Abstract
Disclosed are techniques for detecting a potential false base station (FBS). In an aspect, a user equipment (UE) or a location server obtains a first location estimate of the UE based on a cellular network-based positioning procedure involving one or more cells, obtains a second location estimate of the UE based on a non-cellular network-based positioning procedure, determines whether or not a difference between the first location estimate and the second location estimate is greater than a distance threshold, and performs a mitigation operation based on the difference being greater than the distance threshold.
