It is a detailed block diagram of a transmission side client system and a call setup server, and a DN addition flowchart.

  First, terms used in the present invention are defined. The sender client identifier is an identifier for identifying a sender who made a call that can be recognized by the exchange. In the present invention, the sender client identifier is called a DN (Dial Number). The receiving side telephone identifier is an identifier for identifying the receiving side telephone that receives the telephone that can be recognized by the exchange, and in the present invention, this is called an LN (Location Number).

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram showing an internet telephone call connection system according to an embodiment of the present invention. The Internet telephone call connection system includes a transmission side client system 100, a call setup server 250, an exchange 350 and a reception side telephone 600.

  The sending client system 100 is a system that receives call setup server URL (Uniform Resource Locator) information and a receiving phone identification number from the call setup server 250 and makes a call with the receiving phone 600 via the exchange 350. The sending-side client system 100 has a hardware configuration such as a personal computer or notebook computer provided with a general input / output device, a mobile phone, or an electronic device connected via the Internet. The sending-side client system 100 connects to a web browser that analyzes and shows HTML (Hyper Text Markup Language) and a call setup server 250 to set up a call, and connects to a packet network to make a voice or video call of a VoIP softphone. A user agent.

  The user agent is a software module that is temporarily or permanently provided in the memory of the transmission client system during call setup or in progress, and is a module that can be realized by software called flash. That is, a service can be realized using flash software which is a general general-purpose program. In this case, the call setup communication server 210 is provided with a flash application, and performs most call setup operations such as assigning a DN number that can be used in the exchange 350 instead of the user agent. Therefore, a simple user agent in charge of only the function of the flash phone in conjunction with the flash agent is temporarily installed in the sending-side client system 100 only when the user does not take any special action during a call. Can be.

  When the sender clicks the telephone icon or button (phone connection display) displayed on the web browser, the user agent receives the URL information of the call setup server 250 and then connects to the call setup server 250 to make a call. Is a module that performs a series of processes such as making a call with the receiving telephone 600 connected to the exchange 350, and suspending 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 a telephone connection display in which the URL and LN of the call setup communication server 210 are stored on the transmission client system 100, and when the transmission client system 100 clicks the telephone connection display, the transmission client This is a server device that provides the URL and LN of the call setup communication server 210 to the system 100. The call setup communication server 210 is a server system that sets a temporary DN number assigned to the sending client system 100, sets up a call between the exchange 350 and the sending client system 100, and advances the call. The call setup server 250 is composed of a normal server system having a memory and a large number of arithmetic and control units, and is connected to the transmission-side client system 100 via the Internet network.

  In the embodiment of FIG. 1, the call setup server 250 is described as including the call setup web server 200 and the call setup communication server 210. However, the call setup server 250 may be configured as a single server according to various hardware configurations. You may comprise with three or more server apparatuses.

  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 it to connect the communication with the IP-based telephone exchange network. In general, the call setup communication server 210 and the user agent communicate with each other on an authorized IP basis, and the call setup communication server 210 and the IP basis telephone exchange 300 perform private IP or authorized IP basis communication. According to the present invention, the call setup communication server 210 that automatically assigns a DN at the time of connection eliminates the need to go through a login process in advance in order to use this service in the sending client system 100.

  The user agent itself cannot make a call with the receiving telephone 600 that is directly / indirectly connected to the IP-based telephone exchange 300. The reason is that the IP-based telephone exchange 300 can recognize and connect to the receiver telephone 600 having the LN and the transmitting-side client system 100 in order to connect the IP-based telephone exchange 300 for which calls must be connected to each other. This is because the connection information cannot be understood unless the user agent uses such a DN. Accordingly, the call setup communication server 210 selects the temporary telephone identifier DN that allows the IP base telephone exchange 300 to recognize the transmitting client system 100 and requests the IP base telephone exchange 300 to make a call. A function for connecting a call between the telephone identifier DN used by the client system 100 on the receiving side and the telephone identifier LN on the receiving side can be performed. That is, the user agent to which the temporary telephone identifier DN is assigned operates with the same function as the internal telephone of the virtual service provider.

