Design and Implementation of Load Test for 3G Online Charging System

3G oriented online charging system concept is briefly introduced at first. Then the OCS load test requirements are analyzed and the load test scenario is proposed, including the load test manners and scope, major performance benchmark data, full-service oriented traffic model and test output requirements. Based on the load test scenario, the design and implementation of OCS load tester is presented at last, which has been adapted in 3G OCS development and deployment in China telecom.
