There is provided mechanisms for classifying microwave link data of a microwave system comprises a point-to-point wireless microwave link. The method is performed by a controller entity. The method comprises obtaining microwave link data in terms of a set of performance affecting values for the point-to-point wireless microwave link. Each performance affecting value in the set pertains to a respective performance affecting property of the point-to-point wireless microwave link. The method comprises classifying the microwave link data to operating conditions in a set of operating conditions, where each operating condition is associated with its own subset of the performance affecting properties, by for each operating condition, estimating a probability value using the performance affecting values of the subset of the performance affecting properties associated with that operating condition.

Classification of microwave link data

The method comprises sampling transport data received on the transport link to determine properties of the transport link. The method comprises detecting the disturbance of the transport link based on the determined properties of the transport link. The method comprises, responsive to the detecting the disturbance, determining, based on the sampled received transport data, the cause of the disturbance. The method further comprises, responsive to detecting the disturbance, refraining from transmitting an indication of the disturbance or transmitting the indication of the disturbance with an instruction for resolving the disturbance.

Disturbance detection for transport links

There is provided mechanisms for classifying microwave link data of a microwave system comprises a point-to-point wireless microwave link. A method is performed by a controller entity. The method comprises obtaining, in time windows, microwave link data in terms of signal quality measurement values and received power values for the point-to-point wireless microwave link. The method comprises classifying per time window, the microwave link data per time window to operating conditions in a set of operating conditions by, from the signal quality measurement values and received power values per time window, estimating probability values for each of the operating conditions according to a mapping, as learned through training, between pieces of microwave link data and operating conditions.
