The present document describes Trace data definition and management. It covers the trace records content, their format
and transfer across UMTS networks, EPS networks or 5GS networks. GSM Trace is outside of the scope of this
The present document also describes the data definition for Minimization of Drive Tests (MDT) across UMTS networks
or EPS networks.
The objectives of the present document are:
To provide the descriptions for a standard set of Trace and MDT data;
To define the common format of trace and MDT records; and
To define a method for the reporting of Trace and MDT results across the management interfaces.
Clause 4 details the various Trace records content, Annex A provides Trace and MDT report file format, Annex B
provides the trace report file conventions and transfer procedure, Annex C provides the trace reporting functional
architecture and Annex D provides some trace and MDT files examples. Trace and MDT concepts and requirements are
covered in TS 32.421
while Trace control and configuration management are described in TS 32.422
The definition of Trace and MDT data is intended to result in comparability of Trace and MDT data produced in a
multi-vendor wireless UMTS and/or EPS network.
The following is beyond the scope of the present document, and therefore the present document does not describe:
Any notification mechanisms or IRPs for trace. Only file transfer mechanism is specified for trace data transfer;
Any data compression mechanisms for trace data transfer;
Any Trace capability limitations (e.g. maximum number of simultaneous traced mobiles for a given NE).
