Method for automatic call connection through web in intelligent network-internet interworking structure {Method for click to call service from WWW based on PSTN / IN-internet interworking architecture}

The present invention relates to an automatic telephone connection method through the web in an intelligent network-internet interworking structure, and more particularly, to an intelligent network-internet interworking (PSTN / IN-Internet InTerworking: PINT) service server system. The present invention relates to an automatic telephone connection method through the web in an intelligent network-internet interworking structure that allows a user to request a telephone connection to a telephone network through the Internet by introducing a service client system for providing automatic telephone connection service to the Internet network. .

Nowadays, Internet users are very common, and internet users can easily get a lot of information through the web. In particular, by searching for information or searching a phone number through the web, a general user can easily obtain an e-mail address or a phone number for a specific person or a specific company. In the case of e-mail, it is generally possible to compose and send an e-mail directly through a web browser by simply clicking on the e-mail address specified on the web.

However, a phone call can be connected only when the user picks up the handset and dials the retrieved phone number directly. This is due to the current network structure, which separates telephone and Internet networks. As with sending e-mails, it would be very convenient for the user to be able to make or receive calls automatically by just clicking on the phone number specified on the web.

The automatic telephone connection service may be applied to a telephone number search service and an e-commerce service currently provided by a web service provider. Users can click on a searched address to see a map corresponding to the address, and click on an email address to automatically send an email. If the user can connect the phone with the desired counterpart simply by clicking on the searched phone number, the user will be able to provide convenience and increase the service utilization rate to the web service provider. Also, in the case of e-commerce service, if a user who looks up a product through the web wants to receive detailed information about the product through an agent, the user does not call the agent directly, but simply clicks the 'connect agent' icon specified on the web. You can have a call from the counselor. These features are currently being provided independently by using Voice over Internet Protocol (VoIP) technology in the existing Internet network. However, compared to the general telephone network, the limitation of voice call quality through VoIP network and each user's VoIP environment are established. Due to the limitation of the situation is not widely spread.

On the other hand, the intelligent network is a network that can provide a variety of additional services in addition to the general telephone service has a variety of call control functions. As shown in FIG. 1, the intelligent network structure includes a service management system 11 having a service management function, a service node system 12 having an intelligent network control function, a service exchange function, and an intelligent information providing function. The service node system 12 receives an intelligent network service request from the telephone subscriber 15 and provides a service.

The intelligent network plays a role in increasing the profitability of the telephone network by providing various additional services, but has limited the spread of the intelligent network service as its area is limited to the general telephone network. If the area of the intelligent network service is extended to the internet network through the intelligent network-internet interworking function, the intelligent network service will be further activated by expanding the existing intelligent network service and discovering a new intelligent network service.

In the existing Internet network, SIP (Session Initiation Protocol), an application layer control protocol, is used to perform functions such as creating, modifying, and terminating a multimedia session or call.

However, the existing Internet network has been started to be independently provided by using Voice over Internet Protocol (VoIP) technology. However, compared to the general telephone network, the limitation of voice call quality through VoIP network and each user should establish VoIP environment. Due to limitations, it is not widely spread, and the intelligent network plays a role in increasing the profits of the telephone network by providing various additional services, but there is a problem in that the intelligent network service has a limitation in that the area is limited to the general telephone network. .

The present invention has been made to solve the above problems and introduces an intelligent network-internet interworking (PINTN) service server system for interworking between an intelligent network and an internet network, and provides an automatic telephone connection service to the internet network. The purpose of the present invention is to provide an automatic telephone connection method that allows a user to request a telephone connection over the Internet by introducing a service client system.

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

2 is a view showing the basic configuration of the device constituting the present invention, the function of each device is as follows. The user PC is equipped with a web browser 21 and connected to the web service provider system 22 to perform a web search function and a window popup function for an automatic call connection request. The automatic telephone connection service client 23 is located in the web service provider system 23 and receives a telephone connection request from a web user, converts it into a PINT message on the Internet, and delivers it to the companion service server system 25. The web service provider is a service subscriber who subscribes to an automatic telephone connection service such as a telephone number search service provider and an e-commerce service provider, and provides the automatic telephone connection service to the user.

The automatic telephony service server 24 located on the interlocking service server system 25 receives a call request from the automatic telephony service client 23 as a PINT message on the Internet and sends it to an appropriate service node system 264 located in the telephone network. To pass.

