Analysis And Implementation Of VoLTE Project

The LTE network is developing rapidly in the world,and the LTE voice solution is also a key issue for the industry in the development of LTE networks and terminals.Because the LTE network is based entirely on the unified packet domain architecture and cannot provide circuit domain-based voice calls like 2G/3G,implementing voice solutions for VoLTE across the entire network is an inevitable trend for LTE voice development.Therefore,this article specifically introduces VoLTE voice solutions,including VoLTE technology networking solutions,call flow,and technical features.On the one hand,VoLTE technology can significantly improve wireless spectrum utilization and reduce network costs.Because for voice services,spectrum utilization efficiency of LTE is much better than that of traditional systems,which is more than4 times that of GSM.On the other hand,the user experience is improved,and the experience of VoLTE is obviously better than that of traditional CS voice.First,the introduction of high-definition voice and video codecs significantly improves the quality of communications,secondly,the call duration of VoLTE is significantly shortened.Tests show that VoLTE shortens more than half of CS calls.Third,seamless integration with RCS can bring richness.These are not available in traditional speech.This article starts with the TD-LTE network dominated by China Mobile,and first compares the various LTE voice solutions.It elaborates on the network function modules,mobility management processes,and signaling flow of the VoLTE network,secondly,it discusses the current status of mobile networks in Inner Mongolia.Introduce and propose the VoLTE transformation plan for Inner Mongolia Mobile Core Network and conduct deployment test.Finally,two solutions to the important aspects of VoLTE's end-to-end technical process are proposed.At the same time,it combines the specific cases generated in the daily actual optimization process,sums up and summarizes,targeted analysis and resolution,and effectively improves VoLTE's quality indicators and user's call perception,providing sufficient theoretical and practical foundations for future work.
