Abstract

A system for testing a communication network component connected to a computer controlled apparatus via a data link in which the system automatically simulates telephonic communication with the communication network component. Device communication specification information is sent to a translator device at the computer controlled apparatus which automatically parses the received device communication specification to enable development of test tools for the simulation of telephonic communication between the computer controlled apparatus and the communication network component employed as a system under test. The translator in response to receipt of the device communication specification automatically generates a computer software based model to simulate a network entity, test scripts, and user documentation guide.

Claims

1. In a system for testing a communication network component connected to a computer controlled apparatus, the communication network component and the computer controlled apparatus each being connected to a data link, a method of automatically simulating telephonic communication with the communication network component comprising the steps of:

providing a device communication specification at the computer controlled apparatus;

sending the device communication specification to a translator device at the computer controlled apparatus;

automatically parsing the device communication specification to enable development of test tools for the simulation of telephonic communication between the computer controlled apparatus and the communication network component; and

automatically generating test tools for use in testing the communication network component.

2. The method of claim 1 in which the device communication specification is an abstract syntax notation one (ASN.1) specification.

3. The method of claim 2 in which the step of automatically generating test tools includes the step of automatically generating a computer software based model to simulate a network entity in response to receipt of the ASN.1 specification at the translator device.

4. The method of claim 2 including the step of automatically generating test scripts in the form of computer software based test scenarios to simulate telephonic actions.

5. The method of claim 2 including the step of automatically developing a user documentation guide in response to receipt of the ASN.1 specification at the translator device.

6. The method of claim 3 in which the simulated network entity in the form of a computer software based model is a simulation of at least one of:

(a) a telephonic network switch,

(b) a database,

(c) a wireless base station, and

(d) a telephone set.

7. The method of claim 3 including the step of automatically generating the computer software based model in C++ executable software code to simulate the behavior of the network entity.

8. The method of claim 4 in which the telephonic actions include at least one of

(a) registering a mobile telephonic unit,

(b) dialing a telephonic number, and

(c) going off-hook.

9. The method of claim 4 in which the step of automatically generating test scripts includes the step of automatically creating an event driven software program in a tool control language for establishing test scenarios.

10. The method of claim 5 in which the step of automatically developing the user documentation guide includes the step of generating the user guide in a NROFF/TROFF document format.

11. A system for testing a communication network component connected to a computer controlled apparatus, the communication network component and the computer controlled apparatus being connected to a data link comprising:

a memory device for storing a device communication specification;

a translator device at the computer controlled apparatus having an input for receipt of the device communication specification in which the translator device automatically parses the device communication specification to enable development of test tools for the simulation of telephonic communication between the computer controlled apparatus and the communication network component; and

means at the translator for automatically generating test tools for use in testing the communication network component.

12. The system of claim 11 in which the device communication specification is an abstract syntax notation one (ASN.1) specification.

13. The system of claim 12 in which the translator automatically generates a computer software based model to simulate a network entity in response to receipt of the ASN.1 specification at the translator device.

14. The system of claim 12 including means for automatically generating test scripts in the form of computer software based test scenarios to simulate telephonic actions.

15. The system of claim 12 including means for automatically developing a user documentation guide in response to receipt of the ASN.1 specification at the translator device.

16. The system of claim 13 in which the simulated network entity in the form of a computer software based model is a simulation of at least one of:

(a) a telephonic network switch,

(b) a database,

(c) a wireless base station, and

(d) a telephone set.

17. The system of claim 13 in which the translator automatically generates the computer software based model in C++ executable software code to simulate the behavior of the network entity.

18. The system of claim 14 in which the telephonic actions include at least one of:

(a) registering a mobile telephonic unit,

(b) dialing a telephonic number, and

(c) going off-hook.

19. The system of claim 14 including means for automatically creating an event driven software program in a tool control language for establishing test scenarios.
