摘要： A communication device (100) which operates as an application node which executes one or a plurality of applications includes: a communication unit (110) that executes communication with another logical node; and a control unit (130) that controls communication by the communication unit (110). The another logical node is a node which is applied with application function chaining (AFC) in which, in transmission/reception of an application message with the application node as a transmission source or a transmission destination, one or a plurality of application functions act on the application message midway along a path of the transmission/reception, and the control unit (130) causes the communication unit (110) to transmit, to the another logical node, a message according to a publishing/subscription model in order to transmit and receive the application message on which the one or the plurality of application functions act.

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.-
