摘　　要：以改善4G用户体验速率为导向,以网格吞吐率模型为依据,当用户数增加不能够带来吞吐率增加为拐点,就需要考虑拆分SFN小区为独立RRU小区。反之,当独立小区的用户数少、吞吐率低、干扰严重、频繁切换时,需要考虑将独立RRU小区组合成为SFN小区,制定动态SFN组合与拆分评估策略,将人工的这种优化转化为自动的优化,节省运维成本。Guided by the improvement of 4G user experience rate and based on the grid throughput model,the SFN cell should be divided into an independent RRU cell when the increase of the number of users does not bring the increase of throughput as the inflection point.On the contrary,when the number of users in the independent cell is small,the throughput rate is low,the interference is serious,and the switch is frequent,it is necessary to consider the combination of independent RRU cells into SFN cells,develop dynamic SFN combination and split evaluation strategies,and transform the artificial optimization into automatic optimization,so as to save operation and maintenance costs.