  The exchange 350 is a device that switches between the transmission-side client system 100 and the reception-side telephone 600. The exchange 350 includes an IP-based telephone exchange 300 that operates on a packet network basis, a general telephone exchange 500 that operates on a switch circuit-based network (Switched Circuit Network), and the IP-based telephone exchange 300 and the general telephone exchange 500. It is comprised with the gateway (Gateway) 400 which has the function to connect a signal.

  The receiving-side telephone 600 is used as a term for a general telephone connected to the general telephone exchange 500, a VoIP telephone (VoIP phone) and a VoIP softphone connected to the IP-based telephone exchange 300.

  The IP-based telephone exchange 300 is a telephone exchange based on the Internet protocol, and is a device that performs the same functions as those known as existing telephone exchanges on an IP (Internet Protocol) basis. It is a device that mainly manages call processing, signaling, and dial plan, and manages functions provided by a telephone. Normally, the IP-based telephone exchange 300 is called IP PBX.

  The receiving-side telephone 600 is a term that generally refers to a telephone that is attached to the IP-based telephone exchange 300 and can make a call, or a general telephone that is connected to the general telephone switching system 500. As an example of the receiving-side telephone 600, an IP-based client computer A software internet phone (or also called “VoIP softphone”) that makes a call using a headset with a microphone attached to the microphone, and an internet phone (such as a “VoIP softphone”) composed of such a software module and phone hardware ( Alternatively, it may be a “VoIP phone”) and a general telephone. The receiving side telephone 600 may be any kind of telephone connected to the exchange 350.

  The configuration of the exchange 350 has various configurations depending on the type of the receiving side telephone 600. For example, as shown in FIG. 1, when the receiving side telephone 600 is configured by a general telephone and an IP telephone (used as a general term for a VoIP telephone and a VoIP softphone), the exchange 350 is generally similar to the IP-based telephone exchange 300. A telephone exchange 500 is provided, and a gateway 400 is provided between the two exchanges. 2 and 4, when the receiving side telephone 600 is configured only by a general telephone, the switch 350 may be configured by a gateway 400 and a general telephone switch 500 as shown in FIG. As shown in FIG. 4, the IP telephone exchange 300, the gateway 400, and the general telephone exchange 500 may be used.

  The call setup server 250 and the exchange 350 may be formed by communication lines as shown in FIGS. 1 and 2, or may be formed by the Internet network as shown in FIGS. The exchange 350 and the receiving telephone 600 may be connected via a wired / wireless communication / call line as shown in FIGS. 1, 2 and 4, or may be connected via an Internet network as shown in FIG. Of course, you may.

  In the present invention, it is preferable to use the SIP protocol for the voice call or video call signaling between the user agent and the receiving side telephone 600, but this is not necessarily limited to this. Although the SIP protocol is an international standard, it is known that the “Skype” company does not use the SIP protocol but uses a modified 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 does not receive any information from the call setup web server 200 and directly receives the call setup communication server 210. And a call setup process is performed.

  FIG. 2 is a block diagram showing an Internet telephone call connection system according to another embodiment of the present invention. 2 is different from the system configuration of FIG. 1 in that the call setup server 250 is connected to the general telephone exchange 500 via the gateway 400 or directly to the general telephone exchange 500 without going through the gateway 400. Is connected to. Some service providers do not use the IP-based telephone exchange 300 but connect only the general telephone exchange 500 in the service provider system as shown in FIG.

  The connection between the call setup communication server 210 and the gateway 400 generally uses the SIP protocol, and the gateway 400 and the general telephone exchange 500 use a telephone connection method used in a switched circuit network. A method of connecting the call setup communication server 210 directly to the general telephone exchange 500 without using the gateway 400 and using the call setup communication server 210 is not generally used. However, when the call setup communication server 210 includes the gateway 400 function. Is applicable.

