Abstract

A network operations center comprised of hardware and software that tests paging devices, such as two-way paging devices to determine that they conform to a specified protocol.

Claims

1. A system providing a multi-channel wireless communications testing environment, said system comprising:

a transmitter;

a receiver; and

a protocol engine interfaced to the transmitter and receiver to send and receive information to and from a two-way communication device, respectively, to test the two-way communication device for compliance with a plurality of communication protocols, wherein the protocol engine transmits and receives information over multiple channels simultaneously.

2. The system defined in claim 1 wherein the protocol engine performs scheduling for a selected protocol.

3. The system defined in claim 1 wherein the communication device comprises a paging device.

4. The system defined in claim 1 wherein the protocol engine is operable to send and receive information to perform engineering testing, manufacturing testing and application testing.

5. The system defined in claim 1 wherein the plurality of protocols comprises at least a one-way communication protocol and at least a two-way communication protocol.

6. The system defined in claim 1 wherein the protocol engine uses scripted tests when testing the communications device.

7. The system defined in claim 6 further comprising an automated test script storage area to store and permit access to a scripted set of tests.

8. The system defined in claim 1 further comprising a device driver to transfer information between the protocol engine and both the receiver and the transmitter.

9. The system defined in claim 1 wherein the protocol engine comprises a series of instructions executed on at least one processor.

10. A system providing a multi-channel wireless communications testing environment, said system comprising:

transmitter and receiver hardware to transmit and receive information to and from communications devices using a plurality of channels; and

a protocol engine interfaced to the transmitter and receiver hardware via a device driver to send and receive information to and from the communication devices, respectively, to test the communication devices for compliance with a plurality of communication protocols over the plurality of channels simultaneously.

11. The system defined in claim 10 further comprising a user interface to enter information to control the protocol engine.

12. The system defined in claim 11 wherein the user interface permits a user to select one of the plurality of communication protocols for testing.

13. The system defined in claim 10 further comprising an automated test storage area storing at least one scripted test.

14. The system defined in claim 13 wherein said at least one scripted test comprises an ASCII coded text file.

15. The system defined in claim 13 wherein said at least one scripted test comprises information for configuring the system and sending messages through the system.

16. The system defined in claim 10 wherein the protocol engine comprises a retry message layer to facilitate resending of a previously sent message when an acknowledgment confirming successful transfer of the previously sent message has not been received.

17. The system defined in claim 10 wherein the protocol engine performs scheduling and transmitting for each of the plurality of protocols.

18. The system defined in claim 10 wherein the protocol engine uses an object-oriented structure.

19. The system defined in claim 10 wherein the protocol engine accesses a database to obtain device specific information to facilitate testing of a communication device.

20. The system defined in claim 19 wherein the device specific information comprises information to facilitate retrying to send a message to the communication device during a test.

21. The system defined in claim 19 wherein the device specific information comprises information to facilitate scheduling transmissions to and from the communication device during a test.
