Abstract

There are disclosed systems and methods for performing diagnostic testing on portable communication devices, such as cellular telephones. In one embodiment, diagnostic commands are generated internal to the communication device and processed within the device as though the test commands had been received from a remote location. The processed commands can be analyzed either within the portable device or remote therefrom. For remote processing, a wireless port is provided.

Claims

1. A method for performing diagnostic testing in a portable communication device, said method comprising:

sending test signals from a source internal to said device to an output driver of said device;

redirecting said test signals back to said portable device;

processing redirected ones of said test signals within said device as though said test signals had been received at said device from an external source.

2. The method of claim 1 wherein said device is a telephone.

3. The method of claim 1 further comprising performing diagnostic testing on said processed signals.

4. The method of claim 3 wherein said diagnostic testing is performed within said portable device.

5. The method of claim 1 further comprising:

communicating said processed test signals to a remote location.

6. The method of claim 5 further comprising:

performing diagnostic testing at said remote location on communicated ones of said test signals.

7. The method of claim 1 wherein said test signals include an AT Command Set.

8. The method of claim 1 wherein said sending of said test signals to an output driver comprises transmitting an AT command request to a virtual port of said device via at least one serial driver, said at least one serial driver then processing said request from said virtual port as though said request had been received from an external source.

9. The method of claim 1 wherein said sending of said test signals comprises transmitting said signals from an internal diagnostic application to at least one serial driver, said at least one serial driver re-transmitting said signals back through said device for diagnostic processing.

10. A method for processing diagnostic information in a wireless telephone, said method comprising:

receiving at said wireless telephone a request for diagnostic information, said request having been sent by an application residing within said telephone; and

routing received requests through processing layers residing within said telephone for the purpose of diagnostic testing of said telephone, including said processing layers wherein said receiving and said routing do not involve physically coupling said wireless telephone to an external device.

11. The method of claim 10 wherein said routed requests prompt test data to be generated based on the current operational status of said telephone, including said processing layers, and wherein said method further comprises performing diagnostic testing based on generated test data.

12. The method of claim 11 wherein said diagnostic testing is performed remotely from said cellular telephone.

13. The method of claim 12 wherein said remotely performed diagnostic testing is performed by a system which performs diagnostic testing for a plurality of wireless telephones.

14. The method of claim 13 wherein said test data is wirelessly transmitted to said remote device.

15. The method of claim 14 wherein said wirelessly transmitted test data is sent over a channel other than a channel used to carry speech communications to/from said wireless telephone.

16. The method of claim 14 wherein said wirelessly transmitted test data is sent over a channel used to carry speech communication to/from said wireless telephone.

17. The method of claim 11 wherein said diagnostic testing is performed within said wireless telephone.

18. A system for providing diagnostic information for a portable communication device, said device having within it control circuitry for providing diagnostic information as a result of externally provided signals, said system comprising:

an application residing within said device operable to gather diagnostic information regarding the operation of said device, said application from time to time sending out test commands; and

means operable within said device upon receipt of said internally generated test commands for processing said test commands as though said test commands had been externally provided.

19. The system of claim 18 further comprising:

means for delivering processed ones of said test commands to a diagnostic application.

20. The system of claim 19 wherein said diagnostic application resides within said device.

21. The system of claim 18 wherein said diagnostic application resides remote from said device.

22. The system of claim 21 wherein said diagnostic application resides on a PC.

23. The system of claim 21 wherein said diagnostic application is shared in common by a plurality of said portable communication devices.

24. The system of claim 18 wherein said portable communication device comprises a cellular telephone.

25. The system of claim 18 wherein said portable communication device further comprises a wireless data network operable to transmit said processed test commands to another device.

26. A system for providing diagnostic information for a portable device, said system comprising:

means for gathering diagnostic information regarding the operation of said portable device, said means operable upon receipt of test commands from a source external to said device;

means for generating said test commands internal to said portable device; and

virtual port hardware, operable to forward internally generated ones of said test commands to said gathering means as though said test commands had originated external to said device.

27. The system of claim 26 wherein said portable device comprises a cellular telephone.

28. The system of claim 26 further comprising:

means for analyzing said gathered diagnostic information.

29. The system of claim 28 wherein said analyzing means is part of said portable device.

30. The system of claim 28 wherein said analyzing means is part of another device.

31. The system of claim 30 wherein said portable device comprises means for transmitting wireless data to said another device.

32. A system for performing diagnostic testing, said system comprising:

a wireless interface for receiving from a portable device test data which has been processed within said device; and

a processor for performing diagnostic testing on received test data from said portable device.

33. The system of claim 32 further comprising:

a transmitter for communicating the results of processed test data to said portable device.

34. The system of claim 33 wherein said communicated results are stored in said portable device.

35. The system of claim 32 wherein said wireless interface is operable for receiving test data from a plurality of said portable devices.

36. The system of claim 32 wherein said portable device is a cellular telephone.

37. The system of claim 36 wherein said wireless interface uses a TCP/IP protocol.

38. A method of performing diagnostic testing on cellular telephone sets, said method comprising the steps of:

generating a test command within said ones of telephone sets;

directing generated ones of said test commands within said telephone set such that such test commands appear to the telephone set as coming from an external source over the serial port of said telephone set;

responding to said directed test commands by sending test result data through said telephone set so that the test data is directed toward said serial port; and

redirecting said test data which is directed to said serial port to an application located within said telephone set.

39. The method of claim 38 further including the step of:

analyzing said redirected test data by said application for diagnostic testing purposes.

40. The method of claim 38 further includes the steps of:

wirelessly sending at least a portion of said redirected test data to a diagnostic testing location remote from said telephone.