  FIG. 3 is a block diagram showing an Internet telephone call connection system according to still another embodiment of the present invention. In the system configuration of FIG. 3, the receiving telephone 600 is subscribed to the VoIP telephone service of the communication carrier, and this service is provided when the IP provider telephone exchange 300 or the general telephone exchange 500 is not included in the service provider system. Relates to the method of providing.

  The IP base exchange 300 means the IP base exchange 300 operated by the communication carrier, and the receiving side telephone 600 is a VoIP telephone used by the service provider. Therefore, the IP carrier telephone exchange 300 of the communication carrier and the receiving side telephone 600 are mostly connected by the Internet, and may be connected by a dedicated line.

  FIG. 4 is a block diagram showing an Internet telephone call connection system according to still another embodiment of the present invention. The difference from FIG. 3 is that when the receiving side telephone 600 is subscribed to the general telephone service of the communication carrier and the IP provider telephone exchange 300 or the general telephone exchange 500 is not provided in the service provider system, It relates to a method of providing a service.

  The IP-based telephone exchange 300 means an IP-based telephone exchange operated by a telecommunications carrier, and includes a gateway 400 that connects the IP-based telephone exchange 300 and the general telephone exchange 500, and a receiving-side telephone 600 that is connected to the general telephone exchange 500. Is a general telephone. It is technically possible to directly connect the call setup communication server 210 and the gateway 400 or the general telephone exchange 500. However, in most cases, the communication company generally works with the IP-based telephone exchange 300 when it is used for data communication connection with the outside.

  The call setup server 250 presented in FIG. 1 to FIG. 4 may be configured by the service setup internal system of the call setup web server 200 and the call setup communication server 210, or realized in the form of an external third party system. Of course, you may do. The sending-side client system 100 and the call setup communication server 210 are connected to each other by an authorized IP address, but are connected by a private IP when the user is connected by a dedicated line or inside the service provider system. You can also. The call setup communication server 210 and the IP-based telephone exchange 300 or the general telephone exchange 500 can be realized by any system using a certified IP base or a private IP base.

  In the embodiment shown in FIGS. 1 to 4, it goes without saying that additional modifications are possible in connection with the issuance of DN, which is a temporary number used in the transmitting client system 100. 1 to 4 and the corresponding description, it is described that the DN is assigned by the call setup communication server 210. However, the DN number issuing logic can be adapted to other parts or can be separately configured. It is. For example, the logic for issuing the temporary DN to the sending client system 100 can be realized in the call setup web server 200, the IP-based telephone exchange 300, the general telephone exchange 500, or a third system linked with the service provider system. It is.

  FIG. 5 is a flowchart of call connection using the Internet telephone call connection system according to an embodiment of the present invention. The connection flowchart of FIG. 5 will be described based on the case where the call setup server 250 is separated into the call setup web server 200 and the call setup communication server 210. In the case where the call setup server 250 is configured as one integrated server. Describes only the flow with differences.

  Step 501 is a step in which the sending client system 100 connects to the call setup web server 200 through a web browser. That is, the call setup web server 200 displays a telephone connection display including the URL information and LN information of the call setup communication server 210 through the web browser of the transmitting client system 100. Of course, the telephone connection display can be displayed not only via a web browser but also via e-mail. The telephone connection indication may be provided in various ways such as a text form, an image form, or a link sentence. FIG. 6 is an example of a telephone connection display displayed on the sending client via a web browser and a telephone connection display displayed on the sending client via e-mail. FIG. 6A shows telephone connection displays 601 and 603 provided in the form of an image and text, respectively, and FIG. 6B shows an example of the telephone connection display 605 provided in an image form. The telephone connection display shown in FIG. 6 does not appear to include the URL and LN information of the call setup communication server 210 in appearance, but is executed when the telephone connection display is clicked as meta information in the corresponding telephone connection display. The URL and LN information of the call setup communication server 210 are included together with the executable statement.

