Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a communication network including a Bluetooth access point for communication network matching according to the present invention.

The wireless Bluetooth small network consists of a PC 101, a mobile terminal 102, and a Bluetooth access point (AP) 103.

Bluetooth access point (Bluetooth AP) 103 is a gateway for connecting a communication network with a PC or a mobile terminal equipped with Bluetooth, and connects up to seven data links and three voice calls. ASL (Asynchronous Digital Subscriber Line) by connecting voice and data link with ADSL Tranceiver Unit-Remote terminal end (ATU-R) (ie ADSL subscriber unit 104) 104 Voice is connected to the public switched telephone network (PSTN) 107 via the communication line 105 and the DSLAM 106, and the data is connected to the data network 108. Here, a device for multiplexing a plurality of ADSLs on a network side is referred to as a Digital Subscriber Line Access Multiplexer (DSLAM) (hereinafter, simply referred to as DSLAM).

In order for a subscriber to access services via the PC 101 or the mobile terminal 102 to the main communication network (PSTN, data network) 107, 108, it is necessary to know whether the subscriber is a person who can receive the services of the carrier. There is a need for a check (ie user authentication).

Only then can the Telecommunication Service Provider impose a telecommunication fee on the subscriber, and that subscriber can also pay the telecommunication fee exactly as it is used.

Therefore, when the Bluetooth AP 103 receives a connection request from the terminal (PC, mobile terminal) (101, 102), and sends the subscriber information to the network in a predetermined data format, the network can determine the service type based on the received subscriber information. have.

2 is a configuration diagram of an embodiment of a communication network when the connection target of the Bluetooth terminal according to the present invention is a data network.

When receiving a data network connection request from the terminals 101 and 102, the Bluetooth AP 103 receives a Bluetooth identification number (ID), a user identification number (ID), and a password from the terminals 101 and 102. Data is sent to the data network 108 which is a connection system.

When the data network 108 receives a connection request from the subscriber, the subscriber network sends the subscriber information to the authenticator 202 inside the authentication system 200 to receive information related to whether or not a service can be provided and the type thereof. Here, the authentication system 200 is an element of the network, the system is responsible for authentication when the subscriber is connected, the subscriber database (DB) is a database that stores the information of the subscriber, the authenticator 202 is a terminal in the authentication system It is a device that authenticates by comparing the information of the subscriber and the information in the subscriber DB.

The authenticator 202, which has been requested to authenticate the subscriber, searches the subscriber database 201, finds the corresponding information, and sends information related to the presence / absence and type of service to the data network 108.

If it is determined that the connection is required by the information of the authentication system 200 (i.e., authentication) based on the information of the authentication system 200, the data required for the Bluetooth AP 103 (various parameters-IP, DNS, Gateway, etc.) If the service is not possible (that is, not authenticated), and transmits the service unavailable code to the Bluetooth AP 103, the Bluetooth AP 103 and the terminal 101, 102 requesting access reasons To know.

3 is a configuration diagram of an embodiment of a communication network when a connection target of a Bluetooth terminal according to the present invention is a public telephone network / intelligence network.

When the terminal requests a connection by voice call, the Bluetooth AP 103 dials like a regular landline telephone. Here, the access exchange should have a function that can support the intelligent network service.

The PSTN internal access exchange 107 identifies that the subscriber is an intelligent network subscriber and requests the intelligent network 303 for call setup. The intelligent network switch 304 receiving the call setup request requests the intelligent network service information of the subscriber from the intelligent network service database (DB) 305. Here, the intelligent network 303 is a control signal network for the subscriber to provide a convenient service by extracting a control signal from the PSTN 107, the intelligent network switch 304 is a device for exchanging the path of the control signal in the intelligent network 303 The intelligent network service DB 305 represents a database storing subscriber information or service information in order to provide a service in the intelligent network 303.

The intelligent network service DB 305 grasps information that needs to interwork with the data network in order to obtain service information of the subscriber, and requests the subscriber information to the authentication system 300 of the data network.

The subscriber DB 301 of the authentication system 300 sends the subscriber's information to the intelligent network service DB 305, and the intelligent network service DB 305 transmits call setup information to the intelligent network switch 304.

The intelligent network switch 304 which receives the call setup information starts call setup, which is the same as the call setup procedure in a general landline telephone.

The above-described service process is a method for enabling the intelligent network service while minimizing the change in the existing exchange. The general exchange has only the information of whether or not the intelligent network service is subscribed to each subscriber, and it is determined that the intelligent network is a call.

In addition, in order to make the charging method more diverse, information such as user ID, password, etc. may be received as DTMF tones using an intelligent recording guide service generally attached to the intelligent network switch 304.

In order to reduce the data network access system load caused by illegal subscribers and wrong access subscriber calls, the Bluetooth AP 103 can remotely control the connection failure of a terminal having the same Bluetooth ID, user ID, and password. As a value that is, for example, 10 minutes, if a certain number of times (eg, a value that can be adjusted remotely by the main network operator, for example, 3 times) is repeated, a predetermined time (value that can be adjusted remotely by the main network operator), For example, 30 minutes).

