1 Scope p. 7
The present document studies potential enhancements for the management of Trace/MDT based on the existing 5G data collection job "TraceJob" specified in TS 28.621, TS 28.622 (stage 2), TS 28.623 (stage 3) and the Trace/MDT management framework specified in TS 32.421 (stage 1), TS 32.422 (stage 2) and TS 32.423 (stage 3). The document provides conclusions and recommendations on the next steps in the standardization.
