Abstract

A system for performing information exchange by using a Smart Grid (SG) is provided. The system includes a first device and a second device having SG service types; and an SG Control Point (CP) for transmitting an SG capability request message to the first device and the second device, receiving SG capability response messages from the first device and the second device, matching function sets of the same type to one another if the function sets of the same type are included in the received SG capability response messages from the first device and the second device, and connecting the first device and the second device to one another for the information exchange.

Claims

1. A method for exchanging information by using a Smart Grid (SG), the method comprising:

transmitting, by an SG Control Point (CP), an SG capability request message to a first device and a second device;

receiving SG capability response messages from the first device and the second device;

determining whether function sets of a same type are included in the received SG capability response messages from the first device and the second device;

matching the function sets of the same type to one another; and

connecting the first device and the second device to one another.

2. The method of claim 1, wherein the SG capability response message comprises device types, and wherein the device types include function sets.

3. The method of claim 2, wherein the function sets comprise at least one of a client function and a server function of a corresponding device.

4. The method of claim 1, further comprising:

determining whether predefined minimum inclusion conditions are satisfied based on the received SG capability response messages.

5. The method of claim 4, wherein the predefined minimum inclusion conditions are minimum inclusion conditions defined in Zigbee®

Smart Energy Profile (SEP) 2.0.

6. The method of claim 1, wherein connecting the first device and the second device to one another comprises:

transmitting connection list messages to the first device and the second device;

receiving initialization messages from the first device and the second device, after the first device and the second device have received the connection list messages; and

connecting the first device and the second device to one another based on the connection list messages received by the first device and the second device.

7. The method of claim 6, wherein each of the connection list messages comprises a session ID of a corresponding device, information regarding the function sets of the same type, and an Internet Protocol (IP) address of another device with which the information exchange is to be performed.

8. The method of claim 1, wherein matching the function sets of the same type to one another comprises:

connecting a client module of the function set included in the first device which includes the function sets of the same type with a server module of the function set included in the second device which includes the function sets of the same type.

9. The method of claim 1, wherein matching the function sets of the same type to one another comprises:

connecting a server module of the function set included in the first device with a client module of the function set included in the second device to determine functions of the first device and the second device as a client or a server.

10. A system for exchanging information by using a Smart Grid (SG), the system comprising:

a first device and a second device having SG service types; and

an SG Control Point (CP) for transmitting an SG capability request message to the first device and the second device, receiving SG capability response messages from the first device and the second device, matching function sets of the same type to one another if the function sets of the same type are included in the received SG capability response messages from the first device and the second device, and connecting the first device and the second device to one another for the information exchange.

11. The system of claim 10, wherein the SG capability response message comprises device types, and wherein the device types comprise function sets.

12. The system of claim 11, wherein the function sets comprise information indicating that a corresponding device functions as at least one of a client and a server.

13. An apparatus for exchanging information by using a Smart Grid (SG), the apparatus comprising:

a transmitter for transmitting an SG capability request message to a first device and a second device;

a receiver for receiving SG capability response messages from the first device and the second device;

a controller for determining whether function sets of the same type are included in the received SG capability response messages from the first device and the second device, and matching the function sets of the same type to one another; and

a connector for connecting the first device and the second device to one another.

14. The apparatus of claim 13, wherein the first device and the second device have the same SG service type.

15. The apparatus of claim 13, wherein the SG capability response message comprises device types, and wherein the device types comprise function sets.

16. The apparatus of claim 15, wherein the function sets comprise information indicating that a corresponding device functions as at least one of a client and a server.
