VoLTE是LTE时代全球运营商语音及语音漫游的主流方案,其采用SRVCC/eSRVCC支持语音业务连续性,可提供高质量音视频业务体验,为用户提供更为丰富的业务体验。

随着FDD和TDD的协同发展,越来越多的运营商正投入到VoLTE网络的部署与建设中。然而,VoLTE的部署涉及IMS核心网、EPC核心网、CS核心网、用户数据、信令网、无线网、承载网支撑系统等多个领域的相关问题,是对运营商网络与通信业务变革的一次重大挑战。此次网络研讨会我们将探讨:

  1. VoLTE服务验证和故障排除实例;
  2. 端到端VoLTE会话检测、问题识别和根源分析;      
  3. 如何使用被动分析仪在实时网络中分析VoLTE问题。
