摘要
对900 MHz LTE的VoLTE性能进行了分析。首先结合理论和测试结果分析900 MHz频段的能力,并总结了VoLTE语音评价方法。其次通过试验结果分析在深度覆盖场景下L900 VoLTE业务的性能,同时与L1800 VoLTE,U2100语音作对比。最后根据大量的试验数据拟合3G的RSCP-MOS曲线和4G的RSRPMOS曲线,为L900的VoLTE部署提供参考。
The performance of VoLTE on 900 MHz band for LTE network is analyzed.Firstly,the capacity of 900 MHz band is analyzed,and the method of VoLTE voice evaluation is summarized.Secondly,According to the test result,compared with the L1800 VoLTE and U2100 voice,VoLTE service in the depth coverage scenes is analyzed.Finally,according to a large number of experimental data,3G RSCP-MOS curve and 4G RSRP-MOS curves are fitted,which could provide a reference for deploying VoLTE in 900 MHz band.
