A method to provide single address of Information Provider with Web Infoshop Service Systems for Advanced Information Communication Processing System

The present invention relates to a method for providing a single information provider address of a web infoshop service system in a large capacity communication processing system. In particular, the web infoshop service system (WISS :) connected to an advanced information communication processing system (AICPS) is provided. By assigning a representative information provider (IP) address to a Web Infoshop Service System, the subscriber should use this representative IP address, and the conversion of the WISS to an actual IP address is performed by the WNAS (Web Network Access) of the large-capacity communication processing system. Subsystem).

Almost all homes and businesses are subscribed to the public telephone network (PSTN), but the service is mainly voice-based. However, as the information society progresses, data transmission between computers is widely required, and various information providers are on the rise and the demand for access to the packet network is rapidly increasing.

As a result, services that are connected to packet-switched networks have increased using telephone lines used in homes, and for this purpose, information communication processing systems have been introduced for connection between public telephone networks and packet networks. In addition, as the network has evolved, various networks have been newly constructed. Thus, the conventional communication processing system has been improved to a large capacity communication processing system in order to connect them integrally and further increase processing capacity.

1 is a diagram illustrating a network configuration using a large capacity communication processing system, wherein the large capacity communication processing system 130 is a telephone network matching device (131: Telephone Network Access Subsystem) for connection with a public telephone network 120, for connection with an ISDN network. ISDN Network Access Subsystem (132: ISDN Network Access Subsystem), High Speed Switch Module (135: HSSF) to connect each matching device to each other, Internet Matching Device (133,134: WNAS) for connecting to the Internet, etc. The user terminal 111 of the subscriber 110 or the user terminal 151 of the ISDN subscriber 150 is connected to the Internet network 170.

In this case, the user terminals 111 and 151 mean a personal computer (PC) or a hightel terminal, and are connected between the public telephone network subscribers 110 and the public telephone network 120 or between the ISDN subscribers 150 and the ISDN network 160. ) Are connected via modems 112 and 152.

In addition, the public telephone network 120 or ISDN network 160 and the mass communication processing system 130 is connected by a predetermined number of E1 links, WNAS (133, 134) of the mass communication processing system is WISS 140 through the Ethernet (143) ) Is connected to the router 145, and is connected to the Internet network 170 through the router 145.

Meanwhile, the WISS 140 is a proxy server used to provide a web infoshop service in the mass communication processing system 130, and the user designates it in a web browser. Currently, one WISS 140 is connected and used for one mass communication processing system 130.

The WISS 140 performs an alternative authentication function between the user and the paid CP (Content Provider) site, so that the user can access the site without inputting an ID or password, and the paid CP collects the billing fee. At this time, in order for the user to be provided with the web infoshop service, the user must know the WISS 140 address of the mass communication processing system 130 to which the user accesses.

2 is a diagram illustrating a message format according to whether or not a proxy server is used. FIG. 2A illustrates a case where a proxy server is not used, and FIG. 2B illustrates a case where a proxy server is used. At this time, the proxy server 230 is located between the client 210 and the server 220, and refers to a relay role for transmitting a request received from the client 210 back to the server.

In addition, the WISS 140 is in charge of the proxy server role in the mass communication processing system 130 shown in FIG.

When the proxy server 230 is not used, only a path of a document is specified in the request message transmitted from the client 210 to the server 220. However, when the proxy server 230 is used, the proxy server 230 is used. Since the proxy server 230 needs to know the actual IP address of the server 220 that the client 210 sends the request message, the proxy server 230 includes information on the IP address and the protocol used.

Here, HTTP is a communication protocol used for communication between the client 210 and the server 220 in the World Wide Web (WWW) service. HTTP is able to effectively send and receive data in the form of hypermedia in a distributed network environment, and operates on a simple principle that the server 220 receiving the request of the client 210 sends an answer. The client 210 makes a request to the server according to the URL format, and the server 220 receiving the request transmits the retrieved information to the client 210.

HTML is also a language for creating hypertext.

Hypertext is a way of organizing information in text files to create a powerful interactive interface. In addition to the text, the dynamic linking with other media such as graphics, pictures, video, and sound is called hypermedia. HTML is actually called hypermedia, and it can link not only documents but also various media such as graphics and sound.

In addition, a Uniform Resource Locator (URL) is a standard address used to indicate the location of various resources on the Internet. In the WWW, the client 210 requests specific data from the server 220 to specify a protocol, a service name, and a location. The system used at this time is standardized by a URL. The URL is described according to the format shown in Table 1 below.

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

3 and 4 are flowcharts illustrating an internet access method using the WISS 140 as a proxy server according to the present invention, and FIG. 3 illustrates a process P300 of the WNAS 133 and 134 of the mass communication processing system 130. 4 is a flowchart illustrating a process P400 in the WISS 140.

In order to apply the present invention, a representative IP address of the WISS 140 must first be specified. Each user may designate a representative IP address of the WISS 140 as a proxy server in a web browser of the user terminals 111 and 151.

In addition, the WNAS 133, 134 of the large-capacity communication processing system 130, in addition to the routing function between the user terminal (111, 151) and the Internet network 170, the actual IP for the datagram (Datagram) coming into the representative IP address of the WISS (140) It must have a function to change the address.

