Telecommunication management; Subscriber and equipment trace; Trace data definition and management
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 specification..
The present document also describes the data definition for Minimization of Drive Tests (MDT) and 5GC UE level measurements across 3GPP 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, MDT records and 5GC UE level measurements; and
- To define a method for the reporting of Trace, MDT and 5GC UE level measurements results across the management interfaces.
Clause 4 details the various Trace records content, Clause 5 defines GPB trace format for NR, Annex A provides Trace, MDT and 5GC UE level measurements 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,MDT and 5GC UE level measurements files examples, Annex G provides normative GPB trace record schema and examples.
Trace and MDT concepts and requirements are covered in TS 32.421 [2] . The 5GC UE level measurements definitions and use cases are covered in 3GPP TS 28.558 [47]. TheTrace control and configuration management for trace, MDT and 5GC UE level measurements collection are described in 3GPP TS 32.422 [3].
The definition of Trace, MDT data and 5GC UE level measurements is intended to result in comparability of Trace, MDT data and 5GC UE level measurements produced in a multi-vendor wireless 3GPP networks.
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).
