The plurality of WLAN access points 120 are connected to the switch 130 and the controller 170 by wire or wirelessly or to other WLAN access points 120.

The WLAN access point 120 controls the traffic transmitted and received by the WLAN device 110 or performs handover with respect to the WLAN device 110 communicating while moving between different WLAN access points 120. Hand Over) function and necessary authentication function can be performed. Since the function and detailed configuration of the WLAN access point 120 is already known, a detailed description thereof will be omitted.

The switch 130 functions to exchange traffic transmitted and received between the plurality of WLAN access points 120 and the gateway 140.

The switch 130 performs a function of communicating with the controller 170 for user authentication and authentication of a place where the user is connected.

For example, the switch 130 is a wireless LAN device 110 such as a user ID (ID) and password or a MAC (Media Access Control) address input by the user of the wireless LAN device 110 for user authentication. A unique ID of the ID is transmitted to the controller 170.

In addition, the switch 130 includes an ID (ID) of the WLAN access point 120 to which the WLAN device 110 is connected or various WLAN access points 120 for authentication of a place where the user is connected. The VLAN (Virtual LAN) ID (ID) is transmitted to the controller 170.

In this case, the switch 130 may drop a data packet transmitted by the WLAN device 110 or connect to a destination of the data packet according to the authentication result.

The authentication server 150 performs a user authentication function for a user using the world garden service of the present invention.

The user authentication may authenticate the user's account through the user's ID and password, or use a unique ID (eg, MAC address) of the WLAN device 110 used by the user. You can also do it in combination.

To this end, the authentication server 150 stores a user ID (ID) and password registered by users who want to use the world garden service of the present invention and MAC addresses of the WLAN devices 110 used in the world garden site. (Not shown).

The policy server 160 performs authentication of a place where the user is connected, authentication of a time when the user is connected, authentication of an Internet site to which the user is connected, and an amount of traffic transmitted and received by the user's WLAN device 110. Check and perform the function to control wireless internet access.

In this case, the authentication of the place where the user is connected may include an ID (for example, a MAC address) or a plurality of WLAN access points 120 of the WLAN access point 120 connected to the user's WLAN device 110. It can be performed using a VLAN (Virtual LAN) ID (ID) including these.

The authentication of the time that the user accesses the user ID, the ID of the WLAN device 110 of the user, the ID or VLAN ID of the WLAN access point 120 to which the WLAN device 110 is connected, and the like. The user accesses a single WLAN access point 120, the total time of day access in the world garden site, and the time of access for one month in the world garden site.

As described above, since the present invention aims to allow a plurality of WLAN device users to use the Internet service for free, it is necessary to control the use time for each user through authentication of the place and time the user is connected. .

At this time, the usage time is controlled by managing the total time used in the world garden site on a daily, weekly or monthly basis for each user.

In addition, when the use time is controlled based on the day, the place where the user is connected is managed. For example, if a world garden site has two hours of access for one user per day and one hour of internet access in one place, the user can spend more than one hour in one place. No, you have to move to another place. That is, the measurement of the use time and the control thereof are made based on the place where the user is connected.

The policy server 160 performs authentication of an Internet site that a user accesses. In the present invention, an Internet site that a user can access includes an Internet site that is allowed access for all users, and a world garden service provider for each user. Are separated into allowed internet sites.

Here, the Internet site that is allowed access to all users may be a major portal site including mail, finance, shopping, media, etc., which may be variously selected and changed according to the policy of the World Garden Service Provider. .

Internet sites that are allowed for each user are a limited number of Internet sites that are requested by each user and allowed by the World Garden service provider among those who do not allow access to all users. This may also be variously selected and changed according to the policy of the World Garden Service Provider.

In addition, the policy server 160 controls the wireless Internet access by checking the amount of traffic transmitted and received by the user's WLAN device 110 or the amount of traffic of each Internet site to which the user accesses. It is to maintain the quality of Internet service.

The policy server 160 controls the maximum traffic and the cumulative traffic amount at the moment when the wireless LAN device 100 or each Internet site to which the user accesses is transmitted or received. To this end, the World Garden service provider provides a corresponding policy and Set the parameter.

