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: 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 for supporting service continuity when a disaster situation ends, and a device supporting same. A user equipment (UE) receives, from a disaster roaming PLMN, a configuration update command message including information indicating that a disaster condition of a home PLMN (HPLMN) has ended. The UE waits until a service that is being received from the disaster roaming PLMN ends, and performs, after the service that is being received from the disaster roaming PLMN ends, a procedure of deregistration from the disaster roaming PLMN on the basis of information indicating that the disaster condition of the HPLMN has ended.

Abstract: A disclosure of the present specification provides an operating method for user equipment (UE) supporting a multiple universal subscriber identity module (USIM). The operating method may comprise the steps of: transmitting, by the UE, a first radio resource control (RRC) message to a first radio access network (RAN) in a first network; and receiving, by the UE, a second RRC message from the first RAN. The first RRC message may be transmitted on the basis of determination that the UE moves from the first network to a second network. The first RRC message may include first information about one or more protocol data unit (PDU) sessions established via the first RAN. The first and second RRC messages may be used to change an RRC state to an RRC idle state or an RRC deactivated state.

Abstract: A method for controlling a data transmission state by a terminal in a wireless communication system may comprise: transmitting capability configuration information of the terminal to a node of a network; applying a triggered communication environment configuration on the basis of the capability configuration information from the node; transmitting, to the node, first connection configuration information related to a wireless local area network (WLAN) connection configuration; and applying a first communication environment reconfiguration triggered from the node on the basis of the first connection configuration information, wherein the capability configuration information includes LWA function permission information of the terminal.

Abstract: A disclosure of the present specification provides a method performed by a network node that manages mobility in a first public land mobile network (PLMN). The network node may receive an access request message of a terminal from a base station in the first PLMN. The terminal may be a terminal having joined a second PLMN. On the basis of occurrence of a failure in the second PLMN, the network node may determine whether to allow the terminal to roam to the first PLMN.

Abstract: In a wireless communication system, when a remote user equipment (UE) accesses a network via a relay UE, a base station provides an identifier of a mobility management entity (MME; relay UE MME) of the relay UE to an MME (remote UE MME) of the remote UE. When paging for the remote UE is required while the remote UE is connected to a network via the relay UE, the remote UE MME transmits a request for paging for the remote UE to the relay UE MME, and the relay UE MME transmits a paging notification to the relay UE or starts a paging process for the relay UE through the base station.

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: Provided is a method for a terminal for carrying out access control according to one disclosure of the present specification. The method may comprise the steps of: an access stratum (AS) layer of the terminal transmitting, to a base station, a radio resource control (RRC) message comprising one or more from among an access category, call type, and setup reason if the determination is for no disconnection to occur as a result of carrying out a termination test for access control; and receiving an RRC reject message or RRC connection drop message from the base station if the network is overloaded or congested. One or more from among the access category, call type, and setup reason included in the RRC message can be utilized to determine whether the base station is to transmit the RRC reject message or RRC connection drop message when the network is overloaded or congested.
