Signal transfer system, signal transfer method, and path control device

A signal transfer method using a plurality of UNIs and a plurality of NNIs of each of 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, the method comprising:

• an allocation information acquisition step of acquiring allocation information of frequency to each of the base stations;
• a band adjustment step of adjusting 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 representing a maximum MBH band of each of the UNIs, and the allocation information;
• and
• a distribution determination step of determining signal distribution to each 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.

A route control device that controls signal distribution to a plurality of UNIs and a plurality of NNIs of each of 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, the device comprising:

• 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 plurality 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 plurality of the signal transfer devices.
