摘要
首先介绍了TDD LTE-A和WiMAX-A的研究背景,同时对垂直切换的原理进行了分析。在此基础之上,提出了一种基于TDD LTE-A与WiMAX-A实际特点的切换方案,给出了二者相互切换的流程,并利用Matlab仿真。最后,结合仿真结果论证了所提方案在一定程度上降低了垂直切换中"乒乓效应"的结论。
This article introduces related research background of TDD LTE-A and WiMAX-A, meanwhile, it analyzes thetheory about vertical handoff. Based on actual characteristic of these two heterogenous networks,it puts forward a strategy for vertical handoff, and designs aprocess for switching between LTE-A and WiMAX-A.At last, Matlabsimulation resuits shows that this hand off scheme can reduce the ＂ping-pong effect＂ effectively.
