Abstract
Systems and methods that generate a partial Charging Data Record (CDR) when charging transfers from a primary charging function to a secondary charging function due to a failure. In one embodiment, the system receives an interim accounting request for a session from a secondary charging function after charging was transferred from the primary charging function. The system then opens a new partial CDR for the session based on the interim accounting request. The system receives a prior partial CDR for the session from the primary charging function, parses the prior partial CDR to identify a CDR timestamp, and records a start time in the new partial CDR based on the CDR timestamp. The system parses the interim accounting request to identify an accounting timestamp for the session, records an end time in the new partial CDR based on the accounting timestamp, and closes the new partial CDR.
