Most existing solutions related to FBS focus on detection aspects rather than locating its position. However, once an FBS is detected in a network, it’s crucial to determine its location precisely and remotely so preventive actions can be taken.
We propose a network-based localization method for estimating the exact geographical position of an FBS whose existence is already detected in a cellular network. Our method relies on a comparative pairwise analysis of the Reference Signals Received Power (RSRP) values, which are reported by the UEs in the vicinity of FBS as a standard procedure through their measurement reports. We have implemented and experimentally evaluated our proposed method in the Network Simulator 3 (ns-3) and showed that it accurately estimates FBS locations with meter-level precision under different scenarios in a cellular network.
