    Abstract: A method of receiving, by a user equipment (UE), a paging signal in a wireless communication system is disclosed. More specifically, the UE performs a registration to a plurality of networks, obtains a plurality of monitoring time points that has to check whether a paging message is received from each of the plurality of networks, when at least some of the plurality of monitoring time points overlap, transmits, to a first network, a change request of a first monitoring time point that has to check whether a first paging message is received from the first network of the plurality of networks, receives, from the first network, configuration information related to the request, and updates the first monitoring time point based on the configuration information.

    Abstract: A method for performing, by a user equipment (UE), a registration to a network in a wireless communication system is disclosed. Specifically, the UE performs a registration to a first public land mobile network (PLMN) via a first base station, receives an disaster related message applied to the first PLMN or applied to an area in which the UE is located when there is no service provided from the first PLMN, transmits a registration request message to a second PLMN providing an disaster roaming service based on the disaster related message, and receives, from the second PLMN, a response message to the registration request message. The UE is subscribed to the first PLMN, and the second PLMN is configured to provide the disaster roaming service to the UE based on a disaster applied to the first PLMN or applied to the area in which the UE is located.

    Abstract: A disclosure according to the present specification provides a method of having an access by a terminal subscribing to a first public land mobile network (PLMN). The method may comprise a step of transmitting a first request message to a network node via 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 of receiving, from the network node, a first response message that is a response to the first request message. The first response message may include information indicating that there is a service failure in the first PLMN. The method may comprise a step of transmitting a second request message to the second PLMN or reselecting another PLMN instead of the first PLMN, which has a service failure, on the basis of the first response message including the information.

    Abstract: One disclosure of the present specification provides a method by which a first network node performs communication on the basis of multiple USIMs. The method can comprise: receiving, from UE, a registration request message including MT service configuration information; receiving, from the UE, information informing that the UE leaves a first network including the first network node; receiving, from a second network node, information related to downlink data about the UE; and transmitting a paging message or a failure indication on the basis of the MT service configuration information and the information related to the downlink data.

    Abstract: Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

    Abstract: According to an embodiment of the present invention, a method for selecting a public land mobile network (PLMN) by a user equipment (UE) in a wireless communication system comprises: in a manual network selection mode, displaying one or more first PLMN items corresponding to one or more first PLMNs on a display of the UE; when an input for a second PLMN item among the one or more PLMN items is received, controlling a communication module of the UE to attempt to register the UE on a second PLMN corresponding to the second PLMN item; when the registration on the second PLMN fails, providing access to restricted local operator service (RLOS), and displaying, on the display, one or more third PLMN items corresponding to one or more third PLMNs included in an RLOS PLMN list configured in a universal subscriber identity module (USIM) of the UE; and when an input for a fourth PLMN item among the one or more third PLMN items is received, controlling the communication module to initiate registration for access to the RLOS of a fourth PLMN corresponding to the fourth PLMN item, whereby it is possible to use not only excellent but also highly secure RLOS.
