摘要
CSFB方案作为目前中国移动TD-LTE网络主流的话音解决方案,涉及2G/3G/4G网络多个网元,流程复杂、影响因素众多,本文首先对终端开机驻留、呼叫建立、挂机返回及时延异常等常见问题进行了梳理分析,然后详细阐述了CSFB呼叫时延、被叫成功率两大关键指标的优化措施,对于指导CSFB优化工作开展具有较好的参考价值。
AS a mainstream voice solutions for TD-LTE network in China Mobile currently, CSFB related to2G/3G/4G network with multiple network elements, the process is complex and involved in manyfactors. Firstly, the terminal boot resident, call set-up, hang up and return, abnormal delay is analyzed inthis paper, then elaborate the optimization measures for CSFB call delay and the rate of successful call,which has a good reference value for CSFB optimization work.
