Wireless Internet service user information providing method and system {SYSTEM AND METHOD FOR PROVIDING INFORMATION ABOUT WIRELESS INTERNET SERVICE USER}

The present invention relates to a method and system for providing wireless Internet service user information. In particular, the present invention provides wireless Internet service user information that enables users to charge wireless Internet service fee even for users who illegally use the wireless Internet service by stealing another subscriber's subscriber number. It relates to a method and a system.

In general, the Internet refers to the world's largest computer communication network that originated from ARPANET. In other words, the Internet was founded in 1969 with the support of the US Department of Defense, the Alphanet (ARPANET), which was established to connect four universities in the United States, and was initially built for military purposes, but adopted TCP / IP as a protocol, Separated into military MILNETs, it laid the foundation for the current Internet environment.

Services available on the Internet include e-mail, remote computer connection (telnet), file transfer (FTP), Usenet News, Internet information search (Gopher), Internet conversation and discussion (IRC). , Electronic bulletin boards (BBS), hypertext information viewing (WWW: World Wide Web), online games, etc., and new services such as video conferencing and video conferencing are being developed in turn.

In the past, the Internet could only be used by connecting a telephone line to a personal computer equipped with a modem. However, various methods for accessing the Internet have been developed. In addition to the conventional personal computers, devices capable of using the Internet are also available. The mobile communication terminal and personal digital assistant (PDA) have been diversified.

The subscriber information providing apparatus may be a network interworking apparatus (IWF), a packet data serving node (PDSN), or the like.

In the present specification, a subscriber number (NET_MIN) applied when a user terminal (for example, a mobile communication terminal, a personal digital assistant (PDA), etc.) and a mobile communication service system are connected to use a wireless Internet service is connected to a wireless subscriber. The subscriber number APP_MIN transmitted to the service provider server while using the Internet service will be referred to as a service subscriber number.

The access subscriber number NET_MIN and the service subscriber number APP_MIN are briefly described as follows.

First, the access subscriber number (NET_MIN) is a CDMA wireless access standard (e.g., IS-95A, IS-95B, etc.) transmitted by a user terminal in a mobile communication network to access a voice and / or data call. CDMA2000 1x, etc.) means identifier information called MIN (Mobile Identification Number) included in the message.

The access subscriber number (NET_MIN) generally corresponds to telephone number information and is inputted when a mobile communication service is subscribed through a user interface (UI) that is not visible to the subscriber in the user terminal.

The mobile communication service system (specifically, a specific network device in the mobile communication service system) receiving the access subscriber number NET_MIN identifies the subscriber that is the user of the user terminal 110 by using the access subscriber number NET_MIN. If it is determined that the subscriber is a normal subscriber, the subscriber is connected to the user terminal.

As a method of determining whether the corresponding subscriber is a normal subscriber using the access subscriber number (NET_MIN), a method using a terminal serial number (ESN: Electronic Serial Number) held by the mobile communication service system together with the access subscriber number (NET_MIN) There is this.

The terminal serial number (ESN) is a home location register (HLR) and AAA (Authentication, Authorization &) in the mobile communication service system along with the access subscriber number (NET_MIN) when the mobile communication service is subscribed (ie, when the mobile communication terminal is opened). Accounting) server. The mobile communication service system, in the case of a voice call connection request, access subscribers registered in the access subscriber number (NET_MIN), the terminal serial number (ESN), and the home location register (HLR) received from the user terminal. The subscriber is authenticated by checking whether the number NET_MIN and the terminal serial number ESN match.

In addition, in the case of a data call connection request, the mobile communication service system includes an access subscriber number (NET_MIN), a terminal serial number (ESN) received from a user terminal, an access subscriber number (NET_MIN) stored in an AAA server, and a terminal serial number ( The subscriber is authenticated by checking the correspondence of the ESN).

However, the service subscriber number (APP_MIN) means a subscriber number that allows the service provider corresponding to the application installed in the user terminal to check who the subscriber is. For example, mobile communication terminals are equipped with applications that can perform MagicN Service, Multipack Service, Video On Demand Service, and the like. Therefore, the applications are variously loaded.

These application programs are programs that are run in the user terminal after a call connection is established between the user terminal and the mobile communication service system. Therefore, when the user of the wireless Internet service runs a specific application program and accesses the service provider server, the service is provided. The provider server needs information about who the subscriber is in order to charge a fee for using the wireless Internet service.

In the conventional Internet service, a specific user accesses a web server, and then inputs his ID and password to perform authentication, thereby informing the web server of who is currently attempting to connect.

