摘　　要：无线资源管理技术是宽带多媒体卫星通信研究的一个重要内容。如何有效应对多媒体业务的突发性问题,以获得业务QoS与资源利用率之间的较好平衡,是无线资源管理技术面临的主要挑战。基于带宽按需分配的卫星无线资源管理机制是一个有效的解决途径与发展方向,也是目前研究的热点。在分析基于带宽按需分配的卫星无线资源管理体系结构的基础上,将其分解为5个主要功能部分,并将现有宽带卫星无线资源管理技术的研究成果分别对应到这5个功能,重点对每个功能近年来的实现算法进行了分类总结,并分析比较了各类算法的特点与存在的问题,最后就进一步的研究方向提出了建议。Radio Resource Management （RRM） is an important researching aspect in broadband multimedia satellite communication. Dealing effectively with burst characteristic of multimedia to achieve balance between QoS of traffics and resource utility is the main challenge for RRM. The RRM based on bandwidth is an effective approach for this chal- lenge, which is also becoming the research hotspot at present. By analyzing the framework of RRM based on PoD for broadband satellite systems, this article decomposed the framework into five main function parts. Furthermore, the exi- ting research achievements were corresponded to these five function parts. The classifying and overview on various methods for each function part were mainly discussed, and the characteristic and shortcomings for each class of arithme- tic were analyzed. At last, suggestions on further research direction were proposed.
