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.
Claims15
A communication system comprising:
- a subscriber information holding unit that holds subscriber information indicating association between a terminal and a user plane function in a communication system;
- a failure detection unit that detects a failure related to the user plane function;
- and
- a control unit that changes the subscriber information to associate a new user plane function with the terminal associated with the user plane function in which the failure is detected.
A failure recovery method in a communication system including:
- a subscriber information holding unit that holds subscriber information indicating association between a terminal and a user plane function in the communication system, the method comprising:
- a procedure in which a failure detection unit detects a failure related to the user plane function;
- and
- a procedure in which a control unit changes the subscriber information to associate a new user plane function with the terminal associated with the user plane function in which the failure is detected.