However, since there is no separate login procedure in the mobile communication network, the service subscriber number (APP_MIN) is transmitted to the service provider server to inform who has connected to the service provider server. Then, the service provider server checks whether the service subscriber number (APP_MIN) received from the user terminal is a normal service subscriber number (APP_MIN) (for example, a valid phone number form), and then the service subscriber number (APP_MIN) You will be charged. Therefore, it is necessary to include the service subscriber number (APP_MIN) in the application program accessing the service provider server among the application programs mounted on the user terminal. The reason why the access subscriber number NET_MIN and the service subscriber number APP_MIN are distinguished and used in the mobile communication network access process and the authentication process for using the wireless Internet service will be described later with reference to FIG. 1.

First, in describing the method and system for providing wireless Internet service user information according to the present invention, a wireless internet service user authentication method according to the prior art will be briefly described for convenience of understanding.

1 is a CDMA wireless Internet protocol hierarchy diagram.

Referring to FIG. 1, a wireless internet protocol of a user terminal 110 (eg, a mobile communication terminal, a personal digital assistant (PDA), etc.) is generally a wireless network layer, a point-to-point protocol (PPP), TCP / IP (Transmission Control Protocol / Internet Protocol), User Datagram Protocol (UDP), and application service layer. The wireless network layer is a mobile communication service system for transmitting and receiving data to and from the service provider server 130 through a mobile communication network. 120) and a layer for performing call setup and transmitting PPP layer information. In this layer, call setup can be made only when it is determined that the access subscriber number NET_MIN of the user terminal 110 is valid through the CDMA authentication scheme. Therefore, when call setup is made, the access subscriber number NET_MIN included in this layer can be said to be valid information.

Point-to-Point Protocol (PPP) is a protocol used to support not only the transmission of IP packets but also multiple protocols over one link.

TCP (Transmission Control Protocol) is a protocol that solves data loss, duplication, error, etc. and corrects the order of data. IP (Internet Protocol) performs host addressing and packet fragmentation. It is a protocol for. In addition, UDP (User Datagram Protocol) is a protocol for performing data transmission only in a predetermined direction. The application service layer is a wireless Internet service user after the user terminal 110 and the service provider server 130 are combined through a mobile communication network. The service subscriber number APP_MIN is transmitted and received between the user terminal 110 and the service provider server 130 in order to be charged for the service. The service provider server 130 may be any server on the Internet, and is generally divided into a service provider server to which a subscriber or a mobile communication service provider is trusted and a service provider server that is not.

Mobile communication service system 120 (specifically, Interworking Function (IWF), Packet Data Serving Node (PDSN, etc.) that connects user terminal 110 to the Internet) is generally PPP. The IP layer data included in the layer is transmitted to the service provider server 130 through the data network, or the IP data received from the service provider server 130 is loaded on the PPP layer to the user terminal. If necessary, the mobile communication service system 120 may analyze the Internet Protocol (IP) or Transmission Control Protocol (TCP) layer. When the user terminal 110 is connected to the Internet by a mobile communication network, the user terminal 110 may be analyzed. Information required by the application program is included in the TCP or UDP message and transmitted to the service provider server 130.

In some cases, since the service provider server 130 needs to perform charging, there is no way to transfer the access subscriber number (NET_MIN) of the wireless network layer to the service provider server 130 due to the characteristics of the Internet protocol. Service subscriber number (APP_MIN) is transmitted to enable the identification of subscribers.

2 is a diagram illustrating a method for providing wireless Internet service user information according to the prior art.

Referring to FIG. 2, in operation 210, the user terminal 110 receives a wireless internet service access request from a user. For example, a user may input a wireless internet access request by selecting a wireless internet access button provided in the user terminal 110, or select to access a specific service provider server 130 among a plurality of service provider servers 130. By inputting a button, an access request to the corresponding service provider server 130 may be input, and as a result, the corresponding application is executed.

In operation 210, the user terminal 110 transmits a call setup request to the mobile communication service system 120 through a communication network. The mobile communication service system 120 includes a base transceiver system (BTS), a base station controller (BSC), a mobile switching center (MSC), an interworking device (IWF), an intelligent network system. It is composed of various detailed devices such as (WISE: Wireless Information System Environment), but each function or feature is well-known facts. Here, the description and the operation of each device are not performed. The operation made in step 120 will be collectively described.

 In step 230, the mobile communication service system 120 checks whether the call establishment request received through step 220 is valid information. The call setup request transmitted to the mobile communication service system 120 through step 220 includes an access subscriber number NET_MIN and / or a terminal serial number ESN stored in the user terminal 110. 120 checks whether the received information matches the access subscriber number NET_MIN and / or the terminal serial number ESN stored in the AAA server.

