摘　　要：为了使IMS(IP Multimedia Subsystem)离线计费系统在用户访问量增多时,能够快速的处理用户请求,提出IMS离线计费系统的自适应负载均衡算法应用框架,设计了自适应均衡负载算法,结合加权法和轮询法,根据各计费负载服务器节点的负载情况和可用的资源,进行实时均衡,用户访问量增多时系统会根据算法先将请求分配给权值高服务器节点,如果节点的权值相同系统则会根据轮询法开始进行分配,从而动态适应负载的变化,仿真实验也验证了算法的有效性。In order to process large amount of users＇ queries efficiently in IMS offline billing system, this paper designed a new application framework and presented a self - adaptive load balancing algorithm based on the new framework combined with the weighted method and polling method. According to the load and avai -lable resources of each node, the real - time balancing adjustment was carried out with the algorithm. When the amount of user in- creases, the system will prioritized the request to the server whose node weight is high. If the weights of the nod - es are the same, the system will distribute with the polling method, the change of load is dynamically adapted. Simula- tion experiments also verify the effectiveness of the proposed algorithm.
