Claim 13:
14. A wireless device in a communications network, for providing second information to a network node to allow the network node to determine which of a first category associated with a first wireless device behaviour and a second category associated with a second wireless device behaviour, wherein the wireless device comprises a processing circuitry configured to:
receiving a request for the second information from the network node, wherein the second information comprises one or more of measurements on dedicated uplink pilot transmissions, sounding references signal (SRS), Random Access Channel (RACH) transmissions and their respective measurements in neighboring base stations, periodic downlink measurement reports comprising measurements of reference signal received power from different cells, channel state information reference signal (CSI-RS), and related measurement reports, and wherein the wireless device has already met a primary criterion based on classification of first information, wherein the first information comprises one or more measurements of timing advance (TA) measurements, an amount of requested uplink resources, uplink signal strength measurements, handover statistics, line of sight detection in downlink; and
transmitting the second information to the network node, wherein a secondary criterion is associated with the second information, and wherein the wireless device is classified into the first category only if the wireless device meets both the primary criterion and the secondary criterion, wherein the step of determining which of the wireless devices that meet all of the at least one primary criterion also meet all of at least one secondary criterion is also based on the first information, wherein the at least one primary criterion are such that wireless devices meeting all of the at least one primary criterion have a first false positive rate and a first true positive rate of being in the first category, wherein the secondary criterion is such that wireless devices meeting the secondary criterion have a second false positive rate and a second true positive rate for being in the first category, wherein the second false positive rate is lower than the first false positive rate and the second true positive rate is lower than or equal to the first true positive rate, and wherein the first category comprises a drone category and the second category comprises a non-drone category.
