A base station system configured to connect a plurality of base station functional units and a plurality of antenna units disposed in a plurality of provision areas via an optical fiber section, wherein the plurality of base station functional units are configured to provide a plurality of radio schemes, the base station system comprising:

a plurality of passive light functional units disposed between the plurality of base station functional units and the plurality of antenna units, wherein a first passive light functional unit among the plurality of passive light functional units includes a plurality of downlink signal output ports to which a plurality of downlink signal wavelengths are allocated and a plurality of uplink signal output ports to which plurality of uplink signal wavelengths are allocated;
and
an optical switch disposed between the plurality of antenna units and the plurality of passive light functional units, configured to accommodate a particular radio scheme among the plurality of radio schemes, and switch to a particular provision area among the plurality of provision areas where the particular radio scheme is provided.

A base station control method performed in a base station system, the method comprising:

requesting a base station control device to switch to a particular provision area where a particular radio scheme is provided;
causing an optical switch to switch to the particular provision area where the particular radio scheme is provided and notifying of the switching;
notifying that the base station control device has switched to the particular provision area where the particular radio scheme is provided;
requesting, by the base station control device via a base station functional unit that provides the particular radio schemes, an antenna unit in the particular provision area where the particular radio scheme is newly provided to set an uplink signal wavelength;
requesting, by the base station functional unit, the antenna unit in the particular provision area to set the uplink signal wavelength;
setting, by the antenna unit in the particular provision area, the uplink signal wavelength and notifying the base station functional unit of the setting;
notifying, by the base station functional unit, the base station control device that the uplink signal wavelength has been set in the particular provision area.
