The present application relates to a method for detecting and determining a failure probability (pA) of a radio network. The method is characterized in that devices of the radio network cyclically transmit operating parameters to a central computer wherein each transmitted operating parameter comprises an operating value of the respective device and a detection time point (t) of the operating value. All transmitted parameters and values can be viewed at any time by accessing the central computer. The central computer cyclically stores the operating values of all operating parameters detected within a predefined time interval (T) as the respective operating constellation and checks the radio network for a failure (A). The central computer cyclically creates a model based on the stored operating constellations and failures (A), which assigns a failure probability (pA) to each possible operating constellation.
