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.

Handling of NRS and BCM in PCRF and GW

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at a policy and charging rules node (PCRN) from a requesting entity, a message including a request associated with at least one service data flow (SDF); extracting a subscriber identifier and a first identifier from the message; retrieving a subscription record associated with the subscriber identifier, wherein the subscription record is associated with a first plurality of subrecords; identifying an first subrecord from the plurality of subrecords based on the first identifier; and conditionally fulfilling the request based on a first value stored in the first subrecord.

Method and system for authorizing sessions using subscriber database

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at the policy and charging rules node from a requesting entity, a message including a request associated with at least one service data flow (SDF), wherein the request includes at least one requested bandwidth; extracting at least one subscriber identifier from the message; retrieving a subscription record associated with the at least one subscriber identifier; determining whether the request should be fulfilled by performing at least one comparison of the at least one requested bandwidth for the SDF against at least one field of the subscription record; if the request should be fulfilled, establishing the SDF; and if the request should not be fulfilled: generating a response message that indicates that the request was rejected, and transmitting the response message to the requesting entity.
