  • Publication number: 20230319542
    Abstract: 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.
