Abstract
Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN), the method including: receiving a credit control request (CCR) message from a packet data network gateway (PGW) based upon a general radio packet service (GPRS) internet protocol connectivity access network (IP-CAN) session request; determining that an operator policy rule specifies an aggregate maximum bit rate (APN-AMBR) value; determining that the CCR message includes an APN-AMBR value; setting an APN-AMBR value for the GPRS IP-CAN session to the APN-AMBR value specified by the operator policy rule; setting a GPRS IP-CAN session maximum bit rate download/upload (MBR DL/UL) value to the lowest of the APN-AMBR value specified by the operator policy rule and a subscriber MBR DL/UL value; and sending a credit control answer (CCA) message to the PGW with the selected APN-AMBR and MBR DL/UL values.
