Abstract: In order to achieve the above-described object, a disclosure of this specification provides a method for performing, by a UE, a PDU session establishment request, in case information on a LADN area is changed. The method may include the steps of performing a first PDU session establishment request for a first LADN area, in case the first PDU session establishment request is transmitted from outside of the first LADN area, receiving a Reject message rejecting the first PDU session establishment request from a network system, in case the Reject message is received, transmitting a registration update request for updating a LADN area to the network system, receiving information on an updated second LADN area (LADN Service Area 2) as a response to the registration update request, and performing a second PDU session establishment request for the second LADN area.

Abstract: One disclosure of the present specification provides a method for transmitting, by user equipment, a PDU session establishment request. The method comprises the steps of: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message, wherein the PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

Abstract: Provided in one disclosure of the present specification is a method for a wireless device attempting network access. The method may comprise the steps of: an RRC layer of the wireless device receiving, from a cell, a first piece of information relating to an NB-IoT RAT; the RRC layer receiving, from the cell, a second piece of information indicating whether to block access to exception data; the RRC layer obtaining, from an upper layer, an RRC establishment cause set as outgoing exception data, when an NAS signaling process is initiated to transmit the exception data; and performing an access block inspection.

Abstract: Disclosed are a method for updating a UE configuration in a wireless communication system and an apparatus for the same. Specifically, a method for updating a configuration of a user equipment (UE) by an access and mobility management function (AMF) in a wireless communication system may comprise the steps of: determining whether it is necessary to change a configuration of the UE without a request from the UE; and when it is necessary to change the configuration of the UE, transmitting a UE configuration update command message to the UE, wherein the UE configuration update command message comprises updated UE parameters.

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.

Abstract: A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.
