摘要:

5G XR(extended reality,扩展现实)及多媒体增强是5G-Advanced网络中非常重要的业务场景,随着用户对新兴的新媒体服务的需求逐渐增长,网络需要针对 XR 等多媒体业务做出相应的增强。主要介绍了XR及增强多媒体的主要业务场景,包括沉浸式虚拟现实、增强现实、基于混合现实的远程遥控技术、虚拟工厂、远程无人机控制等。针对XR的典型业务场景,在已有的国际标准对XR技术的研究和支持的基础上,针对5G XR及多媒体增强,仍然需要在QoS机制设计、网络和应用的相互感知和传输协同、大规模XR业务流的同步传输以及节能等方面进行针对性设计,从而实现5G网络对XR及多媒体增强业务更好的支持。

关键词: XR, 多媒体增强, 多流协同, 5G架构增强

Abstract:

5G XR and enhancement on media service are very important business scenarios in 5G-Advanced network.With the increasing user demands for emerging new media services, 5G network needs to make corresponding enhancements for media services such as XR.The main business scenarios of XR and augmented multimedia were mainly introduced, including immersive virtual reality, augmented reality, remote control technology based on mixed reality, virtual factory, remote unmanned aerial vehicle control, etc.For the typical business scenarios of XR, there were already some specifications and on-going studies in 3GPP.Based on these existing activities, 5G network need further enhancements including 5G QoS framework for XR service, coordination between network and application, synchronization of flows of multi-user and multi-stream, power saving of terminals and network etc., so that the 5G network could provide better support to 5G XR and enhanced media services leveraging the above enablers.

Key words: XR, enhancement on media service, coordinated dataflow, enhancement on 5G architecture
