This TS describes the requirements for the management of Trace and the reporting of Trace data (including FDD mode and TDD mode) across UMTS networks as it refers to subscriber tracing (tracing of IMSI or Private ID) and equipment tracing (tracing of IMEI or IMEISV). Trace also includes the ability to trace all active calls in a cell or multiple cells (Cell Traffic Trace).
This TS also includes the description of Service Level Tracing (tracing of a specific service). It defines the administration of Trace Session activation/deactivation by the Element Manager (EM), the network or User Equipment (UE) itself via signalling, the generation of Trace results in the Network Elements (NEs) and UE and the transfer of these results to one or more Operations Systems, i.e. EM(s) and/or Network Manager(s) (NM(s)).