In addition, the Bluetooth AP 103 stores a user's information (Bluetooth ID, User ID, Password) once successfully connected to the service in his DB, for a predetermined time (a value that can be adjusted remotely by the main network operator, For example, when a reconnection request comes in within 30 minutes, an attempt is made to connect to the connection request data network 108 in a format different from the new connection.

Users who have accessed the data network connection system once can save data in their own DB for a certain period of time and use it immediately.

Such a method is a method of reducing the load on the authentication system that may occur in connection with the truncation caused by the uniqueness of the wireless environment.

4 is a flowchart illustrating a method for accessing a communication network of a terminal through a Bluetooth access point for network matching according to the present invention.

The automatic user registration and communication network access procedure of the LAN / PSTN matching Bluetooth access point permits the network connection only to authorized terminals that have been authenticated by the communication network when attempting to connect to the data and voice Bluetooth wireless terminals. It's about how to do it.

First of all, the automatic registration of the user, user information registered in the central database of the network has a user ID and password, if only two registered, the terminal borrows a different user ID and password It is necessary to register the Bluetooth ID, which is the ID of the terminal itself.

The Bluetooth ID is the only unique ID in the Bluetooth module in the terminal device.

User ID, Password, and Bluetooth ID are required for authentic authentication of the user. The Bluetooth ID is a 48-bit hexa code, which the user directly enters. Is difficult, so a network or Bluetooth access point (AP) is required to automatically register.

When a user applies for subscription, only the User ID and Password are registered in the central database.

When the user uses the service for the first time, it recognizes that it is the first connection in the communication network and the Bluetooth AP obtains the Bluetooth ID by the interaction between the terminal and the Bluetooth AP, and sends the Bluetooth ID to the communication network to automatically transmit the Bluetooth ID to the database of the communication network. You will be registered.

Afterwards, the automatic ID registration is not performed, and the authentication is simply performed with a user ID, password, and Bluetooth ID.

Hereinafter, FIG. 4 will be described in detail.

When the user's Bluetooth terminal first attempts to connect to the communication network through the Bluetooth AP (401), the Bluetooth AP receives a Bluetooth identifier, a user identifier, a password from the user's Bluetooth terminal, and inputs the Bluetooth identifier input while requesting the network connection authentication to the communication network. The user identifier and password are transmitted together (402).

The authentication system of the communication network checks whether the user (subscriber) identifier and password stored in the subscriber database match the user identifier and password transmitted from the Bluetooth AP (403), and if so, registers the transmitted Bluetooth identifier in the subscriber database. Then, the network AP is notified of the permission to access the network, and if there is a mismatch (that is, at least one is different), the connection is not allowed (404).

The Bluetooth AP receives an authentication result (access permission / disallowed) from the authentication system of the communication network and transmits the authentication result to the user's Bluetooth terminal (405).

As a result of the authentication of the authentication system of the communication network to be connected, when authentication is successful (that is, when the connection is permitted), a call is established between the Bluetooth terminal and the communication network and communication is performed.

On the other hand, after the set call is released between the set Bluetooth terminal and the communication network, if there is a new connection attempt from the Bluetooth terminal to the Bluetooth AP (406), the Bluetooth AP receives a Bluetooth identifier, a user identifier, and a password from the Bluetooth terminal, The Bluetooth identifier, the user identifier, and the password are transmitted together with the connection authentication request (407).

The authentication system of the communication network checks whether the Bluetooth identifier, the user (subscriber) identifier, and the password stored in the subscriber database match the Bluetooth identifier, the user identifier, and the password transmitted from the Bluetooth AP (408). The AP notifies the network access permission, and if it does not match (that is, at least one is different) it notifies the access permission (409).

The Bluetooth AP receives an authentication result (access permission / disallowed) from the authentication system of the communication network and transfers the authentication result to the user's Bluetooth terminal (410).

As a result of the authentication of the authentication system of the communication network to be connected, when authentication is successful (that is, when the connection is permitted), a call is established between the Bluetooth terminal and the communication network and communication is performed.

As shown in FIG. 3, a public telephone network (PSTN), an intelligent network, and a data network are interworked with each other, and all authentication is performed in an authentication system of a data network.

Therefore, when the communication network requested for connection is a data network, a Bluetooth identifier, a user (subscriber) identifier, and a password required for user authentication are transmitted from the Bluetooth terminal to the authentication system of the data network through the Bluetooth access point.

On the other hand, if the communication network required to be connected is a public telephone network / intelligence network, a Bluetooth identifier, a user (subscriber) identifier, and a password are entered into the authentication system of the data network through a public telephone network connected to the Bluetooth access point and an intelligent network connected to the public telephone network. Delivered.

As described above, the method of the present invention 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.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

As described above, the present invention provides a service in connection with a central database (or a pre-certified local database) when a general user tries to access a high-speed network (xDSL, etc.) and a public switched telephone network (PSTN) using a Bluetooth small network. By checking the availability, it is possible to reduce unnecessary load on the Bluetooth network and to prevent miscalculations.

That is, according to the present invention, when a user automatically registers a LAN / PSTN matching Bluetooth access point and uses a network connection procedure, the user can access a communication network with a mobile terminal, thereby providing convenience for the user. By preventing traffic, it is possible to efficiently operate the network. Also, in terms of the operator, the user authentication can prevent high-paying cases in advance, thereby providing high-quality services.
