Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a service providing system for providing a three-way phone dialing service according to an embodiment of the present invention. 1 illustrates a service providing system 100, a first communication network 110 to a fourth communication network 140, a calling terminal 150, and a called terminal 160 according to the present embodiment.

The service providing system 100 provides a dialing service of a third party call method. First, the service providing system 100 may interwork with the first communication network 110 and the second communication network 120.

In this case, the service providing system 100 may receive a three-way call dialing request through the first communication network 110. For example, the first communication network 110 may be an internet network. In this case, when a service user requests a call through a terminal of a service user capable of connecting to the wired / wireless internet, a call request is transmitted to the service providing system 100 through the first communication network 110, which is an internet network. Can be. Here, the service user may be the same user as the calling user of the calling terminal 150, or may be different users. Here, the terminal of the service user may include one of all devices capable of connecting to the wired / wireless Internet such as a mobile terminal as well as a PC. In this case, the service user may request a call through an application executed on the terminal, a web application provided on the web, or a service provided on a web page visited by the terminal. For example, the service providing system 100 may provide an application, a web application, or a website including a user interface for requesting a call over the Internet, and the service user may access the Internet provided through a terminal. The user can download a call and make a call through the application's user interface or visit a provided website and request a call through the user interface of the web application or through a link established on the website.

In addition, the service providing system 100 may call the calling terminal 150 or the called terminal 160 through the second communication network 120. For example, the second communication network 120 may be an Internet Telephony Service Provider (ITSP) network. In this case, the second communication network 120 may again interwork with the third communication network 130 available to the calling terminal 150 and the fourth communication network 140 available to the called terminal 160. For example, the third communication network 130 may be an outgoing telephone network, and the fourth communication network 140 may be an incoming telephone network.

That is, when the service providing system 100 calls the calling terminal 150 or the called terminal 160 through the second communication network 120, the second communication network 120 calls the calling terminal 150 or the called terminal 160. The call of the service providing system 100 may be transmitted to the calling terminal 150 or the called terminal 160 through a communication network corresponding to the call.

In this case, when the service providing system 100 receives a call request, the service providing system 100 first calls the called terminal 160 and calls the calling terminal 150 after a preset waiting time to call the calling terminal 150 and the called terminal ( By inducing a call connection between the 160, not only the waiting time of the calling user can be minimized, but also unnecessary call costs generated while the calling terminal 150 is waiting can be reduced.

In addition, when the called terminal 160 is connected during the preset waiting time, the service providing system 100 calls the calling terminal 150 instead of waiting for the preset waiting time to end, thereby calling the calling user and the called user. Minimize the latency of your liver.

In addition, the service providing system 100 may call the called terminal 160 first and call the calling terminal 160 only when the called terminal 160 is in a ringing state. That is, when the called terminal 160 is not ringing, there is no need to call the calling terminal 150. That is, the service providing system 100 notifies the service user that the terminating terminal 160 is in a busy state or an error state through the first communication network 110 when the terminating terminal 160 is in a busy state or an error state. You can terminate the service. For example, the service providing system 100 may terminate the service after transmitting a message for notifying that the called terminal 160 is in a busy state or an error state to the service user terminal through the first communication network 110. .

2 is an example of a service providing method when the called terminal is in a ringing state according to an embodiment of the present invention. 2 shows a terminal 210, a calling terminal 220, a service providing system 230, and a called terminal 240.

The terminal 210 may include a wired terminal or a wireless terminal of a service user requesting a three-way phone dialing service through a user interface provided to a service user such as a dial button by accessing the Internet. That is, when the service user clicks the dial button through the terminal 210, the terminal 210 may request 251 to make a call to the service providing system 230.

In this case, the service providing system 230 calls the called terminal 240 to attempt an incoming connection 252 with the called terminal 240 and checks the state of the called terminal 240 (253).

When the confirmed state of the called terminal 240 is a ringing state, the service providing system 230 waits 254 for a preset waiting time.

After the waiting time, the service providing system 230 calls the calling terminal 220 and attempts an outgoing connection 255 with the calling terminal 220.

At this time, when both the calling terminal 220 and the called terminal 240 are connected, a call 256 is made between the calling terminal 220 and the called terminal 240. In other words, when both the calling user of the calling terminal 220 and the called user of the called terminal 240 receive a call, the calling user and the called user can call each other through the calling terminal 220 and the called terminal 240. It becomes a state.

