Enhanced qos control in pcrf

A method in a Mobility Management Entity/Serving General packet radio service Support Node, (MME/SGSN) for handling User Equipment-Aggregated Maximum Bit Rate, (UE-AMBR) of a wireless device in a communications network, wherein the MME/SGSN comprises a direct interface with a Policy and Charging Rules Function PCRF node, wherein the MME/SGSN comprises a subscribed UE-AMBR received from a Home Subscriber Server/Home Location Register, HSS/HLR, which subscribed UE-AMBR is associated with a wireless device subscription;

• the method comprising:
• transmitting the subscribed UE-AMBR to the PCRF node using the direct interface;
• receiving a UE-AMBR from the PCRF node;
• and
• calculating a used UE-AMBR based on the UE-AMBR received from the PCRF node.

A Policy and Charging Rules Function, (PCRF) node, for handling User Equipment-Aggregated Maximum Bit Rate (UE-AMBR) associated with a wireless device in a communications network, wherein the PCRF node is adapted to comprise a direct interface with a Mobility Management Entity/Serving General packet radio service Support Node, MME/SGSN, the PCRF node comprises:

• a receiver adapted to receive a subscribed UE-AMBR from the MME/SGSN using the direct interface, which subscribed UE-AMBR is associated with a wireless device subscription;
• a calculating unit adapted to calculate, when triggered, a UE-AMBR based on the subscribed UE-AMBR and based policies associated with the wireless device;
• and
• a transmitter adapted to transmit the calculated UE-AMBR to the MME/SGSN using the direct interface.
