| Abstract: | Abstract: LTE handover is based on signal coverage, which cannot effectively solve the signal quality problem caused by interference. This paper focuses on the optimization strategy of eSRVCC handover based on voice quality via quality judgment, which solves the poor signal quality problem in dense urban area and fast fading senario in rural area, therefore improves the voice quality a lot.
