A.10 Monitoring of Unrestricted volume in NG-RAN

Measuring the share of unrestricted user data volume in the NG-RAN is important, to show the gNB ability to handle small data transfers efficiently and to see how large share of the volume that is part of the UE throughput measurement. It is not meaningful to measure throughput for data transfers so small that they fit in one single slot but it is still important to know how much such transfers can be handled by the gNB.

When network slicing is supported by the NG-RAN, multiple s S-NSSAIs may be supported. The share of unrestricted volume for each S-NSSAI is then of importance to the operator to pinpoint a specific performance problem.
