Abstract: A method for transmitting and receiving a signal related to switching 3rd generation partnership project (3GPP) access to a 5th generation system (5GS) in an evolved packet system (EPS) in a wireless communication system includes: a step in which a second access and mobility management function (AMF) receives a message, related to a registration request and including a first 5G globally unique temporary identifier (5G-GUTI), from a UE that receives non-3GPP access service through the 5GS and 3GPP access service through the EPS; and a step in which the second AMF transmits to the UE, a message related to a registration acceptance and including a second 5G-GUTI. The first 5G-GUTI includes ID information on the first AMF which serves the non-3GPP access of the UE, and the second 5G-GUTI includes ID information on the second AMF which serves both the non-3GPP access and the 3GPP access of the UE.

Abstract: One disclosure of the present specification provides a method by which a wireless device transmits an RRC message. The method can comprise the steps of: allowing, an AS layer of the wireless device, to acquire an NAS signaling request message, an RRC establishment cause field, and a call type field from an NAS layer; checking the acquired RRC establishment cause field and the call type field; determining, when the NAS signaling request message includes user data according to an optimization plan through a control plane, whether to perform or skip an examination for access blocking (AB) based on the RRC establishment cause field and/or the call type field; and transmitting, when blocking is not achieved or when the examination is skipped according to the examination result, an RRC connection request message to a base station so as to transmit the NAS signaling request message including the user data.

Abstract: A method of controlling a washing machine. The washing machine includes a tub with an entry hole configured to receive laundry, a drum rotatably disposed in the tub, a ring-shaped gasket disposed along a circumference of the entry hole of the tub, a pump configured to circulate water that is discharged from the tub, and at least one circulation nozzle provided in the gasket and configured to spray the water that is circulated by the pump into the drum. The method includes: supplying water into the tub; rotating the drum; accelerating a pump speed of the pump while the drum rotates; and based on the pump speed of the pump reaching a threshold speed during the acceleration of the pump, opening a spray valve of the washing machine such that water supplied from an external water source is sprayed into the drum through a direct water nozzle.

Abstract: Provided are a method by which a terminal performs an access barring check in a wireless communication system and a device for supporting the same. The method may include: a step for entering an RRC_INACTIVE state; a step for performing the access barring check on a cell; a step for checking that access to the cell is prevented as many times as the maximum number of access attempts; and a step for transitioning from the RRC_INACTIVE state to an RRC_IDLE state.

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 and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

Abstract: A method and apparatus for performing application specific congestion control for data communication (ACDC) in a wireless communication system is provided. A radio resource control (RRC) layer of a user equipment (UE) receives ACDC barring information for a plurality of ACDC categories via system information from a network, determines whether the ACDC barring information for the plurality of ACDC categories contains ACDC barring information for a specific ACDC category selected by upper layers, and if it is determined that the ACDC barring information for the plurality of ACDC categories does not contain ACDC barring information for a specific ACDC category selected by upper layers, performs ACDC barring check by using ACDC barring information for last ACDC category among the plurality of ACDC categories.