The interworking service server system 25 is a system located in the internet network for providing an intelligent network-internet interworking service. The interworking service server system 25 manages and provides various interlocking services such as an internet call waiting service in addition to an automatic telephone connection service. Accordingly, the interlocking service server system 25 receives a service request from a plurality of interlocking service clients, authenticates the service client, and provides a function of distributing the service to an appropriate service node system according to the type of service. The service node system 26 provides a function of connecting two telephone numbers by dialing each telephone number upon receiving a PINT message requesting a telephone connection from the automatic telephone connection service server 24. In addition, the service node system 26 may be distributed for each service provided.

3 is a flowchart illustrating a method for providing automatic telephone connection service according to the present invention. When a user who is searching for a web using a PC equipped with a web browser wants to receive an automatic telephone connection service, the user clicks a phone number on the web (S31). The web browser then opens a window for an automatic call connection request on the screen on the user PC (S32). The user inputs a user's telephone number (b) that he / she wants to answer, and sets a time for making a telephone connection (S33). Here, automatic dial-up may be specified to be performed immediately or at a scheduled time.

The web browser on the user PC sends the inputted telephone request to the automatic telephone connection service client on the web service providing system, and the automatic telephone connection service client converts the telephone connection request into a PINT message and transmits it to the automatic telephone connection service server. The automatic telephony service server authenticates the request from the client and sends it to the service node system that will provide the received PINT message service. Upon receiving the PINT message, the service node system generates call processing data and a process (S34). It is determined whether the telephone connection request is an immediate connection or a reserved connection (S35).

As a result of the determination in step S35, if the switch connection request is an immediate connection, an outbound setting for each telephone number is immediately executed. In the case of a reserved connection, the reservation time is recorded in the call processing data block and monitored at a predetermined time. When the reservation time comes, the call setup is executed to connect the two requested telephone numbers (a) and (b) (S36, S37). The service node system converts the automatic telephone connection result into a PINT message and notifies the user through the automatic telephone connection service server and the client (S39).

Meanwhile, the user may cancel the request after requesting an automatic telephone connection and before the call is connected. When the user cancels the telephone connection, the service client converts the cancellation request into a PINT message and sends it to the service server. The service server receives the message and delivers the message to the service node system. The service node system releases the call for the connected phone, cancels the reservation for the reserved phone, and transmits the result to the service client through the service server.

Automatic telephony services also support multiparty calls over multiple call connections. The user can request a conference call by clicking on one icon linked to several phone numbers through a web browser. The multi-party call request is sent to the service node system via the service client and server, and the service node system connects the telephones to the requested number of telephone numbers.

4 is a diagram illustrating the function of a service server system. When the service server system receives the telephone connection request from the service client system (S41), the service server system authenticates whether the telephone connection request is a request from a subscribed web service provider (S42). If the request is not authenticated, the telephone connection request is rejected (S43). If the request is authenticated, the requested PINT message is analyzed to recognize the type of the telephone connection service and the telephone service is requested to the appropriate service node system (S44, S45). ).

The automatic telephone connection service may charge the user who requested the service or charge a phone number specified on the web. For example, a telephone number search service is generally based on user billing, and an agent connection service may charge a user or a telephone number specified on the web, that is, an agent.

5 shows a call processing flow of a service node system for charging when the automatic telephone connection service is applied to user charging. This figure shows the process A in FIG. 3 in detail. If the user requests an automatic telephone connection between the retrieved telephone number (a) and the user telephone number (b), the telephone fee is charged to the user telephone number (b). Therefore, when a user accidentally or maliciously designates a third party's telephone number rather than the user's own number, a telephone fee may be charged to the third party.

In order to prevent this case, the service node system first calls the user's telephone number (b) and checks whether the user requests the service through voice guidance (S51-S53).

At this time, if it is determined in step S53 that the correct user, the call to the phone number on the web (a), and the phone number (a) and the automatic telephone connection between the user phone number (b) proceeds (S54, S55), The user charges the phone number (b) and notifies the connection result (S56, S57).

As described above, the present invention transmits a telephone connection request from the Internet to the telephone network through the interworking structure of the intelligent network and the Internet, thereby causing the use of the telephone network service from the rapidly increasing Internet users.

In terms of the user, there is an advantage in that the user can connect the phone by simply clicking a specific phone number or icon through the web, and in terms of the web service provider, the user can increase the use of the web service by providing convenience to the user.