  Step 503 is a step in which the client clicks a telephone connection display that the client desires to call in the connected sending client system 100. The moment the client clicks the telephone connection display, the call setup web server 200 transmits the URL information and 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 100 connects to the web server function existing in the call setup communication server 210 using the URL information of the call setup communication server 210, the sending client system 100 calls the call setup communication. This means that index.html storing the order of jobs (jobs) connected to the server 210 is downloaded. Normally, various function logics are included in one server system, but logic that provides a web server function (providing information when a web browser connects) is also provided in the call setup communication server 210. include.

  Normally, a flash related tag (tag) exists in index.html, but in step 507, the web browser of the sending client system 100 recognizes the tag and uses the 8080 port in the call setup communication server 210. Download the user agent that connects to the server function port and performs the call function. In the embodiment of the present invention, since the telephone function is implemented using the flash function, in the case of the transmitting client system 100 provided with the flash player, the client does not need to download a separate program. In other words, the call setup communication server 210 is temporarily connected to the client system 100 on the transmission side through a user agent (hereinafter referred to as “flash phone”) port using a web server function using the 8080 port in the call setup communication server 210. Provide a user agent that performs call functions.

  Step 509 is a step in which the flashphone automatically downloaded to the sending client system 100 is automatically connected to the flash server and the flash application existing in the call setup communication server 210.

  Step 511 is a stage in which DN is given while the flashphone performs the automatic login function. In other words, if the flashphone attempts to log in (meaning that it accesses the flash application), the flash application in the call setup communication server 210 can be accessed from the SIP server having a logic function for assigning a DN number used by the user system. A DN number is assigned and login is attempted. In the case of Skype or Natephone, the user logs in by entering an ID and password before making a call, but the present invention means that the client system user does not need to enter a separate login and password. Accordingly, the sending client system 100 can make a call even if it is not registered as a member of the Internet telephone call connection system of the present invention.

  However, the DN number allocation logic allocated by the SIP server can be easily performed by the call setup web server 200, another logic part in the call setup communication server 210, or a third independent server, as required for use. Can be configured.

  Step 513 is a step of confirming whether or not the flashphone to be connected has the LN number desired to be connected. Step 515 is a step of confirming the LN number and connecting the telephone. Step 517 is a step of confirming whether or not a telephone is connected. Step 519 is a stage in which a telephone call is first terminated by DN after a telephone call is made between LN and DN. Step 521 is a stage in which after a telephone call is made between the LN and the DN, the call is ended first by the LN. Step 523 is a step of displaying an end screen on the client when the flashphone call is finished, and step 525 is a step of providing a standby screen for requesting the sending client system 100 to input the LN number.

  In the above-described stage, step 525 is a case where the process proceeds to step 523 and then the transmission side client system 100 presses a reset button or the like to input new LN information. In this case, if the other party LN information to be called by the call setup web server 200 is input and the call button is clicked, the procedure starts from step 513 presented in FIG. This is because the sending client system 100 is connected to the call setup communication server 210 and has already been assigned a DN number, so that the steps 505, 507, 509 and 511 need not be performed again.

  As another example, a more modified embodiment will be described. The Internet telephone call connection system according to the present invention does not provide a telephone connection display, and the call setup server 250 provides a website to the sending client system 100 and inputs the partner LN information to be called. FIG. 7 is an example of a web page that is provided from the call setup server 250 to the sending client system 100 and enters LN information after visiting a website. If the client inputs LN information (for example, vicwave-0126) and clicks the call button, the procedure is performed from step 505 presented in FIG.

  If the call setup server 250 is not separated into the call setup web server 200 and the call setup communication server 210 and is provided by a single call setup server 250 in which two functions are integrated, the steps 503 to 505 are not performed immediately. Proceed to step 507. This is because if the sending client system 100 connects to the call setup server 250 through a web browser, it is not necessary to transmit the URL information of the corresponding server. Further, only the LN information is included in the telephone connection display, and it is not necessary to include the URL information of the call setup server 250. In step 503, the moment the client clicks the telephone connection display, the process proceeds to step 507 without going through step 505.

