3 is a flowchart illustrating a process of providing local information for a wireless network user accessing the Internet through the intelligent WLAN AP according to the present invention, and FIG. 3 (a) is connected to the Internet through the intelligent WLAN AP according to the present invention. 3 is a flowchart illustrating a process of providing a wireless network access program 203, and FIG. 3B is a flowchart illustrating a process of providing local information to a wireless network user during wireless LAN access shown in FIG. First, referring to FIG. 3 (a), the user of the WLAN user terminal 201 may be connected to the wireless network at any time by driving the AP access program 203 while working by using a laptop. . When the user of the WLAN user terminal 201 runs the AP access program 203 to access the WLAN (301), the AP access program 203 is a WLAN card installed in the WLAN user terminal 201 In step 204, the wireless LAN connection request message is transmitted to the intelligent wireless LAN AP device 206 to request wireless LAN connection (302), thereby proceeding to a state for user authentication processing (303). The AP access program 203 waits for input of a user ID, password or cancellation for authentication processing of the user of the WLAN user terminal 201 (304). First, when the user inputs a user ID, the AP access program 203 receives the input user ID (305) and sends a message 'Checking user' for user authentication to the user side (306). The input user ID is checked for validity (307). If the user ID is valid as a result of the check in step 306, the process returns to the user authentication state 303 and waits for input of the password (304). If the input user ID is not valid as a result of the check in step 306, it is checked whether the number of attempts to input the user ID has been exceeded (308). At this time, if the number of attempts to input the user ID has not been exceeded, the process returns to the user authentication state 303 again and waits for a new user ID input (304). After the confirmation failure message is sent to the user side (309) is terminated.

As described above, if the inputted user ID is valid (307), it returns to the user authentication state 303 again and waits for the next input (304). Then, if a password is input from the user (310), the inputted password is entered. Check if valid (311). If the inputted password is not valid as a result of the check in step 311, it is checked whether the number of attempts to input the password has been exceeded (308). At this time, if the number of password input attempts is not exceeded, the process returns to the user authentication state 303 again and waits for a new password input (304). If the number of password input attempts is exceeded, the AP access program 203 notifies the password verification failure. The message is sent to the user side (309) and ends.

However, if the inputted password is valid as a result of the check in step 311, a user confirmation success message is sent to the user side (312), and the message 'IP assignment in progress' is continuously sent to the user side (313). Subsequently, the AP access program 203 continues to perform tasks related to IP allocation (314). If the IP allocation is successfully performed (315), if the IP is normally allocated, the wireless LAN connection success message is sent to the user (316), the local information service icon is activated (317), and the access state is reached (318). If the IP allocation fails, the AP access program 203 sends an access failure message to the user side (319) and terminates the AP access (320). On the other hand, when receiving a cancellation from the user during the input standby of step 304 (321), the AP access program 203 proceeds to step 321 described above by terminating the AP connection (321), the series of processes This ends.

Next, referring to FIG. 3 (b), a process of providing the regional information for the wireless network user by the local information server in the wireless LAN connection state as described in FIG. 3 (a) will be described. When the network state function request is received from the user in the connection state 318 of FIG. 3 (a) (322), the current state of the WLAN network connection state is displayed on the monitor (323), and the state is again connected (318). In addition, when a local information request is received from the user in the connected state 318 (324), the AP access program 203 sends the corresponding local information request to the local information server 210 (325). After receiving the corresponding area information from the area information server 210 (326) and displaying it on the user monitor (327), the AP access program 203 continuously maintains the connection state (318). On the other hand, when the disconnected function request from the user in the connected state 318 (328) by ending the current WLAN network connection (329) the process is terminated.

4 is a flowchart illustrating a process of a local information server for providing local information according to the present invention, and a processing procedure of a local information server for providing local information to a user accessing the Internet through an intelligent WLAN AP according to the present invention. It is a flowchart showing. Before the process of FIG. 4 is performed, the regional information server presets an index page (file) including regional information for each WLAN user terminal connected to the Internet and for each access time. That is, the region information index file is set according to the IP information held by the WLAN user terminal, and the region information file is also set according to the time when the WLAN user terminal accesses the WLAN network. Herein, the WLAN user terminal and the access time are grouped into a plurality of IP groups of IPs of the plurality of WLAN user terminals, and grouped into a plurality of hourly groups according to the WLAN network access time of the WLAN user terminal. Stored in the storage means. As a result, it is determined to which IP group the IP of the WLAN user terminal connected to the Internet is included, and the local information index file in the corresponding IP group is searched and transmitted to the user terminal. In addition, by checking the time the user terminal accesses the Internet, the local information index file within the corresponding time is searched and transmitted to the user terminal.

Hereinafter, with reference to FIG. 4, it demonstrates in detail. First, when the local information server 210 is started (401) is a state waiting for a user request (402). When the local information service request is transmitted from the user through the AP access program 203 (403), the local information server 210 analyzes the message requested by the WLAN user terminal 201 and extracts the IP address of the user terminal. In operation 404, an IP section search is performed in which IP section is included (405). As a result of the search, it is determined whether the corresponding IP section exists (406), and if the corresponding IP group is determined, the search is performed once again to find an hourly index provided by the IP group (407). That is, the hourly index is searched in the found IP section. Then, it is determined whether the user's local information request time falls within the special event time (408). As a result of the determination in step 408, if the user's local information request time falls within the special event time, the local information including the special event is transmitted to the user (409), and the waiting state is reached (412). As a result of the determination in step 408, if the user's local information request time does not belong to the special event time, the local information not included in the special event is transmitted to the user (410) and is in a waiting state (412). Here, the special event refers to local information corresponding to the access time. Among local information, the data contains dynamic information that is effective at a specific time. For example, when a user connects at lunchtime, the user is informed of an event (discount coupon) provided at a particular restaurant in the area at that time. As another example, in the case of a store opened today, information on which menu is free or a souvenir for the day can be provided together with local information as an event. For such a specific event, local festivals or sports game information may be provided differently according to time, and may be provided depending on the provider.

Meanwhile, if the request is transmitted from an IP not included in the local information DB 212 when the IP section is searched, if it does not exist in the corresponding IP section in step 406, the information indicating that the information of the corresponding region is not registered. The message is sent (411) and the server is waiting (412).
