11 . The network node as claimed in claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the network node to further perform at least: sending a data request to one of said selected user devices requesting said network measurement data when the user equipment has access to the at least one restricted access resource and/or is able to determine network measurement data for the at least one restricted access resource.
12 . The network node as claimed in claim 1 , further caused to perform one or more of:
receiving the one or more network node configuration messages from the control module with the resource indicators,
selecting the one or more user devices based on their belonging to the one or more groups,
