摘要

本文主要介绍了一种用于VoLTE (Voice over LTE)的增强域切换方案——eSRVCC。为了保证电信级的语音通话质量，该方案必不可少;特别是在从传统电路交换系统到基于全IP的EPS(演进分组系统)的网络迁移阶段。此外，本文还解释了在漫游场景下支持VoLTE的新机制。

Enhanced voice over LTE and its roaming aspects

This paper mainly explains an enhanced domain handover scheme for VoLTE (Voice over LTE) called eSRVCC. The scheme is essential in order to ensure the carrier-grade voice call quality; especially during the network migration phase from legacy circuit switched system to the All IP based EPS (Evolved Packet System). In addition, this paper explains the new mechanisms to support VoLTE in roaming scenarios.
