2. Description of the Related Art In recent years, with the development of communication networks such as the Internet, displaying advertisements on the Internet has become commonplace. Internet service providers (hereinafter referred to as ISPs) provide advertisements for various types of information, such as news information, car information, and bookstore information, on the Internet. In recent years, free ISPs have been introduced that distribute such information free of charge. Instead of letting registered users use the Internet free of charge, free ISPs semi-forcedly distribute guidance for various services such as advertisements, and registered users who see this guidance pay when they use these services It depends on the price.

A registered user who receives such various information semi-forcibly does not want to receive the above-mentioned various guidances because the Internet communication which is the original purpose can be performed without being influenced by uninteresting information. This is the true intention, and therefore, it has been a problem for the free ISP side how to efficiently distribute advertisements.

As a means for efficiently displaying these advertisements, Japanese Patent Laid-Open Publication No. Hei 10-310344 “System for Scheduling and Controlling the Distribution of Ads in a Communication Network” has been proposed for each of a plurality of advertisements. A time distribution controller for allocating time available in an advertising area in a display of a remote computer among the plurality of advertisements as a function of at least one of a desired time frequency and a desired geometry; A system for scheduling and controlling the distribution of advertisements in a communication network is disclosed, comprising a data communication controller that distributes the plurality of advertisements according to a time distribution by the controller.

Japanese Patent Laid-Open No. 2000-89708 "Advertisement system using the Internet" discloses an advertisement system in which an advertisement information transmitting device and an advertisement information receiving device are connected via an Internet communication network. Discloses an advertisement system using the Internet, characterized by comprising an automatic receiving means for automatically accessing the advertisement information transmitting device at a preset time and receiving the advertisement information, without requiring the user to operate the system. Also automatically accesses a server at a predetermined time so that the latest advertisement information can be received by a personal computer.

Further, Japanese Patent Application Laid-Open No. 2000-148675 "Apparatus and method for providing customized advertisement on WWW" is an apparatus for providing an electronic advertisement to a combined client system, and stores an advertisement and its campaign information. A database, and an advertisement server that creates an electronic advertisement that can be used by the client system.
Means for performing a customization process for customizing the electronic advertisement delivered to each client system, and proposes a system and the like for selecting and delivering customized advertisements on the WWW on the Internet. I have.

However, the means for distributing the free advertisement is to distribute dial-up access software dedicated to free ISPs to users for free,
When the registered user accesses the free ISP, the advertisement is distributed at the timing of executing the dial-up access software.
OS (Operating) of the Internet terminal used by the registered user
It is necessary to create dial-up access software of a number corresponding to the type of System), and there is a problem that a huge cost is required for the free ISP side.

[0008] Further, in the case of an expert user who is accustomed to Internet communication, it is conceivable to access by a method that does not use the dial-up access software. Therefore, it has been difficult to efficiently distribute advertisements by this distribution method.

[0009] On the other hand, when viewed from the advertiser side, if there is an ISP that distributes free advertisements to many consumers even if the advertiser pays the advertisement fee, a specific advertisement becomes a member of the provider. Since the distribution of the registered registrants can be limited, the advertisement effect can be improved as compared with the normal TV advertisement, but as described above, the current ISP distribution system has been impossible.

[0010]

Means for Solving the Problems The inventor of the present invention has made intensive studies to solve the problems to be solved, and found that a remote access server implemented based on a UNIX system such as Linux is connected to an access center on the ISP side and a registered user. Installed in the middle of a public line network between the Internet and the Internet, and found that it is possible to distribute a free advertisement ignoring the specified URL only at the first access by the WEB browser after dial-up connection. did it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the whole system of the present invention. This system includes an Internet terminal 1 of a registered user connected to an Internet service provider 3 for delivering advertisement information via a public line network 2.
However, as a characteristic, both are connected via the remote access server 4.

The remote access server 4 is one of the most important components for realizing the present system. The reason is that the remote access server 4 uses a DTA such as a modem / ISDNTA of a registered user. This is because communication data via the public line is aggregated.

This system dials up by customizing the implementation of the data link layer protocol PPP running on the remote access server, monitoring PPP frames at the data link layer level, and filtering and customizing IP datagrams. An advertisement page delivered by an Internet service provider is displayed on a web browser ignoring a specified URL only at the first access after connection, and an advertisement is delivered to registered users free of charge.

The above PPP (Point to Point protocol)
Is a one-to-one connection between a client and a server.
Point), this system has a function as shown in FIG. 3 by utilizing the PPP standard as it is.

