Abstract
Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.
