5G QoS Identifier
It is an identifier for QoS characteristics that influences scheduling weights, admission thresholds. Queue management, link layer protocol configurations, etc.
Allocation and Retention Priority
It is the information about the priority level, it covers pre-emption vulnerability and capability.
Reflective QoS Attribute
It enables the UE to map Uplink user plane traffic to QoS flows without SMF-provided QoS rules. This is achieved by creating UE-derived QoS rules on the received DL traffic.
It indicates whether notifications are requested from the NG-RAN. It is signaled as a part of the QoS profile.
Flow bit rates
It is the bit rate that is guaranteed by the network to the QoS flow over the Average time window.
Aggregate bit rates
It is the aggregate of the bit rates provided by N-GBR traffic.
These are the default values that are set as per various classes.
The maximum packet loss rate
It indicates the maximum rate for lost packets of the QoS flows that can be tolerated in the uplink and downlink direction.
Advantages of 5G QoS in NR (New Radio)
- It delivers critical information services for mission-critical users or organizations.
- It provides different prioritization levels for various different applications as perusers.
- It provides help to users during disasters and emergency situations such as floods, earthquakes, etc.
- The service is always available for emergency callers.
