摘　　要：提出一种基于仿真测试平台的TD-LTE多模终端CSFB性能测试方案。该方案采用主控制器与多系统模拟器相结合的硬件架构,由系统模拟器真实模拟TD-LTE/TD-SCDMA/GSM多制式的网络环境,主控制器通过执行脚本文件控制具体的测试流程。实例测试结果表明,该方案能够准确测量CSFB呼叫时延等参数,从而直观地反映被测终端的性能水平。In order to carry out CSFB performance testing for TD-LTE multi-mode terminals,a simulation test platform is proposed.The test system adopts the hardware structure which combines a main controller and several multi-system simulators,in which system simulators are used to simulate TD-LTE/TD-SCDMA/GSM multi-standard wireless network environments and the main controller is used to control test process by executing script files.Test results show that the system can accurately measure parameters such as CSFB call delay to intuitively reflect performance levels of terminals.
