1. A signal transfer system comprising:
a plurality of signal transfer devices that relay a plurality of base stations of a plurality of service providers that perform communication with radio terminals and an aggregation station that controls the plurality of the base stations; and
a route control device that controls signal distribution to a plurality of user network interfaces (UNIs) and a plurality of network network interfaces (NNIs) of each of the plurality of the signal transfer devices,
wherein the route control device includes:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
acquires allocation information of frequency to each of the base stations;
adjusts an MBH band for each of the plurality of the UNIs, on a basis of correspondence relation information representing a correspondence relation between the UNIs and the plurality of the service providers, band information indicating a maximum MBH band of each of the UNIs, and the allocation information; and
determines signal distribution to each of the plurality of the NNIs, on a basis of the adjusted MBH band and configuration information representing a connection configuration of each of the signal transfer devices,
wherein each of the signal transfer devices transmits a signal from each of the NNIs on a basis of the signal distribution to each of the determined NNIs.
