OVERCHARGING PREVENTION BY UNSENT DOWNLINK DATA VOLUME RECORD

摘要

The present invention provides a method for recording the unsuccessfully transmitted downlink data volume into the CDR generated by gateway support node in a telecommunication system. The method includes creating information relating to the unsuccessfully transmitted downlink data in a node and sending the information from the node to the gateway support node, to make the gateway support node know the volume of unsent downlink data. A node and gateway support node which adapted to prevent overcharging the user which is caused by the G-CDR are also provided.
