1, when a user requests access to a specific web site through a web browser in order to receive a wireless Internet service through a WIFI network, the terminal 10 transmits a TCP (Transmission) message to the Wi- Control Protocol) connection request packet.

The terminal 10, which has transmitted a TCP connection request packet to the Wi-Fi AP 20, receives a TCP connection response packet from the Wi-Fi AP 20 in response thereto, and establishes a TCP session connection with the web server 60, A HyperText Transfer Protocol (HTTP) request packet for requesting a web page requested by the user to the AP 20 and a connection from the packet control server 40 to the advertisement server 50 via the Wi-Fi AP 20 in response thereto Lt; / RTI >

The HTTP response packet includes an HTML Template ID, an IP (External IP) address of the terminal 10, a URL of a web page to which the terminal 10 is originally connected, a URL (Uniform Resource Locator) of the advertisement server 50 A document type of a web page to which the terminal 10 originally attempts to access, a document domain of a web page to which the terminal 10 is originally connected, an advertisement type (for example, a full advertisement, a non-advertisement, etc.) .

The terminal 10 releases the TCP session connection connected to the web server 60 based on the FIN flag set in the header of the HTTP response packet received from the packet control server 40, Sets a TCP session connection with the advertisement server 50 based on the advertisement server URL included in the packet, and transmits an HTTP request packet (hereinafter, referred to as an 'ad request packet') requesting the advertisement server 50 to the advertisement server 50 And receives an HTTP response packet including the advertisement content URL and the advertisement inventory (advertisement exposure area) information from the advertisement server 50 in response thereto.

The terminal 10 transmits an HTTP request packet requesting the advertisement contents to the advertisement server 50 by using the advertisement contents URL included in the HTTP response packet received from the advertisement server 50, While the content is received, the web page URL to which the terminal 10 originally intended to access (the terminal temporarily stores the web page URL information with the information contained in the HTTP response packet received from the packet control server, And transmits the HTTP request packet requesting the web page to the web server 60, receives the web page from the web server 60, and provides the web page to the user.

At this time, the terminal 10 may simultaneously transmit the HTTP request packet to the advertisement server 50 and the web server 60 according to the type of the advertisement content determined by the advertisement server 50 and the advertisement inventory (advertisement exposure area) After transmitting the HTTP request packet to the web server 60 first, the HTTP request packet may be transmitted to the advertisement server 50. Alternatively, the HTTP request packet may be transmitted first to the advertisement server 50 and then transmitted to the web server 60 It may transmit an HTTP request packet or may not transmit an HTTP request packet to the web server 60 in some cases.

Also, when providing the advertisement contents received from the advertisement server 50 and the web page received from the web server 60 to the user, the advertisement contents may be first provided to the user according to the advertisement type, and then the web page may be provided , And the advertisement content and the web page may be simultaneously provided through different screen frames by dividing the screen.

The terminal 10 may be implemented as a terminal capable of providing a wireless Internet service by connecting to a Wi-Fi AP such as a smart phone, a tablet PC, a laptop, and the like.

When the terminal 10 enters the service area of the WiFi AP 20, the WiFi AP 20 authenticates the terminal 10 to confirm whether the terminal is allowed to allow the wireless Internet service, The terminal 10 receives an IP (external IP) and transmits a TCP connection request packet in order to receive the wireless Internet service. The terminal 10 receives the packet and transmits it to the web server 60, And receives a TCP connection response packet from the web server 60 in response thereto and transmits the TCP connection response packet to the terminal 10.

In the case where the Wi-Fi AP 20 performs the NAT (Network Address Translation) function, it is possible to operate with the same external IP for different terminals 10, which may cause difficulties in service execution. Accordingly, in this case, a process of sharing the NAT table of the Wi-Fi AP 20 with the packet control server 40 and confirming the internal IP and external IP of the terminal 10 that has transmitted the HTTP request packet from the packet control server 40 The terminal 10 can be identified and provided with a service.

In addition, when transmitting the HTTP GET request packet from the HTTP request packet received from the terminal 10 to the switch 30, the Wi-Fi AP 20 transmits the HTTP GET request packet to the MAC address of the terminal The WiFi AP 20 changes the HTTP address received from the terminal 10 so that the WiFi AP 20 can manage the user's history based on the MAC address of the terminal 10 in the packet server 50. [ The MAC address of the terminal 10 may be further inserted into the header of the HTTP GET request packet before the GET request packet is transmitted to the switch 30.

