ABSTRACT:
A system and method for testing subscriber's services and sectionalizing service trouble in distributed networks, such as Advanced Intelligent Network (AIN), includes a test call set-up component, which enables a tester to set-up a test call. A test call can be set up by the tester by interactively defining the test environment and other information to emulate a call from a subscriber's communication line. A test call can also be set-up by marking triggers in the subscriber's trigger criteria and by marking the subscriber's subscription data at the service control point/adjunct. The test call set-up component also establishes a maintenance parameter which defines the environment in which a test call is to be processed and the data to be collected, if any, during the test call. Our testing system and method also include a call history log component, which is used to collect actual data associated with the processing of a test call at each network node in the form of an actual call history log, which can be retrieved by the tester. Also, an expected call history log for each network node can be generated. The actual and expected call history logs generated at each processing node can be used by the tester to provide an end-to-end view of processing activity for the test call and to sectionalize trouble in the network.
