Abstract: One disclosure of the present specification provides a method for a user equipment (UE) to access a non-public network (NPN). The method may comprise: a step for selecting a first public land mobile network (PLMN); a step for, when the UE is configured to use the NPN, determining whether the NPN is available in a first cell of the first PLMN on the basis of NPN-related configuration information; a step for, when it is determined that the NPN is available in the first cell of the first PLMN, attempting to access the first cell in the first PLMN; and a step for, when it is determined that the NPN is not available in the first cell of the first PLMN, not attempting to access the first cell in the first PLMN.

Abstract: A method for performing, by a user equipment (UE), a registration to a network in a wireless communication system is disclosed. More specifically, the UE performs a registration to a first public land mobile network (PLMN) via a first base station, receives a disaster related message indicating that a disaster roaming service is provided, checks whether the UE is provided with the disaster roaming service based on the disaster related message, selects a second PLMN providing the disaster roaming service when the UE is provided with the disaster roaming service as a result of the check, transmits a registration request message to the selected second PLMN based on the disaster related message, and receives, from the second PLMN, a response message to the registration request message.

Abstract: Disclosed are a method for accessing a network by user equipment in a wireless communication system and a device therefor. More specifically, a method for accessing a network by user equipment (UE) in a wireless communication system comprises the steps of: receiving access information regarding access identity and access category values that are valid in a cell in which the UE is camping; selecting, when an access attempt is made to the network, values associated with the access attempt from the access identity and access category values that are valid in the cell on the basis of the access information; and performing an access barring check on the basis of the selected access identity and access category values, thereby enabling access to the network.

Abstract: Disclosed are a method of accessing a network in a wireless communication system and an apparatus therefor. Specifically, a method of accessing a network by a user equipment (UE) in a wireless communication system may include receiving, from the network, a skip condition for an access barring check operation for a cell supported by a base station, determining whether the UE satisfies the skip condition for the access barring check operation, determining that access to the network on the cell has not been barred when the skip condition for the access barring check operation is satisfied, and performing the access to the network on the cell without performing the access barring check operation.

Abstract: In a wireless communication system of the present disclosure, when activation of a protocol data unit (PDU) session of a user equipment (UE) is needed, the UE performs an access control check to determine whether an access attempt for the PDU session is allowed. If the access attempt is allowed, the UE transmits a service request for the PDU session. The access control check for the PDU session is performed even if the UE is in a connected state.

Abstract: In a wireless communication system, a user equipment (relay UE) can request to connect to a network to transfer data to another user equipment (remote UE). Before requesting the connection, the relay UE can perform access control for determining whether an access attempt to the network is allowed. The relay UE can perform the access control by using an access class of the remote UE.