As a result of the check in step 230, if the call setup information is not valid information, the process proceeds to step 240 and transmits an error message to the user terminal 110 through the communication network. However, if the call setup information is valid information, the process proceeds to step 250 and the PPP session is established through the allocated wireless channel with the user terminal 110. Therefore, if the PPP session is established between the user terminal 110 and the mobile communication service system 120 through step 250, the access subscriber number NET_MIN received by the mobile communication service system 120 through step 220 is trusted. Information that can be.

The user terminal 110 connected to the Internet transmits a connection request to the service provider server 130 selected by the user in step 260, and the service provider server 130 connects to the user terminal 110 through a communication network in step 270. Do this. Of course, if a PPP session is established between the user terminal 110 and the mobile communication service system 120 through steps 210 to 250, the corresponding service provider server 130 and the user terminal 110 are automatically connected through a communication network. If connected, steps 260 to 270 may be omitted.

In operation 280, the application program installed in the user terminal 110 transmits / receives necessary application service data to the service provider server 130 via the mobile communication service system 120 through an allocated PPP session. If necessary, the application program of the user terminal may include the service subscriber number APP_MIN in the application service data and transmit the service subscriber number 130 to the service provider server 130.

Thereafter, the service provider server 130 generates billing data for the user terminal 110 using the service subscriber number APP_MIN received from the user terminal 110 (that is, charges for the wireless data service user are generated. Through the above-described method, the service provider server 130 may manage the fee for using the wireless Internet service.

In the case of legally using the wireless Internet service using the normal user terminal 110, the access subscriber number NET_MIN and the service subscriber number APP_MIN are generally the same. That is, when using normal services such as MagicN or Multipack using only the user terminal 110 that can use the wireless Internet service, the access subscriber number NET_MIN and the service subscriber number APP_MIN The same applies. However, in the case of the user terminal 110 such as a mobile communication terminal, the wireless Internet service can be provided in the following two modes.

First, it is a case of using a wireless Internet service by accessing a MagicN service or a multipack service by driving an application program installed in the user terminal 110 itself.

Secondly, the user terminal 110 operates as a modem and all applications run on an external device such as a notebook computer. In other words, after connecting the user terminal 110 and a notebook computer with a data cable, the user accesses a desired website and uses a wireless Internet service.

In the first method described above, the access subscriber number NET_MIN and the service subscriber number APP_MIN remain the same. In the second method, the access subscriber number NET_MIN and the service subscriber number APP_MIN may be applied differently. have.

This is because the access subscriber number NET_MIN is held by the user terminal 110, but the service subscriber number APP_MIN is inserted (or set) in the application, and thus is inserted (or set) in the application running on the notebook computer. Because there is. At this time, the application program running on the notebook computer, etc. may be about the emulation (emulator) of the application program mounted on the user terminal (110).

And, it is well known that a person who can do only a little programming can easily change the service subscriber number APP_MIN set in the application of the notebook to another person's number.

Therefore, after renewing the service subscriber number (APP_MIN) inserted in the application of their own to the service subscriber number (APP_MIN) of the dissatisfied person, if the information usage fee is provided with expensive service, the person may be charged the information usage fee. It could be. Of course, since the user connected to his access subscriber number NET_MIN at the time of wireless Internet access, the network usage fee will be charged to the user.

This problem has a limitation that cannot be solved in the conventional wireless Internet service user authentication method.

Hereinafter, a method for solving the above-mentioned problem will be described in detail with reference to the accompanying drawings.

3 is a diagram illustrating a schematic configuration of an apparatus for providing an access subscriber number NET_MIN to a service provider server according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the access subscriber number providing apparatus 305 according to the present invention includes an access subscriber number extractor 310, an access subscriber number encryption unit 320, a hash function value generator 330, and a result data insertion unit. 340. Of course, the access subscriber number providing device 305 is installed in an existing device (eg, a switching center (MSC), a network interworking device (IWF), a packet data serving node (PDSN), etc.) in the mobile communication service system 120. It may be implemented in the form of an application program capable of performing the functions of the respective means shown in FIG. In addition, it is obvious that the apparatus for providing access subscriber number 305 may be implemented as a device or an application that includes only some means without all the means shown in FIG. 3 (see the description of FIG. 4 and FIG. 5). ).

The access subscriber number extractor 310 establishes a PPP session between the mobile communication service system 120 and the user terminal 110, and then transmits to the service provider server 130 connected to the user terminal 110. A function of extracting the access subscriber number NET_MIN of 110 is performed. The access subscriber number NET_MIN may be obtained in the process of establishing a PPP session between the mobile communication service system 120 and the user terminal 110. The access subscriber number encryption unit 320 is connected to the access subscriber number extraction unit 310. It performs a function of encrypting the access subscriber number extracted by the. There is no restriction on the method of encrypting the access subscriber number.

