  • Method and device for checking accuracy of call data records in telecommunications systems
    Patent number: 6385444
    Abstract: A method and device for checking a telecommunication system (4) with respect to an accurate routine detection of system-internal call data records (13, 14). Various communications connections are established and later terminated between two subscriber stations (2,3) via the telecommunication system (4) on the basis of predefined communication parameters; further call data records (10a,10b) are independently prepared and saved from these communications connections at both of these subscriber stations (2,3); and the system-internal call data records (101013) for said communications connections that are routinely created by the telecommunications system (4) itself, are compared to the further call data records (10a, 10b).
