Abstract

A method and system for testing subscriber identity module application toolkit (SAT) functionality. The method of the present invention includes loading a first computer program into a SIM card and loading a second computer program comprising a software tool for designing test, measurement, and control systems into a computer. The second computer program is executed to trigger an event which causes the first computer program to send a proactive command. The proactive command data is then sent to the SIM card through a terminal response command.

Claims

1. A method of testing subscriber identity module application toolkit (SAT) functionality, comprising the steps of:

loading a first computer program into a SIM card;

loading a second computer program comprising a software tool for designing test, measurement, and control systems into a computer;

executing the second computer program to trigger an event which causes the first computer program to send a proactive command; and

sending the proactive command data to the SIM card through a terminal response command.

2. The method of claim 1, further comprising using a SIM card menu that is adapted to execute a hard coded proactive command.

3. The method of claim 2, wherein the hard coded proactive command is a command for receiving data.

4. The method of claim 1, further comprising the steps of:

using a method in a SIM card menu to build new proactive commands; and

sending by the SIM card the new proactive commands when the proactive command data are passed to the SIM card.

5. The method of claim 4, further comprising the step of sending the data for the proactive command first to target test code (TTC) through a method of the second computer program.

6. The method of claim 5, further comprising the step of using the TTC to execute at least one open platform API (OPA) function.

7. The method of claim 6, wherein the TTC is written in the C programming language.

8. The method of claim 1, wherein the first computer program is written in the JAVA programming language.

9. The method of claim 1, wherein the second computer program is written in the testing program LabView.

10. A method of testing the functionality of a subscriber identity module (SIM card) application toolkit (SAT), comprising the steps of:

calling by software executed on a computer a proactive command interface on an open platform application programming interface (OPA) using a target test code (TTC);

calling by the software executed on the computer the SAT functionality in the software backplane (SwBP);

executing by a SIM card a menu containing the hard coded proactive command;

executing by a mobile terminal the proactive command sent from the SIM card; and

responding by the mobile terminal with a terminal response to the SIM card.

11. The method of claim 10, further comprising the step of adding the proactive command parameters to the terminal response before the mobile terminal responds.

12. A method of testing SAT functionality using a PC running a test program, a mobile terminal having a target test code (TTC) and a SIM card having loaded thereon an applet, comprising the steps of:

planning a test case;

designing the test case;

implementing the test case;

validating the test case;

executing the test case; and

analyzing the results of the test case.

13. The method of claim 12, wherein the validating step is designed to confirm that the test program on the PC, the applet on the SIM card and test case parameters are valid.

14. The method of claim 13, wherein the test program on the PC is LabView and the executing of the test case step is undertaken by running a LabView script.

15. The method of claim 14 wherein the LabView script executes the test case and the test case procedure is performed automatically.

16. The method of claim 15, wherein the result from the test case is a terminal response that is compared to a reference value.

17. The method of claim 16, wherein the result of the test is displayed in a LabView front panel.

18. A method for testing subscriber identity module (SIM) application toolkit (SAT) functionality, comprising the steps of:

loading a Java applet adapted for building proactive commands on a SIM card;

loading a LabView test program on a PC adapted to generate parameters for building a proactive command;

implementing a target test code (TTC) of a mobile terminal;

executing a LabView script with a test case adapted to send the proactive command;

writing a configuration data file so as to support the LabView script with test cases data needed for the generation of proactive command; and

writing a reference file such that results data from test case execution are compared to a reference file data.

19. The method of claim 18, further comprising the step of using a card reader/writer device to load the Java applet on the SIM card.

20. A method for testing functionality of a subscriber identity module (SIM) application toolkit (SAT), comprising:

communicating, by a personal computer (PC) with a mobile terminal using a LabView script via target test code (TTC) of a mobile terminal;

capturing, by the LabView script, a terminal response that is sent to the SIM card; and

comparing the terminal response with the correct terminal response defined in 3GPP specification.

21. The method of claim 20, further comprising the step of creating test cases.

22. The method of claim 21, further comprising the steps of:

preparing the test case;

executing the test case; and

cleaning up the test case.

23. The method of claim 22, wherein preparing the test case further comprises the step of initializing the mobile terminal and determining the test case parameters.

24. An arrangement for testing the functionality of a subscriber identity module (SIM) application toolkit (SAT), comprising:

an applet loaded on a SIM card;

a target test code (TTC) module loaded on a mobile terminal;

a testing program module loaded on a PC;

wherein an automated script of the testing program on the PC is adapted to send parameters, for building proactive commands, to the TTC of the mobile terminal and wherein the TTC of the mobile terminal is adapted to send a terminal response, as a result of the proactive command, to the SIM card applet.

25. The arrangement of claim 24, wherein the Java applet of the SIM card is adapted to return a terminal response to the testing program of the PC via the TTC of the mobile terminal.

26. The arrangement of claim 25, wherein the testing program is adapted to automatically compare the proactive command and the terminal response with a reference file.

27. The arrangement of claim 26, adapted to send proactive commands defined in 3GPP for testing SAT.

28. The arrangement of claim 24, further comprising a means of triggering SAT application on the SIM card through a script written in LabView.

29. The arrangement of claim 24, wherein the Java applications are downloaded to the SIM card using a card reader/writer device.

30. The arrangement of claim 29, wherein the SIM card is inserted in a mobile terminal before performing the test.
