一种基于DPI的5G语音全流程分析应用方法

An application method of 5G voice whole process analysis based on DPI Technology

按照3GPP的设计,用户在5G网络使用语音业务时,需要回落到4G网络使用VoLTE语音业务进行通话。在回落的过程中,业务流程包含了多个4G、5G协同交互的信令。业务流程长,往往存在着时延过长甚至掉线的问题,这严重地影响了用户的业务体验。基于此,本文提出了一种基于DPI的5G语音全流程分析应用方法。实践显示,该方法可以大幅降低用户的5G语音接续时延,提升业务接通率,对5G用户的客户感知提升具有重要贡献。

According to 3GPP’s design,when users use voice service on 5G networks,they need to fall back to VoLTE voice service on 4G networks.In the process of rollback,the business process contains multiple 4G and 5G collaborative interaction signaling.The business process is long,and the problem of long delay or even dropped calls often exists,which seriously affects the user’s business experience.Based on this,this paper proposes an application method of 5G voice whole process analysis based on DPI.The practice shows that this method can greatly reduce the 5G voice connection delay of users,improve the service connection rate,and make an important contribution to the improvement of customer perception of 5G users.
