摘　　要：5G网络中大规模基站的部署以及大规模的移动终端接入基站使得QoS严重弱化.针对QoS弱化问题,文章根据参与组网的基站属性以及接入终端的差异化特征设计了动态的备选基站库用于重构虚拟网络.重构后的网络在应对大规模移动终端接入时不仅提升了接入容量、提高全网服务速率,同时低复杂度的算法特征也能高效缓解系统噪声干扰对QoS造成的影响.实验结果表明,该虚拟网络重构技术在应对大规模基站部署和大规模移动终端接入时具备良好的科学性.The deployment of large-scale base stations in 5G network and the access of large-scale mobile terminals to base stations seriously weaken the quality of service(QoS)of the whole network.Aiming at the problem of QoS weakening,according to the real-time state differentiation characteristics of individual base stations and individual mobile access,a dynamic alternative base station library is designed to reconstruct the virtual network.When dealing with large-scale mobile terminal access,the reconstructed network not only improves the access capacity and the service rate of the whole network,but also effectively mitigates the impact of system noise interference on QoS due to the low complexity of the algorithm.The investigation data show that the virtual network reconfiguration technology has scientific response ability when deployed in the network situation of large-scale base station and large-scale mobile terminal access.
