为了解决5G移动网络中能耗、用户移动性和移交(HO)问题，在研究了异构网络模型、功耗模型、用户及基站连接规则、用户移动模型及切换策略基础上，设计了一个双层异构网络模型。此外，为解决基站切换时可能导致负载不平衡和基站的收益降低等问题，提出了一个适用于HetNets的自适应负载平衡切换算。该算法允许用户在基站的估计负载超过一定阈值时进行自适应切换，从而平衡了基站间的负载，减少了网络中产生的干扰量。通过仿真分析，所提出的方法在在“开—关切换”情况下的平均基站数少于传统切换算法，在5 m/s的速度下的性能高达40%左右。

In order to solve the problem of energy consumption and mobility in 5 G mobile network, a two-layer heterogeneous network model is designed based on the study of heterogeneous network model, power consumption model, user and base station connection rules, user mobility model and handover strategy. In order to solve the problems of load imbalance and base station revenue reduction during base station handover, this paper proposes an adaptive load balancing switch conversion for HetNets. The algorithm allows users to switch adaptively when the estimated load of base stations exceeds a certain threshold, by balancing the load between base stations and reducing the amount of interference in the network. Through the simulation, the average number of base stations in the “on-off handover” situation is less than that of the traditional handover algorithm, and the performance is about 40% higher at the speed of 5 m/s.
