Abstract

Method and apparatus for testing in a communication network is described. One example of the invention relates to a method of testing in a voice over internet protocol (VOIP) network. At least one test script is obtained from the VOIP network at an enhanced terminal adapter. The enhanced terminal adapter is configured to couple at least one communication device to the VOIP network. The at least one test script is executed within a scripting framework of the enhanced terminal adapter to interact with at least one component coupled to the VOIP network. Results of the execution of the at least one test script are transmitted from the enhanced terminal adapter to the VOIP network.

Claims

1. A method of testing in a voice over internet protocol (VOIP) network, comprising:

collecting call statistics at an enhanced VOIP terminal adapter during execution of standard call flows, the enhanced VOIP terminal adapter being configured to couple at least one communication device to the VOIP network, receive and place calls, and obtain configuration profiles from a provisioning server;

analyzing the call statistics to identify call quality problems;

obtaining at least one test script from the VOIP network at the enhanced VOIP terminal adapter based on the identified call quality problems;

executing the at least one test script within a scripting framework of the enhanced VOIP terminal adapter to interact with at least one component coupled to the VOIP network; and

transmitting results of the execution of the at least one test script from the enhanced VOIP terminal adapter to the VOIP network.

2. The method of claim 1, further comprising:

obtaining a configuration profile at the enhanced VOIP terminal adapter from the VOIP network, the configuration profile including information identifying the at least one test script and a test script server from which the at least one test script can be obtained.

3. The method of claim 1, further comprising:

obtaining an execution sequence for the at least one test script at the enhanced VOIP terminal adapter from the VOIP network;

where the at least one test script is executed based on the execution sequence.

4. The method of claim 1, wherein the step of executing the at least one test script comprises at least one of:

making a VOIP call from the enhanced VOIP terminal adapter to the at least one component;

receiving a VOIP call from the at least one component at the enhanced terminal adapter;

or

attempting communication between the enhanced VOIP terminal adapter and the at least one component.

5. The method of claim 1, wherein each of the at least one test script is independent of an operating system of the enhanced terminal adapter.

6. The method of claim 5, wherein the step of executing the at least one test script comprises:

calling at least one function of an application programming interface (API) from the scripting framework, the API exposing native functions of the operating system, at least one module in the enhanced terminal adapter, or both the operating system and the at least one module; and

receiving at least one event at the scripting framework from the operating system, the at least one module, or both the operating system and the at least one module using callback wrappers defined by the API.

7. The method of claim 1, wherein the act of analyzing the call statistics to identify call quality problems further includes computing call quality metrics based on the analyzed call statistics;

and identifying a call quality problem based on the call quality metrics.

8. An enhanced voice over internet protocol (VOIP) terminal adapter for coupling at least one communication device to a voice over internet protocol (VOIP) network, comprising:

terminal adapter and routing logic configured to make and receive VOIP calls;

a test script manager configured to obtain at least one test script from the VOIP network based on one or more identified call quality problems during execution of standard call flows executed by the terminal adapter; and

a scripting framework module configured to execute the at least one test script to interact with at least one component coupled to the VOIP network and transmit results of the execution of the at least one test script to the VOIP network.

9. The enhanced VOIP terminal adapter of claim 8, further comprising:

provisioning logic configured to obtain a configuration profile from the VOIP network, the configuration profile including information identifying the at least one test script and a test script server from which the at least one test script can be obtained.

10. The enhanced VOIP terminal adapter of claim 8, wherein the test script manager is configured to obtain an execution sequence for the at least one test script from the VOIP network, and wherein the scripting framework module is configured to execute the at least one test script based on the execution sequence.

11. The enhanced VOIP terminal adapter of claim 8, wherein the scripting framework module is configured to at least one of:

make a VOIP call to the at least one component;

receive a VOIP call from the at least one component;

or

attempt communication with the at least one component.

12. The enhanced VOIP terminal adapter of claim 8, further comprising:

a processor; and

a memory having an operating system executed by the processor;

wherein each of the at least one test script is independent of the operating system.

13. The enhanced VOIP terminal adapter of claim 12, further comprising:

at least one module; and

an adaptation layer having an application programming interface (API), the API exposing native functions of the operating system, the at least one module, or both the operating system and the at least one module, the API defining callback wrappers for receiving events from the operating system, the at least one module, or both the operating system and the at least one module;

wherein the scripting framework is configured to call at least one function of the API and receive at least one event using the callback wrappers.

14. The enhanced VOIP terminal adapter of claim 8, further comprising:

statistic capture logic configured to collect call statistics during execution of standard call flows by the terminal adapter and routing module, and send the call statistics to the VOIP network.

15. Apparatus for testing in a voice over internet protocol (VOIP) network, comprising:

a) at least one processor; and

b) at least one storage device storing processor-executable instructions which, when executed by the at least one processor, perform a method including

collecting call statistics at an enhanced VOIP terminal adapter during execution of standard call flows, the enhanced VOIP terminal adapter being configured to couple at least one communication device to the VOIP network, receive and place calls, and obtain configuration profiles from a provisioning server;

analyzing the call statistics to identify call quality problems;

obtaining at least one test script from the VOIP network at the enhanced terminal adapter based on one or more identified call quality problems during execution of standard call flows executed by the terminal adapter;

executing the at least one test script within a scripting framework of the enhanced VOIP terminal adapter to interact with at least one component coupled to the VOIP network; and

transmitting results of the execution of the at least one test script from the enhanced VOIP terminal adapter to the VOIP network.

16. The apparatus of claim 15, wherein the method further includes obtaining a configuration profile at the enhanced VOIP terminal adapter from the VOIP network, the configuration profile including information identifying the at least one test script and a test script server from which the at least one test script can be obtained.

17. The apparatus of claim 15, wherein the method further includes obtaining an execution sequence for the at least one test script at the enhanced VOIP terminal adapter from the VOIP network;

and

where the at least one test script is executed based on the execution sequence.
