Abstract

An image forming apparatus and a communication connection method thereof. The communication connection method includes: receiving, by a first image forming apparatus, packet information from a second image forming apparatus; measuring, by the first image forming apparatus, a signal strength of the received packet information; and changing a connection reference strength of the first image forming apparatus based on the measured signal strength.

Claims (31)

1. A communication connection method comprising:

receiving, by a first image forming apparatus, a signal including a data packet from a second image forming apparatus:

the first image forming apparatus having a first connection reference strength level indicating a first connection boundary from the first image forming apparatus, the first image forming apparatus being configured to be connectable to devices located within the first connection boundary, and

the second image forming apparatus having a second connection boundary from the second image forming apparatus, the second image forming apparatus being configured to be connectable to devices located within the second connection boundary;

determining, by the first image forming apparatus, a signal strength of the received signal; and

changing, by the first image forming apparatus, the first connection reference strength level based on the determined signal strength, so that the first connection boundary of the first image forming apparatus does not overlap with the second connection boundary of the second image forming apparatus.

2. The communication connection method of claim 1 , further comprising broadcasting, by the first image forming apparatus, a signal including a data packet from the first image forming apparatus to one or more devices among the devices located within the first connection boundary.

3. The communication connection method of claim 2 , wherein the broadcasting of the signal from the first image forming apparatus further comprises increasing a packet transmission time interval when the first image forming apparatus does not receive a connection request for a first predetermined time.

4. The communication connection method of claim 3 , further comprising scanning a device among the one or more devices so as to discover the device, when the first image forming apparatus does not receive the connection request for a second predetermined time.

5. The communication connection method of claim 3 , further comprising changing the first image forming apparatus from an awake mode to a sleep mode when the first image forming apparatus does not receive the connection request for a second predetermined time.

6. The communication connection method of claim 5 , further comprising, changing the first image forming apparatus from the sleep mode to the awake mode when the first image forming apparatus receives an input to change to the awake mode while the first image forming apparatus is in the sleep mode.

7. The communication connection method of claim 1 , wherein a device among the devices located within the first connection boundary is set as a connection target device by the first image forming apparatus, when a signal strength of a connection request to be received from the device is greater than or equal to the first connection reference strength level.

8. The communication connection method of claim 1 , wherein the first connection reference strength level of the first image forming apparatus after the changing is greater than the first connection reference strength level of the first image forming apparatus before the changing.

9. The communication connection method of claim 2 , further comprising receiving a connection request from the one or more devices in response to the broadcasted signal by the first image forming apparatus.

10. The communication connection method of claim 9 , further comprising performing a procedure of using a communication service with the one or more devices when the one or more devices are set as a one or more connection target devices.

11. A first image forming apparatus comprising:

a communicator configured to receive a signal including a data packet from a second image forming apparatus:

the first image forming apparatus having a first connection reference strength level indicating a first connection boundary from the first image forming apparatus, the first image forming apparatus being configured to be connectable to devices located within the first connection boundary, and

the second image forming apparatus having a second connection boundary from the second image forming apparatus, the second image forming apparatus being configured to be connectable to devices located within the second connection boundary; and

a controller configured to:

determine a signal strength of the received signal, and

change the first connection reference strength level based on the determined signal strength, so that the first connection boundary of the first image forming apparatus does not overlap with the second connection boundary of the second image forming apparatus.

12. The first image forming apparatus of claim 11 , wherein the communicator is further configured to broadcast a signal including a data packet from the first image forming apparatus to one or more devices among the devices located within the first connection boundary.

13. The first image forming apparatus of claim 12 , wherein the controller is further configured to increase a packet transmission time interval when the communicator does not receive a connection request for a first predetermined time.

14. The first image forming apparatus of claim 13 , wherein the controller is set to scan a device among the one or more devices so as to discover the device, when the communicator does not receive the connection request for a second predetermined time.

15. The first image forming apparatus of claim 13 , wherein the controller is further configured to change the communicator from an awake mode to a sleep mode when the communicator does not receive the connection request for a second predetermined time.

16. The first image forming apparatus of claim 15 , wherein the controller is set to change the communicator from the sleep mode to an awake mode when the first image forming apparatus receives an input to change to the awake mode while the first image forming apparatus is in the sleep mode.

17. The first image forming apparatus of claim 11 , wherein a device among the devices located within the first connection boundary is set as a connection target device by the first image forming apparatus, when a signal strength of a connection request to be received from the device is greater than or equal to the first connection reference strength level.

18. The first image forming apparatus of claim 17 , wherein the first connection reference strength level of the first image forming apparatus after a change in the first connection reference strength is greater than the first connection reference strength level of the first image forming apparatus before the change in the first connection reference strength level.

19. The first image forming apparatus of claim 12 , wherein the communicator is further configured to receive a connection request from the one or more devices in response to the broadcasted signal.

20. The first image forming apparatus of claim 19 , wherein the controller is set to perform a procedure of using a communication service with the one or more devices when the one or more devices are set as a one or more connection target devices.
