Abstract:
1. A method for diagnosis of communication connections in a communication system, comprising: a) providing a plurality of first diagnosis units and at least one second diagnosis unit, wherein the first and second diagnosis units are each assigned to at least one communication connection of the communication system and are configured to determine a value of at least one diagnosis variable of the respectively assigned communication connections; b) determining a value of the at least one diagnosis variable by each of the first diagnosis units; c) determining a value of the at least one diagnosis variable by the at least one second diagnosis unit; d) transferring the values determined by each of the first diagnosis units to an evaluation unit; e) statistically evaluating the transferred values by the evaluation unit, wherein the evaluating by the evaluation unit comprises determining at least one of an upper limit value and a lower limit value for the at least one diagnosis variable; and f) diagnosing, for error detection, the values determined by the at least one second diagnosis unit depending on the statistical evaluation by the evaluation unit, wherein the diagnosing comprises comparing the value determined by the at least one second diagnosis unit with the at least one of the upper limit value and the lower limit value, wherein as upper limit value for the at least one diagnosis variable, a value is determined below which value a predetermined proportion of the values of the respective diagnosis variable determined by the first diagnosis units lies, or wherein as lower limit value for the at least one diagnosis variable, a value is determined above which value a predetermined proportion of the values of the respective diagnosis variable determined by the first diagnosis units lies.
