1 is a block diagram illustrating a network environment in which a wireless Internet service providing system in which a duplicate phone is blocked according to an embodiment of the present invention is implemented.

Referring to FIG. 1, a network environment in which the present invention is implemented may include a mobile communication terminal 200, a wireless communication network 300 for mediating wireless communication of the mobile communication terminal 200, and the wireless communication network 300. Wireless Internet service providing system for authenticating the mobile communication terminal 200 to be connected to block the duplicated phone and provide a paid data service, the Internet 310 and the data service server 320 connected to the system.

The mobile communication terminal 200 is in charge of basic call call processing and location registration functions, and voice call arrival and departure functions. In addition, the mobile communication terminal 200 performs data communication based on call arrival, outgoing calls and wireless Internet and data services through the wireless communication network 300. The mobile communication terminal 200 includes a cellular phone, a personal communication service (PCS) phone, a PDA phone, a GSM phone, a WCDMA phone, a CDMA-2000 phone, a DMB phone, and the like.

The wireless communication network 300 is a wireless communication access network providing a variety of access methods and a wireless portal gateway 140 for connecting a voice communication network for processing voice call calls and the external Internet 310 and data service server 320 and It includes a data communication network to be connected.

The Internet 310 is an internationally connected network structure that connects various service providers with users who use the service. In particular, the mobile portal terminal 200 may be connected to the mobile communication terminal 200 through the wireless portal gateway 140 connected to the wireless LAN or the wireless communication network 300.

The data service server 320 is connected through the wireless portal gateway 140 and provides various data services provided by respective communication companies.

Here, the wireless Internet service providing system according to an embodiment of the present invention is a wireless portal gateway 140, authentication management server 110, DRM (Digital Right Managment) server 120, download server 130, customer center 111, the terminal information management server 112 and the SMS server 113.

The wireless portal gateway 140 receives a wireless Internet and data service connection request from the mobile communication terminal 200 connected through the wireless communication network 300 and performs a function of connecting to the corresponding service after authentication.

The authentication management server 110 receives a formal user registration of a mobile communication subscriber subscribed to a mobile communication provider and is in charge of subscriber authentication processing at the data portal connection processing in the wireless portal gateway 140. In addition, upon receiving the registered user registration, the subscriber information is input and the subscriber information is determined by using the subscriber information. In the case of the registered subscriber, the public key is generated and stored by combining the corresponding values in the received subscriber information. The generated public key is provided to the corresponding subscriber station 200, and the public key and authentication management provided to the corresponding subscriber station 200 during authentication processing for data service and wireless Internet access at the wireless portal gateway 140. The public key stored in the server 110 is compared to determine whether the subscriber is a regular subscriber. In addition, at the time of receiving the formal user registration, a predetermined password determined by the subscriber is input and stored. Then, when the subscriber terminal 200 requests to provide the public key again, the process of comparing the received password with the password in addition to the formal subscriber check operation is further performed. This is to prevent the duplicated terminal from receiving a public key identified as a registered subscriber.

The subscriber information received during the formal user registration includes a subscriber resident number, a client telephone number (CTN), a terminal model number (ESN), and the like. Each of these subscriber information is used by the authentication management server 110 to confirm whether or not a regular user. The subscriber's social security number and the subscriber's telephone number confirm the identity of the subscriber. The customer's center 111 requests the social security number and the telephone number to receive the identity. In addition, the terminal information management server 112 is requested by the terminal model number to check whether the terminal of the subscriber. The user is registered through the verification, and if the information does not match with the user's information or is confirmed as a registered subscriber, the SMS server 113 informs the subscriber and the corresponding mobile communication. Notify the operator. In this case, the SMS server 113 sends an SMS to the duplication notification terminal preset by the subscriber. In addition, the SMS is sent with the location information of the terminal in case of a formal user registration error. By using this, the subscriber can determine whether a simple error or his terminal is duplicated and used by referring to his location.