To this end, the policy server 160 stores the ID of the WLAN device 110 and the ID of the WLAN access point 120 used in the world garden site, the list of Internet sites allowed to access to all users, and It is provided with a database (not shown) that stores a list of Internet sites accessible for each user, and stores reference values for instantaneous maximum traffic and cumulative traffic amount.

The controller 170 controls the overall operation of the service system including the world, such as the operation and user authentication of the WLAN access point 120, the authentication of the place where the user is connected, the authentication of the time the user is connected.

That is, the controller 170 controls the corresponding WLAN access points 120 to perform a handover function for the WLAN device 110 moving from one access point to another.

The controller 170 controls the operation of the switch 130. For example, if the user is not a registered user as a result of the user authentication or if the Internet site to which the user is connected is an Internet site that is not allowed to access, the controller 170 transmits a data packet transmitted by the corresponding WLAN device 110. The switch 130 is controlled to drop or forward to a connection limit screen displaying a connection restriction.

In addition, when performing user authentication, the controller 170 performs user authentication using an ID (for example, a MAC address) of the user's WLAN device 110. The ID of 110 is transmitted to the authentication server 150.

When performing user authentication through a user account, an initial authentication screen is provided to the WLAN device 110 so that a user can input a user ID and password, and the user ID and password input by the user are authenticated. Deliver to server 150.

As a result of user authentication of the authentication server 150, when the user accessing the world garden service is not a registered user, the controller 170 drops a data packet transmitted by the wireless LAN device 110 of the corresponding user ( Control the switch 130 so that the controller 170 may provide an access restriction screen indicating that access is restricted to the user's WLAN device 110.

The controller 170 may provide an initial application screen to the WLAN device 110 of the user when the user accessing the world garden service is a registered user as a result of user authentication of the authentication server 150. .

The initial application screen displays a list of Internet sites that all users can access, a list of personal registered Internet sites set by each user, and the like.

Here, the Internet site accessible to all the users includes the Internet site of the Internet service operator who paid the World Garden entry fee (a type of access fee) to the World Garden service provider.

In addition, the initial application screen may display a banner advertisement of an internet site of a sponsoring entity or a company applying for an advertisement for a predetermined price so that the World Garden service provider may provide a free Internet access service.

In addition, the initial application screen, the world garden service provider may display information related to the world garden site, the contents such as the content according to the operation of the world garden service, and the user's Internet connection usage status.

In addition, the controller 170 measures the amount of traffic transmitted and received for each user's wireless LAN device 110 or each Internet site that the user accesses, and transmits the traffic to the policy server 160. In this case, the controller 170 separately measures the amount of traffic transmitted and the amount of traffic received by the user's wireless LAN device 110 or each Internet site to which the user is connected, and also measures the instantaneous maximum traffic and the accumulated traffic to measure the policy. Transfer to server 160.

When the controller 170 determines that the access time of the user exceeds a preset time or the measured traffic amount exceeds the preset traffic amount, the controller 170 indicates that communication is limited. Provide a limited screen to the corresponding WLAN device 110.

In this case, the controller 170 controls the switch 130 to drop a data packet transmitted by the user's WLAN device 110 and a data packet destined for the user's WLAN device 110. do.

Meanwhile, as described above, the switch 130, the controller 170, the authentication server 150, and the policy server 160 may be implemented as individual devices to perform a corresponding function, but one controller ( It can also be implemented by performing all functions in the control means).

That is, when the size of the world garden site is small, one controller may be implemented to perform all the above functions. In this case, the operation according to each function may be performed within the controller (control means) rather than by communication between individual devices. It is made by the communication between the formed plurality of functional modules.

As such, the world garden service of the present invention provides a free Internet access service to a plurality of WLAN device users in a limited space called a world garden site, and may be referred to as a public WLAN service.

It is a free wireless Internet access service for many users of WLAN devices in public areas such as terminals, exhibition halls, shopping centers, and campuses. Will be given.

In particular, since it can be used by a large number of people of various ages and classes, it is necessary to block or control access to unhealthy sites such as adult Internet sites or gambling Internet sites or Internet sites that generate a large amount of traffic.

In addition, the World Garden Service Provider may provide differentiated access services between Internet sites in terms of policies for the construction and operation of a free wireless Internet system.

