Minimization of Drive Tests ( MDT ) in Mobile Communication Networks

Drive tests are used for collecting data of mobile networks. This data is needed for the configuration and the maintenance of mobile networks. In order to execute drive tests, human effort is required. These measurements cover only a small piece of time and location of the network. The new idea is to use each device which is active in the network; this concept is referred to as Minimization of Drive Test (MDT). This means that standard mobiles should be used for measurements to provide data for the operators. The main difference between these tests is that MDT uses cheap mobiles whereas drive tests make use of high developed measurement equipment. This paper demonstrates that MDT can reduce drive tests, but that there are still use cases where MDT cannot replace drive tests.
