DEVICE FOR ESTIMATING END-TO-END TRAFFIC OF TELEPHONE NETWORK USING ACCOUNTING DATA AND METHOD THEREFOR

摘要

PURPOSE: A device for estimating end-to-end traffic of a telephone network by using accounting data and a method therefor are provided to extract the number of complete end-to-end calls and call duration from accounting data information, and to extract occupancy of incomplete calls, thereby estimating the end-to-end traffic. CONSTITUTION: An extractor(50) for the number of completed end-to-end calls and call duration extracts the number of complete end-to-end calls and call duration by number with the use of accounting data information of an exchange. An extractor(60) for incomplete call statistics extracts ratios and average occupancy of incomplete calls for total attempted calls by using network traffic analysis. An end-to-end traffic calculator(70) calculates end-to-end traffic by exchange code with the use of the number of the complete calls, the call duration, and the ratios and the average occupancy of the incomplete calls.
