Method for providing service through solution server in security environment, and apparatus and system for performing the same

1. A system for providing a solution service to an image forming apparatus, the system comprising:

a message server configured to communicate with a solution server and an image forming apparatus, a first firewall being provided between the image forming apparatus and the message server to restrict access from the message server to the image forming apparatus, and a second firewall being provided between the solution server and the message server to restrict access from the message server to the solution server,

wherein the message server

receives a job request from the solution server for the image forming apparatus by using a message protocol,

receives a first pull request from the image forming apparatus requesting the message server to transmit the job request, received from the solution server, to the image forming apparatus, in response to the first pull request from the image forming apparatus,

receives a job response representing a result of performing the job by the image forming apparatus according to the job request, the received job response having been converted into a data type of the message protocol,

receives a second pull request from the solution server, and

transmits the received job response to the solution server in response to the second pull request.

2. The system of claim 1 , wherein

the message server stores the received job request, and

the received job request having been converted into the data type of the message protocol by the solution server.

3. The system of claim 2 , wherein

the message server transmits the stored job request to the image forming apparatus in response to the first pull request.

4. The system of claim 1 , wherein

the message server stores the received job response, and

the received job response having been converted into the data type of the message protocol by the image forming apparatus.

5. The system of claim 1 , wherein the message server is implemented as a proxy server relaying a communication between the image forming apparatus and the solution server.

6. The system of claim 1 , wherein the message server comprises:

a first message server configured to communicate with the solution server; and

a second message server configured to communicate with the image forming apparatus and the first message server,

wherein

the first message server receives the job request from the solution server and transmits the job request transmitted by the solution server to the second message server,

the second message server receives the job response from the image forming apparatus and transmits the job response transmitted by the image forming apparatus to the first message server,

the second message server transmits the job request to the image forming apparatus, in response to the first pull request from the image forming apparatus, and

the first message server transmits the received job response to the solution server, in response to the second pull request from the solution server.

7. The system of claim 1 , wherein the message server communicates with the image forming apparatus through a message server connection agent embedded in or implemented outside the image forming apparatus.

8. The system of claim 1 , wherein

the message server receives the job request, the first pull request, the job response, and the second pull by using a same message protocol, and

the same message protocol includes XMPP-type data.

9. An image forming apparatus, comprising:

a communication interface configured to communicate with a solution server through a message server;

a user interface (UI) configured to provide a UI for a solution application installed in the solution server and to receive a user input;

a job performing apparatus configured to perform an image forming job; and

a controller configured:

to control the communication interface to transmit a first pull request to the message server requesting the message server to transmit a job request transmitted to the message server from the solution server, and to receive the job request from the message server in response to the pull request,

to control the job performing apparatus to perform the image forming job corresponding to the job request, and

to control the communication interface to transmit a job response to the message server representing a result of performing the image forming job according to the job request, for the message server to transmit the job response to the solution server in response to a second pull request job request transmitted to the message server from the solution server,

wherein

a first firewall is provided between the image forming apparatus and the message server to restrict access from the message server to the image forming apparatus, and

a second firewall is provided between the solution server and the message server to restrict access from the message server to the solution server.

10. The image forming apparatus of claim 9 , wherein

the controller controls the communication interface to periodically transmit the first pull request to the message server and the communication interface receives the job request from the message server in response to the first pull request.

11. The image forming apparatus of claim 9 , wherein the controller converts the job response into a data type of a message protocol, and controls the communication interface to transmit the converted job response to the message server.

12. A method for providing a solution service to an image forming apparatus by a message server, the method comprising:

receiving, from a solution server, a job request for the image forming apparatus by using a message protocol;

receiving, from the image forming apparatus, a first pull request requesting the message server to transmit the job request transmitted from the solution server;

transmitting, to the image forming apparatus, the job request transmitted from the solution server in response to the first pull request from the image forming apparatus;

receiving a job response representing a result of performing the job by the image forming apparatus according to the job request, the received job response having been converted into a data type of the message protocol;

receiving a second pull request from the solution server; and

transmitting the received job response to the solution server in response to the second pull request,

wherein

a first firewall is provided between the image forming apparatus and the message server to restrict access from the message server to the image forming apparatus, and

a second firewall is provided between the solution server and the message server to restrict access from the message server to the solution server.

13. The method of claim 12 , further comprising:

storing the received job request, the received job request having been converted into the data type of the message protocol by the solution server.

14. The method of claim 13 , wherein

the transmitting of the job request, to the image forming apparatus, comprises transmitting the job request stored in the message server, in response to the first pull request.

15. The method of claim 12 , further comprising:

storing the received job response, the received job response having been converted into the data type of the message protocol by the image forming apparatus.
