1 is a block diagram of an Internet phone call connection system according to an embodiment of the present invention. The Internet phone call connection system is composed of a sending client system 100, a call setup server 250, an exchange 350 and a receiving telephone 600.

The transmitting client system 100 receives the call setup server Uniform Resource Locator (URL) information and the receiving telephone identification number from the call setup server, and performs a call with the receiving telephone 600 through the exchange 350. to be. The transmitting client system 100 has a hardware configuration such as a personal computer or notebook computer having a general input / output device, a mobile phone, or an electronic device connected to the Internet. The sending client system 100 connects to a web browser and call setup server 250 that interprets and displays Hyper Text Markup Language (HTML), sets up a call, connects to a packet network, and performs a voice or video call of a VoIP soft phone. Has a user agent.

 A user agent is a software module that is temporarily or permanently installed in the memory of a sending client system during setup or ongoing call, and is a software implementable module called flash. In other words, the service can be implemented by using general-purpose general purpose flash software. In this case, the call setup communication server 210 is provided with a flash application to perform most call setup operations such as assigning a DN number usable at the exchange instead of a user agent. Therefore, in the transmitting client system 100, a simple user agent which works only with a flash phone function by interworking with a flash agent may be temporarily installed even if the user does not take any action only when the phone is called.

The user agent is provided with the URL information of the call setup server 250 at the moment the sender clicks on the telephone icon or button (showing the telephone connection) displayed in the web browser, connects with the call setup server 250 to set up the call, The module proceeds a call with the receiving telephone 600 connected to the exchange 350 and stops the call when the call between the sender and the receiver ends.

The call setup server 250 includes a call setup web server 200 and a call setup communication server 210. The call setup web server 200 displays the telephone connection indication in which the URL and the LN of the call setup communication server are stored in the sending client system 100, and when the sending client system 100 clicks the telephone connection indication, the calling side is displayed. It is a server apparatus which provides the client system 100 with the URL and LN of a call setup communication server. The call setup communication server 210 is a server system that sets up a temporary DN number to be assigned to the sending client system 100, sets up a call between the exchange 250 and the sending client system 100, and proceeds with the call. . The call setup server 250 is composed of a general server system having a memory and a plurality of operation control devices, and is connected to the sending client system 100 through the Internet network.

In the embodiment of FIG. 1, the call setup server 250 has been described as being configured as a call setup web server 200 and a call setup communication server 210. However, the call setup server 250 may be configured as one server according to various hardware configurations. Of course, it can be comprised by the above server apparatus.

The call setup communication server 210 communicates with the call setup web server 200 and the IP based telephone exchange 300. The call setup communication server 210 communicates with the user agent and relays the communication with the IP-based telephone exchange network. In general, the communication between the call setup communication server 210 and the user agent based on the authorized IP, the call setup communication server 210 and the IP-based telephone exchange 300 is a private IP or authorized IP-based communication. In the present invention, the call setup communication server 210 automatically assigns the DN upon connection, so that the sender client system 100 does not need to log in in advance in order to use the service.

The user agent itself cannot make a call with the receiving telephone 600 which is directly / indirectly connected to the IP-based telephone exchange 300. The reason is that the IP-based telephone exchange 300 to recognize the IP-based telephone exchange 300, which must connect the call to each other, is connected to the receiver telephone 600 having the LN and the sending client system. This is because the connection information cannot be understood unless the user agent uses a possible DN. Accordingly, the call setup communication server 210 selects a temporary telephone identifier (DN) for which the IP-based telephone exchange 300 can recognize the sending client system 100, and makes a call to the IP-based telephone exchange 300. If requested, the IP-based telephone exchange 300 may perform a function of connecting a call between the telephone identifier DN used by the transmitting client system 100 and the receiving telephone identifier LN. In other words, the user agent assigned the temporary telephone identifier DN is operated with the same function as the virtual service provider internal telephone.