To this end, the world garden service of the present invention controls the wireless LAN Internet access centering on user authentication, access Internet site, access location, access time, traffic amount, and the like.

The world garden service of the present invention allows wireless LAN users to use the wireless Internet for free, and the cost for operating such a service is covered by an Internet service operator (ISO) or an advertiser.

2 is a flowchart illustrating an embodiment of a method for providing a world garden service according to the present invention.

Referring to FIG. 2, first, the controller 170 checks whether there is a connection request to a world garden service in the world garden site. In operation S100, users in the world garden site use the WLAN device 110. Check whether or not to connect to the world garden service of the present invention.

As a result of checking in step S 100, when there is a connection request to the world garden service, the authentication server 150 performs user authentication for the user who has made a connection request to the world garden service (S110).

Here, the user authentication may be a method of using a user account or a method of using a unique ID of the WLAN apparatus 110 of the user, and may be performed by mixing the two.

When using a user account, the controller 170 provides an initial authentication screen to the wireless LAN device 110 of the user, transfers the user ID and password input by the user to the authentication server 150, the authentication The server 150 performs user authentication by comparing the received user ID and password with the user ID and password stored in a database (not shown).

When using the unique ID of the WLAN device 110, the controller 170 extracts the MAC address of the WLAN device 110 from the data packet transmitted by the WLAN device 110 of the user and authenticates the authentication. The authentication server 150 compares the received MAC address with a MAC address stored in a database (not shown) to perform user authentication.

As a result of performing the user authentication in step S 110, when the user who has made a connection request to the world garden service is not a registered user, access of the wireless LAN apparatus 110 of the user is restricted (S 120).

That is, the controller 170 provides an access restriction screen for restricting access to the user's WLAN device 110 and switches 130 to drop a data packet transmitted by the WLAN device 110. To control.

As a result of performing the user authentication in step S 110, when the user who has made a connection request to the world garden service is a registered user, the policy server 160 determines a URL (Uniform Resource Locator) of the Internet site that the user wants to access. By checking, it is confirmed whether the Internet site is allowed to access (S 130).

That is, the policy server 160 determines whether to allow the Internet access by comparing the address of the Internet site to be accessed by the user with the address of the Internet site stored in a database (not shown).

The database (not shown) stores a list of Internet sites allowed to access to all users and a list of Internet sites accessible to each user.

As such, the Internet connection of the present invention is limited to an Internet site where the World Garden Service Provider allows access to all WLAN users, and an Internet site that is allowed by the World Garden Service Provider for each WLAN user.

Here, the Internet site that is allowed access to all the WLAN users is determined by the world garden service provider's own criteria. For example, the Internet site of the Internet service operator who paid the World Garden entry fee to the world garden service provider may be included, and a non-profit public interest site may be selected.

The Internet sites allowed by the World Garden Service Providers to be accessed by the respective WLAN users may be selected from the Internet Sites registered by each User within the limits of the World Garden Service Providers. Say.

As a result of checking in step S 130, when the Internet site to be accessed by the user is an Internet site that is not allowed to be accessed, the controller 170 restricts access of the user's WLAN device 110 (S 140). .

That is, the controller 170 provides an access restriction screen for restricting access to the user's WLAN device 110 and switches 130 to drop a data packet transmitted by the WLAN device 110. To control.

As a result of checking in step S 130, when the Internet site to be accessed by the user is an internet site to which the user is allowed to access, the controller 170 measures the access time of the WLAN device 110 to determine the policy server 160. To be delivered (S 150).

Next, the policy server 160 checks whether the access time of the WLAN device 110 exceeds a preset usage time limit (S 160).

The policy server 160 may limit the total usage time for each user in units of days, weeks, months, etc. In this case, the policy server 160 may measure the access time of the measured WLAN device 110. Check if the set usage time limit has been exceeded.

In this case, when checking whether the usage time limit is exceeded based on the day, the policy server 160 manages the place where the user is connected. For example, if the total time that can be accessed in one day is set to two hours and the continuous use time in one place is set to one hour, the user can also check the place where the user is connected and use it continuously for more than one hour at one place. Do not do it. That is, the measurement of the use time and the access control accordingly are made based on the place where the user is connected.

