Analytical Approach of Cost-Reduced Location and Service Management Scheme for LTE Networks

In this paper, we propose a cost-reduced location and service management scheme in LTE (Long Term Evolution) networks, where a per-user service proxy is created in order to serve as a gateway between the mobile user and all client-server applications engaged by the mobile user. Our results indicate that the centralized scheme performs the best when the mobile user’s SMR (service to mobility ratio) is low and \(\nu \) (session to mobility ratio) is high, while the fully distributed scheme per-forms the best when both SMR and \(\nu \) are high. Through analytical results, we demonstrate that different users with vastly different mobility and service patterns should adopt different integrated location and service management methods to optimize system performance.