The exchange 350 is a device for switching the sending client system 100 and the receiving telephone 600. Switch 350 is an IP-based telephone exchange 300 operating on a packet network, a general telephone switch 500 and an IP-based telephone exchange 300 operating in a switched circuit network (Switched Circuit Network) And a gateway 400 which serves to connect signals between the general telephone exchange 500 and the general telephone switch 500.

The receiver side phone 600 is used as a generic term for a general phone connected to a general telephone exchange 500, a VoIP phone and a VoIP soft phone connected to an IP-based telephone exchange.

IP-based telephone exchange 300 is a telephone exchange based on the Internet protocol, a device that performs the same function as the existing telephone exchange based on the IP (Internet Protocol). It is a device that mainly manages call processing, signaling and dial plans, and manages functions provided by the telephone. IP-based telephone exchanges are commonly referred to as IP PBXs.

The phone 600 is a generic term for a phone attached to an IP-based telephone exchange 300 and a general telephone connected to a general telephone exchange 500 or a telephone capable of conducting a call. An example of the telephone 600 is an IP-based telephone. A software internet phone (also known as a VoIP soft phone) that installs a software module on a client computer and uses a headset with a microphone, or an internet phone (or 'VoIP') consisting of these software modules and phone hardware. Phone '), and a regular phone. The telephone 600 may be any type of telephone connected to the exchange 350.

The switch 350 has a variety of configurations depending on the type of the receiving telephone 600. For example, as shown in FIG. 1, when the receiving side phone 600 is composed of a general phone and an IP phone (a term used collectively as a VoIP phone and a soft VoIP phone), the exchange 350 is an IP-based telephone exchange 300. And a general telephone exchange 500, and a gateway 400 is provided between both exchanges. 2 and 4, when the receiving telephone 600 is configured with only a general phone, the switch 350 is composed of a gateway 400 and a general telephone switch 500 as shown in FIG. Alternatively, as shown in FIG. 4, the IP-based telephone exchange 300, the gateway 400, and the general telephone exchange 500 may be configured.

The call setup server 250 and the switch 350 may be formed as a communication line as shown in FIGS. 1 and 2, or may be formed as an internet network as shown in FIGS. 3 and 4. Switch 350 and receiving telephone 600 may be connected to a wired / wireless communication / call line as shown in FIGS. 1, 2 and 4 or may be connected to an internet network as shown in FIG. Of course.

In the present invention, the signaling of the voice call or the video call between the user agent and the receiving telephone is preferably using the SIP protocol, but is not necessarily limited thereto. Although the SIP protocol is an international protocol, Skype is known to use its own protocol instead of using the SIP protocol.

When the telephone connection indication is included in the body of the e-mail and provided to the sending client system 100, the sending client system 100 receives the call setup communication server 210 directly without receiving any information from the call setup web server 200. Call setup process is performed.

2 is a block diagram of an Internet phone call connection system according to another embodiment of the present invention. The difference between the system configuration of FIG. 2 and the system configuration of FIG. 1 is that FIG. 2 shows that the call setup server 210 is directly connected to a general telephone exchange 500 via the gateway 400 or directly without the gateway 400. When connected to the exchange 500. According to the service provider, when only the general telephone exchange 500 is used in the service provider's system without using the IP-based telephone exchange 300, the connection is used as shown in FIG.

The connection between the call setup communication server 210 and the gateway 400 generally uses the SIP protocol, and between the gateway 400 and the public switched telephone 500 is a telephone used in a switched circuit network. Use the connection method. The method of using the call setup communication server 210 directly connected to the general telephone exchange 500 without using the gateway 400 is generally not used, but the gateway 400 is connected to the call setup communication server 210. If a function is included, it can be applied.

3 is a block diagram of an Internet phone call connection system according to another embodiment of the present invention. The system configuration of FIG. 3 provides the service when the receiving telephone is subscribed to the service provider's VoIP phone service and does not have an IP-based exchange 300 or a general telephone exchange 400 in the service provider system. It is about a method.

