摘要
语音业务仍然是5G时期的重要业务之一,3GPP标准已明确基于IMS网络为5G用户提供语音业务。结合5G网络部署路线的选择,本文分析了不同路线选择下的5G语音业务解决方案,以期为运营商在网络部署时提供参考。
Voice service is still one of the important services in the 5G period. The 3 GPP standard has clearly provided voice services for 5 G users based on the IMS network. Combining the choice of 5G network deployment route, the 5G voice service solution under different route selections is analyzed, in order to provide reference for operators in network deployment.
