Abstract

PURPOSE: A method for billing a pay wireless Internet service is provided to receive a connection authentication number of a corresponding server from a base station through a short message, before using pay contents in a mobile communication terminal equipped with a WAP(Wireless Application Protocol) browser, so as to reduce authentication errors caused when furnishing a wireless Internet service. CONSTITUTION: If a terminal transmits a connection request signal for predetermined pay contents to a WAP gateway, the WAP gateway requests a short message to an SMS(Short Message Service) center(SP1,SP2). The SMS center requests an authentication key generating server to generate an authentication key(SP3). The authentication key generating server generates the authentication key and transmits the authentication key to the SMS center, and the SMS center transmits a short message including the authentication key to the terminal and a pay contents server(SP4,SP5). The terminal transmits a connection request signal including the authentication key to the pay contents server through the WAP gateway(SP6,SP7). And the pay contents server compares a pre-stored internal authentication key with the authentication key of the WAP gateway, if the keys are coincident with each other, to provide a service(SP8).

Description

Wireless Internet Pay Service Billing Method {WIRELESS INTERNET FEE SERVICE BILLING METHOD}

The present invention relates to a wireless Internet pay service billing method, and more particularly, to a wireless Internet pay service billing method to reduce the authentication error generated during wireless Internet billing.

In general, a bearer provided to a WDP layer in order for a wireless Internet web browser to perform communication includes UDP, SMS, and USSD methods.

The mobile terminal equipped with the web browser (WAP Browser) forms a network environment for accessing the Internet by attempting a data call. The web browser makes a communication request to the gateway when the network is opened. The gateway can communicate by sending a response signal.

When the web browser makes a communication request, the user agent of the HTTP header includes the terminal information (the wireless Internet provider's identification number, the terminal manufacturer, the terminal's software, the terminal's hardware information, the terminal's location information, and the terminal number). If a request is made by encoding a field (RFC2616), the server of the gateway or the CP side sets a criterion for charging or paying for a paid service based on the user agent field of the HTTP header.

While the web browser is performing web navigation (WAP Navigation), the billing for paid content (picture, melody, game download) provided by the content provider is the user agent of the HTTP header that sends the gateway when the terminal makes a communication request. The CP server determines the wireless internet provider's identification number and terminal number among the terminal's terminal information. That is, unlike the charging method for the data call, the user agent field of the HTTP header is charged.

In this case, when the web browser of the terminal transmits a communication request to the gateway, if the user agent field value of the untrusted HTTP header is sent or another user changes this value, an error may be inevitable when charging the paid service.

That is, even though the charging of the data is normal, the paid service charging is abnormally processed.

The present invention has been made in order to solve the above problems, by using a mobile communication terminal equipped with a web browser to receive a connection authentication number of the corresponding server from the base station as a short message before using the paid content, wireless Internet An object of the present invention is to provide a wireless Internet pay service billing method for reducing authentication errors that occur when providing a service.

1 is a flowchart illustrating a method for charging a wireless Internet pay service according to the present invention.

According to an aspect of the present invention, there is provided a terminal comprising: a first process of requesting, by a terminal, a short message to a SMS center when a terminal transmits a connection request signal for predetermined paid content to a web gateway; A second step of requesting, by an SMS, a short message request from the web gateway, to generate an authentication key to an authentication key generation server; Generating, by the authentication key generation server and transmitting the authentication key to an SMS center, the SMS center transmits a short message including the authentication key to a terminal and a paid content server; A fourth step of transmitting, at the terminal, a connection request signal including an authentication key to a pay content server through a web gateway; The paid content server compares the authentication key of the pay content with the authentication key of the web gateway and performs a fifth process of charging by providing a service.

Hereinafter, with reference to the accompanying drawings, the operation and effects of the wireless Internet pay service billing method according to the present invention will be described in detail.

1 is a flowchart showing the operation of the wireless Internet service paid billing method of the present invention. As shown in FIG. A first process (SP1, SP2) for requesting a short message; A second step (SP3) of requesting the authentication key generation to the authentication key generation server by the short message request from the web gateway in the SMS center; Generating, by the authentication key generation server and transmitting the authentication key to an SMS center, the SMS center includes a third process (SP4, SP5) for transmitting a short message including the authentication key to a terminal and a paid content server; A fourth step (SP6, SP7) of transmitting, at the terminal, a connection request signal including an authentication key to a pay content server through a web gateway; The paid content server includes a fifth process (SP8) of comparing the authentication key of the pay content server with the authentication key of the web gateway and providing a service when the coincidence is matched. The operation of the present invention will be described.

First, when a user transmits a connection request signal for predetermined paid content to a web gateway while the web browser of the terminal is activated (SP1), the web gateway requests a short message to the SMS center (SP2).

Then, the SMS center requests the authentication key generation server to generate the authentication key by the short message request of the web gateway (SP3).

Next, the authentication key generation server generates an authentication key and transmits it to the SMS center (SP4), that is, every time an authentication key generation request is generated, a random number is generated differently every time, and an ID is attached to the random number for authentication. Create a key.

Then, the SMS center transmits the authentication key received from the authentication key generation server to the pay content server, and also includes the authentication key in a short message to the terminal (SP5).

Then, the terminal extracts the authentication key included in the short message and includes it in the access request signal of the predetermined paid content, that is, adds the authentication key to the User Agent field of the HTTP header, and then transmits the access request signal to the web. Transfer to the paid content server through the gateway (SP6, SP7).

Next, the paid content server compares the authentication key previously transmitted by the SMS sensor with the authentication key input through the web gateway and provides a service if it matches (SP8).

That is, the paid content server receives the access request signal input through the web gateway, even if there is no authentication key in the User Agent Field of the HTTP header of the access request signal, or even if there is an authentication key in the User Agent Field of the HTTP header. If the authentication key does not match with the authentication key it owns, the service is rejected, and if the authentication keys match each other, the service is provided.

The specific embodiments or examples made in the detailed description of the present invention are only for clarity of the technical contents of the present invention, and should not be construed as limited to these specific examples and should not be construed in consultation. Various changes can be made within the scope.

As described in detail above, in the present invention, the user agent field of the HTTP header containing the terminal information does not have accurate terminal information, or a malicious user unfairly charges due to distortion of terminal information by a malicious user. This prevents the billing, and also has the effect of blocking the service error caused by the error of the terminal information.
