PURPOSE: An apparatus and a method for managing user information of AAA servers in a mobile communication system are provided to improve the efficiency of data management and reduce response time by efficiently using user information. CONSTITUTION: A plurality of PSDN(Packet Data Service Node)s(100) receive a call setup request message for outputting an access request message corresponding to the call setup request message, and connect a call of a user after authentication. Dualized AAA(Authentication, Authorization, Accounting) servers(200) execute and output user authentication, and make out a query related to user information for transmitting the query. Dualized database management systems(300) analyze the query after receiving the query from a specific AAA server and simultaneously execute a locking work corresponding to the query. The dualized database management systems(300) output the result of the query to the specific AAA server. A share database(400) receives the user information from the database management systems(300) for storing the user information. |
