistance information (NSSAI) for a slice requested by the UE and priority information of the NSSAI; determining whether the NSSAI is valid for the UE; when the NSSAI is valid for the UE, searching a first AMF which is able to support the NSSAI based on the priority information; and when the first AMF is searched, selecting the first AMF as the serving AMF serving the UE and transmitting the registration request message to the first AMF.

Abstract: Provided is a method for a wireless device for transmitting an RRC message according to one disclosure of the present specification. The method may comprise a step for an NAS stratum of the wireless device transmitting an NAS signaling request message to an AS layer to transmit the former to a network node. The NAS signaling request message can comprise therein an indication of one or both preferred or required plans from among the plans for optimizing the EPS for CIoT using a control plane (CP) or a user plane (UP). The method may comprise a step for the NAS stratum of the wireless device receiving, from the AS stratum, an NAS signaling acceptance message or NAS signaling rejection message from the network node.

Abstract: Disclosed herein are a method for tracking area update in a wireless communication system and an apparatus therefor. Specifically, a method for user equipment (UE) to perform a tracking area update (TAU) procedure in a wireless communication system comprises: a step of transmitting a TAU request message to a mobility management entity (MME); and a step of receiving a TAU accept message from the MME, wherein if the UE uses signaling optimization to enable the delivery of user data through a control plane over the MME, and the UE does not have pending user data to be transmitted through a user plane and has pending user data to be transmitted through the control plane over the MME, then a first active flag can be set in the TAU request message.
