Abstract

Apparatus and accompanying methods for use therein for implementing a method and system for emulating a supporting mobile for testing a packet-data communication device. Thus, the present invention is directed to, in a general aspect, a system, and accompanying methods for use therein, for packet data communications. In a preferred embodiment the invention relates to testing of packet data applications including wireless communications such as push to talk over cellular (PoC) wireless telecommunications applications. The test system of the present invention comprises an emulated communication device for transmitting and receiving packet data and a controller for controlling the emulated communications device. The controller operatively connected to the emulated communication device and the controller enables the emulated communications device to emulate the communications device by performing functions that the communication device performs.

Claims

1. A test system for testing a communication device, the communication device configured for transmitting and receiving packet data, the test system residing on a system controller computer, the test system comprising:

an emulated communication device for transmitting and receiving packet data; and

a controller for controlling the emulated communications device, the controller operatively connected to the emulated communication device;

wherein the controller enables the emulated communications device to emulate the communications device by performing functions that the communication device performs.

2. The test system as claimed in claim 1 wherein the communication device is a push to talk over cellular (PoC) wireless telecommunications device.

3. The test system as claimed in claim 1 wherein the functions performed by the emulated communications device include transmission and receipt of packet data.

4. The test system as claimed in claim 2 wherein the controller for controlling the emulated communications device commands the emulated mobile to perform PoC functions.

5. The test system as claimed in claim 4 wherein the PoC functions include a push function.

6. The test system as claimed in claim 4 wherein the PoC functions include a push and hold function.

7. The test system as claimed in claim 4 wherein the PoC functions include a verification function.

8. The test system as claimed in claim 4 wherein the PoC functions include a time delays function.

9. The test system as claimed in claim 4 wherein the PoC functions include a wait for IP assignment function.

10. The test system as claimed in claim 4 wherein the PoC functions include a wait for registration function.

11. A method for testing a communication device, the communication device configured for transmitting and receiving packet data, the method comprising the steps of:

a) providing an emulated communications device configured for transmitting and receiving packet data;

b) obtaining a first data by the communications device;

c) sending a first data in packet data format from the communication device to the emulated communications device;

d) receiving by the emulated communication device the first data sent in packet data format by the communications device;

e) recording by the emulated communications device, the first data sent in packet data format by the communications device;

f) obtaining the first data by the emulated communications device; and

g) comparing the first data obtained by the emulated communications device with the recorded data recorded by the emulated communications device.

12. The method as claimed in claim 11 further comprising the step of:

h) determining whether the first data obtained by the emulated communications device is similar to the recorded data recorded by the emulated communications device.

13. The method as claimed in claim 12 further comprising the step of:

i) reporting the results of the comparing and determining steps to a user.

14. The method as claimed in claim 13 wherein the first data is stored on a system controller computer.

15. The method as claimed in claim 13 wherein the first data is audio data stored in a .wav format.
