The present invention relates to a method for enhancing security and charging according to a wireless Internet access in a one-phone service supporting a mobile communication mode and a wireless telephone using Bluetooth in one terminal.                         

Bluetooth is a small, low cost, low power consumption wireless connection within the base station (10m to 100m), network access points, and other peripherals such as mobile devices such as mobile phones and portable PCs. It is a technology that is in the spotlight as a local area network as a technical standard for the.

Bluetooth adopts Bluetooth transmission method using 2.4GHz band of Industrial, Scientific, Medical (ISM) band. The 80MHz wide frequency is commonly assigned to the band worldwide, and is freely available to anyone without government approval. This band suppresses mutual interference by limiting the size of the transmission output to 100 kHz or 1 kHz for sharing by multiple users. The basis of Bluetooth is packet communication, but both data and voice communication are possible. By connecting two devices one-to-one, one-way data transfer can be up to 721kbps. In Bluetooth, up to eight devices come together to form a single network called a piconet, which allocates the entire capacity as appropriate between devices.

In addition, several independent piconets can be overlapped in the same space, so that they can be applied to places with high density of information processing and communication devices. Other features include transmission error correction, identity verification, passwords and power saving features.

Due to the advantages of the above-mentioned Bluetooth, the leading field of the application of Bluetooth is the application of the mobile phone. Among these applications, there are two phones (two in one-phone or three in one-pohne) which can use mobile communication and wireless telephone function using wired network. Ericsson, Nokia, etc. have already produced the one-phone terminal. . The one phone integrates a CDMA module and a Bluetooth module into one terminal, and the Bluetooth module performs Bluetooth communication with a Bluetooth access point, which is a connection point of an external network such as a PSTN or an XDSL. Therefore, the one-phone user can make a call by making a call using a wired network in the Bluetooth area, thereby making it possible to make a call at a low rate while ensuring its mobility.

1 is a schematic diagram illustrating an entire system for the aforementioned one-phone service.

The one-phone terminal 100 having the CDMA mobile communication and the Bluetooth function can be used as a normal mobile communication terminal outside the Bluetooth region 10. When the Bluetooth terminal 100 enters the Bluetooth region 100, it is automatically or manually switched to the Bluetooth mode. To perform wireless communication with the Bluetooth access point 200. At this time, the outgoing signal of the one-phone terminal 100 is directed to the wired network through the Bluetooth access point. The call is transmitted to the called party 60 through the wired network 30 or the mobile telephone network 40 according to the called party's environment. In addition, it is possible to use a variety of additional services using the intelligent network 50 according to the designation of the sender and the called party.

That is, the Bluetooth mode of the one-phone service performs the same operation as using a normal wired network except for performing Bluetooth communication between the Bluetooth access point and the one-phone. Accordingly, the charge of the wired telephone network can be applied.

Therefore, the one-phone service can provide data service for each of the mobile communication mode and the Bluetooth mode. Data communication in mobile communication is usually charged according to the packet and its cost is not small because it uses radio resources. On the other hand, data communication in a wired network is usually paid for by an ISP, so the connection is relatively free and low cost is required.

On the other hand, since the one-phone terminal has a mobile communication function, its mobility must be guaranteed, but it must be able to perform economic wired data communication within Bluetooth coverage. Therefore, when the one-phone terminal is within the Bluetooth coverage, a technique for automatically performing data communication using a wired network and performing charging accordingly is required for the operation of the one-phone terminal.

However, the related art does not present specific techniques and solutions for the case where the one-phone terminal performs data communication and billing thereof.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

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

2 is a schematic diagram showing a charging system for one-phone data communication according to a first embodiment of the present invention.

The one-phone terminal 100 in the present invention may be connected to a normal mobile communication network outside the coverage of the one-phone AP 200 to use a wireless Internet service. Such data communication for mobile communication may use a WAP architecture. Internet service providers (ISPs) can use a web server and WAP proxy server to deliver content to mobile devices over a wireless network. Mobile service providers can send data directly to WAP clients using a wireless telephone application (WTA) server. It may be.

On the other hand, as in the conventional mobile communication terminal, the one-phone terminal is provided with a hot-key for performing a wireless Internet connection, and by pressing the hot key, a connection for the wireless Internet is performed. However, since the one-phone has a mobile communication mode and a Bluetooth mode at the same time, when the one-phone terminal is in the Bluetooth coverage, the hotkey requests the wireless access point to access the wireless Internet service using the wired network to the Bluetooth access point.

When a wireless Internet service connection is requested using the wired network, the one-phone terminal 100 performs a PPP (Point to Point Protocol) setting with the one-phone AP 200. When the negotiation about authentication between the one-phone terminal 100 and the one-phone AP 200 is completed in the PPP setting, the AAA (Authentication, Authorization, Accounting) server 300 transmits an access request for authentication and billing.

