QoS Model

PreviousProceduresNextMobility in 5G

Last updated 2 years ago

The QoS profile of a QoS flow contains QoS parameters: For each QoS flow:

  • A 5G QoS Identifier (5QI).

  • An Allocation and Retention Priority (ARP).

In case of a GBR QoS flow only:

  • Guaranteed Flow Bit Rate (GFBR) for both uplink and downlink.

  • Maximum Flow Bit Rate (MFBR) for both uplink and downlink.

  • Maximum Packet Loss Rate for both uplink and downlink.

In case of Non-GBR QoS only.

  • Reflective QoS Attribute (RQA): the RQA, when included, indicates that some (not necessarily all) traffic carried on this QoS flow is subject to reflective quality of service (RQoS) at NAS.
