【摘要】：长期演进(LTE)网络是3GPP定义的先进移动网络系统,相比现有的2G和3G网络,LTE网络的用户(UE)更加密集、站间距更小、更多的小基站加入系统,从而使UE移动性管理面临更大的挑战。为此,提出了一种新型UE切换方法。仿真结果显示,新方法能够很好地解决密集LTE异构网络中UE切换失败率高的问题,性能优化显著。
[Abstract]:The long-evolving (LTE) network is an advanced mobile network system defined by 3GPP. Compared with the existing 2G and 3G networks, the user (UE) of LTE network is more dense, the distance between stations is smaller, and more small base stations join the system. Thus, UE mobility management is faced with greater challenges. Therefore, a new UE switching method is proposed. Simulation results show that the new method can solve the problem of high UE handoff failure rate in dense LTE heterogeneous networks, and the performance optimization is significant.