That is, after establishing communication between network layers, communication data (IP datagram) exchanged between PPP (data link layer) and IP (network layer)
HTTP to other WEB servers
(Hyper Text Transfer Protocol) request,
Next, the HTTP request is replaced with an HTTP request to the web server for advertisement, and a function of transmitting the advertisement page from the web server for advertisement to the web browser of the transmission source is added.

Hereinafter, the present invention will be described in detail with reference to examples, but the scope of the present invention is not limited thereto.

[0021]

[Embodiment 1] FIG. 4 shows that an automatic advertisement distribution system according to the present invention enables communication between network layers,
FIG. 3 illustrates a procedure from extracting an HTTP request to a server to transmitting an advertisement page, which will be described below for each procedure.

(1) A WEB browser is started on the Internet terminal 1 which is a client PC of a registered user, and a WEB server (www.foo.co.jp) on the Internet
Issues a connection request. (2) The modem connected to the Internet terminal 1 of the client PC dials toward the remote access server of the ISP, and communication on the physical layer becomes possible (establishment of the physical layer). (3) Negotiate and set data link layer parameters (frame format, user authentication protocol, etc.) with the PPP of the remote access server (establish data link layer). (4) The user authentication protocol (PAP + RA) negotiated in (3) above
DIUS) for authentication. (5) Network layer parameters (IP address, DN
S server address, etc.) to the remote access server's PP
Set by negotiating with P (establishment of network layer). (6) Notifying the user access management server that the network communication has started using the registered user name used for authentication as a parameter (the user access management server stores the advertisement URL for the user who has received the access notification in the user / advertisement association DB From the server). (7) The HTTP request counter inside the remote access server PPP is initialized. (8) Of the datagrams from the data link layer (hereinafter referred to as PPP) to the upper network layer (hereinafter referred to as IP), the HTTP request counter = 0 = 0 && T
Monitor and extract a PPP frame that satisfies the condition of the port number 80 for CP protocol && TCP protocol && (9) TC for HTTP request extracted in (8) above
The destination address of the IP datagram containing the P segment (w
ww.foo.co.jp) is replaced with an address addressed to the WEB server in the free ISP. Also, the HTTP in the TCP segment
Request (GET http://www.foo.co.jp/HTTP/1.
0 ...) is also an HTTP request (GET ht
tp: //www.free.ne.jp HTTP / 1.0 ...) and pass it to the IP layer. (10) HTTP for advertising display replaced in (9) above
Upon receiving the request, the advertisement WEB server returns an advertisement display HTTP response to the registered user of the transmission source. (11) When the TCP segment including the advertisement display HTTP response transmitted in (10) is passed from the IP layer,
The source address of the P datagram is (www.free.ne.j
This is the state of p). However, at the registered user's IP layer,
Destination address of the original HTTP request (www.foo.co.j
p), the source address of the advertisement display HTTP response IP datagram is replaced with the original address of the HTTP request (www.foo.co.jp), and the PPP Pass to (12) An advertisement page is displayed on the WEB browser of the registered user receiving this packet.

That is, in the system of the present invention, the PP
The key technology in processing at P is the extraction and modification of IP datagrams at the PPP (data link layer) level. Among them, changes in IP datagrams and TCP packets include changes in end and start IP addresses, TCP
IP checksum, TC according to data change in packet
In addition to problems such as recalculation of the P-checksum, the problems due to the TCP protocol being a complicated protocol including error correction must be solved.

The user access management server used in the system of the present invention performs access management of a user who has completed user authentication (RADIUS) in the remote access server in the following procedure. (1) Receive the user authentication completion notification from the remote access server. (2) Access the user advertisement association DB server and acquire the advertisement page URL for the user whose authentication has been completed. (3) Communication is performed in response to an advertisement page inquiry from the remote access server. (4) Perform alternative services until the user / advertisement association DB server is constructed.

Further, the user / advertisement association DB server
This is a key point in operating this system. This DB server stores user information (age, occupation, hobby, activity area, etc.), and links to this information and searches for matching advertisement pages. Is being done.

[0026]

According to the present invention, a free ISP operated at an advertiser's request for an advertisement fee creates dedicated dial-up access software as in the past in order to introduce the system of the present invention into a free ISP facility. This greatly contributes to operational cost reduction.

Further, since the advertisement distribution is always performed at the first timing when the registered user accesses the Internet, the free ISP side can effectively distribute the advertisement to the registered user.
