This annex describes the format of trace or MDT result files. Those files are to be transferred from the network (NEs or EM) to the NM.

The following conditions have been considered for the definition of this file format:

– The trace data volume and trace duration is not predictable. Depending on the data retrieval and storage mechanisms, several consecutive trace result files could be generated for a single traced call. The file naming convention shall allow rebuilding the temporal file sequences.

– Since the files are transferred via a machine-machine interface, the files should be machine-readable using standard tools.

– The file format should be independent from the data transfer protocol used to carry the file from one system to another.

– The file format should be generic across UMTS and EPS systems.

– The file format should be flexible enough to support further trace data types and decoded IEs, as well as vendor specific trace data.
