It is proposed an apparatus for anomaly detection in a network using an automatic encoder comprising an encoder and a decoder. The apparatus comprises a processor and a memory comprising computer program code, such that the apparatus performs: providing a network configuration parameter to a decoder, the network configuration parameter being used to obtain a calculated network performance metric, and determining a network performance metric based on the network configuration parameter used to obtain the calculated network performance metric. Obtaining a reconstructed network performance indicator from the decoder, comparing the reconstructed network performance indicator with the calculated network performance indicator, detecting an anomaly when a deviation between the reconstructed network performance indicator and the calculated network performance indicator is observed, providing the calculated network performance indicator to the encoder, and outputting the reconstructed network performance indicator to the decoder. -obtaining an estimated network configuration parameter from the encoder based on the calculated network performance indicator,-detecting that an anomaly correlates to the network configuration parameter when a deviation between the estimated network configuration parameter and the network configuration parameter used to obtain the calculated network performance indicator is observed.
Description
technical field [0001] Various example embodiments relate generally to methods and apparatus for anomaly detection in a network. [0002] Specifically, they are applied to a radio access network (RAN) of a mobile communication system, such as a 5G (fifth generation) system using 5G NR (New Radio) as a radio access technology (RAT) defined by 3GPP. Background technique [0003] A radio access network includes base stations configured with network configuration parameters to communicate over the air with one or more user equipment using radio access technologies. [0004] Before a new base station version is deployed in the radio access network, the version should go through a testing and validation phase. This testing and validation phase includes configuring the base station using test network configuration parameters, operating the network like a customer using commercial equipment, end-to-end applications, and real-world scenarios, measuring network performance indicators...