The IP-based exchange 300 refers to an IP-based exchange 300 operated by a communication service provider and the receiving telephone 600 is a VoIP telephone 600 used by a service provider. Therefore, the IP-based telephone exchange 300 and the receiving telephone 600 of the communication service provider are mostly connected to the Internet and may be connected to a dedicated line.

4 is a block diagram of an Internet phone call connection system according to another embodiment of the present invention. 3 is different from FIG. 3 when the receiving telephone is subscribed to the general telephone service of the telecommunications operator, and the service provider system is not provided with the IP-based telephone exchange 300 or the general telephone exchange 400. It's about how.

The IP-based telephone exchange 300 refers to an IP-based exchange 300 operated by a telecommunication service provider, the gateway 400 connecting the IP-based telephone exchange 300 and the general telephone exchange 500, and the general telephone exchange 500 The receiving side telephone 600 connected to) is a regular telephone. It is also technically possible to connect the call setup communication server 210 and the gateway 400 or the general telephone switch 500 directly. However, in most cases, when a telecommunication company uses a data communication connection with the outside, it is common to make it interoperate with the IP-based telephone exchange 300.

The call setup server 250 shown in FIGS. 1 to 4 may configure the call setup web server 200 and the call setup communication server 210 as a service provider internal system or an external third party system. Of course. The transmitting client system 100 and the call setup communication server 210 may be connected to each other by a public IP address, but may be connected to a private IP when the user is connected by a dedicated line or inside the service provider system. The call setup communication server 210 and the IP-based telephone exchange 300 or the general telephone switch 400 may be implemented in any manner on the basis of an authorized IP or a private IP.

In the embodiments shown in FIGS. 1 to 4, further modifications may be made in connection with the issue of the DN, which is a temporary number used in the user system 100. In the drawings and corresponding descriptions shown in FIGS. 1 to 4, it is described that the DN is allocated in the call setup communication server 210, but the DN number issuing logic may be combined into other parts or may be separately configured. For example, a temporary DN is issued to the sender client system 100 to the call setup web server 200, the IP-based telephone exchange 300, the general telephone exchange 500, or a third system interworking with the service provider system. Of course, logic can be implemented.

5 is a flowchart illustrating a call connection using the Internet phone call connection system according to an embodiment of the present invention. In the connection flow diagram of FIG. 5, the call setup server 250 is divided based on the call setup web server 200 and the call setup communication server 210, and the call setup server 250 is one integrated server. In the case of consisting of only the difference flow will be described.

Step 501 is a step in which the sending client system 100 accesses the call setup web server 200 through a web browser. That is, the call setup web server 200 displays the telephone connection indication including the URL information and the LN information of the call setup communication server 210 through the web browser of the client system 100. Telephone connection indicators can be displayed via e-mail in addition to the web browser. The telephone connection indication may be provided in various ways, such as in the form of text, an image, or a link. 6 is an example of a telephone connection indication displayed to the sending client via a web browser and a telephone connection indication displayed to the sending client via an e-mail. FIG. 6 (a) shows the telephony indications 601 and 603 provided in the form of images and text, respectively. FIG. 6 (b) shows an example of the telephony indication 605 provided in the form of images. Although the telephone connection indication shown in FIG. 6 does not appear to include URL and LN information of the call setup communication server 210 in appearance, the telephone connection indication is accompanied by an execution statement executed when the telephone connection indication is clicked as meta information. The call setup communication server 210 includes the URL and the LN information.

Step 503 is a step in which the connected sender client system 100 clicks on the telephone connection indication that the client wants to talk to. The moment the client clicks on the telephone connection indication, the call setup web server 200 transmits the URL information and the LN information of the call setup communication server 210 to the sending client system 100.

