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:
identifying a first set of quality of service (QoS) parameters associated with a first radio access technology (RAT) and a second set of QoS parameters associated with a second RAT; obtaining information relating to a utilized network communication application and at least one QoS parameter in the first set of QoS parameters associated with the utilized network communication application; and mapping the at least one QoS parameter in the first set of QoS parameters associated with the utilized network communication application to at least one QoS parameter in the second set of QoS parameters independently of the utilized network communication application.
