5G VoNR+之IMS Data Channel概念
2022-07-06 22:15:00 【LinkEverything】
VoNR,即Voice over New Radio,是VoLTE(Voice over LTE)的演进版本。相比于VoLTE,VoNR除了空口变成了NR之外,其他IMS相关的基本架构和流程与VoLTE并无大的变化。
VoNR可以提供语音通话、视频通话以及彩铃、彩振等增值业务。所谓的VoNR+,是希望在此之外,提供图片、文字、网页、位置等更丰富的新业务。
在VoNR业务中,空口承载有三条,IMS信令承载、IMS voice承载和IMS video承载。而为了支撑VoNR+所增加的业务需求,新增了一条承载,称为IMS DC(即Data Chennel)。下图是中国移动白皮书中的IMS DC示意图。

基于VoNR+ IMS DC的典型应用场景是智能客服,相比于传统的通过按键沟通方式,增加了交互式菜单,结合语音和菜单的交互,对用户体验和服务效率能有很大提升。
在3GPP TS 26.114中,对MTSI业务(Multimedia Telephony Service for IMS)的架构做了定义。

其中,跟用户交互的部分包括,键盘、摄像头、麦克风、显示屏、喇叭。它们所产生和交互的内容包括文本、音频、视频、还有网页等媒体内容。在这个架构图中,Packet-based network interface就是空口的承载,也就是前面所说的IMS信令承载、IMS语音承载、IMS video承载、Data channel。
