摘　　要：在基于的第三代移动通信中,由于业务的多样性,使得原有的只考虑到语音业务的信道分配无法满足TD-SCDMA系统需要,在信道资源分配上需要使用动态信道分配。为了适应多业务资源管理,该文在已有的DCA研究成果基础上,对DCA各个执行阶段进行了分析和阐述,并对移动边界策略和双门限带宽预留的多业务算法做了介绍和分析,分析结果表明这些策略能更好的适应于语音和数据的业务系统。In the third generation mobile communication system,due to its multi-service ,the radio resource management schemes only to consider the voice service could not satisfy the requirements of TD-SCDMA system. In order to adopt multi-service in TD-SCDMA system,the Dynamic Channel Allocation (DCA) scheme needs to be used for assignment of the radio resource. In this paper,based on the existing DCA research results,analysis and the elaboration on each DCA stage are carried out,including the introduction and analysis on the Movable Boundary Scheme and Dual Threshold Bandwidth Reservation Scheme. The analysis result indicates that this strategy is more applicable to the voice and data operational channel.
