摘　　要：In this paper, a novel admission scheme is proposed which provides high degrees of quality of service (QoS) guarantees for multimedia traffic carried in mobile networks. The proposed scheme combines the admission control and bandwidth reservation to guarantee QoS requirements. It considers both local information and remote information to determine whether to accept or reject a connection. In order to embody the characteristics of the algorithms proposed in the article, two traditional algorithms of admission control are used for comparison. In the end of the paper the simulation analyses are given and the results show that the proposed algorithm can adjust the bandwidth according to the current status of networks and decrease the probability of connections forcibly dropped. The most important thing is that the algorithm is based on the multimedia communications and can guarantee the QoS of real time connections through decreasing the bandwidth of non real time connections.提出了一种能在承载多媒体业务的移动通信网络中提供较高服务质量保证的接入控制方法 .该方法将接入控制与带宽预留相结合 ,保证传输业务服务质量的要求 .仿真结果表明 ,与两种传统的接入控制算法相比 ,本文所提出的算法能够使强行中止概率降低 .
