4 Overview p. 7
The UE level measurements, i.e., the measurements per UE, in addition to the traditional performance measurements which are aggregated for the UEs to a measured object (e.g., a cell), are required to support AI/ML for NG-RAN, and NWDAF analytics.
The UE level measurement is produced by 5GC Network Function or NG-RAN node for a particular UE, and provided by the MnS producer to the authorized consumer(s).
5 UE level measurements collection and reporting p. 7
The UE level measurements are collected by the MnS consumer from MnS producer via the Provisioning MnS (see TS 28.532) through managing the MOI of TraceJob (see TS 28.622, and TS 28.623) with the specific job type(s).
In 5G system, the 5GC UE level measurements collection and reporting are supported by extending the Trace mechanisms for both signalling and management based activation; the NG-RAN UE level measurements collection and reporting is supported by MDT mechanisms for both signalling and management based activation. The Trace Session activation/deactivation, Trace Recording Session start/stop, and 5GC UE level measurements specific configuration parameters, and MDT specific configuration parameters, and 5GC UE level measurements and MDT measurements reporting are specified in TS 32.422. The Trace Record content, and Trace Report file and streaming format for 5GC UE level measurements and MDT measurements are specified in TS 32.423.