The switch 30 copies all the packets received through the Wi-Fi AP 20 and transmits the copied packets to the packet control server 40 so that the terminal 10 connected to the Wi- And transmits the packet to the packet control server 40 by copying the packet to the packet control server 40.

The packet control server 40 extracts only the HTTP request packet from among the copied packets transmitted from the switch 30, analyzes the extracted HTTP request packet, and determines whether to provide the advertisement service. At this time, the packet control server 40 performs packet validity checking of the MTU size of the HTTP request packet, the packet reception link, and the like, analyzes the HTTP request packet, compares the obtained parameter information with the service policy information, .

The service policy information may include URL masking information, URL extension masking information, an advertisement transmission period, an HTML template, a blacklist requesting ad rejection, and the like. It is preferable that service policy information is received from the service provider 50 and stored.

When it is determined that the advertisement is provided, the packet control server 40 generates an HTTP response packet for the HTTP request packet and transmits the HTTP response packet to the terminal 10. At this time, in order to release the TCP session connected between the terminal 10 and the web server 60, a FIN flag is set and transmitted in the header of the HTTP response packet transmitted to the terminal 10, 60), a TCP packet with a reset (RST) flag is transmitted. The HTTP response packet transmitted to the terminal 10 includes a terminal identifier (for example, the IP address of the terminal assigned by the Wi-Fi AP, the MAC address of the terminal inserted in the HTTP GET request packet of the user by the Wi- A telephone number of a user registered in association with a customer management server of a business site), and an identifier (e.g., a MAC address of a Wi-Fi AP) of a WiFi AP to which the terminal is currently connected. The service related information is included in the advertisement request packet transmitted from the terminal 10 to the advertisement server 50. The advertisement server 50 recognizes the service related information included in the advertisement request packet and performs the target advertisement service .

The packet control server 40 analyzes the HTTP request packet to determine user information (e.g., IP (external IP) address of the terminal, MAC address of the terminal, MAC address of the WiFi AP to which the terminal is currently connected, etc.) And delivers the extracted user information to the advertisement server 50. In addition, the packet control server 40 may collect an OS installed in the terminal, a browser mounted on the terminal, a URL of a web page to which the terminal 10 originally attempts to access, and transmit the URL to the advertisement server 50 together with the user information.

On the other hand, when the advertisement server 50 receives the advertisement request packet from the terminal 10, the advertisement server 50 transmits the user information included in the advertisement request packet (for example, the IP address of the terminal, the MAC address of the terminal, The MAC address of the currently connected WiFi AP, and the like) and targeting information mapped to each advertisement content, determines advertisement contents to be transmitted to the terminal 10, and determines the advertisement inventory, And then transmits the URL of the advertisement content corresponding to the determined advertisement content and the information about the advertisement inventory to the terminal 10 in the HTTP response packet.

The advertisement server 50 that has transmitted the HTTP response packet to the terminal 10 receives the HTTP request packet requesting the advertisement content from the terminal 10 and transmits the advertisement content in response thereto.

In the present invention, a redirection function for a captive portal is provided. When the terminal 10 has to move to a dependent portal, the advertisement server 50 sends a redirect to the terminal 10 so as to redirect to the URL of the dependent portal. In this case, it is preferable that the terminal 10 does not transmit an HTTP request packet requesting a web page to be originally connected to the web server 60.

When the packet control server 40 and the advertisement server 50 are formed in a plurality of locations in a plurality of locations, the packet control server 40 is established for each business site, and the advertisement server 50 is a centralized one And can operate in conjunction with a plurality of packet control servers 40.

In addition, when the advertisement server 50 can interwork with the customer management server of the business site, the user information DB 58 may receive the user's telephone number from the customer management server of the business site and store the user information.

The user information DB 58 stores user information based on the MAC address of the terminal 10 (e.g., web access information, access business site location, business site information, etc.) using the MAC address of the terminal 10 among the user information acquired by the packet control server 40 A WiFi location in the Internet, etc.) and manage its history. Based on this, the advertisement server 50 can perform a target advertisement service.

5 is a flowchart illustrating a method of providing a web-based advertisement using a Wi-Fi network according to an embodiment of the present invention.

First, the terminal 10, which is allowed to access from the Wi-Fi AP 20, executes a web browser to receive a wireless Internet service and inputs a URL to request access to a specific web site (S10) (TCP SYN packet) to the web server 60 via the Wi-Fi AP 20 and the switch 30 according to the 3 Way Handshake (SYN, SYN-ACK, ACK) The web server 60 that has received the TCP connection request packet transmits a TCP connection response packet (TCP SYN-ACK packet) to the terminal 10 through the switch 30 and the Wi-Fi AP 20, 10 establishes a TCP session connection between the terminal 10 and the web server 60 by transmitting a TCP connection response packet (TCP ACK packet) to the web server 60 (S12).

