ETSI TS 132 421

ETSI TS 132 421 describes the requirements for the management of Trace and the reporting of Trace data(including FDD mode and TDD mode) across UMTS networks or EPS networks as it refers to subscriber tracing(tracing of IMSI or Public User Identity) and equipment tracing (tracing of IMEI or IMEISV). Trace also includes theability to trace all active calls in a cell or multiple cells (Cell Traffic Trace). The present document also includes thedescription of Service Level Tracing (tracing of a specific service). It defines the administration of Trace Sessionactivation/deactivation by the Element Manager (EM), the network or User Equipment (UE) itself via signalling, thegeneration of Trace results in the Network Elements (NEs) and UE and the transfer of these results to one or moreOperations Systems, i.e. EM(s) and/or Network Manager(s) (NM(s)).

GSM Trace is outside of the scope of this specification (see [7]).

The present document also describes the requirements for the management of Minimization of Drive Tests (MDT)across UMTS networks or EPS networks and Radio Link Failure (RLF) reporting across EPS networks.

The present document is built upon the basic Subscriber and UE Trace concept described in clause 4.The high-level requirements for Trace data, Trace Session activation/deactivation and Trace reporting are defined inclause 5. Clause 5 also contains an overview of use cases for Trace (the use cases are described in Annex A). Clause 6defines the requirements for managing MDT. Clause 7 defines the requirements for managing RLF reports.Tracecontrol and configuration management are described in 3GPP TS 32.422 [2], and Trace data definition and managementare described in 3GPP TS 32.423 [3].
