掉话是指用户通信过程中发生异常释放，掉话率是评价CDMA系统性能的一项重要指标。一般来说，可以通过后台信令跟踪、前台信令分析等方法处理掉话问题，其中分析定点测试数据是解决掉话故障的直观方法。

The result indicated that the user complaint rate, call block rate, drop call rate and so like network performances are all improved after optimizing, further proved the feasibility of this subject.
测试结果表明,无论是路测指标还是用户投诉,拥塞率、掉话率、接通率、改善覆盖以及通话质量等指标都有较大的提高。 进一步验证了本课题的可行性。

切换成功率降低，将直接导致掉话的增加。
Cut over the success rate lower, will directly cause the increment of words.
该策略以少量的效用代价换取较低的切换掉话率。
The proposed scheme has the lower handover call probability at the cost of little utility.
这也就是为什么通话当中有时会出现掉话或音质差的原因。
So sometimes that’s why calls get dropped or why you get poor quality.
