摘　　要：阐述5G网络建网初期,语音问题主要采用EPSFallback的解决方案从NR网络回落到LTE网络,相应数据业务也在LTE网络进行。回落带了呼叫建立时延的增长以及通话时无法享受数据业务高速上网的弊端。随着5G网络的规模部署,可支持采用Vo NR语音解决方案来解决上述问题。This paper describes that in the initial stage of 5G network construction, the voice problem is mainly solved by epsfallback from NR network to LTE network, and the corresponding data service is also carried out in LTE network. The drop brings about the increase of call establishment delay and the disadvantage of not enjoying the high-speed Internet access of data service during the call. With the large-scale deployment of 5G networks, vonr voice solutions can be used to solve the above problems.
