Abstract

An object of the invention is to provide a communication service with high utilization efficiency. A mobile communication network distribution system includes: an acquisition unit that acquires condition information; a determination unit that determines a degenerate mobile communication network which provides a function satisfying a functional requirement based on the condition information acquired by the acquisition unit among a plurality of mobile communication networks to be a connection destination mobile communication network which is a connection destination of the UE; and a distribution unit that distributes the connection destination of the mobile communication terminal to the connection destination mobile communication network determined by the determination unit.

Claims
