Method and system for automatically connecting calls of voice over internet protocol (VOIP) service

1. A method of automatically connecting a Voice over Internet Protocol (VoIP) call in an electronic device implemented by a computer, the method comprising:

setting a specific counterpart among counterparts capable of making the VoIP call over a network as an automatic connection target;

executing a program including a function of providing the VoIP call;

determining that a corresponding program is being executed on an electronic device of the automatic connection target;

automatically connecting the VoIP call with the automatic connection target in response to determining that the corresponding program is being executed on the electronic device of the automatic connection target without performing a calling operation and an acceptance operation for a call between a user of the electronic device and the automatic connection target;

providing state information associated with the automatic connection target through a screen display on the electronic device; and

maintaining the call between the user and the automatic connection target by automatically connecting the VoIP call without a separate calling operation while the program and the corresponding program are being executed,

wherein the providing comprises displaying a call connection state with the automatic connection target at all times during the maintaining of the call,

wherein the setting the specific counterpart among counterparts is independent from the providing the VoIP call, and

wherein the setting the specific counterpart comprises setting the automatic connection target based on a call history accumulated for each of the counterparts.

2. The method of claim 1 , wherein the setting comprises setting the specific counterpart selected by the user from among the counterparts capable of making the VoIP call as the automatic connection target.

3. The method of claim 1 , wherein the setting comprises:

recommending at least one counterpart among the counterparts capable of making the VoIP call based on the call history accumulated for each of the counterparts; and

setting the specific counterpart selected by the user from among the recommended at least one counterparts as the automatic connection target.

4. The method of claim 3 , wherein the setting comprises updating the recommending at least one counterpart among the counterparts capable of making the VoIP call after a period of time based on the call history accumulated during the period of time.

5. The method of claim 1 , wherein the connecting comprises immediately connecting the call between the user and the specific counterpart in response to executing the program on the electronic device of the specific counterpart and setting the user and the specific counterpart as mutual automatic connection targets.

6. The method of claim 1 , wherein the providing comprises displaying information associated with the automatic connection target using a separate display element on a user interface screen of the program.

7. The method of claim 1 , wherein the call connection state with the automatic connection target is provided on a user interface screen of the program.

8. The method of claim 1 , wherein the call connection state with the automatic connection target is displayed in an icon in a floating state on a screen displayed on the electronic device.

9. The method of claim 8 , wherein the icon indicating the call connection state with the automatic connection target includes a shortcut function of redirecting to a call screen or a chat screen with the automatic connection target.

10. A non-transitory computer-readable recording medium storing instructions that, when executed by a processor of an electronic device, cause the processor to implement a method of automatically connecting a Voice over Internet Protocol (VoIP) call in conjunction with a computer implemented by a computer, the method comprising:

setting a specific counterpart among counterparts capable of making the VoIP call over a network as an automatic connection target;

executing a program including a function of providing the VoIP call;

determining that a corresponding program is being executed on an electronic device of the automatic connection target;

automatically connecting the VoIP call with the automatic connection target in response to determining that the corresponding program is being executed on the electronic device of the automatic connection target without performing a calling operation and an acceptance operation for a call between a user of the electronic device and the automatic connection target;

providing state information associated with the automatic connection target through a screen display on the electronic device; and

maintaining the call between the user and the automatic connection target by automatically connecting the VoIP call without a separate calling operation while the program and the corresponding program are being executed,

wherein the providing comprises displaying a call connection state with the automatic connection target at all times during the maintaining of the call,

wherein the setting the specific counterpart among counterparts is independent from the providing the VoIP call, and

wherein the setting the specific counterpart comprises setting the automatic connection target based on a call history accumulated for each of the counterparts.

11. A system for automatically connecting a Voice over Internet Protocol (VoIP) call in an electronic device implemented by a computer, the system comprising:

one or more processors configured to execute computer-readable instructions,

wherein the one or more processors are:

configured to set a specific counterpart among counterparts capable of making the VoIP call over a network as an automatic connection target;

configured to execute a program including a function of providing the VoIP call;

configured to determine that a corresponding program is being executed on the an electronic device of the automatic connection target;

configured to automatically connect the VoIP call with the automatic connection target in response determining that the corresponding program is being executed on the electronic device of the automatic connection target without performing a calling operation and an acceptance operation for a call between a user of the electronic device and the automatic connection target;

configured to provide state information associated with the automatic connection target through a screen display on the electronic device; and

configured to maintain the call between the user and the automatic connection target by automatically connecting the VoIP call without a separate calling operation while the program and the corresponding program are being executed,

wherein the providing comprises displaying a call connection state with the automatic connection target at all times during the maintaining of the call,

wherein the setting of the specific counterpart among counterparts is independent from the providing the VoIP call, and

wherein the setting of the specific counterpart comprises setting the automatic connection target based on a call history accumulated for each of the counterparts.

12. The system of claim 11 , including a target setter,

wherein the target setter is configured to set the specific counterpart selected by the user from among the counterparts capable of making the VoIP call as the automatic connection target.

13. The system of claim 11 , including a target setter,

wherein the target setter is configured to set the automatic connection target based on the call history accumulated for each of the counterparts.

14. The system of claim 11 , wherein the one or more processors are configured to recommend at least one counterpart among the counterparts capable of making the VoIP call based on the call history accumulated for each of the counterparts, and to set the specific counterpart selected by the user from among the recommended counterparts as the automatic connection target.

15. The system of claim 11 , wherein the one or more processors are configured to immediately connect the VoIP call between the user and the specific counterpart in response to executing the program on the electronic device of the specific counterpart and setting the user and the specific counterpart as mutual automatic connection targets.

16. The system of claim 11 , wherein the one or more processors are configured to display information associated with the automatic connection target using a separate display element on a user interface screen of the program.

17. The system of claim 11 , wherein the one or more processors are configured to display the call connection state with the automatic connection target on a user interface screen of the program.
