Abstract
A method for default bearer translation with GBR bearer translation. A GBR bearer is known in UE, 5G-RAN, and SMFs from the existing QoS flow parameters from one or more QoS flows for a PDU session that includes an assigned value for guaranteed bit rate. In case a PDU session has multiple associated QoS flows that each include an assigned value for GBR, then each flow is determined as a candidate GBR bearer for the target E-UTRAN access. Each GBR bearer candidate is arranged in a priority order based on, for example, the QoS flow parameters (e.g., ARP), and the resulting EPS QCI when translating QoS flow parameters in 5G to a 4G representation. Hence common priority rules for 1:1 mapping between 5G representation and 4G representation can be used by the nodes having knowledge of the PDU session and the QoS flows characterized as GBR QoS flows.