The terminal 10 establishing the TCP session connection with the web server 60 through the process S12 transmits the HTTP request for requesting the web page to the web server 60 via the Wi-Fi AP 20 and the switch 30, And transmits a request packet (HTTP GET Request packet) (S14).
When the terminal 10 transmits an HTTP request packet to the web server 60 via the WiFi AP 20 and the switch 30 in the above-described process S14, the WiFi AP 20 transmits the HTTP request received from the terminal 10 If the packet is an HTTP GET request packet, the MAC address of the terminal 10 is preferably inserted into the header of the HTTP GET request packet and transmitted.

The HTTP request packet transmitted from the terminal 10 to the web server 60 through the above-described process S14 is copied from the switch 30 to the packet control server 40 (S16). At this time, the HTTP request packet transmitted to the web server 60 by the terminal 10 passes through the switch 30 without modification and is transmitted to the web server 60 as a destination.

Upon receiving the packet copied from the switch 30 through the process S16, the packet control server 40 extracts the HTTP request packet from the packets received from the switch 30 (S18), analyzes the extracted HTTP request packet (S20), and generates an HTTP response packet for the HTTP request packet identified as the advertisement providing object packet according to the determination result, and transmits the HTTP response packet to the terminal 10 (S24).

In step S24, an HTML template is generated in accordance with an advertisement type (for example, a front advertisement, a non-front page advertisement, and the like) to be provided to the terminal 10, and the HTML template is transmitted to the terminal 10 by including it in an HTTP response packet In an embodiment of the present invention, a description will be given of a case where the advertisement type is a non-transition advertisement, for example. If the advertisement type is the full advertisement, the content of the HTML template is changed and the flow after the HTTP response packet is transmitted to the terminal 10 also proceeds differently.

The HTTP response packet generated in the above-described process S24 includes the template ID, the IP (external IP) address of the terminal 10, the URL of the web page to which the terminal 10 is originally connected, the URL of the advertisement server 50, A document domain of the web page to which the terminal 10 is originally connected, an advertisement type (for example, a full advertisement, a non-advertisement, etc.), and the like.

The web server 60 generates an HTTP response packet through the process S24 and transmits the generated HTTP response packet to the terminal 10 in response to the HTTP request packet received from the switch 30, (TCP RST packet) in which a reset (RST) flag is set to release a session connected between the RST 60 and the RST 60 (S22).

In the header of the HTTP response message transmitted from the packet control server 40 to the terminal 10 in step S24, a FIN flag is set in the header of the HTTP response message to release the session connected between the terminal 10 and the web server 60 Is set.

On the other hand, the terminal 10 having received the HTTP response packet from the packet control server 40 through the above-described process S24 is set to the web server 60 in accordance with the FIN flag set in the header of the HTTP response packet (SYN, SYN-ACK, ACK) with the advertisement server 50 based on the URL of the advertisement server 50 included in the HTTP response packet (S26), and transmits an advertisement request packet, which is an HTTP request packet for requesting an advertisement to the advertisement server 50 (S28).

The advertisement server 50 receiving the advertisement request packet from the terminal 10 through the above step S28 transmits the user information included in the advertisement request packet (for example, the IP address of the terminal, the MAC address of the terminal The MAC address of the WiFi AP to which the terminal is currently connected, etc.), the URL information of the web page to which the terminal 10 is originally connected, the current time, the OS of the terminal, the browser information, The advertisement contents to be transmitted to the terminal 10 and the advertisement inventory to display the advertisement contents are determined (S30).

Thereafter, the advertisement server 50 generates an HTTP response packet including the advertisement content URL and the advertisement inventory information corresponding to the advertisement content determined in the step S30, and transmits the HTTP response packet to the terminal 10 (S32).

The terminal 10 receiving the HTTP response packet from the advertisement server 50 through the above-described process S32 receives the web page 60 from the web server 60 and the web server 60 After establishing a TCP session connection by performing Way Handshake (SYN, SYN-ACK, ACK) (S34), it transmits an HTTP request packet requesting a web page to the web server 60, 60, and displays the web page on the screen (S36 to S38).

