Abstract

A system for communicating messages is described. The system includes a server and a gateway. The gateway sends a first message to the server. The first message queries the server to determine whether the server is ready to communicate with the gateway.

Claims

1. A system for communicating messages, said system comprising:

a server; and

a gateway that sends a first message to said server, wherein the first message queries said server to determine whether said server is ready to communicate with said gateway.

2. A system in accordance with claim 1 further comprising a message frame that embeds the first message, wherein the message frame includes a first portion and a second portion, the first portion represented in a hypertext transfer protocol (HTTP) format, and the second portion represented in a format other than the HTTP format.

3. A system in accordance with claim 1 further comprising a message frame that embeds the first message, wherein the message frame includes a first portion and a second portion, the first portion represented in a hypertext transfer protocol (HTTP) format, the second portion represented in a format other than the HTTP format, and the second portion includes the first message.

4. A system in accordance with claim 1 wherein the first message includes a message placed within a web page.

5. A system in accordance with claim 1 further comprising:

a message frame that embeds the first message and includes identifiers of said gateway; and

a wide area network (WAN), wherein said server receives the message frame via said WAN and validates the identifiers.

6. A system in accordance with claim 1 further comprising:

a message frame that embeds the first message and includes a first set of identifiers of said gateway;

a wide area network (WAN), wherein said server receives the message frame via said WAN; and

a database coupled to said server and storing a second set of identifiers, wherein said server matches for at least one time the first set of identifiers with the second set of identifiers, waits if the first set of identifiers do not match the second set of identifiers, and matches a third set of identifiers of said gateway with the second set of identifiers after the wait.

7. A system in accordance with claim 1 further comprising a message frame embedding the first message, wherein said server determines whether a format of the message frame is valid and sends a second message to said gateway if said server determines that the format is invalid, and the second message requests said gateway to re-send the message frame.

8. A system in accordance with claim 1 further comprising a database coupled to said server and including a flag, wherein said server determines whether the flag equals one of a first value and second value and sends a second message to said gateway if the flag equals the first value, and the second message represents that said server is ready to communicate with said gateway.

9. A system in accordance with claim 1 further comprising a database coupled to said server and including a flag, wherein said server determines whether the flag equals one of a first value and second value and sends a second message to said gateway if the flag equals to the second value, and the second message represents that said server is not ready to communicate with said gateway.

10. A system in accordance with claim 1 wherein the first message is sent periodically from said gateway to said server.

11. A system in accordance with claim 1 wherein said server determines if the first message is sent to said server within a time period and generates an error message if said server determines that said gateway did not send the first message within the time period.

12. A system in accordance with claim 1 wherein said gateway is coupled to at least one of a security system, a heating system, a cooling system, and a lighting system.

13. A system for communicating messages, said system comprising:

a server; and

a gateway that sends a message frame to said server, wherein the message frame includes a first portion and a second portion, the first portion converted by applying a first protocol and the second portion of the message frame converted by applying a second protocol that is different from the first protocol, the second portion queries said server to determine whether said server is ready to send a command to said gateway.

14. A system for communicating messages in accordance with claim 13, wherein the first protocol is a hypertext transfer protocol (HTTP).

15. A system for communicating messages in accordance with claim 13 further comprising a wide area network (WAN), wherein said server receives the message frame via said WAN and validates identifiers of said gateway included within the message frame.

16. A method for communicating messages, said method comprising:

coupling a gateway to a server via a network; and

querying the server to determine whether the server is ready to communicate with the gateway.

17. A method in accordance with claim 16 further comprising:

embedding, within a message frame, a message that queries the server, wherein the message queries whether the server is ready to communicate with the gateway, and the message frame includes a first portion and a second portion;

representing the first portion in a hypertext transfer protocol (HTTP) format; and

representing the second portion in a format other than the HTTP format.

18. A method in accordance with claim 16 further comprising:

embedding, within a message frame, a message that queries the server, wherein the message queries whether the server is ready to communicate with the gateway, the message frame includes a first portion and a second portion, the second portion includes the message;

representing the first portion represented in a hypertext transfer protocol (HTTP) format; and

representing the second portion represented in a format other than the HTTP format.

19. A method in accordance with claim 16 further comprising:

embedding, within a web page, a message that queries the server, wherein the message queries whether the server is ready to communicate with the gateway.

20. A method in accordance with claim 16 further comprising:

embedding, within a message frame, a message that queries the server, wherein the message queries whether the server is ready to communicate with the gateway, and the message frame includes identifiers of the gateway;

receiving the message frame from the gateway; and

validating a format of the message frame.
