METHOD FOR CONTROLLING BASE STATION'S LOAD BASED ON ADAPTIVE RADIO TRANSMISSION TECHNOLOGY

摘要

PURPOSE: A load control method of a base station based on an adaptive wireless transmission method is provided to control a load in a base station. CONSTITUTION: A monitoring unit measures a load of a base station(S101). A comparison unit compares the load with a defined threshold(S103). A load control unit changes an operation of a first wireless unit corresponding to the comparison from the comparison unit(S107,S113). The load control unit controls the load of the base station(S111,S117). The first wireless unit transmits a wireless signal to the base station. The first wireless unit is operated by receiving a digital signal from the base station.
