METHOD AND SYSTEM FOR COLLECTING BILLING DATA IN END TO END SERVICE

摘要

A method and a system for collecting charge information in an end-to-end service are provided to enable packet charging in an end-to-end service environment and enable selective charging such as packet-based charging and time/duration-based charging, and improve the accuracy of charge data in consideration of UDR(Usage Data Record) and CDR. A method for gathering charge information in an end-to-end service comprises the following steps of: receiving first charge information in correspondence to the provision of the end-to-end service from a session management device(S610); receiving second charge information in correspondence to data amount transceived between arbitrary terminals for using the end-to-end service; repeating above first and second stages until the provision of the end-to-end service is closed and respectively generating first CDR(Call Detail Record) data and second CDR data by using respectively received plural charge information; and generating integrated CDR data by using the first and second CDR data based on correlation data(S660).
