摘要
Abstract
China's current VoLTE service has been able to provide reliable communication support for users in large networks.However, the service quality of VoLTE services in the HSR scene with special requirements for network transmission is still quite different from that of the big network.This article analyzed the main factors which affect VoLTE voice quality MOS value in HSR scene to further improve the voice service quality of VoLTE in HSR (High Speed Rail) scenarios, proposing the idea of optimizing voice quality of VoLTE.It studied and analyzed key parameters of VoLTE wireless optimization, analyzed effects of different key parameters on VoLTE voice quality in HSR scenarios through experiments, and proposed an improved modification scheme of key parameters, which proved that using the modified key parameters can get better voice quality.关键词
