摘要

A method for determining a confidence limit for a telecommunication network element, whereby the number of data transmission connections established through the network element is stored into a database and a relative value as a ratio of the number of faulty operations in the network element to the number of data transmission connections is determined. A variable describing the relative number of faulty operations is assigned a target value for which a confidence limit is set, the deviation of the confidence limit from the target value changing in proportion to the number of the data transmission connections. The deviation of the confidence limit in relation to the target value becomes either smaller, in response to an increase in the number of data transmission connections, or larger, in response to a decrease in the number of data transmission connections. The confidence limits of the telecommunication network element can be updated automatically.