The DRM server 120 grants and controls the right to read, write, change, delete, etc. the application. An application controlled by the DRM server 120 may not be arbitrarily changed, copied, or deleted. In addition, the DRM server 120 receives the instructions of the authentication management server 110 to grant and control the authority of the application.

The download server 130 stores an application used when the mobile communication terminal 200 accesses the wireless Internet and a data service. The stored application is authorized under the control of the DRM server 120 and downloaded to the mobile communication terminal 200. In addition, the downloaded application is inserted with the public key generated by the authentication management server 110 under the control of the DRM server 120, and downloaded to the terminal once the download authority is granted. Such an application may not be arbitrarily changed, deleted, or copied without authorization under the control of the DRM server 120. As a result, it is impossible to download or copy the application with the copy phone.

2 and 3, first of all, a mobile subscriber performs a formal user registration procedure in order to receive a wireless Internet service through a wireless Internet service providing system in which a copy phone of the present invention is blocked. To this end, mobile subscribers wishing to use paid services such as wireless internet and data services enter subscriber information through wireless sites or customer centers. The subscriber information includes a social security number, a subscriber's telephone number, a terminal model number, and the like, and may additionally receive a password determined by the subscriber. (Step S10).

Next, it is determined whether the subscriber is a regular subscriber using the subscriber information input in step S10. The determination of whether the subscriber is a subscriber is made based on whether or not the subscriber and the terminal of the subscriber is a normal terminal. The identity of the subscriber is determined based on the social security number and the subscriber's telephone number included in the subscription information through the customer center, and whether or not the normal terminal is determined based on the terminal model number through the terminal information management server. (Step S20)

If the determination result of the step S20 is confirmed as a full subscriber, the formal user registration procedure from step S40 is performed. In addition, if it is determined that the subscriber is not a regular subscriber, that is, the result of identity verification and terminal identification does not match or an error occurs, the official user is not permitted to register and reports an abnormal state (steps S30 and S45).

The abnormal status report is notified to the customer center and the subscriber by using the SMS. When notifying the subscriber, an SMS is sent to the duplication notification terminal preset by the subscriber (step S46).

If it is confirmed as a full user in step S30, it is registered as a full user and generates a public key by combining the values of the entered subscriber information. The generated public key is used for authentication of a subscriber registered as the authorized user, and for this purpose, the generated public key is stored in an authentication management server (step S40).

Next, the public key generated in step S40 is inserted into the copy protection application to be provided to the subscriber terminal. The copy protection application is provided to the subscriber station and used when comparing and determining the public key inserted during copy protection authentication of the subscriber station.

The copy protection application in which the public key corresponding to the subscriber is inserted grants one download right. In particular, the copy protection application cannot arbitrarily read, write, copy, change, delete, and the like. Therefore, the terminal can download the copy protection application only once, and after that, a separate procedure is required to download again. In addition, control such as authorization of the copy protection application may be performed only through the application DRM server. As a result, it is possible to copy the copy protection application to the illegal copying phone, thereby preventing a shortcut to be authenticated with the public key included therein (step S60).

The copy protection application thus authorized is downloaded to the subscriber terminal at the request of the subscriber only once. However, if it is necessary to download the application again after the one time download because of an update operation or terminal change due to the upgrade of the application, a separate procedure must be performed as described in step S60. The separate procedure receives a password additionally input in step S10 and a public key of the application downloaded to the subscriber terminal from the subscriber to download the application again. The password and the public key received in this way are compared with the password stored in the authentication management server through the public key, and if the match is granted once again, the right to download. In this way, the copy protection application to which the authorization is granted once is downloaded to the subscriber terminal. This is to prevent illegal copying of the terminal registered as a regular user and re-download the copy protection application to the copy phone. (Step S70).

As described above, the subscriber who has completed the formal user registration and downloaded the copy protection application to the terminal can use the wireless Internet and data services in the following procedure.

First, the subscriber accesses the wireless communication network through the terminal and requests access to the wireless Internet and data service. (Step S80).

In response to the access request, the authentication management server compares the public key included in the copy protection application of the subscriber terminal with the stored public key (step S90).

