Abstract

An automatic testing system and method are used for testing a mobile phone instead of a manual test operation. The automatic testing system uses a base station simulator and a test computer. The computer converts an operational message from the base station simulator into a test command. In the method according to the present invention, an automatic test program finds a test command corresponding to the operational message from a lookup table. The test command is then sent to the mobile phone under test and then the base station simulator validates a performance of the mobile phone by examining an execution result of the mobile phone. Test time is reduced and test correctness is enhanced for a mobile phone.

Claims

1. An automatic testing system for a mobile phone, comprising:

a base station simulator providing at least one operational message; and

a test computer connected to the base station simulator through a transmission port and converting the operational message into a test command for outputting to a mobile phone under test;

whereby the mobile phone automatically executes the test command and the base station simulator validates a performance of the mobile phone by examining an execution result of the mobile phone.

2. The automatic testing system as in claim 1, wherein the base station simulator is an Anite testing instrument from Anite Telecom Company or a CRTC testing instrument from R&

S Company.

3. The automatic testing system as in claim 1, wherein the transmission port is an RS-232 port.

4. The automatic testing system as in claim 1, wherein the computer comprises a lookup table providing a link between the operational message and the test command.

5. The automatic testing system as in claim 1, wherein the test command is an AT command.

6. The automatic testing system as in claim 1, wherein the mobile phone is connected to the transmission port for receiving the test command.

7. The automatic testing system as in claim 6, wherein the transmission port is an RS-232 port or a USB port.

8. The automatic testing system as in claim 6, further comprising a voltage converter connected between the transmission port and the mobile phone to provide a voltage level conversion between the computer and the mobile phone.

9. The automatic testing system as in claim 8, wherein the voltage converter provides signal transmission between the computer and the mobile phone by connecting associated pins of the computer and the mobile phone.

10. The automatic testing system as in claim 1, further comprising a power supply connected between the computer and the mobile phone for supplying power to the mobile phone.

11. The automatic testing system as in claim 10, wherein the power supply is connected to the computer through a GPIB interface.

12. An automatic testing method for a mobile phone, comprising the steps of:

providing a test computer to test a mobile phone under test;

the test computer converting an operational message from a base station simulator into a test command;

the test computer sending the test command to the mobile phone; and

the base station simulator validating an execution result of the mobile phone.

13. The automatic testing method as in claim 12, wherein the test computer converts the operational message from the base station simulator into the test command according to a lookup table and the lookup table provides a link between the operational message and the test command.

14. The automatic testing method as in claim 12, wherein the test command includes a data transmission command and a power control command.

15. The automatic testing method as in claim 12, wherein the test command is an AT command.

16. The automatic testing method as in claim 12, wherein the base station simulator is an Anite testing instrument from Anite Telecom Company or a CRTC testing instrument from R&

S Company.

17. The automatic testing method as in claim 12, further comprising the step of:

providing a voltage converter to provide a voltage level conversion between the computer and the mobile phone.

18. The automatic testing method as in claim 12, further comprising the step of:

the computer controlling a power supply to supply power to the mobile phone.

19. The automatic testing method as in claim 18, wherein the power supply is connected to the computer through a GPIB interface.

20. The automatic testing method as in claim 12, further comprising the step of:

the computer receiving a response message from the mobile phone.

21. The automatic testing method as in claim 20, further comprising the step of:

the computer displaying an execution result according to the response message.

22. The automatic testing method as in claim 12, wherein the base station simulator validates an execution result of the mobile phone by receiving and examining a wireless signal from the mobile phone.
