Abstract: Provided are a method and a device for supporting generation of a dedicated protocol data unit (PDU) session for particular user traffic. A user equipment (UE) operating in a wireless communication system determines whether to establish a dedicated protocol data unit (PDU) session exclusively used for traffic matched to a particular traffic descriptor (TD), on the basis that a route selection descriptor (RSD) associated with the particular TD includes an indicator indicating whether to establish the dedicated PDU session. The UE requests a network to establish the dedicated PDU session on the basis of the determination of dedicated PDU session establishment.

Abstract: One embodiment of the present specification can provide a method for performing a protocol data unit (PDU) session-related procedure. The method can comprise the steps of: transmitting, to a session management function (SMF) device, a PDU session-related message including a first indication related to communication through a PC5 link; and receiving a response message from the SMF device. The response message can include: a first quality of service (QoS) rule to be used on a Uu link; a second QoS rule to be used on a PC5 link; and a path selection rule about whether data should be transmitted through the Uu link or the PC5 link.

Abstract: Provided are a method and a device for processing a network slice-specific authentication and authorization (NSSAA) failure caused by a network error or timeout. An access and mobility management function (AMF): starts an NSSAA procedure for an NSSAA function (NSSAAF) and single network slice selection assistance information (S-NSSAI); and restarts the NSSAA procedure after waiting for a certain period, on the basis that the Hypertext Transfer protocol (HTTP) status code “504 Gateway Timeout” is received from the NSSAAF, and/or a response regarding the NSSAA procedure could not be received from the NSSAAF.

Abstract: One disclosure of the present specification provides a method by which a terminal that joined a first public land mobile network (PLMN) performs a connection. The method may comprise a step for transmitting a first request message to a network node through a base station. The base station may be a base station of a second PLMN that broadcasts system information including information about the first PLMN. The method may comprise a step for receiving, from the network node, a first acceptance message for the first request message. The first acceptance message may include information indicating that there is a service failure in the first PLMN. The method may comprise a step for displaying, on a screen of the terminal, information indicating that the terminal is connected to the second PLMN on the basis of the information.

Abstract: According to one disclosure of the present specification, provided is a method in a network node that manages mobility in a second public land mobile network (PLMN). According to the method, an access request message from a terminal may be received through a base station in the second PLMN. In addition, a response message to an access request of the terminal may be transmitted. The response message may include information indicating rejection to the access request of the terminal, on the basis of the terminal that joined a third PLMN and on the basis of the base station that transmitted system information including information about a first PLMN on behalf of a base station of the first PLMN.
