摘要
为适应LTE SON减少人工参与、降低运营成本(OPEX)的要求,针对网络不能动态调整参数、自主规划基站位置的情况,设计出了一种LTE下根据业务量的变化动态调整eNB参数的自规划流程,并最终计算出新建eNB的位置坐标。通过仿真对其进行了衡量和分析,结果表明在该坐标新建一个eNB不仅能够使业务量溢出的eNB得到极大的缓解,还能使新建eNB附近的小区负载达到更加均衡的状态。
To meet the requirements of reducing human intervention and operational expenditures（OPEX） of LTE SONs（Self-organizing Networks）, and according to the situation that networks can＇t adjust the parameters dynamically and plan the location of base station automatically, a self-planning flow in LTE is designed which can adjust the parameters of eNB dynamically according to the changes of the traffic and the location of the new eNB can be calculated. This mechanism is measured and analysed by simulation and the results show that building a new eNB at the location calculated can not only ease the eNBs of which the traffic has overflowed, but also a more balanced state of the load of the cells near the new eNB can be achieved
