Abstract: An apparatus for anomaly detection in a network, using an autoencoder including an encoder and a decoder. The apparatus includes a processor and a memory including computer program code, causing the apparatus to: providing the decoder with network configuration parameters used to obtain calculated network performance indicators, obtaining reconstructed network performance indicators from the decoder based on the network configuration parameters used to obtain the calculated network performance indicators, comparing the reconstructed network performance indicators with the calculated network performance indicators, detecting an anomaly when observing a deviation between the reconstructed network performance indicators and the calculated network performance indicators, providing the encoder with the calculated network performance indicators, obtaining estimated network configuration parameters from the encoder based on the calculated network performance indicators, detecting that the anomaly is related to the network configuration parameters.

Abstract: Disclosed is a solution for managing a radio map based on radio fingerprinting measurements. A method comprises: acquiring a radio map of an area, the radio map based on radio frequency measurements performed between at least one access node of a wireless network and terminal devices within the area; detecting at least one gap in the radio map and determining geographical coordinates of the at least one gap; causing transmission of a message comprising at least one information element requesting for additional measurements and comprising the geographical coordinates of the at least one gap; in response to the message, receiving at least one radio frequency measurement report related to at least one terminal device and comprising radio frequency measurement data and at least one measurement location where the radio frequency measurement data has been measured; and updating the radio map on the basis of the radio frequency measurement data.
