Method and system for authenticating pay-per-use service using EAP

A service access point comprising:

• a transmission unit transmitting signals to a client and to an authentication/authorization/accounting (AAA) backend server;
• and
• a reception unit receiving signals from the client and the AAA backend server;
• wherein the reception unit receives a service request from the client, the transmission unit transmits an EAP payment method (EAP_CC) request signal to request management information of the client, the reception unit receives an EAP_CC response signal comprising the management information of the client, the transmission unit retransmits the EAP_CC response signal that comprises the management information of the client to the AAA backend server that possesses the management information of the client after receiving the EAP_CC response signal, and the reception unit receives an EAP_CC approval signal approving the service request of the client from the AAA backend server.

A method of authenticating a pay-per-use service using an extensible authentication protocol (EAP), the method comprising:

• requesting a client to provide extensible authentication protocol (EAP) management information by transmitting an EAP payment method (EAP_CC) request signal;
• after receiving an EAP_CC response signal that includes the management information of the client, retransmitting the EAP_CC response signal to an authentication/authorization/accounting (AAA) backend server that possesses the management information of the client;
• and
• receiving an EAP_CC approval signal approving a service request of the client from the AAA backend server.

A method of authenticating a pay-per-use service using an extensible authentication protocol (EAP), the method comprising:

• requesting a client to provide an extensible authentication protocol (EAP) ID and a EAP password to be used in the service when a service request signal is received from the client;
• verifying the authenticity of the client by matching the EAP ID and EAP password in a central database that stores previous clients' EAP IDs, EAP passwords, and respective management information;
• transmitting an EAP_CC response signal to an authentication/authorization/accounting (AAA) backend server that possesses the management information of the client that is attained from the central database;
• and
• receiving an EAP_CC approval signal approving the service request of the client from the AAA backend server.