The hash function value generation unit 330 generates a hash function value S by using the hash function F () through the access subscriber number NET_MIN and a constant value. The constant value may be shared between the mobile communication service system 120 and the service provider server 130 to determine whether the service subscriber number APP_MIN received from the user terminal 110 is valid at the service provider server 130. Will be.

The result data insertion unit 340 is a result value obtained by the access subscriber number extraction unit 310, access subscriber number encryption unit 320 or hash function value generator 330 (i.e., access subscriber number NET_MIN), encryption Inserts the access subscriber number (NET_MIN_e) or the hash function value into the service request data transmitted from the user terminal 110 to the service provider server 130.

4 is a data flow diagram illustrating a process of transmitting an access subscriber number in order to enable a service provider server to charge a wireless Internet service user according to an exemplary embodiment of the present invention.

In the description of the method of transmitting the access subscriber number with reference to FIG. 4, the description of the same steps 210 to 250 as described above with reference to FIG. 2 will be omitted.

Referring to FIG. 4, a user terminal 110 having a PPP session set up receives a service provision request for a service provided by a specific service provider server 130 from a user, and in step 410, the service provision request is transmitted through a communication network. The mobile communication service system 120.

In operation 420, the mobile communication service system 120 requests the service provision request for the access subscriber number NET_MIN corresponding to the user terminal 110 or the access subscriber number NET_MIN_e encrypted by the access subscriber number encryption unit 320. Insert in. In more detail, the subject inserting the information may be a network interworking device (IWF) or a packet data serving node (PDSN) included in the mobile communication service system 120. In this case, the access subscriber number NET_MIN may be a user terminal (eg It may be inserted using an extension protocol that does not affect the TCP / IP communication or the TCP / IP protocol between 110 and the service provider server 130. In this case, an authentication header (AH) of Internet Protocol Security protocol (IPSec) may be used. IPSec is a security standard in the packet processing layer of a network or network communication. It is characterized in that security preparation can be handled without changing individual user terminals. In addition, IPSec provides two types of security services: an authentication header (AH), which essentially allows authentication of a data sender, and an encapsulating security payload (ESP), which supports authentication and data encryption of a sender.

In addition to the above-described method, an overhead area that does not affect TCP / IP communication may be used.

If there is a relay system such as a proxy in the intermediate path between the mobile communication service system 120 and the service provider server 130, the access subscriber number NET_MIN is also relayed.

The mobile communication service system 120 transmits a service providing request in which the access subscriber number NET_MIN or the encrypted access subscriber number NET_MIN is inserted to the service provider server 130 through the communication network in step 430.

The service provider server 130 transmits the service data corresponding to the service provision request to the user terminal 110 in step 440. The process proceeds to step 450 by using the access subscriber number NET_MIN received in step 420. Generate billing data for Internet service usage. However, if the encrypted access subscriber number NET_MIN_e is received in step 420, the service provider server 130 may further perform a process of generating the access subscriber number NET_MIN through decryption.

5 is a data flow diagram illustrating a method of using a hash function value to enable a service provider server to charge a wireless Internet service user according to another embodiment of the present invention.

The hash function applied to the present invention will be briefly described as follows.

In general, a hash function is a function that receives a message having an arbitrary length as an input and expresses a bit of a certain length. The hash function is used for message authentication or digital signature. If the original message X is the result of using the hash function f (that is, the hash function value) as S, then f (X) = S.

In order to be a safe hash function, first, a message of arbitrary length must be received as input, second, a fixed length output must be produced, and third, f (X) of all Xs must be easy to calculate, Fourth, the original X cannot be obtained using the hash function value S. Fifth, it is difficult to obtain X and Y having the same hash function value S as f (X) and f (Y).

Types of hash functions include MD4, MD5, and SHA (Secure Hash Algorithm). Using MD4 and MD5, 128-bit hash function values are used, and using SHA (Secure Hash Algorithm), 160-bit hash functions. The value is generated.

In the description of the method for transmitting the access subscriber number with reference to FIG. 5, the description of the same steps 210 to 250 as described above with reference to FIG. 2 will be omitted.

Referring to FIG. 5, a user terminal 110 having a PPP session set up receives a service providing request for a service provided by a specific service provider server 130 from a user, and in step 510, a service providing request through a communication network. The mobile communication service system 120. The service providing request transmitted from the user terminal 110 may include a service subscriber number (APP_MIN) inserted into an application program driven in the user terminal 110.

In step 520, the mobile communication service system 120 uses the hash function F (NET_MIN, x) through the access subscriber number NET_MIN and the constant value x obtained in step 220, to determine the first hash function value S. Create The constant value x may be a value shared in advance between the mobile communication service system 120 and the service provider server 130 or may be transmitted to the service provider server 130 along with a hash function value.
