摘　　要：无线资源管理优化是异构网络研究的重要组成部分。有限的带宽和成倍增长的网络用户,使异构无线网络的资源管理优化成为了迫切需要解决的问题。文章对接入异构网络的业务种类和异构网络资源管理进行了研究,并针对业务种类的不同提出了基于业务优先级的集中式联合无线资源管理算法。结果表明,该算法能够在保障无线资源利用率的前提下,优先使安全型业务接入网络,极大地降低安全型业务的接入阻塞率。Radio resource management optimization is an important part of heterogeneous network research. Limited bandwidth and multiplied growth of network users make resource management optimization of heterogeneous wireless networks an urgent problem to be solved. In this paper, the types of services accessing heterogeneous networks and resource management of heterogeneous networks are studied, and a centralized joint radio resource management algorithm based on service priority is proposed for different types of services. The results show that the algorithm can give priority to secure service access network under the premise of guaranteeing the utilization rate of wireless resources, and greatly reduce the access blocking rate of secure service.
