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。

Abstract

A virtual rea1-time service infrastructure for future wireless access，which is capable of efficiently using the idle timeslots or renewable energy distributed in the“negative time-axis”before users’ transmission requests was proposed. By using these idle timeslots，the information content in which users might be interested can be pushed to the end devices’ buffers in a multicasting manner before a user requests the content. The end devices’ algorithm which determines which content should be buffered was standardized. Hence，the base-station may locally predict what have been buffered in the users’ devices，and determine whether it should push and which content to transmit. Meanwhile，a number of key algorithms for virtual rea1-time service were proposed and analyzed，an evolution path toward virtual rea1-time service along with its major problems was also presented. Chen’s program was proposed to guide the development of the virtual rea1-time service related emerging industry and technologies.