In step 505, after the web browser of the sending client system accesses the web server function existing in the call setup communication server 210 using the URL information of the call setup communication server 210, This means that the index.html stored in the order of the job to connect to the communication server 210 is downloaded. Typically, a single server system includes a variety of functional logic. The call setup communication server 210 also includes logic for providing a web server function (which provides information when a web browser is connected).

There is usually a flash-related tag in index.html. Step 507 is a port of a web server function that uses a port 8080 in the call setup communication server 210 when the web browser of the sending client system recognizes the tag. You can download the user agent that will make calls. In the embodiment of the present invention, since the call function is implemented using the flash function, the client does not need to download a separate program in the case of a transmitting client system equipped with a flash player. That is, the call setup communication server 210 temporarily uses a web server function using the 8080 port in the call setup communication server 210 to sender client system to a user agent (hereinafter referred to as 'flash phone'). It is to provide a user agent that performs call function by accessing the port.

Step 509 is a step in which the flash phone automatically downloaded to the sending client system is automatically connected to the flash server and the flash application existing inside the call setup communication server 210.

Step 511 is a procedure in which a DN is assigned while the flash phone performs an automatic login function. In other words, when the flash phone attempts to log in (which means accessing the flash application), the flash application inside the call setup communication server 210 receives from a SIP server having a logic function of assigning a DN number used by the user system. Attempt login by assigning DN number. In the case of Skype or Natephone, a user enters an ID and a password before making a phone call, but in the present invention, a client system user does not need to enter a separate login and password. Accordingly, the client system can make a call even if the client system is not a member of the Internet phone call connection system of the present invention.

However, the logic for assigning the DN number allocated by the SIP server may be easily configured to be performed by the call setup web server 200, another logic part in the call setup communication server, or a third independent server according to the needs of use.

Step 513 is a procedure to check if the connecting flash phone has the LN number to be connected. Step 515 is to check the LN number and make a telephone call. Step 517 is a procedure for checking whether a call is connected. Step 519 is a step in which the call ends first in the DN after the phone call between the LN and the DN. Step 521 is a telephone call between LN and DN, and then the call is terminated at LN first. Step 523 is a procedure for displaying an end screen to the client when the flash phone call is terminated, and Step 525 is a procedure for providing a standby screen for requesting the LN number input to the client system.

In the above-mentioned steps, in the case of Step 525, after the process of Step 523, the sender client system 100 presses a Reset button or the like and attempts to input new LN information. In this case, if the call setup web server 200 inputs the counterpart LN information to be called and clicks the call button, the procedure proceeds from Step 513 shown in FIG. This is because the client system 100 is connected to the call setup communication server 210 and the DN number is already assigned, so there is no need to perform the steps 505, 507, step 509 and step 511 again.

As another additional example, a more modified embodiment will be described. The Internet phone call connection system according to the present invention does not provide a call connection indication and the call setup server 250 allows the sending client system to provide a web site and input counterpart LN information to be called. 7 is an example of a web page that is provided from the call setup server to the sending client system and enters LN information after visiting a web site. If the client enters LN information (eg vicwave-0126) and clicks the call button, the procedure proceeds from Step 505 shown in FIG.

If the call setup server 250 is provided as one call setup server 250 in which two functions are integrated without being separated into the call setup web server 200 and the call setup communication server 210, the steps 503 to 505 may be performed. It should proceed directly to Step 507 without going through. This is because when the sending client system 100 connects to the call setup server 250 through the web browser, there is no need to transmit URL information of the corresponding server. In addition, only the LN information is included in the telephone connection indication, and it is not necessary to include the URL information of the call setup server 250. In step 503, the client proceeds to step 507 without passing through step 505 at the moment the client clicks the telephone connection indication.

Even if the call setup server 250 is not divided into the call setup web server 200 and the call setup communication server 210 and is provided as one call setup server 250 in which two functions are integrated, the call connection indication is displayed. When displayed via e-mail, if the client clicks on the telephone connection indication, step 501 described in FIG. 5 is performed.