As a result of checking in step S 160, when the user exceeds a preset usage time limit, the controller 170 restricts a user's access to the wireless LAN apparatus 110 (S 170).

In this case, the controller 170 may transmit the access restriction screen indicating that the usage limit time has been exceeded to the user's WLAN device 110, and may transfer the access restriction screen to move to another place and use it. have.

Subsequently, the controller 170 measures the amount of traffic of each Internet site to which the WLAN device 110 or the user accesses and transmits the traffic amount to the policy server 160 (S 180).

At this time, the controller 170 measures the amount of traffic transmitted and the amount of traffic received by the wireless LAN device 110 of the user or each Internet site to which the user is connected, and transmits the received amount to the policy server 160. The maximum traffic and cumulative traffic amount are measured and transmitted to the policy server 160.

Next, the policy server 160 checks whether the traffic amount of each of the Internet sites that the WLAN device 110 or the user accesses exceeds the reference traffic amount (S 190).

That is, the policy server 160 checks whether the amount of traffic transmitted, the amount of traffic received, the instantaneous maximum traffic, the accumulated traffic, etc. of each of the Internet sites to which the WLAN device 110 or the user accesses exceeds the reference traffic amount. do.

As a result of checking in step S 190, when the wireless LAN device 110 or each Internet site to which the user accesses exceeds a reference traffic amount, the controller 170 restricts access of the wireless LAN device 110 of the user. (S 200). In this case, the controller 170 may transmit the access restriction screen indicating that the reference traffic amount has been exceeded to the user's WLAN device 110.

On the other hand, in this case, it is described as checking whether the usage timeout is exceeded first, and later checking whether the reference traffic amount is exceeded, but changing the order to check whether the reference traffic amount is exceeded, and then checking whether the usage timeout is exceeded. You may.

3 is a view schematically showing a public WLAN service network system using the world garden service system of the present invention. Here, as in the present invention, the World Garden Service Provider (WGSP) is provided with the Internet Service Operator (ISO) and the Internet Service Provider (ISP) in order to provide wireless Internet service to a plurality of WLAN device users at the World Garden site free of charge. The fee for use provided structure was shown.

Referring to FIG. 3, a plurality of WLAN device users 200 at a world garden site of the present invention may use a WLAN Internet access service provided by a World Garden Service Provider (WGSP) 300 free of charge.

You can connect to the Internet site that you allowed to access.

In this case, the traffic only passes through the WLAN infrastructure provided by the World Garden Service Provider 300, and the actual provision of the service and the corresponding charges occur between the WLAN device user 200 and the corresponding Internet site. .

The Internet Service Operator (ISO) 400, which operates Internet sites such as portals, finance, shopping, etc., to which the World Garden Service Provider 300 allows access, allows the World Garden Service Provider 300 to allow Internet access for free. In return, the world garden entry fee (some kind of access fee) or a portion of the revenue generated by the wireless Internet connection may be paid to the world garden service provider 300.

At this time, the world garden service provider 300 may allow free entry to a small-scale or non-profit public interest site according to its own criteria. In addition, the world garden service provider 300 may provide an advertisement service to the internet service operator 400 located in the world garden site while allowing internet access.

That is, the world garden service provider 300 may cover the service operation cost required to provide the wireless Internet service to the WLAN device user 200 free of charge from the Internet service operator 400 or a separate advertiser. As such, when the service operation cost is charged to the Internet service operator 400, the cost may be determined based on the number of access attempts to the corresponding Internet site operated by the Internet service operator 400, the amount of traffic exchanged, and the like.

Meanwhile, an Internet service provider (ISP) 500 operating a business by providing an internet access service may dispute that WLAN device users access the Internet for free.

However, the Internet service provider 500 may not generate a wire fee fee of the World Garden Service Provider 300 and access to the Internet site of the Internet Service Operator 400, which would not occur if the World Garden Service Provider 300 did not provide the World Garden Service. This can be recovered through additional line charges as traffic increases.

According to the present invention, the wireless LAN device user 200 may use the wireless Internet for free at the World Garden site, and may obtain necessary information or process a job through this.
