摘要
切换成功率是考核网络性能的一个重要指标,通常全网切换成功率应保持在95%以上。切换失败主要分为两部分:切换准备失败和切换执行失败。对于切换准备失败,BSC内的原因主要有目标小区拥塞、硬件问题等。对于跨MSC的切换,涉及E口信令转换,交换切换数据,编码方式沟通等原因,需要信令跟踪分析定位。而切换执行失败,原因主要有无线环境、参数设置、小区硬件故障等。
Success rate of switching is an important index to evaluate the network performance, usually the success rate of whole network handover should be maintained at more than 95%. Switching failure is mainly divided into two parts： switching preparation thilure and switching execution failure. To failure for switching preparation, there are two reasons in BSCas the target cell is crowed and the hardware problems, etc. For reasons of switching cross MSC, involving the E port signaling switching, exchange switching and communication of encoding method, it needs signal to track, analyze positioning.As for failure to switching execution, it mainly dues to the wireless environment, parameter setting, small hardware failure and so on.