8 is a call setup and call connection flowchart of the Internet phone call connection system according to the present invention. FIG. 8 illustrates a call setup and call connection flow based on the Internet phone call connection system shown in FIG. 1. The call setup step ⓐ, which is the most important feature of the present invention, will be described. The call setup step ⓐ in FIG. 8 is a flowchart for describing Step 509, Step 511, and Step 515 in detail in FIG. 5. When the user agent of the sending client system 100 is open with the call setup server 250, the flash application of the call setup server 250 is assigned a temporary DN to be assigned to the sending client system 100 on the SIP server. Request (Get User ID), the SIP server grants a temporary DN to the flash application (User Id). After that, the client server logs in to the SIP server (REGISTER) and sends a confirmation (200 OK) to the register request. Among the above steps, the Register step and the 200 OK step are common steps in all SIP communication.

Next, the sending client 100 user agent requests a call corresponding to the LN to the flash application (call), and the flash application invites the receiving telephone 600 through the SIP server and the IP-based telephone exchange 300. Complete the call setup step (ⓐ) through the invite and ringing steps. Then, the invite is transmitted to the SIP server in the form of invite LN number (invite to LN).

In the call proceeding step (ⓒ), the user agent and the flash application of the sending client system 100 proceed in a net stream manner, and the flash application and the receiving phone 600 are connected to an altipi stream. In a way. In the call proceeding step (ⓒ), the flash application and the receiving phone 600 are generally directly connected to the Internet and proceed in packet communication, but packet communication may be performed through the IP-based telephone exchange 300. . In the call termination step ⓓ, all devices are notified that the call has ended.

9 is a detailed configuration diagram and DN assignment flowchart of the sending client system and the call setup server. If the user agent and the call setup server of the sender client system according to the present invention are implemented using flash, the call setup server will be described with a flash application and a SIP server as shown in FIG. A flash server is further provided. In FIG. 8, the flash server is omitted for convenience of description.

The transmitting client system 100 is provided with a user agent (hereinafter referred to as "flash phone" when implemented in flash), and the call setup server 250 is provided with a flash server, a flash application, and a SIP server. More preferably, the flash server, the flash application, and the SIP server may be provided in the call setup communication server 210 among the call setup servers. When the user agent connects to the flash server (ST1), the flash server forwards it to the flash application. The flash application requests a DN from the SIP server (ST2), and the SIP server transmits the DN to the flash application (ST3). At this time, the SIP server should be provided with a pre-stored DN available in the exchange 350 in the memory. Alternatively, when the SIP server receives the ST2 step request, the SIP server may request a DN available to the exchange 350 or a third server, and transmit the DN received from the exchange or the third server to the SIP server. have. After that, the SIP server logs in the client to complete the provisioning of the temporary DN. Next, the transmitting client system 100 transmits an LN while requesting a call (ST4). The flash server sends the call request and the LN information to the flash application, and the flash application requests the SIP server to invite the corresponding LN (ST5), and invites the SIP server to the exchange 350 for the corresponding LN. (ST6).

As described in FIG. 9, the call setup server 250 automatically grants the DN assigned to the corresponding flash application to be used by the user agent even if there is no client request, and the assigned DN is not delivered to the user agent. have. The assigned DN is stored in the flash application, and the flash application and the user agent maintain the connection through the flash server. Since the connection configuration is a method commonly used in the implementation of a game program implemented as a flash program, a detailed description thereof will be omitted.

Although specific embodiments of the present invention have been described and illustrated above, it will be apparent that various modifications may be made by those skilled in the art without departing from the technical spirit of the present invention. Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should fall within the claims appended to the present invention. In the present invention, the description has been made mainly on the voice call, but it can be easily applied to the video call. In this case, the receiving telephone 600 refers to a video phone, and should use a protocol suitable for video instead of the SIP protocol.
