US 2023/0069008 A1 · Quality of Service Framework Enhancements for 5G Service

Abstract

This disclosure relates to techniques for supporting multiple Quality of Service flows for a service data flow in a wireless communication system. The service data flow may include multiple categories of data with different Quality of Service parameters. Separate Quality of Service flows may be established for each of the categories of data with different Quality of Service parameters. A cellular network and a wireless device communicating data for the service data flow may apply packet detection rules or packet filters to determine on which Quality of Service Flow to communicate data packets of the service data flow, and may communicate the data packets accordingly.

Claims20

Dependent claims

An apparatus, comprising:

a processor configured to cause a wireless device to:
establish a service data flow (SDF) with an application function (AF) via a cellular network;
determine that the SDF includes at least two categories of data, wherein a first category of data for the SDF has different Quality of Service (QoS) parameters than a second category of data for the SDF;
communicate the first category of data for the SDF using a first QoS Flow;
and
communicate the second category of data for the SDF using a second QoS Flow,
wherein the first category of data for the SDF and the second category of data for the SDF are communicated using different QoS Flows based at least in part on determining that the first category of data for the SDF has different QoS parameters than the second category of data for the SDF.

4 more elements

A cellular network element, comprising:

a processor;
and
a network interface operably coupled to the processor,
wherein the cellular network element is configured to:
determine that a service data flow (SDF) between an application function (AF) and a wireless device includes at least two categories of packets, wherein a first category of packets of the SDF has different Quality of Service (QoS) parameters than a second category of packets of the SDF;
establish a first QoS Flow for the first category of packets of the SDF;
and
establish a second QoS Flow for the second category of packets of the SDF.

5 more elements

A cellular base station, comprising:

an antenna;
a radio operably coupled to the antenna;
and
a processor operably coupled to the radio;
wherein the cellular base station is configured to:
establish a wireless link with a wireless device;
transmit first packets to the wireless device on the wireless link using a first QoS Flow;
and
transmit second packets to the wireless device on the wireless link using a second QoS Flow,
wherein both the first packets and the second packets are associated with a service data flow (SDF).
