摘　　要：针对5G微站应对多量级移动接入存在服务质量(QoS)弱化的问题,构思一种全网状态评估机制用于微站自适应重构。重构方案首先根据QoS约束模型获得能效目标函数,再基于排序机制为微站划分簇群净化噪声,同时引入自适应权重和调整策略以进一步提升微站重构能力;然后为不同规模的簇群分别规划微站选项,为移动接入提供错峰受理服务。测试结果表明,该自适应重构方案有助于提升5G环境下的QoS。To tackle the problem of the weakening of quality of service(QoS)of 5G microstation in dealing with multi-level mobile access,a whole network state evaluation mechanism is conceived for microstation adaptive reconfiguration.Firstly,the reconstruction scheme obtains the energy efficiency objective function according to the QoS constraint model,and then divides the microstation into clusters based on the sorting mechanism to purify the noise.At the same time,the adaptive weight and adjustment strategy are introduced to further improve the reconstruction ability of the microstation.Then,microstation options are planned for clusters of different sizes,and peak shifting acceptance services are provided for mobile access.The test result shows that the adaptive reconfiguration scheme is helpful to improve the QoS in 5G environment.
