    摘要： A mobile communication system includes an OpenFlow network and CSCFs. A first CSCF comprises a terminal information assigning unit that assigns information of an incoming terminal of a destination of a signal accommodated in a second CSCF to a header part of a signal destined for the second CSCF. The OpenFlow network comprises a storage unit that stores a correspondence relationship between the incoming terminal and a device accommodating the incoming terminal, a terminal information acquisition unit that acquires information of the incoming terminal from the header part of the signal, a transmission destination identification unit that identifies the device that is a transmission destination from the information, and an open flow transmission unit that transmits a signal to the identified device.
