Abstract

According to an aspect of the present invention, a method of operating a NE network node of a communication network is provided, the network node being connected via the communication network to at least one user device. The method comprises: receiving a request at the NE network node to carry out a MDT measurement for one of the at least one user device; determining, at the NE network node, whether carrying out the MDT measurement or processing or reporting a result of the MDT measurement requires a user consent, based on data of a MDT privacy matrix; determining, at the NE network node, whether a consent indicator which is assigned to the user device indicates allowance to carry out the MDT measurement, or indicates allowance of processing or reporting the result of the MDT measurement if the MDT privacy matrix indicates that a user consent is necessary; and carrying out the MDT measurement at the NE network node and/or processing the result of the MDT measurement and/or reporting the result of the MDT measurement to a further network node of the communication network if the consent indicator indicates that the MDT measurement can be carried out or the result of the MDT measurement can be processed or reported.
