摘　　要：随着当前LTE网络的日趋成熟,网络用户的渗透率逐年提高。在现网有限的资源里,如何最大化资源利用率来提升现网的用户感知,是当前LTE网络建设优化中值得思考的问题。因此,以有效发挥低频段覆盖层能力和高频段话务吸收能力为目标,探讨优化单一频段和多频段互操协同的多频段组网策略:合理使用1.8G/2.1G网络带宽资源的保护间隔,通过调整800M小区PA/PB来提升CQI≥7的小区占比;通过调整切换事件的门限指标,对不同场景进行多频协同优化,从而降低现网超忙小区的网络负荷等。With the current LTE network becoming more and more mature,the penetration rate of network users is also increasing year by year.In the limited resources of the current network,how to maximize the utilization rate of resources to improve the user perception of the current network is a problem worthy of consideration in the current LTE network construction optimization.In this paper,the goal is to effectively play the low-frequency coverage and highfrequency traffic absorption capabilities,to explore the optimization of single frequency band and multi-band interoperability and cooperation of multi-band networking strategy,to improve the online experience of users in the network at each frequency point.The main strategies include:reasonable use of 1.8g/2.1g network bandwidth resource protection interval,increasing the cell proportion of CQI≥7 by adjusting the PA/Pb of 800m cell,multi frequency collaborative optimization of different scenarios by adjusting the threshold index of switching events,so as to reduce the network load of the current network’s busy cell,etc.
