Abstract

A system software solution for testing various network elements/entities and processes in a telecommunications network is provided. A network under test contains network entities which save data to a common database that is associated with processing particular test cases. A server correlates database data from the network under test and compares it to anticipated test case results. A disposition of the test cases is determined. Various elements of the invention interface appropriately, and process accordingly, to accomplish the testing and test result(s) disposition. In addition, the test system provides a means to verify billing records within the telecommunications network. Integrated into the system is logic that captures timepoints associated with critical events in a phone call from a test application perspective (particularly the events important to correct billing) and comparing those timepoints with actual results from the tested network. Timepoints are time information with milestones in the progress of call processing. Time information of applicable network elements is first assured to be synchronized, or translated for consistency. The test application timepoints are gathered, compared to billing records associated with the test case (e.g. call), and used to produce an accurate test case result.

Claims

1. A method for testing a telecommunications network including a network information concentrator and a trunk group filter table coupled with said network, said method comprising the steps of:

retrieving an entry from the network information concentrator'"'"'s queue;

parsing the entry from the network information concentrator'"'"'s queue to identify a call record;

synchronizing the entry utilizing timepoint information in the call record, wherein the timepoint information correlates the call record with a common time reference;

comparing entries in the trunk group filter table to the call record;

discarding the call record if the trunk group filter table entry indicates the call record is not of interest; and

inserting the call record into a database if the trunk group filter table entry indicates the call record is of interest for testing the telecommunication network.

2. The method as recited in claim 1, including the steps of:

(a) retrieving call records from the database by matching a particular test case number;

(b) formatting a test script based on the test case number and information stored in the database; and

(c) executing the test script against the call records from the database to test the telecommunication network.

3. The method as recited in claim 2, including the step of handling any errors in the call records.

4. The method as recited in claim 2, including the step of logging test results in the database.

5. The method as recited in claim 2, including the step of certifying the test results.

6. The method as recited in claim 2, including the steps of:

(a) retrieving a test case number, start time, end time, and timepoint information from the database;

(b) retrieving call records that match the retrieved test case number and start time;

(c) testing the telecommunication network utilizing the returned call records; and

(d) determining appropriate corrective action utilizing test results and the database.

7. The method as recited in claim 2, including the step of logging an error in the database if no matching call records are identified.

8. A system for testing a telecommunications network including a network information concentrator and a trunk group filter table coupled with said network, said system comprising:

(a) a database that stores call information;

(b) logic that retrieves stored call information from the database and parses the information into one or more call record,

(c) logic that synchronizes the entry utilizing timepoint information in the call records wherein the timepoint information correlates the call record with a common time reference;

(d) logic that compares entries in the trunk group filter table to the one or more call records and discards any call record if the trunk group filter table entry indicates the call record;

is not of interest; and

(e) a database for storing the call record if the trunk group filter table entry indicates the call record is of interest for testing the telecommunication network.

9. The system as recited in claim 8, including:

(d) logic that retrieves call records from the database by matching a particular test case number;

(e) logic that formats a test script based on the test case number and information stored in the database; and

(f) logic that executes the test script against the call records from the database to test the telecommunication network.

10. The system as recited in claim 9, including logic that handles any errors in the call records.

11. The system as recited in claim 9, including logic that logs test results in the database.

12. The system as recited in claim 9, including logic that certifies the test results.

13. The system as recited in claim 9, including:

(a) logic that retrieves a test case number, start time, end time, and timepoint information from the database;

(b) logic that retrieves call records that match the retrieved test case number and start time;

(c) logic that tests the telecommunication network utilizing the returned call records; and

(d) logic that determines appropriate corrective action utilizing test results and the database.

14. The system as recited in claim 9, including logic that logs an error in the database if no matching call records are identified.
