Abstract:
1. A method for verifying the connection-related communications data registered by a network node, where the connection-related communications data are used for the calculation of charges, the method comprising: establishing at least one predetermined test communication connection; clearing the predetermined test communication connection via the network node; registering a time of an event required for calculating the charges at a predetermined measuring point and in the network node; registering a time of at least one additional event required for calculating the charges at at least one of the predetermined measuring point and at least one additional predetermined measuring point and in the network node, the predetermined measuring points lying outside of the network node; determining a systematic temporal measuring error between a location of an occurrence of an actual event and the registration of the time of the event at the respective predetermined measuring point; generating a reference data record that contains time-related data generated from the events registered at at least one of the measuring points; generating at least one connection-related communications data record in the network node that contains time related data that describe the events registered in the network node; correcting the time-related data of the reference data record by the systematic temporal measuring error; comparing the reference data record to the at least one connection-related communications data record; and determining if a difference between the time-related data of the connection-related communications data record and of the reference data record lies within a predetermined range.
