Configuration of Tracking Area Code (TAC) for Paging Optimization in Mobile Communication Systems

摘要

Recently, the mobile telecommunication traffics have been rapidly increasing due to the growth of smart phone services. In this paper, we propose a new scheme for configuration of TAC (Tracking Area Code) to maximize the paging success rates in the LTE-based mobile communication networks. The proposed scheme includes the initial configuration of TAC, the local optimization algorithm, and the re-clustering algorithm for further improvement of the TAC configuration. From the performance analysis with real traffic data of service provider, we see that the proposed TAC configuration scheme can improve the paging success rates in the LTE networks, compared to the existing TAC configuration scheme.
