Accurate localization and tracking of mobile terminals

In mobile networks many new services are being planned based on the knowledge of mobile terminals location. Mobile terminal geolocation is aimed at using the cellular network infrastructure and protocols in order to provide a reliable and accurate estimate of mobile terminals positions without the need for global positioning systems such as GPS. In this paper a lookup table correlation techniques with multiple position estimation and optimal location is presented. Our approach to improve precision in location and tracking is based on advanced propagation models used for mobile radio networks design and GIS (Geographical Information Systems) querying in conjunction with Kalman predictive filtering.
