Abstract: Provided are a method for managing a prohibited PLMN list during disaster roaming, and an apparatus supporting same. User Equipment (UE) determines, when there is no available public land mobile network (PLMN) other than PLMNs included in a first list, whether the PLMNs included in the first list can provide a disaster roaming service, and includes in a second list at least one PLMN that can provide the disaster roaming service, from among the PLMNs included in the first list. On the basis that a disaster condition is applied to a home PLMN (HPLMN), the UE i) performs PLMN selection for the at least one PLMN included in the second list, and ii) selects a disaster roaming PLMN from among the at least one PLMN and receives the disaster roaming service provided from the disaster roaming PLMN.

Abstract: Provided are a method for adjusting timer T when disaster roaming occurs, and a device supporting same. When a disaster condition is applied to a home public land mobile network (HPLMN), a user equipment (UE) performs registration with a disaster roaming PLMN. When the registration with the disaster roaming PLMN is performed, a timer for periodically searching for the HPLMN does not operate, and the HPLMN is not searched while the timer does not operate. In addition, the UE re-operates the timer on the basis of the disaster condition no longer being applied to the HPLMN or the UE leaving a disaster area.

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 disclosure of the present specification provides a method for performing, by relay UE, communication related to a configuration update. The method comprises the steps of: receiving, from a network node, a configuration update command message including information requesting to perform a registration procedure; and transmitting, to the network node, a response message to the configuration update command message, wherein the response message includes information requesting to maintain a NAS signaling connection between the relay UE and the network node.

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.

Abstract: A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.
