A noble cost optimized location management scheme for frequent visitors in mobile network

This paper proposes a cost optimized location management scheme based on replicated databases utilizing the advantage of short term events and update only the replicas of users frequently visited location area. This method updates HLR database after every 24 hours whereas in case of VLR database is updated after every 1 hour. It reduces database overloading problems and the total location management cost. Comparison of this scheme with that of GSM shows that the proposed scheme performs better and in general 14% to 25% improvement in total cost in Location Management has been achieved than previous schemes.
