Abstract

A method of authenticating and charging a client using a web infoshop service system comprising the steps of: transmitting protocol address information from the service system to the client when the client accesses the service system and selects a protocol access; when a user request to the service system is for a charged content provider, adding an authentication value to the user request, transmitting the user request including the authentication value from the service system to the charged content provider, and transmitting information corresponding to the user request from the content provider to the client; and when the client cancels the protocol access and notifies cancellation information to the service system, transmitting charging information using the service system.

Claims

1. A method of authenticating and charging a client using a web infoshop service system comprising the steps of:

transmitting protocol address information from the service system to the client when the client accesses the service system and selects a protocol access;

when a user request to the service system is for a charged content provider, adding an authentication value to the user request, transmitting the user request including the authentication value from the service system to the charged content provider, and transmitting information corresponding to the user request from the content provider to the client; and

when the client cancels the protocol access and notifies cancellation information to the service system, transmitting charging information using the service system.

2. The method according to claim 1, wherein the step of transmitting the protocol address information comprises the steps of:

when the client performs dial-up access to a telephone network and internet matching equipment and requests point-to-point protocol connection and internet protocol address information, transmitting the internet protocol address information requested by the client from the telephone network and internet matching equipment to the client; and

transmitting point-to-point protocol information from the telephone network and internet matching equipment to the service system.

3. The method according to claim 2, wherein the step of transmitting the internet protocol address information comprises the steps of:

determining whether the user request is a first use request for the charged content provider;

if the request is the first one, transmitting items of official announcement and charging information of the content provider to the client;

when the client selects to use the content provider, storing user selection items in a database, adding the authentication value to the user request, transmitting the user request including the authentication value, and transmitting the information corresponding to the user request from the content provider to the client;

if the user request is determined not to be the first one at the step of determining whether the user request is the first one, examining the database to find out content of the user selection with respect to the charged content provider;

after the step of examining the database, when the client selects to use the content provider, adding the authentication value to the user request, transmitting the user request including the authentication value, and transmitting the information corresponding to the user request from the content provider to the client; and

after the step of examing the database, when the client does not select to use the content provider, performing proxy process.

4. The method according to claim 3, wherein the step of transmitting the charging information comprises the steps of:

if the client cancels the point-to-point protocol connection, transmitting the charging information of the charged content provider to a service management system internally located in the service system; and

if the client cancels modem access, transmitting dial-up access time charging information from the telephone network and internet matching equipment to the service management system.
