A Method for Batch Processing of Accounting in AAA System

摘要

PURPOSE: An AAA(Authentication,Authorization,Accounting) protocol-based batch process billing method is provided to batch-process billing data which has been failed for transmission during a real time billing processing. CONSTITUTION: An AAA client requests user authentication from an AAA server(S301). Upon completion of user authentication, the AAA server generates related data on an authentication success or failure and transmits it to the AAA client(S302). The AAA client informs the user whether access to a user-requested resource is allowed or rejected. If allowed, the user can receive a service, and in this case, the AAA client generates billing data, generates a billing data transmission request(ACR) and transmits it to the AAA server(S303). The AAA server checks the ACR message and stores it(S304). If the AAA server successfully transmits corresponding billing data to the AAA client(S305), billing data transmission success is confirmed(S307). If billing data transmission is failed(S306), billing data transmission failure is confirmed(S308). In the case of the billing data transmission failure, the AAA client sets an ID for batch-billing application, generates a billing request message(ACR) and transmits it to the AAA server(S309). Then, the AAA server updates a corresponding session(S310). The AAA server generates a billing response message(ACA) and transmits it together with a process result to the AAA client(S311).
