    Abstract: The present specification provides a method for processing, by an access and mobility management function (AMF) device in a first network, a request from a user equipment (UE). The method may comprise receiving, by the AMF device in the first network, a first request message from the UE that supports multiple universal subscriber identity modules (USIMs) and has received a paging message from a second network. The first request message may comprise information on one or more protocol data unit (PDU) sessions and information on release. The method may comprise transmitting a second message to a session management function (SMF) device in the first network. The second message may comprise information on the one or more PDU sessions based on the first request message. The method may comprise performing a procedure for releasing with a radio access network (RAN) in the first network.

    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: 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.
