    摘要： To detect and recover from failure occurring in a core network.
    A subscriber information holding unit holds subscriber information indicating association between a terminal and a user plane function in a communication system. A failure detection unit detects a failure related to the user plane function. A control unit changes the subscriber information held in the subscriber information holding unit so as to associate a new user plane function with the terminal associated with the user plane function in which the failure is detected by the failure detection unit.

    摘要： 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.
