The 5QI values have one-to-one mapping to standardized combination of 5G QoS attributes, as shown in Table 1.4. The 5G QoS characteristics for preconfigured 5QI values are preset in the AN, whereas the dynamically assigned 5QI values are signaled as part of the QoS profile. 182 Chapter 1 The ARP contains information about the priority level, the preemption capability and the preemption susceptibility. The priority level defines the relative importance of a resource request. This allows deciding whether a new QoS flow may be accepted or should be rejected in case of resource limitation, which is typically used for admission control of GBR traffic. It may also be used to decide which of the existing QoS flows to preempt in limited resource scenarios. The range of the ARP priority level is from 1 to 15, with 1 as the highest priority le
