摘要
为了研究LTE中上下行不平衡对VoLTE语音的影响,通过定点场景测试方式,介绍了路径损耗等指标随着小区功率参数的设置而发生的变化,分析了小区边缘极端情况下的上下行不平衡的测试数据,并经过实验证实了上下行不均衡会直接导致VoLTE用户体验变差。
In order to study the impact of uplink and downlink imbalance in LTE on VoLTE voice, the change of path loss with the configuration of the cell power parameter was introduced based on the fixed-point test mode. The tested data of the uplink and downlink imbalance on the cell edge in the extreme case was analyzed. Experiments verified that the uplink and downlink imbalance is bound to lead to the bad experience for VoLTE users.
