Abstract: 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 challenge, which is also becoming the research hotspot at present. By analyzing the framework of RRM based on BoD for broadband satellite systems, this article decomposed the framework into five main function parts. Furthermore, the exiting research achievements were corresponded to these five function parts. I}he classifying and overview on various methods for each function part were mainly discussed, and the characteristic and shortcomings for each class of arithmetic were analyzed. At last, suggestions on further research direction were proposed.
