中文摘要：

提出了一种延时拒绝模型下的异构无线网络接人选择算法（AS-DRM）．通过引入缓冲存储器，允许弹性业务进入缓存器队列中排队等候，当有闲置资源时按照队列中的顺序依次获得服务．利用排队论建立了异构网络接人资源占用五维马尔可夫排队模型，并分析和评价系统性能．仿真结果表明，所提算法能明显降低弹性业务阻塞率，提高系统性能．

英文摘要：

An admission selection algorithm utilizing delayed rejection model for heterogeneous wireless networks （AS-DRM） was proposed. The concept of buffer was introduced, elastic services were allowed to wait in the buffer until they could be serviced successively. Five-dimensional Markov queuing model was built by queuing theory for resource occupied in heterogeneous networks. The system performance was analyzed and evaluated. Simulation shows that this algorithm evidently decreases the blocking rate for elastic services, and the system performance is improved.
