BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a configuration of an advertisement distribution system according to the embodiment. In this figure, 1-1 to 1-N are hot spots, for example, convenience store stores belonging to the same convenience store chain. In these hot spots 1-1 to 1-N, 2 is a client, 3 is an access point, and these are connected by a short-range wireless LAN. Reference numeral 5 denotes a remodeling proxy server installed at the headquarters of a convenience store chain, which is connected to the access points 3 of the hot spots 1-1 to 1-N via a communication line, and connected to the Internet 7 via a router 6. It is connected.
[0010]
Reference numeral 8 denotes an advertisement distribution block. In the advertisement distribution block 8, reference numeral 9 denotes a Radius (Remote Authentication Dial-in User Service) server, which internally has a map of user IDs and client IPs (reference table), and authenticates the hot spot 1 from the access point 3. Performs user and client authentication upon request. Reference numeral 10 denotes an advertisement server, which has a database 10a storing profiles of advertisement contents, an area to which the client 2 belongs, user preferences, and the like, and distributes advertisements via the router 11 in response to a request from the proxy server 5. Reference numeral 12 denotes a Web server that publishes a Web page.
[0011]
Next, the operation of the above-described advertisement distribution system will be described with reference to FIGS. FIG. 2 is a flowchart showing the overall operation of the system. Hereinafter, description will be made with reference to this flowchart.
First, when the user connects the client 2 to the access point 3 (see reference numeral 1), the access point 3 transmits the user ID transmitted from the user and its own client IP address to the Radius server 9 (reference numeral 2). ▼). The Radius server 9 authenticates the user ID and the client IP address based on the internally stored map, and returns the result to the access point 3.
[0012]
Next, the access point 3 notifies the proxy server 5 of the IP address of the connected client 2 by an SNMP (Simple Network Management Protocol) trap (reference numeral {circle around (3)}, step Sa1 in FIG. 3). The proxy server 5 stores the IP address (R1 (c1)) received from the access point 3 in the table T1 (see FIG. 3) set in the memory, and then stores “unknown” corresponding to the IP address. The data indicating "connection (advertisement not delivered)" is stored in the table T1 (step Sa2 in FIG. 3).
[0013]
On the other hand, after connecting to the access point 3 described above, the user accesses the Web server 12 from the client 2 to view a desired home page ((4) in FIG. 2, step Sb1 in FIG. 4). The proxy server 5 checks the IP address R1 (c1) of the client 2 against the table T1 to determine whether the access is the first access (unconnected (advertisement not delivered)) (step Sb2). If the access is the first access, the client server notifies the advertisement server 10 of the client IP address R1 (c1) and requests distribution of the advertisement ((5) in FIG. 2, step Sb3 in FIG. 4, step in FIG. 5). Sc1).
[0014]
The advertisement server 10 receives the request from the proxy server 5 and notifies the client IP address R1 (c1) transmitted from the proxy server 5 to the Radius server 9 ((6) in FIG. 2, step Sc2 in FIG. 5, FIG. Step Sd1). The Radius server 9 identifies the user ID / u1 corresponding to the client IP address R1 (c1) notified from the advertisement server 10 (step Sd2), and notifies the user ID / u1 to the advertisement server 10 (FIG. 2). {Circle around (7)}, Step Sd3 in FIG. The advertisement server 10 receives the user ID u1 (step Sc3 in FIG. 5), detects the preference of the user ID u1 and the area to which the client IP address R1 (c1) belongs from the profile recorded in the storage unit in advance, The advertisements related to those preferences and areas are read from the database 10a (Step Sc4 in FIG. 5). Then, the read advertisement is distributed to the proxy server 5 ([8] in FIG. 2, step Sc5 in FIG. 5).
[0015]
The proxy server 5 distributes the advertisement received from the advertisement server 10 to the client 2 ((9) in FIG. 2, Step Sb4 in FIG. 4). Next, the proxy server 5 writes data indicating “connected” to the internal table T1 corresponding to the IP address R1 (c1) (Step Sb5 in FIG. 4).
[0016]
Next, when the user sees the advertisement and makes a reconnection request to the Web server 12 ((10) in FIG. 2), the proxy server 5 receives the request and receives the IP address R1 (c1) of the client 2. Is compared with the table T1 (step Sb2 in FIG. 4). Then, since the IP address R1 (c1) is "connected", connection to the Web server 12 is made in the same manner as a normal proxy server (step Sb6).
[0017]
As described above, according to the above-described embodiment, the function of checking the advertisement delivery is provided in the proxy server 5 and whether or not the advertisement delivery has already been performed by the proxy server 5 is checked. It is possible to check whether the advertisement has been delivered without installing a special program.
[0018]
The above proxy server 5 has a computer system inside. The process of the above-described operation is stored in a computer-readable recording medium in the form of a program, and the above-described processing is performed by reading and executing the program by the computer system. Here, the computer system includes an OS and hardware such as peripheral devices.
