Abstract

The 3GPP Security Group has identified the detection of Rogue Base Stations (RBS) in 5G networks as one of the leading security challenges for users and network infrastructure. Motivated by this, RBS-MLP, a novel deep learning model, has been developed to identify RBSs. The model uses signal strength measurements in each mobile device’s periodic measurement reports as input data, a reliable metric readily available to the system. We investigate the impacts of various sizes of datasets, different window sizes of received signal strength, and different proportional splits of the dataset into training and test data to evaluate the performance of the proposed model. We further demonstrate RBS-MLP using a realistic dataset of received signal strength measurements for a vehicle driving along various sections of a road, providing a use case to demonstrate the use of RBS-MLP to improve the safety of mobile networks. Experimental results reveal that RBS-MLP is well suited as a 99.999% accuracy classification model and provides a new baseline method for RBS detection.
