Abstract: One disclosure of the present specification provides a method for operating in relay user equipment (UE). The method may comprise the steps of: receiving a communication request message directly from a first remote UE; performing a procedure for establishing an access and mobility management function (AMF) entity and a protocol data unit (PDU) session; and storing mapping information between an identifier of a PCS link with the first remote UE and an identifier of the PDU session on the basis of the PDU session being established for an unstructured PDU session type for unstructured traffic.

Abstract: One disclosure of the present specification provides a method for supporting redundant protocol data unit (PDU) sessions. The method may be performed by a unified data management (UDM) node and comprise: receiving, from a first session management function (SMF) node, a first message including a first redundancy sequence number (RSN) which is allocated by the first SMF node for managing a first PDU session and an identifier of the first PDU session; transmitting, to a second SMF node for managing a second PDU session, a second message including the first RSN and a PDU session pair ID, which is identical to the identifier of the first PDU session; and receiving, from the second SMF node, a third message including a second RSN which is allocated by the second SMF node and an identifier of the second PDU session. The second PDU session may be duplication of the first PDU session.

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: An embodiment of the present disclosure provides a method for transmitting or receiving a signal relating to a PDU session of a UE in a wireless communication system, the method includes the steps of: transmitting, by a UE in a RRC inactive state, a RRC message for resuming to a base station; and receiving, by the UE, information indicating release of a resource from the base station in response to the RRC message for resuming, wherein the release of the resource is caused by the deactivation of a PDU session of the UE.

Abstract: A method of transmitting and receiving a signal related to quality of service (QoS) prediction by a server in a wireless communication system includes transmitting a request related to QoS prediction subscription to a network data analytics function (NWDAF) by the server, and receiving a notification related to QoS prediction from the NWDAF by the server. The request includes a QoS requirement related to the QoS prediction.

Abstract: A disclosure of the present specification provides a method for accessing another Public Land Mobile Network (PLMN) instead of a subscribed third PLMN. According to the method, a terminal may access a second PLMN, which provides a service, instead of a first PLMN that is roaming-agreed with the third PLMN. In addition, according to the method, the terminal may display, on a screen, information indicating that access is made to the second PLMN. The second PLMN may provide only a limited service.

Abstract: A method and apparatus for sidelink connection suspension or release based on different target qualities of different services in a wireless communication system is provided. A first wireless device determines a first target cell quality for a first service related to a first bearer and a second target cell quality for a second service related to a second bearer. The first wireless device suspends at least one of the first bearer and/or the second bearer based on that a result of the measurement on a sidelink connection does not meet at least one of the first target cell quality and/or the second target cell quality. The first wireless device releases the sidelink connection if there is no more service using the sidelink connection.

Abstract: Provided is a method for managing a local area data network (LADN) session, as well as a session management function (SMF) node that is capable of performing this method. The method involves determining whether to release or deactivate the LADN session of a terminal based on information received by the SMF from an access and mobility management function (AMF) node. The information includes location information relating to the terminal and information as to whether the terminal is de-registered from a 3GPP access network. If the terminal is instead connected via a non-3GPP access network, the method helps avoid terminal location inaccuracies typically associated with non-3GPP access networks.

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: A disclosure of the present specification provides a method for processing a NAS request message by an MMF node. The method may comprise the steps of: when it is identified that an NAS request message has been received through a second access network, checking whether a first MM context and a first security context are included therein; and acquiring a second security context from an authentication CP node, and generating a second MM context.