Then, an HTTP request packet for requesting the advertisement contents to the advertisement server 50 is transmitted based on the advertisement inventory information included in the HTTP response packet received from the advertisement server 50 and the advertisement content URL, The advertisement content is downloaded from the advertisement server 50 (S40), and the downloaded advertisement content is displayed on the advertisement inventory (S42).

As described above, when the HTTP request packet is first transmitted to the web server 60 and then the HTTP request packet is transmitted to the advertisement server 50, for example, It may transmit the HTTP request packet to the advertisement server 50 and the web server 60 at the same time according to the type of the advertisement content and the advertisement inventory (advertisement exposure area) determined by the advertisement server 50, 60 to the advertisement server 50 or may transmit the HTTP request packet to the advertisement server 50 first and then transmit the HTTP request packet to the web server 60, And may not transmit the HTTP request packet to the web server 60 in some cases.

When providing the user with the advertisement content received from the advertisement server 50 and the web page received from the web server 60, the advertisement content is firstly provided to the user using the entire screen according to the advertisement type as described above The web page may be provided or the advertisement content and the web page may be simultaneously provided through different screen frames by dividing the screen.

FIG. 6 is a process chart for explaining the processes S18 to S20 of FIG. 5 in more detail.

First, when the packet control server 40 receives the packet copied from the switch 30 (S18-1), the packet control server 40 checks the TCP destination port number of the received packet (the copied packet) (E.g., 80 or 8080) (S18-2).

If the TCP destination port number of the packet is not the port number for the web service as a result of the determination in the step S18-2, the packet is ignored or discarded (S21). If the TCP destination port number of the packet is the port number for the web service The packet is extracted as an HTTP request packet, and a packet validity check is performed to check whether the extracted HTTP request packet is valid (S19).

In step S19, the validation of the HTTP request packet may be performed using an MTU size, a packet reception link (mirror link), or the like.

If it is determined that the HTTP request packet is not valid as a result of the packet validation in the step S19, the packet is ignored or discarded (S21). If the HTTP request packet is valid, the HTTP request packet is packet- (E.g., IP (external IP) address of the terminal, MAC address of the terminal, MAC address of the WiFi AP to which the terminal is currently connected, etc.) by analyzing the user information A variety of parameter information such as a web page URL to which the terminal originally tries to access, an OS mounted on the terminal, a browser mounted on the terminal, and the like; And HTTP method information (S20-1).
The packet control server 40 transmits the user information acquired in the HTTP request packet (for example, the IP address of the terminal, the MAC address of the terminal, the WiFi AP currently connected to the terminal, A MAC address of the terminal 10, an OS installed in the terminal, a browser mounted on the terminal, and a URL of a web page to which the terminal 10 is originally connected, to the advertisement server 50.

Thereafter, various parameter information obtained through the above-described process S20-1 is compared with service policy information to determine whether to provide an advertisement. First, based on the HTTP method information acquired through the above-described process S20-1, It is checked whether the request method of the packet is 'GET' (S20-2).

If the request method of the HTTP request packet is 'GET', the corresponding packet is ignored or discarded (S21). If the request method of the HTTP request packet is 'GET', the terminal 10 (S20-3) whether the extension of the web page URL to which the web page is originally connected is the masked URL extension.

If the extension of the web page URL to which the terminal 10 is originally connected is a masked URL extension as a result of the checking in the step S20-3, the packet is ignored or discarded (S21) If the extension of the page URL is not the masked URL extension, it is checked whether the web page URL to which the terminal 10 is originally connected includes the masked URL (S20-4).

If the URL of the web page to which the terminal 10 is originally connected includes the masked URL, the terminal 10 ignores or discards the packet (S21). If the URL of the web page If the page URL does not include the masked URL, the terminal identifier (for example, the IP (external IP) address of the terminal assigned by the Wi-Fi AP, the MAC address of the terminal inserted in the HTTP GET request packet of the user by the Wi- , A telephone number of a registered user in cooperation with a customer management server at the business site (S20-5), checks the last time the advertisement was provided to the identified terminal identifier, and subtracts the last advertisement providing time from the current time It is checked whether the time has exceeded the set advertisement transmission period (S20-6).

As a result of the checking in step S20-6, if the time obtained by subtracting the last advertisement providing time from the current time does not exceed the set advertisement transmission period, the packet is ignored or discarded (S21) When the time exceeds the set advertisement transmission period, the packet is determined to be an advertisement providing target packet, and the advertisement providing time of the corresponding terminal identifier is updated to the current time (S20-7).

Thereafter, an HTTP response packet for the HTTP request packet determined as the advertisement providing object packet is generated and transmitted to the terminal 10 (S24).
