Abstract: A method for managing registration in a wireless communication system and a device for the same are disclosed. More specifically, the method for managing registration performed by a User Equipment (UE), that cannot be paged by a network and does not perform a periodic registration area update, in the wireless communication system, may include receiving a timer value for managing a Deregistered state of the UE from the network during a registration procedure, starting a timer if the UE enters an Idle state, and allowing the UE to enter the Deregistered state if the timer expires.

Abstract: A source BS may determine that handover of a UE to a target BS is needed and transmit a handover request message indicating a request of handover to the target BS to a network node to which the source BS is connected. The handover request message may include radio access network (RAN) type information indicating a target RAN and radio access technology (RAT) type information indicating a target RAT.

Abstract: Provided are a method for user interface (UI)/user experience (UX) display for supporting service continuity when a disaster situation ends, and a device supporting same. A user equipment (UE) receives, from a disaster roaming PLMN, a configuration update command message including first information indicating that a disaster condition of a home PLMN (HPLMN) has ended, and displays second information relating to whether to maintain a service that is being received from the disaster roaming PLMN, on the basis of the first information and the fact that the disaster condition of the HPLMN has ended. The UE also waits until the service that is being received from the disaster roaming PLMN ends, and performs, after the service that is being received from the disaster roaming PLMN ends, a procedure of deregistration from the disaster roaming PLMN on the basis of the first information.

Abstract: A disclosure of the present specification provides a method for performing, by a UE, communication associated with access control. The method may comprise the steps of: acquiring information associated with exception data; determining an access category of an access attempt for the exception data, on the basis of the information associated with the exception data; performing an access control check on the basis of the determined access category; and, when access is allowed according to the access control check, transmitting the exception data.

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.

Abstract: Systems and techniques for handling a protocol data unit (PDU) session by a wireless device implementing an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system. An example technique includes determining, by the AS layer of the wireless device, whether a user plane for the PDU session is activated or released; transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is activated, first information indicating that the user plane for the PDU session is activated; and transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is released, second information indicating that the user plane for the PDU session is released.

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.
