IMS数据通道技术研究

Research on IMS Data Channeltechnology

5GVoNR+极大拓展了传统实时音视频通信的内涵,作为关键技术之一的IMS数据通道技术在不断走向成熟,3GPP、GSMA等标准组织以及国内各大运营商和设备制造商一直在对IMS数据通道技术开展研究。基于在5G新通信研究过程中对IMS数据通道技术的探究,介绍IMS DC技术的发展历程,当前版本下的架构及其涉及的新增网元功能,并提出了一些需要继续讨论和完善的问题。

5G VoNR+has greatly expanded the connotation of traditional real-time audio and video communication,and IMS data channel technology,as one of the key technologies,is constantly maturing.3GPP,GSMA as well as Chinese operators and equipment manufacturers have been conducting research on IMS data channel technology.This paper introduces the development ofIMS data channel technology,the current architecture and the new NE functions involved,and puts forward some problems that need to be further discussed and improved.
