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 (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.

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 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.
