Evolution of 5G Mobile Broadband Technology and Multimedia Services Framework

摘要

Mobile video is a primary service category in 5G systems. Enhanced mobile broadband (eMBB) is oriented to the service in human user access to multimedia content. Video formats UltraHD and 3D are the most important traffic contributors to the cellular networks, thus quality of experience (QoE) requirements create new research and development opportunities. The new radio access network with multimedia broadcast eMBMS enables high-quality live video streaming as well as new audio-visual services. Standardization frameworks of ITU-R and 3GPP, minimum technical requirements and key performance indicators (KPI) are outlined in this paper. The results of recent development in MPEG network-based multimedia processing framework are also included. Technological solutions of network content caching and mobile edge computing in selected proofs of concept (PoC) are pointed out.
