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. The service proxy is always co-located with the mobile user's location database such that whenever the MU's lo-cation database moves during a location handoff, a service hand-off also ensues to co-locate the service proxy with the location database. This allows the proxy to know the location of the mobile user at all times in order to reduce the network communication cost for service delivery. We analyze four integrated location and service management schemes. Our results indicate that the centralized scheme performs the best when the mobile user's SMR (service to mobility ratio) is low and (session to mobility ratio) is high, while the fully distributed scheme per-forms the best when both SMR and are high. In all other conditions, the dy-namic anchor scheme is the best except when the service context transfer cost is high under which the static anchor scheme performs the best. Through analytical results, we demonstrate that different users with vastly different mobility and ser-vice patterns should adopt different integrated location and service management methods to optimize system performance.
