Claim:
1. An Offline Charging System (OFCS) comprising: a primary charging function including a processor configured to receive at least one accounting request for a session from a charging trigger function, and to generate a partial Charging Data Record (CDR) for the session based on the at least one accounting request; while the session is still active, the primary charging function is configured to store the partial CDR in memory, to send a copy of the partial CDR to a billing domain, and to delete any previous partial CDRs for the session from memory so that the partial CDR in memory represents the most recent partial CDR for the session; the primary charging function is configured to detect a failure that causes the charging trigger function to send accounting requests to a secondary charging function instead of the primary charging function; and the primary charging function is configured to identify a remediation system that is able to generate a next partial CDR for the session after charging was handed over to the secondary charging function, and to route the stored partial CDR to the remediation system.
