METHOD AND APPARATUS FOR QOS CONTEXT TRANSFER DURING INTER RADIO ACCESS TECHNOLOGY HANDOVER IN A WIRELESS COMMUNICATION SYSTEM

摘要

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.

1. A method, comprising:
initializing quality of service (QoS) for a packet flow over a first network; establishing a QoS context for the packet flow on a second network via tunneling to the second network in response to the initializing; monitoring for changes to the QoS for the packet flow over the first network; and updating the QoS context for the packet flow on the second network via the tunneling to the second network in response to respective monitored changes to the QoS for the packet flow over the first network.
