1. A base station system, comprising:
a plurality of first units each having at least a radio resource scheduling function among functions of a base station, and each being used to provide one or more slices;
a plurality of second units connected with respective first units among the plurality of first units, wherein each of the plurality of second units is connected between a corresponding first unit of the plurality of first units and a core network, and has, among the functions of the base station, a upper layer function than a function that the corresponding first unit has; and
one radio unit having at least a radio wave transmission/reception function among the functions of the base station, and deployed at an antenna site,
wherein the one radio unit is connected with the plurality of first units, and a plurality of slices provided via the plurality of first units are provided in the same cell formed by the one radio unit.
