Abstract

A method and device of enabling interoperation between different devices over a network are provided. A test code corresponding to a service to be performed using device information received from a service providing device in a network is generated, the test code is transmitted to the service providing device, a result of the test code execution is received from the service providing device, and interoperability with the service providing device is determined with respect to the service by using the result of the execution of the test code. An environment suitable for interoperation with the service providing device is established when interoperation with the service providing device is possible.

Claims

1. A method of enabling interoperation between different devices of a network, the method comprising:

generating a test code corresponding to a service to be performed;

transmitting the test code to a service providing device;

receiving a test code execution result from the service providing device;

determining interoperability with the service providing device with respect to the service to be performed by using the test code execution result; and

establishing an environment suitable for interoperation with the service providing device.

2. The method of claim 1, wherein determining the interoperability comprises:

transmitting the test code to the service providing device;

receiving the test code execution result from the service providing device;

generating a function expansion module necessary for the service providing device;

performing the interoperation by using the test code execution result;

including the function expansion module in the test code;

transmitting the test code to the service providing device; and

determining the interoperability by using the test code execution result received from the service providing device, the service providing device being dynamically expanded by the function expansion module.

3. The method of claim 2, wherein the generating of the function expansion module comprises searching a table for a function expansion module corresponding to the test code execution result received from the service providing device.

4. The method of claim 2, wherein the function expansion module is transmitted as a mobile code.

5. The method of claim 1, further comprising, when the result of the test code execution is a failure, repeating the transmitting of the test code and receiving the test code execution result at least a certain number of times, wherein the test code is changed for each repetition.

6. The method of claim 1, wherein when the test code execution result is not received from the service providing device after a period of time, the result of the test code execution is determined a failure.

7. The method of claim 1, wherein the network includes an ad hoc network.

8. The method of claim 1, wherein the generating of the test code comprises searching a table for a test code corresponding to the service to be performed and the device information received from the service providing device, wherein the table stores every type of test code.

18. The method of claim 1, wherein the test code is generated using device information received from a service providing device.

24. The method of claim 3, wherein the table stores every type of function expansion module.

9. A network device comprising:

a test code generation unit for generating a test code corresponding to a service to be performed using device information received from a service providing device in a network;

an interoperability determination unit for transmitting the test code to the service providing device, receiving a test code execution result from the service providing device, and determining interoperability with the service providing device with respect to the service to be performed by using the test code execution result; and

an environment establishment unit for establishing an environment suitable for interoperation with the service providing service.

10. The device of claim 9, further comprising:

a function expansion module generation unit for generating a function expansion module necessary for the service providing device and performing the interoperation by using the test code execution result, including the function expansion module in the test code and transmitting the test code to the service providing device.

11. The device of claim 10, wherein the interoperability determination unit determines interoperability by using the test code execution result received from the service providing device of which a function is dynamically expanded using the function expansion module.

12. The device of claim 10, wherein the function expansion module generation unit generates a function expansion module corresponding to the test code execution result received from the service providing device.

13. The device of claim 10, wherein the function expansion module is transmitted to the service providing device as a mobile code.

14. The device of claim 9, wherein the network device, when the result of the test code execution is a failure, repeats transmitting the test code and receiving the test code execution result at least a certain number of times and wherein the test code is changed for each repetition.

15. The device of claim 9, wherein when the test code execution result is not received from the service providing device for a period of time, the network device determines that the result of the test code execution is a failure.

16. The device of claim 9, wherein the network includes an ad hoc network.

17. The device of claim 9, wherein the test code generation unit searches a table for a test code corresponding to the service to be performed and device information received from the service providing device, and generates the test code.

25. The device of claim 12, wherein the function expansion module is generated by searching a table storing every type of function expansion module.

26. The device of claim 17, wherein the table stores every type of test code.

19. A computer readable medium having stored thereon instructions for enabling interoperation between different devices of a network, the instructions comprising:

a first set of instructions for generating a test code corresponding to a service to be performed;

a second set of instructions for transmitting the test code to a service providing device;

a third set of instructions for receiving a test code execution result from the service providing device;

a fifth set of instructions for establishing an environment suitable for interoperation with the service providing device.

20. The instructions of claim 19, wherein the set of instructions for determining the interoperability comprise:

a sixth set of instructions for transmitting the test code to the service providing device;

a seventh set of instructions for receiving the test code execution result from the service providing device;

an eighth set of instructions for generating a function expansion module necessary for the service providing device;

a ninth set of instructions for performing the interoperation by using the test code execution result;

a tenth set of instructions for including the function expansion module in the test code and transmitting the test code to the service providing device; and

an eleventh set of instructions for determining the interoperability by using the test code execution result received from the service providing device, the service providing device being dynamically expanded by the function expansion module.

21. The instructions of claim 20, wherein the eighth set of instructions for generating of the function expansion module comprise a set of instructions for searching a table for a function expansion module corresponding to the test code execution result received from the service providing device.