If the called user of the called terminal 240 receives a call and the called terminal 240 is connected first during the waiting 254 for a preset waiting time, an answer is delivered to the service providing system 230. The service providing system 230 may end the standby state and immediately attempt the outgoing connection 255 to the calling terminal 220 by calling the calling terminal 220 even if it is during the preset waiting time.

3 is an example of a service providing method when a called terminal is in a busy state or an error state according to an embodiment of the present invention. 3 illustrates a terminal 310, a calling terminal 320, a service providing system 330, and a called terminal 340.

The terminal 310 may include a wired terminal or a wireless terminal of a service user requesting a three-way call type dialing service through a user interface provided to a service user such as a dial button by accessing the Internet. That is, when the service user clicks the dial button through the terminal 310, the terminal 310 may request 351 to make a call to the service providing system 330.

In this case, the service providing system 330 calls the called terminal 340 to attempt an incoming connection 352 with the called terminal 340, and checks the state of the called terminal 340 (353).

If the confirmed state of the called terminal 340 is in a call state or an error state, the service providing system 330 notifies the terminal 310 that the called terminal 340 is in a call or error state 354 and then provides a service. End 355.

4 is a block diagram illustrating an internal configuration of a service providing system according to an embodiment of the present invention. The service providing system 400 according to the present embodiment is a system for providing a third party call type dialing service. As shown in FIG. 4, the call requesting unit 410 and the terminal calling unit 420 are illustrated. ), The response signal receiver 430 and the call connection unit 440 may be included. In this case, the response signal receiver 430 may be selectively included in the service providing system 400 as needed.

The call request receiving unit 410 receives a call request generated through a terminal of a service user. For example, as described with reference to FIG. 1, the service providing system 400 may include a user whose service site accesses a specific site through a first communication network 110 such as an internet network and a wired terminal or a wireless terminal. A dialing request generated by clicking an interface (to generate a dialing request) may be received via the dialing request receiving unit 410. Here, the terminal of the service user may include one of all devices capable of connecting to the wired / wireless Internet such as a mobile terminal as well as a PC. In this case, the service user may generate a call request through an application executed on the terminal, a web application provided on the web, or a service provided on a web page visited by the terminal.

The terminal calling unit 420 calls the called terminal according to the call request and calls the calling terminal according to the state of the called terminal. Here, the state of the called terminal includes a ringing state in which a call signal is normally transmitted to the called terminal, a busy state indicating that the called terminal is busy, and an error state in which the called terminal cannot be connected. can do. At this time, the terminal caller 420 may call the calling terminal when the state of the called terminal is ringing.

In this way, the terminal calling unit 420 calls the called terminal first, and then calls the calling terminal later, thereby reducing the waiting time of the calling user, which is the user of the calling terminal, and reducing the communication cost incurred according to the waiting time of the calling user. In addition, it is possible to reduce the load on the communication network to utilize the resources of the communication network more efficiently. In this case, in order to maximize the effect caused by calling the called terminal first, the terminal calling unit 420 calls the called terminal, and checks the state of the called terminal to determine the state of the called terminal ringing, the preset The calling terminal can be called after waiting for the waiting time. At this time, the waiting time may be preset based on empirical results.

In addition, the terminal calling unit 420 calls the called terminal and checks the state of the called terminal to provide data for notifying that the called terminal is in a busy state or an error state when the called terminal is in a busy state or an error state. It can transmit to the terminal of the service user. In this case, after the data is transmitted, the dialing service may be immediately terminated.

The response signal receiving unit 430 receives a response signal transmitted through a communication network when connected to the calling terminal. For example, after calling the called terminal, when connected with the called terminal, a response signal may be transmitted to the service providing system 400 through a communication network, and the response signal receiving unit 430 may receive the transmitted response signal. Can be. In this case, when the response signal for the called terminal is received within the preset waiting time, the terminal calling unit 420 may call the calling terminal immediately regardless of the preset waiting time. That is, in order to minimize the time for which the called user of the called terminal waits for a call, the terminal caller 420 may call the calling terminal immediately even during the waiting time when connected to the called terminal within the waiting time. At this time, the called user may be provided with the announcement until connected to the calling terminal.

