AS a mainstream voice solutions for TD-LTE network in China Mobile currently, CSFB related to 2G/3G/4G network with multiple network elements, the process is complex and involved in many factors. Firstly, the terminal boot resident, call set-up, hang up and return, abnormal delay is analyzed in this 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.
