摘要
Abstract
Providing high deifnition voice and shorter time delay is the main advantage of VoLTE services, but due to the high frequency band of TD-LTE system, weak coverage is inevitable. To solve the problem, from the perspective of user perception, this paper discussed how to improve the quality of VoLTE calls in weak coverage scenarios, and put forward the optimization solutions for the wide area scene and the urban area.关键词
