A common C-Plane control node includes a change request acquiring unit that acquires a change request relating to changing of a communication path relating to a UE, a determination unit that determines whether or not the UE has set up the communication path in each of control nodes of a plurality of slices using information included in the change request acquired by the change request acquiring unit, and a communication processing unit that performs a process relating to changing of a communication path while forming a state in which the communication path before change and the communication path after change coexist for each of a plurality of communication paths in a case in which the determination unit determines that the UE has set up the communication path in each of the plurality of slices.
