Abstract

In known telephone systems it is very difficult to change call detailed records CDR formatted from a raw data flow. In the proposed method, the exchange supplier formats a special mother form, which is a file and which shows in plain language (in ASCII form) all names and parameters of fields in the raw data flow. The operator has a program using a graphic interface and showing the mother form in the display. Beside it a user form blank is seen and the user selects the fields he desires simply by dragging with the mouse the field of his choice from the mother form into the user form and by dropping the field here (drag and drop). In this manner the user formats his own form, which contains such data only which he wishes to have in the CDR. When the user form has arrived at the telephone exchange and at the billing center, it can be activated at any time. The formatting process hereby extracts from the raw data flow the data corresponding to fields stated in the form, thus formatting the CDR and sends it to the billing center, which using the same form made by the user will interpret the data contained in the received CDR, that is, it creates fields and attaches data belonging to fields from the CDR. Thus, the names of fields are not transferred from the exchange to the billing center.
