摘　　要：VoNR是运营商5G语音的目标解决方案,评估不同EVS编码下语音业务对无线覆盖的基本要求是VoNR部署和网络规划的关键问题。首先分析了VoNR无线覆盖增强技术,然后结合语音帧封装和无线传输过程,计算不同语音编码下的语音业务对无线速率要求。进一步地,以电信VoLTE打底网络800 M为例,基于链路预算对比网络承载VoLTE和VoNR能力。最后,通过多小区覆盖性能测试验证了VoNR局部试点商用的可行性。在实际部署中应优化好VoNR覆盖边缘的切换,保证语音通话的连续性。VoNR is considered by operators as a potential solution for 5 G voice,which evaluating the basic requirements for wireless coverage of voice services under different EVS codes is a key issue in VoNR deployment and network planning.Firstly,the VoNR wireless coverage enhancement technology is analyzed.Then,based on the speech frame encapsulation and wireless transmission process,the wireless rate requirements of the voice service under different speech coding are calculated.Furthermore,for the 800 M band of telecom Vo LTE network,the network carrying capability of VoLTE and VoNR are compared based on the link budget.Finally,the feasibility of local pilot commercialization of VoNR is verified through the multi-cell coverage performance test.In actual deployment,handover at the VoNR coverage edge should be well optimized to ensure the fluency of voice calls.
