Abstract: Disclosed are an overload control method in a wireless communication system and a device for the same. Specifically, a method by which a base station performs an overload control in a wireless communication system can include: a step of receiving an overload start message from a core network; a step of receiving a first radio resource control (RRC) message including a non-access stratum (NAS) message from user equipment (UE); and a step of transmitting an RRC connection release message, for instructing the release of an RRC connection, to the UE when an instruction for instructing data transmission through a control plane in the first RRC message is included.

Abstract: A method for a user equipment (UE) to perform public land mobile network (PLMN) selection in a wireless communication system, and which includes selecting, by the UE, a first PLMN; in response to the first PLMN not providing direct communication resources, selecting, by the UE, a second PLMN providing direct communication resources; performing, by the UE, a registration on the second PLMN; receiving, by the UE, a failed registration code of “PLMN not allowed” due to a failing of the registration on the second PLMN; and performing, by the UE, the direct communication on the second PLMN in a limited service state. Further, the UE remains on the first PLMN based on a normal service state and the UE does not perform an additional PLMN selection during a duration of the direct communication in the second PLMN based on the limited service state.

Abstract: A method of performing a radio resource control (RRC) connection procedure of a relay user equipment (UE) in a wireless communication system is disclosed. The method includes, if a RRC connection procedure of a remote UE associated with the relay UE is triggered, receiving, from the remote UE, a first RRC establishment cause for a RRC connection of the remote UE; and if a RRC connection request of the relay UE is not allowed, transmitting, to a base station, a first RRC connection request including the first RRC establishment cause of the remote UE.

Abstract: Disclosed are a method for transmitting and receiving data through a relay in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting and receiving, by a remote user equipment (UE), data to and from a network through a relay UE in a wireless communication system includes: recognizing that small data to be transmitted to the network is generated; performing a discovery procedure through the relay UE and a PC5 interface; and transmitting a PC5 message including the small data to the relay UE when it is verified that the relay UE has an ability to transmit the small data to the network in the discovery procedure, in which when it is indicated that the relay UE supports a small data transmitting procedure by a PC5 discovery message received from the relay UE in the discovery procedure, it may be determined that the relay UE has the ability to transmit the small data to the network.

Abstract: A method and apparatus for triggering a transmission carrier reselection procedure due to high congestion level in a wireless communication system is provided. A wireless device, which selects a carrier and performs data transmission on the carrier, determines that a congestion level of the carrier is not below a threshold for carrier reselection, and triggers the carrier reselection.

Abstract: Disclosed are a method for supporting extended idle mode discontinuous reception activation in a wireless communication system, and an apparatus therefor. Specifically, the method for supporting extended idle mode discontinuous reception (eDRX) activation in a wireless communication system comprises the steps of: when a triggering condition for a tracking area update (TAU) procedure is satisfied, transmitting, by a terminal, a TAU request message to a mobility management entity (MME); and receiving, by the terminal, a TAU accept message from the MME in response to the TAU request message, wherein, while the terminal has a packet data network (PDN) connection for providing an emergency bearer service, an eDRX parameter is negotiated between the terminal and the MME, using the TAU request message and the TAU accept message, but the eDRX may not be used by the terminal.

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 firstPDU 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: 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.
