Abstract
A charging detail record transmission capability is provided herein. A mobile gateway (MG) generates charging detail records (CDRs) intended for delivery to a charging gateway function (CGF). The CDRs are propagated toward both a first and second charging data function (CDFs). The first and second CDFs buffer the CDRs. The first CDF is configured for propagating CDRs toward the CGF. The second CDF is configured for propagating CDRs toward the CGF when the first CDF fails. The CGF is configured for acknowledging receipt of CDRs to the first or second CDF from which the CDRs are received. The first CDF is configured for acknowledging, to the second CDF, receipt of acknowledgment messages from the first CDF. The second CDF is configured for, upon failure of the first CDF, initiating a process for determining which of the CDRs buffered at the second CDF need to be propagated to the CGF in order to ensure that none of the CDRs generated by the MG are lost due to the failure of the first CDF.
