The invention relates to a method and system for diagnosing communication connections in a communication system. The invention enables the provision of a plurality of first diagnosis units and at least one second diagnosis unit, wherein the first and second diagnosis units each are assigned to a communication connection of the communication system and are configured for determining a value of a diagnosis variable of the respectively assigned communication connections, and provides for determining a value of at least one diagnosis variable by each of the first diagnosis units, determining a value of at least one diagnosis variable by the at least one second diagnosis unit, transferring the values determined by the first diagnosis units to an evaluation unit, statistically evaluating the transferred values by the evaluation unit, and diagnosing the values determined by the at least one second diagnosis unit depending on the statistical evaluation by the evaluation unit.

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; andf) 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. 2. The method according to claim 1, wherein the steps b) to f) are repeated in predetermined time intervals and/or in case of a change of the configuration of the communication system. 3. The method according to claim 1, wherein the predetermined proportion lies below 100%. 4. The method according to claim 1, wherein statistically evaluating by the evaluation unit comprises determining an average value of at least one diagnosis variable. 5. The method according to claim 1, wherein the at least one diagnosis variable comprises at least one variable or a temporal change of a variable, wherein the variable is selected from a group comprising the variables: (i) transmitting power,(ii) receiving power,(iii) path length of the respective communication connection,(iv) bit error rate,(v) checksum error rate(vi) attenuation, and(vii) transmission bandwidth. 6. The method according to claim 1, wherein for at least one duplex communication connection having a first and a second data direction, a first value for the first data direction and a second value for the second data direction of the at least one diagnosis variable is determined, and wherein the diagnosis comprises comparing the first and second value to each other and/or to an upper and/or lower limit value and/or average value determined by the statistical evaluation. 7. The method according to claim 1, wherein the second diagnosis unit or a central device of the communication system or a superimposed communication system comprises the evaluation unit. 8. The method according to claim 1, wherein for detecting a predetermined error type for the at least one diagnosis variable, a limit value for a deviation from an average value of the respective diagnosis variable determined by the statistical evaluation is defined. 9. The method according to claim 1, wherein the communication connections are configured as wireless or optical connections. 10. An electronic component, configured for carrying out a method according to claim 1, comprising: a receiver unit for receiving values of at least one diagnosis variable of a plurality of communication connections of a communication system;a storage for storing the received values; andan evaluation unit for statistically evaluating all received values and for diagnosing, for error detection, the received values of at least one selected communication connection depending on the statistical evaluation, wherein statistically 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 diagnosing comprises comparing the received values of the at least one selected communication connection 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. 11. A communication system, configured for carrying out a method according to claim 1, comprising: a plurality of communication connections;a plurality of diagnosis units that are each assigned to at least one of the communication connections and are configured to determine a value of at least one diagnosis variable of the respectively assigned communication connections; andat least one evaluation unit, wherein the diagnosis units are configured to transfer determined values of the at least one diagnosis variable to the at least one evaluation unit, wherein the evaluation unit is configured to statistically evaluate all received values and for diagnosing, for error detection, the received values of at least one selected communication connection depending on the statistical evaluation, wherein statistically 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 diagnosing comprises comparing the received values of the at least one selected communication connection 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. 12. The method according to claim 1, wherein the predetermined proportion lies below 95%. 13. The method according to claim 1, wherein the predetermined proportion lies below 90%. 14. The method according to claim 1, wherein the predetermined proportion lies below 85%. 15. The method according to claim 1, wherein the predetermined proportion lies below 80%.