If the authentication result confirms that the user is authorized, the wireless Internet and data services are allowed to be accessed, and if authentication fails, the following step S120 is performed. (Steps S100 and S110).

If the authentication fails in step S100, the connection of the wireless Internet and data service is blocked, and the terminal attempting the connection is determined to be an abnormal terminal. (Step S120).

If it is determined that this is an abnormal terminal, it notifies the customer center and subscriber. At this time, the subscriber is also sent an SMS to the pre-set replication notification terminal. In addition, the SMS sent to the copy notification terminal may include the location information of the terminal that the authentication failed. This is the basis for determining whether the authentication failure is a simple error or illegal copying (step S130).

4 is a flowchart illustrating a procedure performed at each processing stage of a wireless Internet service providing system in which a duplicate phone is blocked according to an embodiment of the present invention.

Referring to FIG. 4, first, a procedure of inputting subscriber information for formal user registration from a subscriber to a copy protection authentication management server through a wireless site or a customer center is performed.

The copy protection authentication management server requests the terminal model number from among the received subscriber information to the terminal information management server to check whether the subscriber is a genuine terminal.

Next, the subscriber's social security number and subscriber's telephone number of the subscriber information received by requesting the customer center (rate information) to check whether the subscriber's identity. (3)

It is determined whether the subscriber is a regular user based on the results of steps 2 and 3. (4)

If it is determined that the user is not an authorized user, an error report is instructed to the SMS server, and the SMS server sends the fact to the customer center and the subscriber by SMS.

If it is determined as the authorized user as a result of step 4, the user registers as a authorized user and generates a public key by combining the values of the received subscriber information. In addition, the generated public key is stored and stored in the copy protection authentication management server.

In the copy protection authentication management server, the application DRM server sets an application DRM key value (application delete and write permission) as a public key, and instructs authorization of the corresponding application.

The application DRM server grants write and read permission of the application to the application download server according to the set key value.

The application download server inserts the public key of the corresponding subscriber created in the copy protection application and sets one download authority to the corresponding subscriber terminal according to the authority granted by the application DRM server.

At the request of the subscriber terminal, the corresponding copy protection application of the application download server is downloaded to the corresponding subscriber terminal only once.

The subscriber station that has downloaded the copy protection application and installed in the terminal requests wireless Internet access by accessing the wireless portal gateway according to the subscriber's wireless internet service request.

The wireless portal gateway receives a connection request and proceeds with authentication of the subscriber. In the subscriber's authentication, the public key included in the copy protection application installed in the subscriber's terminal is exchanged with the copy protection authentication management server and authenticated by comparing with the public key of the subscriber in storage.

The wireless portal gateway receives the authentication processing request result from the copy protection authentication management server to determine whether the wireless portal gateway is a legitimate user.

If it is determined that the user is not an authorized user due to the authentication failure, the wireless portal gateway blocks the access to the wireless Internet and data service of the subscriber terminal and reports this fact (error) to the SMS server.

On the other hand, if the authentication is successful and determined to be a legitimate user, the wireless portal gateway allows the subscriber terminal to access the wireless Internet and data services.

As such, when the mobile communication service provider provides paid content such as wireless Internet or data service, the service is provided only to the authorized user terminal that blocks the illegal copy phone that fails the formal user authentication and succeeds in the authentication.

The method of the present invention as described above may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The terms or words used in this specification and claims are not to be construed as being limited to their usual or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best describe their invention. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

The method and system for providing a wireless Internet service in which a duplicate phone according to the present invention is blocked are authenticated every time a request for access to a paid service is made after registering and confirming that a mobile user who wants to use a paid service such as wireless internet or data service is registered as a regular user. Through the process, it blocks the counterfeit phone and provides the effect of preventing abnormal use of the paid service.

In addition, the authentication procedure used to block the duplicated phone and the copy protection means installed in the terminal can be handled in software to block the duplicated phone more flexibly and more quickly, without the user or operator wasting unnecessary time and money. There is an effect that can effectively prevent duplicate phones.
