摘　　要：针对下一代网络中多媒体业务的接入要求和对媒体服务器资源控制的要求,提出一种新型的支持客户预约的媒体服务器资源分配算法.采用按时间段进行资源判断处理的方法,将总时间划分为媒体服务器资源未用、已用完和部分未用3个时间片集合,找出客户申请时间段所属集合,针对时间段内资源的使用状况,交互式地为用户进行资源预留.仿真结果表明,在支持客户预约的情况下,本算法提高了业务成功接入率和媒体服务器资源有效使用率.According to the connecting requirement of multimedia service and the control requirement of media-server resource in next generation networks, a new allocation algorithm is proposed; it supports customer reservation in the new algorithm, a method that manages media-server resource in terms of the time slice is adopted. Total time slice is divided into three sets of time slice, including the unused, the exhausted and the partially used. After judging what set the user＇ s requests belong to, the status of resource in these time slices is analyzed, and then reserved interactively. This algorithm can improve the hit rate of multimedia service as well as the availability of media-server resource.
