WCDMA系统内小区重选参数影响研究

Impact of Cell Reselection Parameters on WCDMA System

WCDMA系统内小区重选参数包括:Treselection(小区重选触发时间)、Qhyst2(小区重选迟滞)、Qoffset2(小区重选偏移).通过对测试小区的小区重选参数Treselection、Qhyst2、Qoffset2分别设置不同的数据,通过路测来分析其不同影响,测试结果表明当Treselection、Qhyst2、Qoffset2参数设置不同时,其对小区重选边界、小区Ec/No、小区重选次数有比较明显的影响.

Cell reselection parameters in WCDMA system include Treselection, Qhyst2 and Qoffset2 three parameters. Different data are set by the cell reselection parameters Treselection, Qhyst2 and Qoffset2 in the test cell and the different effects are analyzed by the road test. The results show that when Treselection, Qhyst2 and Qoffset2 parameter settings are different at the same time,it has a significant effect on the cell reselection boundary, ceu Ec/No and the number of cell reselection.
