US 2019/0357086 A1 · QUALITY OF SERVICE FLOW TO DATA RADIO BEARER MAPPING OVERRIDE BIT

Abstract

Disclosed are apparatuses for quality of service (QoS) flow to data radio bearer (DRB) mapping override bits. An apparatus of a user equipment (UE), includes one or more data storage devices, and one or more processors operably coupled to the one or more data storage devices. The one or more data storage devices are configured to store data corresponding to mapping of QoS flows to data radio bearers. The one or more processors are configured to map one or more QoS flows to a DRB in an uplink (UL) responsive to receipt, by the UE from a cellular base station, of a user plane packet in a downlink (DL) through the DRB if an override bit of the user plane packet indicates that reflective mapping should apply.

Dependent claims

An apparatus of a user equipment (UE), comprising:

one or more data storage devices configured to store data corresponding to mapping of QoS flows to data radio bearers;
and
one or more processors operably coupled to the one or more data storage devices, the one or more processors configured to:
map one or more quality of service (QoS) flows to a data radio bearer (DRB) in an uplink (UL) responsive to receipt, by the UE from a cellular base station, of a user plane packet in a downlink (DL) through the DRB if an override bit of the user plane packet indicates that reflective mapping should apply;
and
not map the one or more QoS flows to the DRB in the UL if the override bit of the user plane packet indicates that the UE should ignore the reflective mapping.

3 more elements

An apparatus of a user equipment (UE), comprising:

a cellular radio configured to receive, from a radio access network (RAN) node of a cellular data network, a user plane packet through a first data radio bearer (DRB), the user plane packet corresponding to a QoS flow, the user plane packet including an override bit configured to indicate whether reflective mapping of the QoS flow to the first DRB should take precedence over explicit mapping for the QoS flow;
and
one or more processors operably coupled to the cellular radio, the one or more processors configured to:
map the QoS flow to the first DRB in an uplink (UL) if the override bit indicates that the reflective mapping of the QoS flow to the first DRB should take precedence over the explicit mapping;
and
not map the QoS flow to the first DRB in the UL if the override bit indicates that the reflective mapping of the QoS flow to the first DRB should not take precedence over the explicit mapping.
