Introduced in 3GPP Rel-10, Minimization of Drive Test (MDT) is a standardized mechanism designed to enable operators to use user devices in a network to collect mobile network data, and thus, reduce the need for traditional drive tests, which are associated with high costs and time commitments and only provide a partial view of a network as testing is limited to locations with vehicle access.
The MDT solution, on the other hand, taps user equipment (UE) to collect field measurements, including radio measurements and location information.
