摘要

提出了一种基于虚拟实时服务的协议构架,可有效发掘用户提出通信请求之前的＂负时间轴＂上的空闲时频资源或可再生能源,将用户可能感兴趣的内容以多播的方式预先推送到终端的存储器中,从而以非实时的通信提供虚拟实时服务,在确保服务质量的前提下大幅度提升频谱和能量效率。对终端缓存内容的选择算法进行了标准化,从而允许基站在本地预测用户已缓存的内容,并判断当前是否应发起推送和推送哪条内容;提出了虚拟实时服务涉及的若干关键算法,也给出了虚拟实时服务的演进途径及主要开放问题,旨在为相关新兴产业的技术发展提供参考。

期刊介绍： Telecommunications Science, founded in 1956, is an information and communication technology journal sponsored by China Institute of Communications and The People's Posts and Telecommunications Press. It has been selected as a core Chinese journal and a core Chinese science and technology journal and has extensive influence in the field of information and communication because of its authority, guidance, knowledge and practicability. The targeted readers are information and communication researchers, engineering and technical personnel, middle and senior management personnel and teachers and students of information and communication universities. The magazine focuses on the achievements of major research projects (such as the National Natural Science Foundation, the National "863" Program, the National "973" Program, the National Outstanding Youth Fund, the National Education Commission's "Trans-Century Excellent Talents Training Program" Fund, the National Defense Research Fund and other projects) as well as the achievements of various innovative research topics.
