Abstract

An apparatus and method are provided for exchanging data between Universal Plug and Play (UPnP) based devices. The apparatus includes a controller that generates and transmits a request for a parameter to a controlled device, and receives a response to the request from the controlled device; and a fast event data bus module that establishes a fast event data transmission path, based on information included in the response, and receives fast event data.

Claims

1. An apparatus for exchanging data between Universal Plug and Play (UPnP) based devices, the apparatus comprising:

a controller that generates a request for a parameter; and

an interface module that transmits the request to a controlled device over a request transmission path and receives a response to the request from the controlled device,

wherein the controller establishes a bi-directional event data transmission path different from the request transmission path with the controlled device based on information included in the response, and controls the interface module to receive event data associated with the requested parameter from the controlled device through the event data transmission path by using UPnP, and

wherein the information included in the response comprises a period for transmission of the parameter, and a duration for transmission of the parameter.

2. The apparatus of claim 1, wherein the request for the parameter comprises:

a parameter name of the parameter;

a period type for reception of the parameter;

a period for reception of the parameter;

a duration type for reception of the parameter; and

a duration for reception of the parameter.

3. The apparatus of claim 2, wherein the response to the request further comprises,

an IDentifier (ID) for distinguishing the parameter;

and

an address for transmission of the parameter.

4. The apparatus of claim 2, wherein the request for the parameter further comprises an address for reception of the parameter.

5. The apparatus of claim 4, wherein the response to the request further comprises:

an IDentifier (ID) for distinguishing the parameter.

6. The apparatus of claim 1, wherein the event data comprises:

a Query IDentifier (ID) for distinguishing the parameter; and

a data value corresponding to the parameter.

7. The apparatus of claim 1, wherein the event data comprises a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.

8. An apparatus for exchanging data between Universal Plug and Play (UPnP) based devices, the apparatus comprising:

an interface module that receives a request over a request transmission path for a parameter from a control point, and transmits a response to the request to the control point; and

a controller that establishes a bi-directional event data transmission path different from the request transmission path with the control point based on information included in the request, and controls the interface module to transmit event data associated with the requested parameter to the control point through the event data transmission path by using UPnP, and

wherein the information included in the response comprises a period for transmission of the parameter, and a duration for transmission of the parameter.

9. The apparatus of claim 8, wherein the request for the parameter comprises:

a parameter name of the parameter;

a period type for reception of the parameter;

a period for reception of the parameter;

a duration type for reception of the parameter; and

a duration for reception of the parameter.

10. The apparatus of claim 9, wherein the response to the request further comprises:

an IDentifier (ID) for distinguishing the parameter; and

an address for transmission of the parameter.

11. The apparatus of claim 9, wherein the request for the parameter further comprises an address for reception the parameter.

12. The apparatus of claim 11, wherein the response to the request further comprises:

an IDentifier (ID) for distinguishing the parameter.

13. The apparatus of claim 8, wherein the event data comprises:

a Query IDentifier (ID) for distinguishing the parameter; and

a data value corresponding to the parameter.

14. The apparatus of claim 8, wherein the event data comprises a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.

15. A method of exchanging data between Universal Plug and Play (UPnP) based devices, the method comprising:

generating, by a control point, a request for a parameter;

transmitting the request to a controlled device over a request transmission path;

receiving a response to the request from the controlled device;

establishing a bi-directional event data transmission path different from the request transmission path with the controlled device based on information included in the response; and

receiving event data associated with the requested parameter from the controlled device through the event data transmission path by using UPnP, and

wherein the information included in the response comprises a period for transmission of the parameter, and a duration for transmission of the parameter.

16. The method of claim 15, further comprising:

receiving, by the controlled device, the request for the parameter from the control point;

generating the response to the requesting;

transmitting the response to the control point;

establishing the event data transmission path with the control point; and

transmitting the event data to the control point through the event data transmission path.

17. The method of claim 15, wherein the request for the parameter includes a parameter name of the parameter, a period type for reception of the parameter, a period for reception of the parameter, a duration type for reception of the parameter, and a duration for reception of the parameter.

18. The method of claim 15, wherein the response to the request further includes an IDentifier (ID) for distinguishing the parameter, and an address for transmission of the parameter.

19. method of claim 15, wherein the event data includes a Query IDentifier for distinguishing the parameter and a data value corresponding to the parameter.

20. The method of claim 15, wherein the event data includes a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.