  Even if the call setup server 250 is not separated into the call setup web server 200 and the call setup communication server 210 and is provided with a single call setup server 250 in which two functions are integrated, the telephone connection display is made via e-mail. If displayed, if the client clicks the telephone connection display, step 501 described with reference to FIG. 5 is performed.

  FIG. 8 is a flowchart of call setup and call connection of the Internet telephone call connection system according to the present invention. FIG. 8 shows a flow of call setup and call connection based on the call connection system of the Internet telephone shown in FIG. The call setup stage (a), which is the most important feature of the present invention, will be described. The call setup stage (a) in FIG. 8 is a flowchart for explaining step 509, step 511 and step 515 in FIG. 5 in detail. If the user agent of the sending client system 100 is connected to the call setup server 250 (open), the flash application (Flash APP) of the call setup server 250 is temporarily allocated to the sending client system 100 to the SIP server (SIP Server). Requesting a DN (Get User ID), the SIP server grants a temporary DN to the flash application (User ID). Thereafter, the sending client system 100 is logged into the SIP server (REGISTER), and a confirmation for the register request is sent (200 OK). Of the above steps, the Register step and the 200 OK step are common steps in all SIP communications.

  Next, the user agent of the sending client system 100 requests a call corresponding to LN (Call) from the flash application, and the flash application invites the receiving phone 600 through the SIP server and the IP-based telephone exchange 300. The call setup stage (a) is completed through the ringing stage. Then, it is transmitted to the SIP server in the form of an invite LN number (invite for the LN) in the invite.

  In the call progress stage (c), the user agent and the flash application of the sending client system 100 are performed by the net stream method, and between the flash application and the receiving phone 600 are performed by the RTP stream (rtp stream) method. Is called. In the call progress stage (c), the flash application and the receiving phone 600 are generally connected directly on the Internet and performed by packet communication. However, it is possible that the packet communication can proceed through the IP-based telephone exchange 300. Of course. In the call end stage (d), all devices are notified of the end of the call.

  FIG. 9 is a detailed configuration diagram and a DN assignment flowchart of the transmission side client system and the call setup server. If the user agent of the sending client system 100 and the call setup server 250 according to the present invention are implemented using flash, the call setup server 250 is described as having a flash application and a SIP server in FIG. As shown in FIG. 9, a flash server is further provided. In FIG. 8, for convenience of explanation, the flash server is omitted.

  The sending client system 100 is provided with a user agent (when implemented in flash, this is referred to as “flash phone”), 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 are included in the call setup communication server 210 of the call setup server 250. If the user agent connects to the flash server (ST1), the flash server transmits this 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 must be prestored in the memory with a DN that can be used in the exchange 350. Alternatively, when the SIP server receives the request in ST2, the SIP server requests a usable DN from the exchange 350 or the third server, and transmits the DN received from the exchange 350 or the third server to the SIP server. You can also go to the stage. Thereafter, the SIP server logs in the corresponding client to complete the automatic provision of the temporary DN. Next, the transmitting client system 100 requests Call and transmits LN (ST4). The flash server transmits 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 the SIP server invites the exchange 350 to the corresponding LN (ST6).

  As described with reference to FIG. 9, the DN that is assigned to the flash application and used by the user agent is automatically given by the call setup server 250 even if there is no client request, and the assigned DN is not transmitted to the user agent. I understand that. The granted DN is stored in the flash application, and the flash application and the user agent maintain a connection through the flash server. Since such a connection configuration is a method that is universally used in realizing a game program or the like realized by a flash program, detailed description thereof is omitted.

  Although specific embodiments of the present invention have been described and illustrated above, it is obvious that various modifications may be made by those skilled in the art without departing from the technical idea of the present invention. Such modified embodiments should not be individually understood from the spirit and scope of the present invention, and can be said to fall within the scope of the claims attached to the present invention. Although the present invention has been described mainly with respect to voice calls, it can be easily applied to video calls. In this case, the receiving telephone 600 indicates a video phone, and a protocol adapted to the video should be used instead of the SIP protocol.
