Research and Verification of the Scheme to Ensure Voice Over Wi-Fi Call Quality

Operators' cellular networks have problems such as weak coverage, insufficient deep coverage, and high-level pilot pollution, which lead to poor voice call experience. The VoWiFi service can make up for the above problems caused by the cellular network. However, V oWiFi also has many factors that affect its call quality. When Wi-Fi data services and VoWiFi services occur at the same time, this paper proposes a method to suspend other Wi-Fi data services to ensure VoWiFi call quality according to service priority, and verifies the effectiveness of this method.
