Stepwise Evaluation Based 5G gNB Intelligently Closing Algorithm
Based on the amount of allocated physical resource blocks(PRBs),the efficiency factor of PRB is calculated.Combining with 5G gNB's load,a three-level stepwise evaluation method is introduced to obtain the closing candidate sets(CCSs).On the premise of capacity threshold,the method checked the neighbor sets of gNBs'CCS,and then the load space is counted,and only when the load space meets the demand,the base station shutdown behavior will be triggered.The set of neighboring cells to be shut down for the base station is calculated,and its transfer load is also calculated,after the neighboring area trans-fer operation is completed,the source base station is shut down.At last,the algorithm is simulated and validated by Matlab,and the results show that both single station shutdown and cluster shutdown can effectively improve the shutdown efficiency of the original algorithm,achieving ideal energy-saving goals.
