摘　　要：分析了全业务的组合话务量、用户信用状态分布以及业务时长/流量模型,给出了diameter credit control(DCC)协议压力计算方法,提出了与被测系统反应无关和有关的2种模拟压力生产控制模型以适应不同的压力测试内容.该压力测试模型在中国电信面向3G的在线计费系统建设中得到成功应用,并可有效支持高性能的DCC协议压力测试.3G oriented online charging system （OCS） concept is briefly introduced at first. Then the major diameter credit control （DCC） protocol performance benchmark data to be handled by OCS is described. The composed full-services traffic, user credit status, service duration/traffic distribution are analyzed and the calculation formula for DCC protocol load is presented. The two load control mod- els including tested system unresponsive and responsive model are proposed for different load test cases. The integrated load test model was adapted in 3G OCS development in China Telecom, and the test results show the model can support high performance load test for DCC protocol.