In addition, the WISS 140 performs a proxy server function, and analyzes a request message delivered to the user, performs a user authentication in the case of a request for a paid CP, receives a user request URL, and delivers the user request URL to the user. If the requested URL is the representative IP of the WISS 140, it should have a function of showing its own content.

On the other hand, when the WISS 140 is designated as a proxy server, data flowing from the subscriber to the Internet network 170 is transmitted to the user terminal 111,151-> TNAS 131 or INAS 132-> switch (HSSF)-> WNAS ( 133,134)-> WISS (140)-> Router (145)-> Internet network 170, and the data flowing from the Internet network 170 to the subscriber is the Internet network 170-> Router (145)-> WISS 140-> WNAS 133, 134-> Switch (HSSF)-> TNAS 131 or INAS 132-> User terminal (111, 151).

First, a predetermined subscriber designates a representative IP address of the WISS 140 in his user terminal 111 as a proxy server. As an example, assume that the representative IP address is designated as A.B.C.D.

A case in which a subscriber sends data destined for the internet network 170 will be described.

If the subscriber enters the URL wxyz / index.html, the message http: // wxyz / path / index from the subscriber (client) to the proxy server 140 (WISS) according to the message format when using the proxy server shown in Fig. 2b. A message of .html is sent. At this time, ″ w.x.y.z ″ indicates the location of the resource, ″ path ″ indicates the path of the location where the resource exists, and ″ index.html ″ indicates the desired data name.

In addition, if the representative IP address of the WISS 140 as A.B.C.D as in the above embodiment, the destination IP address of the corresponding IP datagram will be set to A.B.C.D.

Then, a message is input to the WNAS (133, 134) of the mass communication processing system 130, the routing processing module of the WNAS (133, 134) is changed to the actual IP address of the WISS 140, and then forwarded to the WISS (140) server The WNAS process P300 will now be described with reference to FIG. 3, including the case where a message enters the WNAS 133 and 134 from the Internet network 170.

At this time, it is assumed that the actual IP address of the WISS 140 is a.b.c.d.

In the IP datagram input step S310, an arbitrary IP datagram is input to a predetermined WNAS 133 of the AICPS 130.

In the source IP extraction and determination step S320, the WNAS 133 extracts a source IP address from the input IP datagram, and determines whether the extracted source IP address is an actual IP address of the WISS 140. Source IP is where the message was sent.

That is, if it is assumed that the actual IP address of the WISS 140 is a.b.c.d, the WNAS 133 determines whether the extracted source IP is a.b.c.d.

In the source IP setting step (S330), when the extracted source IP address is the actual IP address of the WISS 140 as a result of the determination in the source IP extraction and determination step (S320), the extracted source IP address is represented by the representative IP of the WISS 140. Set to address.

That is, if the extracted source IP is a.b.c.d, it means that the message is sent to the subscriber because it is the WISS 140. Therefore, the source IP address is replaced with A.B.C.D, which is a representative IP address of the WISS 140.

In the destination IP extraction step (S340), if the extracted source IP address is not the actual IP address of the WISS 140 as a result of the determination in the source IP extraction and determination step (S320), the corresponding destination IP address is received from the received IP datagram. Extract.

That is, if the extracted source IP is not a.b.c.d, the corresponding destination IP address is extracted from the received IP datagram.

In the destination IP setting step S350, when the destination IP address extracted in the destination IP extraction step S340 is the representative IP address of the WISS 140, the destination IP address is set as the actual IP address of the WISS 140.

That is, when the extracted destination IP is A.B.C.D, since the message is transmitted from the subscriber side toward the Internet network 170, the destination IP is changed to a.b.c.d, which is the actual IP address of the WISS 140.

In step S360, the WNAS 133 reads out necessary routing information from a predetermined routing table according to the source IP address and the destination IP address.

In step S370, the message is transmitted to the corresponding layer according to the read routing information.

That is, after determining which network to transmit the message to using the routing information, the message corresponding to the local transmission is transmitted to the TCP layer, the message corresponding to the Ethernet transmission is transmitted to the Ethernet driver, and the serial transmission is performed. The corresponding message is sent to the link layer driver.

Now, the process P400 in the WISS 140 will be described in detail with reference to FIG. 4.

In the HTTP packet input step S410, a predetermined HTTP packet is input to the WISS 140, and IP information of the URL of the packet is read.

In the destination IP setting step (S420), if the IP information of the URL is the representative IP address of the WISS 140, the destination IP address is set to the actual IP address of the WISS 140, and in other cases, the destination IP address is set to the URL. Set to IP information.

That is, the WISS 140 determines whether the IP information of the URL is A.B.C.D in order to know whether the message is sent to the WISS 140. If the IP information of the URL is not A.B.C.D, it is not a packet sent to itself, so the destination IP address is set as the IP information of the URL. However, if the IP information of the received packet is A.B.C.D, the packet is sent to itself, so the destination IP address is set to its actual IP address a.b.c.d.

In the message transmission step (S430), after removing the IP information from the URL of the message to be transmitted, the destination IP address predetermined request message set in the destination IP setting step (S420) is transmitted.

According to the present invention, the WISS 140 has one representative IP address and changes to the actual IP address of the WISS 140 so that the WNAS 133 and 134 can perform a convenient and transparent service to the user. .

In addition, when there are multiple servers playing a common role, it is possible to connect to one server address without having to know each server address, thereby eliminating the need for users to remember IP addresses. There is.
