Abstract
In this paper, we propose an efficient combined location management scheme using the concepts of the two existing location management schemes: the FLA scheme [1] and the Caching scheme [2]. The motivation behind the proposed scheme is to exploit the advantages of the two existing schemes. That is, the FLA scheme exploits locality in a user’s mobility pattern, and the Caching scheme exploits locality in a user’s calling pattern. By combining the advantages of both the FLA scheme and Caching scheme, the proposed scheme can reduce the frequent access to the HLR, and thus effectively results in significant reduction of the total location management cost. The analytical results indicate that the proposed scheme significantly outperforms the other existing schemes regardless of the mobile user’s call-to-mobility ratio in terms of the total location management cost.
