VoLTE接续时延分析与优化实践

Analysis and Optimization of VoLTE Call Connection Delay

为降低VoLTE呼叫接续时延,提升客户感知,中国联通广东和河北分公司核心网运维人员通力协作,全面分析现网VoLTE呼叫接续时延,结合KPI分析和友商呼叫时延对比测试结果,定位影响时延的关键因素。通过系统评估现网情况,制定相应优化方案和措施,有效降低现网VoLTE接续时延。

To reduce VoLTE call connection delay and improve customer perception,China Unicom guangdong and hebei branch core network operations team work together to analyze the current network of VoLTE call connection delay comprehensively.Combined with KPI analysis and other operators’call delay test results,the key factors affecting the delay is finally located.Though evaluating the current network situation systematically,corresponding optimization schemes and measures are set out,which can effectively reduce the current network VoLTE call connection delay.
