Positioning a Mobile Subscriber in a Cellular Network System based on Signal Strength

Abstract

In this paper the study has been carried out for finding the position of a mobile subscriber from a network independent brokers ’ point of view. As each mobile device monitors signal strength, this helps in assisting the network to take timely handoff decisions. These signal strength measurements are referred to as NMR (Network Measurement Report). A detailed study was conducted to analyze the use of such parameters to locate a user under the coverage area of a BTS used in a cellular network. Use of these parameters implies that such a system work in a network independent manner. This paper discusses the issues in the implementation of such a system and includes the statistics collected using the simulation tool OPNET [1].
