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 method for timer T adjustment due to disaster roaming occurrence, and an apparatus for supporting same. A user equipment (UE) determines that a disaster condition applies to a home public land mobile network (HPLMN). Upon selecting a disaster roaming PLMN, the UE performs a first registration procedure for disaster roaming services on the disaster roaming PLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a first value. Upon selecting a Visited PLMN (VPLMN), the UE performs a second registration procedure on the VPLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a second value.

Abstract: Provided is a method for controlling congestion caused by a disaster roaming user and a device supporting same. When a disaster occurs in a first public land mobile network (PLMN) that provides a service in a specific area, a user equipment (UE) performs registration with a second PLMN that provides a service in the specific area, and receives a message from a network in the second PLMN. The message includes: (i) information indicating that the UE is subject to congestion control in the second PLMN on the basis of the application of a disaster condition in the first PLMN; and (ii) timer information related to the congestion control. The UE operates a timer on the basis of the timer information, and performs PLMN selection with respect to a PLMN other than the second PLMN while the timer is running.

Abstract: Provided are a method for notifying of a disaster situation by a radio access network (RAN) node, and a device supporting same. When the RAN node detects that a problem in an interface between cores networks related to a public land mobile network (PLMN) has occurred, the RAN node stops transmitting a broadcast message currently being transmitted to a user equipment (UE), and transmits a disaster broadcast message to the UE. The disaster broadcast message comprises: (i) information indicating that a disaster condition is applied to a first PLMN; and (ii) information on a second PLMN related to the disaster condition. The disaster condition corresponds to a problem in an interface between the RAN node and a core network related to the first PLMN. The UE adjusts priorities of an PLMN selection on the basis of information included in the disaster broadcast message, and selects the second PLMN according to the adjusted priorities.

Abstract: One disclosure of the present specification provides a method by which a network allows user equipment (UE) to communicate. The method comprises the steps of: receiving, from the UE, a registration request message including a provision request for a specific network slice; determining whether the network can provide a service for the specific network slice to the UE, on the basis of i) the registration request message, ii) the specific network slice, iii) subscription information and the like about the UE; and transmitting a response message to a base station on the basis of the network not being able to provide the service for the specific network slice to the UE, wherein the response message includes information about the rejection of the provision request for the specific network slice, and the response message can include network slice support information related to the specific network slice.

Abstract: One embodiment of the present specification provides a method by which a UE performs communication related to a network slice. The method may comprise the steps of: transmitting, to an access and mobility management function (AMF) node, a first registration request message including information about a first network slice which the UE wants to access; receiving, from the AMF node, a response message including candidate network slice information; and displaying, on the basis of information about the candidate network slice, on the display of the UE, information indicating that the first network slice cannot be accessed.
