Title: Serialized prevention of duplicate charging data records

Abstract: The invention allows serialized prevention of duplicate charging records so that loss of charging data records does not occur even in cases of multiple charging gateways being down or otherwise unreachable at a time. In response to detecting no acknowledgement received from a first charging data record collection unit for a charging data record set, it is checked whether processing of any charging data record set marked as a potential duplicate is currently pending. In response to discovering pending processing of at least one charging data record set marked as a potential duplicate, completion of the pending processing is detected. In response to the detected completion, a second charging data record collection unit is selected as a temporary backup. The charging data record set is then transferred to the second charging data record collection unit for processing as a potential duplicate.
