Landslide Performance Test System – Release 24.3 September 2024

Trace Data

The Trace Data tab is enabled via the HSS Server Tab Include Trace Data field via the HSS Node Test Case. It will include the Trace-Data AVP in the Subscription-Data-AVP for the S6a/S6d interfaces. Per 3GPP TS 32.422, TS 29.272 and TS 29.002.

Trace Data Tab describes the mechanisms used for the control and configuration of the Trace, Minimization of Drive Test (MDT) and Radio Link Failure (RLF) reporting functionality at the EMs, NEs and UEs. For Trace functionality,  it covers the triggering events for starting/stopping of subscriber/UE activity traced over 3GPP standardized signalling interfaces, the types of trace mechanisms, configuration of a trace, level of detail available in the trace data, the generation of Trace results in the Network Elements (NEs) and User Equipment (UE) and the transfer of these results to one or more EM(s) and/or Network Manager(s) (NM(s)). For MDT, it also covers logged MDT and immediate MDT mechanisms in both area based and signalling based scenarios.

The HSS Server tab is used to define the information in LTE requests sent from the HSS node to the MME/SGSN.

Trace Event List

Trace Event List

Triggering events

This mandatory parameter defines when to start a Trace Recording Session and which message shall be recorded first, when to stop a Trace Recording Session and which message shall be recorded last respectively. The messages in the start triggering event tables indicate the transaction to be recorded first and the starting time of the Trace Recording Session within a Trace Session for the traced MS/subscriber in the given NE.

The messages in the stop  triggering event tables indicate the transaction to be recorded last and the stopping time of the Trace Recording Session.