Here, the communication network to which the response signal is transmitted may include an outgoing telephone network of the outgoing telephone and an Internet Telephony Service Provider (ITSP) network interworking with the incoming telephone network of the incoming telephone.

The call connection unit 440 connects a call between the called terminal and the calling terminal. That is, when the called terminal and the calling terminal are respectively connected to the service providing system 400, the call connection unit 440 may connect the called terminal and the calling terminal to each other to enable a call between the called terminal and the calling terminal.

5 is a flowchart illustrating a service providing method according to an embodiment of the present invention. The service providing method according to the present embodiment may be performed by the service providing system 400 described with reference to FIG. 4. In this case, step 530 illustrated in FIG. 5 may be selectively performed as necessary.

In operation 510, the service providing system 400 receives a call request generated through a terminal of a service user. For example, as described with reference to FIG. 1, the service providing system 400 may include a user whose service site accesses a specific site through a first communication network 110 such as an internet network and a wired terminal or a wireless terminal. A dialing request, generated by clicking on the interface (to generate a dialing request), may be received via step 510. Here, the terminal of the service user may include one of all devices capable of connecting to the wired / wireless Internet such as a mobile terminal as well as a PC. In this case, the service user may generate a call request through an application executed on the terminal, a web application provided on the web, or a service provided on a web page visited by the terminal.

In step 520, the service providing system 400 calls the called terminal according to the call request, and calls the calling terminal according to the state of the called terminal. Here, the state of the called terminal may include a ringing state in which a call signal is normally transmitted to the called terminal, a busy state indicating a state in which the called terminal is in a call, and an error state in which the called terminal cannot be connected. In this case, the service providing system 400 may call the calling terminal when the state of the called terminal is ringing in step 520.

In this way, the service providing system 400 calls the called terminal first, and then calls the calling terminal later, thereby reducing the waiting time of the calling user, which is the user of the calling terminal, and reducing the communication cost incurred according to the waiting time of the calling user. In addition, it is possible to reduce the load on the communication network to utilize the resources of the communication network more efficiently. In this case, in order to maximize the effect caused by calling the called terminal first, the service providing system 400 calls the called terminal, and checks the state of the called terminal, if the state of the called terminal is ringing, the preset The calling terminal can be called after waiting for the waiting time. At this time, the waiting time may be preset based on empirical results.

In addition, the service providing system 400 calls the called terminal and checks the state of the called terminal to provide data for notifying that the called terminal is in a busy state or an error state when the state of the called terminal is a busy state or an error state. It can transmit to the terminal of the service user. In this case, after the data is transmitted, the dialing service may be immediately terminated.

In operation 530, the service providing system 400 receives a response signal transmitted through a communication network when connected to the calling terminal. For example, after calling the called terminal, when connected with the called terminal, a response signal may be transmitted to the service providing system 400 through a communication network, and in step 530, the service providing system 400 is delivered. A response signal can be received. In this case, when the response signal for the called terminal is received within the preset waiting time, the service providing system 400 may directly call the calling terminal regardless of the preset waiting time. That is, in step 520, when the called terminal is called and a response signal to the called terminal is received while waiting for the waiting time, the service providing system 400 may immediately call the calling terminal. That is, in order to minimize the time for which the called user of the called terminal waits for a call, the service providing system 400 may directly call the calling terminal even during the waiting time when connected to the called terminal within the waiting time. At this time, the called user may be provided with the announcement until connected to the calling terminal.

Here, the communication network to which the response signal is transmitted may include an ITSP network interworking with the outgoing telephone network of the outgoing telephone and the incoming telephone network of the incoming telephone.

In operation 540, the service providing system 400 connects a call between the called terminal and the calling terminal. That is, when the called terminal and the calling terminal are respectively connected to the service providing system 400, the service providing system 400 may connect the called terminal and the calling terminal to each other to enable a call between the called terminal and the calling terminal.

As such, according to embodiments of the present invention, since the service provider first checks the state of the called terminal and then calls the calling terminal, the service provider can avoid wasting money by ending the service without unnecessary connection according to the state of the called terminal. For example, the waiting time considering the time taken by the called user can be reduced by minimizing the time difference between the calling user and the called user. In addition, when the called terminal is in a call state or an error state, the service user can immediately check whether there is an abnormality by transmitting a message for notifying that the called terminal is in a call state or an error state to the service user and ending the service.
