摘要

In this paper, we propose a novel enhanced cell ID (E-CID) based positioning method for LTE network using reference signal received power (RSRP), azimuth parameters and COST 231 Walfish-Ikegami path loss model. The distance between serving eNodeB and user equipment (UE) is calculated using RSRP and COST 231 Walfish-Ikegami path loss model, and based on the distance calculation, the position of UE is calculated using the azimuth and beamwidth values of the serving eNodeB. The proposed positioning method is evaluated by using real measurement data which are collected in Istiklal Street, Istanbul, Turkey where the COST 231 Walfish-Ikegami path loss model is applicable. The performance of the proposed positioning method is obtained in terms of cumulative distribution function (CDF) and the results are compared with the CID based positioning method which is currently employed on serving mobile location center (SMLC). The results reveal that the proposed positioning method for LTE networks outperforms the CID based positioning method and can be used in the practical localization applications in LTE networks.
