Abstract
A hub apparatus may be provided for distributing a load of a small cell digital unit to a macro cell digital unit in a heterogeneous network. The hub apparatus includes an offloading controller configured to determine a first small cell, as an offloading target among a plurality of small cells based on a load of the macro cell digital unit and the small cell digital unit, to determine a first digital unit processing a load of the first small cell among at least one macro cell digital unit, to that generate a first control signal that requests connection to the first digital unit and a low-power radio unit of the first small cell, a path change unit connected to each of an antenna, having one side installed in the macro cell and a low-power radio unit installed in each small cell, having the other side connected to each of the macro cell digital unit and the small cell digital unit, configured to form a path connecting the one side and the other side, and configured to change a digital unit connected to a corresponding low-power radio unit based on the first control signal.
