摘　　要：伴随"互联网+"概念的提出以及快要到来的5G时代,用户通信互联的需求不断上升,一种新型的接入网架构——云无线接入网(C-RAN)应运而生。通过在C-RAN中使用网络频谱分配策略,用户的QoS需求可以得到有效改善。利用云无线接入网可以进行集中化处理的优势,建立了QoS用户需求模型。同时运用该模型,结合启发式搜索蚂蚁算法,提出了基于QoS的频谱资源分配策略。通过仿真结果显示,相比与其他分配算法,该策略能够有效提升网络频谱利用率,满足用户QoS需求。With the advance of ＂Internet ＋＂ and the coming of the 5 G era, the communication requirements of network users is growing, a new network frame--cloud radio access network（C-RAN） came into being. The user＇s QoS requirements can be effectively improved by optimizing the network spectrum allocation strategy in the C-RAN. Based on the advantages of centralized processing in the C-RAN, the QoS user＇s requirement model is set up. At the same time, based on this model, combined with heuristic search ant algorithm, a network resource allocation strategy based on QoS is proposed. The simulation results show that compared with other allocation algorithms, this strategy can effectively improve the network spectrum utilization and meet the user＇s QoS requirements.
