Abstract: The present disclosure provides a method and device for configuration of minimization of drive tests, in which a first node sends MDT status information to a second node; and the second node decides whether it is possible to configure a management-based logged MDT measurement for a UE. It is avoided that the MDT configuration information that is currently still valid is erroneously overwritten when the network reconfigures the MDT for the UE.
