摘　　要：端到端重配置技术起源于软件无线电,软件无线电技术实现了终端的多模式支持功能,并实现了软件从空中接口的下载。端到端重配置技术利用软件无线电提供的重配置能力,构建起以可重配置的终端、基站等网元为主体的体系结构,结合先进的动态网络规划、灵活频谱管理和联合无线资源管理技术,实现对重配置能力和异构无线资源的有效利用,保证用户的无缝业务体验。本文论述了端到端重配置技术的产生背景、基本概念和研究现状,对重配置研究中的主要问题和关键技术(包括架构、规划和管理等方面的内容)进行了系统的总结,最后就重配置未来研究的重点提出了自己的看法。Software defined radio is the basis for end-to-end reconfignration technology. SDR realized to implement multi-mode terminal and software download from the radio interface, while reconfiguration aims at bringing full benefit of reconfigurability to the heterogeneous radio environment in the aspect of resource management and service provisioning, by establishing the system architecture based on reconfigurable terminal and other network elements. Dynamic network planning and flexible management, flexible spectrum management and joint radio resource management are the key enabling technologies in reconfiguration research area. The paper first gives the background introduction of end-to-end reconfiguration, including, the concept and the research situation. Then focus on several important problems and enabling technologies. Finally, we end this paper with some advice on the future research point of reconfiguration.
