摘　　要：4G、5G移动通信网络迅猛发展,业务类型较多,无线数据传输速率直接影响用户体验。用户移动过程中,小区间的硬切换会影响数据传输效率,频繁的乒乓切换会恶化用户感知体验。实际网络中无线参数配置不当导致的乒乓切换,当前还缺乏快速有效的判断方法。本文通过构建切换关系有向图的方法,支持快速有效地检查多个小区间存在复杂切换关系情况下的参数配置是否合理,有效解决乒乓切换问题,提升无线网络性能。With the rapid development of 4G and 5g mobile communication networks and many types of services,wireless data transmission rate directly affects user experience.In the process of user movement,hard handoff between cells will affect the efficiency of data transmission,and frequent ping-pong handoff will worsen the user experience.The ping-pong handoff caused by the improper configuration of wireless parameters in the actual network is still lack of fast and effective judgment methods.In this paper,by constructing the directed graph of handoff relationship,we can quickly and effectively check whether the parameter configuration is reasonable in the case of complex handoff relationship between multiple cells,effectively solve the problem of ping-pong handoff,and improve the performance of wireless network.
