Abstract

Abstract:
Location management plays an important role in 3G-PCS cellular networks. The
challenge of supporting rapidly growing numbers of mobile subscribers, while
constrained by limited radio spectrum, is being faced by cellular network operators
worldwide. In this work a dynamic distance-based location update with sequential
paging with no delay constraint algorithm has been considered and compared with other
location algorithms in terms of saving radio resources. The location management
strategy was implemented in 3G PCS architecture based in cellular systems. The
mobility model outputs the cellular parameters and location update messages count
during the movement of the mobile station. The dynamic distance-based location update
and paging algorithm outperforms the static and other dynamic location update
algorithms in terms of the number of location update and paging messages and
preserves the channel resources.
