摘要
5G网络具有超高速率、超低时延、高可靠性等显著优势,为广播电视提供了更好的内容传输质量。首先,分析5G网络的技术特点及关键技术框架,包括无线传输、终端直通(Device-to-Device,D2D)通信等,为广播电视网络融合的建设奠定了基础。其次,对比分析广播电视的有线、无线、互联网3种传输方式,并提出它们与5G网络的整合,实现传输的高效化和智能化。最后,提出5G移动与广播电视网络融合的总体框架,包括基础设施层、网络功能层、内容分发层等,并分析相应的核心技术。
5G networks have significant advantages such as ultra-high speed,ultra-low delay,and high reliability,providing better content transmission quality for radio and television.First of all,the technical characteristics and key technical framework of 5G network are analyzed,including wireless transmission,Device-to-Device(D2D)communication,etc.,which lays the foundation for the construction of radio and television network integration.Secondly,it compares and analyzes three transmission modes of radio and television,namely wired,wireless and Internet,and puts ofrward their integration with 5G network to achieve high efficeincy and intelligence of transmission.Finally,the overall framework of 5G mobile and broadcast TV network integration is proposed,including infrastructure layer,network function layer,content distribution layer,and the corresponding core technologies are analyzed.
