摘要： Signal transfer devices that relay base stations of service providers that perform communication with radio terminals and an aggregation station that controls the base stations, and a route control device that controls signal distribution to user network interfaces (UNIs) and network network interfaces (NNIs) of each of the signal transfer devices, are included. The route control device includes an allocation information acquisition unit that acquires allocation information of frequency to each of the base stations; a band adjustment unit that adjusts an MBH band for each of the UNIs, on the basis of correspondence relation information representing a correspondence relation between the UNIs and the service providers, band information indicating a maximum MBH band of each of the UNIs, and the allocation information; and a distribution determination unit that determines signal distribution to each of the NNIs, on the basis of the MBH band adjusted by the band adjustment unit and configuration information representing a connection configuration of each of the signal transfer devices. The signal transfer device transmits a signal from each of the NNIs on the basis of the signal distribution to each of the NNIs determined by the distribution determination unit.
