scope:

The present document describes Trace data definition and management. It covers the trace records content, their format and transfer.

The objectives of the present document are:

• To provide the descriptions for a standard set of Trace data;

• To define the common format of trace records; and

• To define a method for Trace results reporting across the management interfaces.

Clause 4 details the various Trace records content, Annex A provides Trace 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 files examples. Trace concepts and requirements are covered in TS 32.421 [2] while Trace control and configuration management are described in 3GPP TS 32.422 [3].

The definition of Trace data is intended to result in comparability of Trace 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).
