【摘要】：移动数据分流(Mobile Data Offloading)是近年来一个比较新的研究热点。为了解决用户日益增长的移动数据需求给蜂窝网络运营商造成的流量负载和网络拥塞等问题,移动数据分流被提出来,即将蜂窝网络的数据分流到无处不在的用户间本地机会通信。其基本思想是通过蜂窝网络分发数据对象到一部分订阅用户(称为种子用户),再由种子用户通过本地机会通信(如Bluetooth、WiFi Direct、DSRC、Device-to-Device in LTE等)或基于WiFi AP辅助的方式传送给其他订阅的用户。首先从总体上概述了当前对数据分流研究的背景、意义和具体的研究进展。然后针对当前国内外学术界对这方面的研究内容和趋势,按照形式和技术路线对数据分流的方案进行了归类,并对各种类型的分流方案进行了综述。最后结合现实环境进行总结。
[Abstract]:Mobile data offloading is a new research hotspot in recent years. In order to solve the problems of traffic load and network congestion caused by the increasing demand of mobile data for cellular network operators, mobile data streaming has been put forward. The data of cellular network will be diverted to local opportunity communication between ubiquitous users. The basic idea is to distribute data objects to some subscribers (called seed users) via cellular networks, and then send them to other subscribers via local opportunity communication (such as Bluetooth / WiFi DirectCor Device-to-device in LTE) or WiFi AP assisted mode. Firstly, the background, significance and progress of current research on data diversion are summarized. Then, according to the current research content and trend of domestic and foreign academic circles, this paper classifies the scheme of data diversion according to the form and technical route, and summarizes the various kinds of diversion schemes. Finally, combined with the reality of the environment to sum up.
