摘要
Abstract
How to ensure that VoLTE calls maintain without breaking up when switching from 4G to 2G/3G is a key problem in VoLTE technologies. This paper introduced a signiifcant technology to solve this problem. SRVCC and its various types, and then analyzed eSRVCC, a more mature technology in SRVCC, and its associated signaling processes. Then VoLTE handover success rate algorithm was described, and the eSRVCC handover failure delimiting taxonomy was proposed based on the Sv interface. Lastly, the method was used to solve the problem of current network VoLTE handover failures. Practice results show that the eSRVCC handover optimization method based on failure delimiting taxonomy can quickly pinpoint surface investigation to the failing location, thereby improving eSRVCC optimizing efifciency for VoLTE network.关键词
