Method for performing AAA (Authentication, Authorization and Accounting) authentication during failure of database

Abstract

The invention discloses a method for performing AAA (Authentication, Authorization and Accounting) authentication during failure of a database. Since an AAA server has written information on public NAI (Network Access Identifier) and VPN (Virtual Private Network) into an xml (Extensible Markup Language) file, also reads IMSI (International Mobile Subscriber Identity) information and user binding information of a user from the database periodically and stores in a memory object cache component so as to perform false authentication during failure of the database when the database works normally, the AAA server reads the NAI and the VPN information from the xml file and acquires the IMSI information and the user binding information from the memory object cache component by taking IMSI+ 'auth' as keyword for mobile directory number (MDN) authentication, binding check, roaming authority control and group authorization when the database fails and the connection of the AAA server and the database fails. The method can guarantee that the user can still normally access the data traffic during failure of the database, so that the service quality of the user experience is improved; the serious consequence that the economic benefit and the social benefit of a telecom operator are affected at the time in the prior art is avoided, so that both the user and the operator win.

Description

technical field [0001] The present invention relates to a method for performing AAA authentication when a database fails, and to be more precise, relates to a method for AAA server to perform authentication and authorization by means of file authentication when both the primary and backup databases of AAA fail. Or users configured in the memory object cache component perform authentication and accounting operations to ensure business continuity. It belongs to the technical field of communication. Background technique [0002] Authentication, Authorization and Accounting The AAA (Authentication, Authorization, Accounting) server is located in the packet core network and is responsible for the functions of user authentication, authorization and accounting; that is, to identify the identity and authority of users when using network services and accessing resources AAA authentication plays a very important role in the business of telecom operators. [0003] see figure 1 , to ...

AI Technical Summary

Problems solved by technology

If the connection fails due to a database failure, the AAA server cannot obtain information about the mobile user number MDN and user type according to the IMSI; when performing AAA authentication, WAP (Wireless Application Protocol) services cannot be obtained because there is no MDN use

In addition, the binding information also cannot be read from the database, causing the binding logic in AAA authentication to fail to take effect

Therefore, during the entire process from the occurrence and discovery of database failures to finding and solving problems, all user access requests will be rejected because they cannot connect to the database, making users unable to access data services. This consequence will seriously affect and reduce user Experience, while bringing unpredictable losses to telecom operators
