A switching device in a digital unit of a multi-sector base station, which uses switching elements incorporated in the digital unit and adapted to switch 3 sectors into multiple sectors, thereby being capable of implementing a multi-sector base station system allowing a softer handoff among all sectors. The switching elements are adapted to support the switching of the next channel element stage in the digital unit included in the existing 3-sector base station to implement a base station system, thereby allowing all handoff between sectors to be conducted in a softer handoff fashion while allowing all channel elements to be set for all sectors covered by the base station upon setting a traffic channel, thereby achieving an efficient allocation of channel elements. In accordance with the present invention, a 6-sector base station system is efficiently implemented in accordance with the setting of a timing capable of supporting an addition of switching elements, an operation of switching elements upon setting pilot, sync, and access channels, and an operation of switching elements upon a handoff and call setting. Since one digital unit can support 6 sectors, the overall configuration of the multi-sector base station system can be simplified and easily made.
