The present invention provides a method which uses a data audit function in order to maintain a consistency about a plurality of data stored as a replication data among data base nodes consisting of a mobile communication system. The method for auditing data based on timestamp criteria in replicated data bases in a digital mobile telecommunication system includes the steps of: (a) when there is a database access request, setting a time stamp about tuple accessed by the request, and managing a start, suspend, stop and resume events for a audit process; (b) managing a current status of the audit process, and information necessary for scanning each tuple; and (c) managing a request queue for the data base and CPU load. Accordingly, the present invention satisfies a system basic requirement being a real-time access in a mobile communication system including at least two data bases, maintains a consistency between two data replicated to each other, accurately controls a relationship between a mobile subscriber and a mobile terminal, and removes the incorrect data and the garbage data which may occur in a system operation, thereby effectively using the data base resource.
