System and method for verifying connection relation communication data registered by network node

摘要

The present invention relates to a system node and, more particularly, to a system and method for monitoring communication data in a connection relationship which is detected by an exchange network node in a remote communication network and used to calculate a toll. In order to strictly determine the start, end, and / or duration of a particular function required during a communication connection and / or connection, the appropriate measurement point (30, 40) of the call simulator (60) first is the network node It is possible to detect the start and end of the communication connection. Next, a systematic measurement error occurs when a predetermined event (start and end of connection) is measured between the points (28, 29) of the actual event and the measurement points (30, 40). Systematic measurement errors are taken into account for the correction of time related data obtained in the call simulator (60).
