Abstract
A method, apparatus, and machine readable storage medium is disclosed for handling Network-Request-Support (NRS) and Bearer Control Mode (BCM) at a Policy and Charging Rules Node (PCRN) and a Evolved Packet Core (EPC) gateway node. Embodiments maintain corresponding buffers for NRS values at the PCRN and the gateway and maintain synchronization between them. A gateway sends a credit control request (CCR) message to a PCRN and updates a local NRS buffer at the gateway when a successful credit control acknowledgement (CCA) response is received from the PCRN. Similarly, the PCRN updates a local NRS buffer at the PCRN when a successful credit control acknowledgement (CCA) response is sent to the gateway.