If authentication is successful for the terminal, the AP 200 transmits an IP address to the terminal through the PPP link.

According to the system of the present invention shown in FIG. 2, the one-phone terminal 100 can use a wireless Internet service through a wired network using a public hotkey within Bluetooth coverage, and the billing according to the data communication is based on the pay-as-you-go or flat fee of the wired network. Will follow.                     

3 is a block diagram showing the structure of a one-phone terminal used in the authentication and billing system according to a first embodiment of the present invention.

The one-phone terminal used in the embodiment of the present invention includes a CDMA module 110, a Bluetooth module 120, a mode determining unit 130 and a hot key 140 for data communication. Although not shown in FIG. 3, the one-phone terminal includes a mode switching unit, a base band, an intermediate frequency, and an RF module for one-phone service.

The CDMA module 110 and the Bluetooth module 120 perform appropriate communication in the CDMA mode and the Bluetooth mode, respectively. The mode determination unit 130 sets the data communication mode of the hotkey 140 for data communication by referring to the activation states of the CDMA module 110 and the Bluetooth module 120.

Therefore, when the hot key 140 is pressed, the terminal starts data communication in accordance with the mode state determined by the mode determination unit 130.

Since the one-phone terminal performs voice communication in two modes according to the communication environment, such mode determination and switching can be applied to data communication as it is, and thus the specific operation thereof is obvious to those skilled in the art.

As such, according to the first exemplary embodiment of the present invention, the user of the one-phone terminal 100 may use a wireless Internet service using a wired network which is cheaper than a mobile communication network and excellent in speed.

However, in the current one-phone system, when the one-phone terminal 100 attempts to access the wireless Internet within the Bluetooth coverage, a wireless Internet service portal for only the one-phone terminal 100 is provided through the wired network. This has the advantage of providing a limited service only for the user of the one-phone terminal 100, but the kind of provided wireless Internet content is limited and its profitability is low, and there is a problem in activating the wireless Internet service using the one-phone terminal. In addition, according to the first embodiment of the present invention, there is a problem of overlapping investment in that it is necessary to construct its own wireless Internet platform for only one-phone terminal user, apart from the wireless Internet platform provided by the existing mobile communication company.

Accordingly, the second embodiment of the present invention solves this problem and the billing method and system of the one-phone terminal that can use a variety of content at low cost by connecting to the wireless Internet platform of the mobile communication network through a wired network in Bluetooth coverage It will be described in detail with reference to.

4 is a schematic diagram showing a charging system for one-phone data communication according to a second embodiment of the present invention.

The one-phone terminal 100 according to the second embodiment of the present invention also has a hot-key for a wireless Internet connection like the one-phone terminal 100 according to the first embodiment of the present invention. By pressing the connection for the wireless Internet is performed.

Therefore, when the one-phone terminal 100 belongs to the Bluetooth coverage, the hotkey requests the one-phone AP 200 to access the wireless Internet using a wired network.

When the wireless Internet connection is requested, the one-phone terminal 100 performs a Point to Point Protocol (PPP) setting with the one-phone AP 200. When the negotiation about the authentication between the one-phone terminal 100 and the one-phone AP 200 is completed in the PPP configuration, the AAA (Authentication, Authorization, Accounting) server 300 transmits an access request for authentication.

If the authentication for the terminal 100 is successful, the one-phone AP 200 transmits an IP address to the terminal 100 through the PPP link.

Next, the one-phone AP 200 obtains the IP address of the gateway 450 of the mobile communication network through the DNS server 310.

The one-phone AP 200 that obtains the IP address of the gateway 450 of the mobile communication network requests an IPSec-VPN tunnel configuration from the gateway 450 corresponding to the IP address.

The gateway 450 constructs an IPSec-VPN tunnel with the one-phone AP 200 according to general IP tunneling and IPSec standard protocols, and the authentication / billing server 410 attempts to access the wireless Internet. Authentication is performed using In addition, the gateway 450 allocates the IP address of the mobile communication network to the one-phone AP 100.

The one-phone AP 200 converts an IP address of the one-phone terminal 100 into an IP address of the mobile communication network allocated from the gateway 450, and performs network address port translation (NAPT) for authentication / billing server of the mobile communication network. In step 410, network address translation information is transmitted.

In this case, the network address translation information is mapped to the electronic phone number (ESN) and the mobile phone number of the one-phone terminal 100 and transmitted together at the end of the wireless Internet session or in real time to the authentication / billing server 410 of the mobile communication network. Can be sent.                     

The authentication / billing server 410 stores the network address translation information in a DB and utilizes the pay-as-you-go charging information for the one-phone terminal 100.

