摘　　要：正确评估VoLTE业务的服务质量对于LTE网络运营商至关重要,因此通过调研语音QoS和VoLTE的相关标准,明确VoLTE端到端QoS指标及其目标值,最后给出了利用现有技术测试VoLTE端到端QoS的方法。Voice over LTE is a solution to transfering voice packets over the LTE network with low latency and high Quality of Service. The accurate assessment of QoS of VoLTE service is of importance to operators of the LTE network. The relaled standards of voice QoS and VoLTE were investigated to determine the end-to-end QoS indicators and target values for VoLTE. Finally, the method to test end-to-end QoS for VoLTE using existing technology was presented.
