Abstract: An information processing device includes at least one network function among network functions disposed in each of two non-public cellular closed networks connected to each other by secure communication. The network function acquires information related to a communication device connected to the non-public cellular closed network of an own side or a counterpart side, and perform, based on the acquired information, processing related to packet arrival from the communication device connected to one of the two non-public cellular closed networks to the communication device connected to the other of the two non-public cellular closed networks.

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.

Abstract: The present technology relates to a network control device to flexibly control, at low cost, allocation of a user plane to a terminal in order to secure throughput according to the number of terminals in a network. The network control device includes a setting information holding unit and a control unit. The setting information holding unit holds, for each terminal, setting information including setting of a correspondence relationship with a user plane of a network. The control unit controls, after the setting of a correspondence relationship between a terminal and a user plane is changed, the network with the setting reflected under a predetermined condition.