As described above, according to the second embodiment of the present invention, an IPSec-VPN tunnel is formed between the one-phone AP 100 and the gateway 450 of the mobile communication company to enhance communication security, and through the NAPT management of the one-phone AP, Pay-as-you-go billing will be possible with the use of the wireless Internet platform.

5 is a flowchart illustrating a Bluetooth authentication method according to a second embodiment of the present invention.

When the data communication (wireless Internet connection) is initiated through the hotkey of the one-phone terminal in step S100, the one-phone terminal determines which communication mode is activated through an internal mode determination unit.

When the mode of the one-phone terminal is a mobile communication mode using CDMA, the one-phone terminal provides data communication using a WAP client or a web server, and performs normal packet-based charging.

When it is determined in step S100 that the Bluetooth mode, in step S110, the one-phone terminal 100 and the one-phone AP 200 establishes a PPP link. When establishing the PPP link, the one-phone AP 200 negotiates authentication with the terminal 100 by a link control protocol (LCP), and transmits a challenge value to the terminal 100.

At this time, the one-phone terminal 100 transmits a response to the challenge value together with its ID to the one-phone AP 200 again.                     

When the one-phone AP 200 receives the terminal ID and the response, the one-phone AP 200 transmits it to the AAA server 310 of the network with the challenge value generated in the Radius message.

When the AAA server 300 receives the Radius message, the AAA server 300 performs authentication thereof. If the authentication is successful, the AAA server 300 transmits a Radius authentication success message to the one-phone AP (200).

At this time, the one-phone AP 200 receiving the authentication success message allocates an IP address through a PPP procedure with the one-phone terminal 100.

In the remote authentication, when a remote user requests a connection, information such as a terminal ID, a password, and an IP address is sent to the AAA server to identify and authenticate the user. The password generator and the authentication server synchronize each time to change the password. It can also be performed in a time-synchronous manner or a challenge-response method that encrypts a server-generated random number and superimposes it on a password.

Next, in step S120, the one-phone AP 200 obtains the IP address of the gateway 450 of the mobile communication network through the DNS server 310.

In step S130, when the one-phone AP 200 transmits an IPSec-VPN tunnel configuration request message to the gateway 450 corresponding to the IP address, the authentication / billing server 410 transfers from the gateway 450. The one-phone terminal 100 is authenticated using the information of the one-phone terminal 100 connected to the one-phone AP 200 (S140). When the authentication is completed, the gateway 450 establishes an IPSec-VPN tunnel with the one-phone AP 200 and assigns an IP address of the mobile communication network to the one-phone AP 200 (S150).

As described above, the one-phone terminal 100 may perform data communication by accessing the wireless Internet portal of the mobile communication network through the IPSec-VPN tunnel formed between the one-phone AP 200 and the gateway 450 (S160).

The one-phone AP 200 converts an IP address assigned to the one-phone terminal 100 into an IP address of the mobile communication network while the wireless Internet session with the mobile communication network continues or after the session is terminated. The information and the information (ESN and mobile phone number) of the one-phone terminal 100 is transmitted to the authentication / billing server 410 together (S170).

The authentication / billing server 410 performs a pay-as-you-go bill for the one-phone terminal 100 using the network address translation information and the terminal information (S180).

Meanwhile, when a plurality of one-phone terminals 100 are connected to the one-phone AP 200, and the plurality of one-phone terminals 100 attempts to access the wireless Internet, the one-phone AP 200 uses different ports for the corresponding terminals. It performs NAPT by assigning, and manages by mapping private IP (local IP), mobile operator private IP, port, ESN and mobile number corresponding to each terminal.

According to an embodiment of the present invention, the one-phone terminal performs data communication using a mobile communication network outside of Bluetooth coverage, but performs data communication using a wired network without additional manipulation within Bluetooth coverage.

Therefore, if a data communication infrastructure using a wired network has already been established in the home, the owner of the one-phone terminal may use data communication at a lower cost than the mobile communication without any additional cost.

In addition, in the Bluetooth mode, it is possible to perform data communication relatively faster than in the mobile communication mode, which is integrated in the wired network to which the Bluetooth point is linked.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the invention defined in the following claims are also provided. It belongs to the scope of rights.

As described above, according to the present invention, the data communication using the one-phone terminal can be used in a Bluetooth mode without any additional operation by connecting to a wired network at low cost and at a high data rate. In addition, a wireless Internet platform constructed in a mobile communication network can be used through an IPSec-VPN tunnel formed between the one-phone AP to which the one-phone terminal is connected and the gateway of the mobile communication network, and at this time, a security problem according to the environmental characteristics of wireless can be solved. In addition, it is possible to perform a pay-as-you-go billing according to the use of the wireless Internet platform of the mobile communication network with NAPT management in the one-phone AP.
