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: 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.

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.
