Abstract
The present disclosure is directed at systems, methods and media for providing QoS differentiation between IP data flows by sorting data packets into bearers. If a first node in a communication network (e.g., a User Equipment or UE) determines that downlink packets received from a second node (e.g., a Packet Data Network Gateway or PDN-GW) via a specific bearer should be given reflective bearer treatment, the first node can be configured to send uplink packets back to the second node via the same bearer. By sending uplink traffic using the same bearer as downlink traffic, the first node can aid in ensuring that the correct QoS for the uplink traffic is used. Downlink packets or bearers can be configured to request reflective bearer treatment through reserved QoS Class Identifier (QCI) values, Allocation and Retention Priority (ARP) values, or through an indicator specifically defined for requesting such treatment.
