4.3 Service Level Tracing for IMS high level Architecture |R12| p. 15
There are two ways in which to activate service level trace for IMS:
- Trace activation at the UE, and
- Trace activation at an IMS NE.

Figure 4.3.2 represents the high-level view of the architecture of Signalling Based Activation/Deactivation at an IMS NE required to support Service Level Tracing for IMS. Figure 4.3.2 is only showing the interfaces in principle. Details of Service Level Trace Activation/Deactivation are defined in TS 32.422.

Service Level Tracing for IMS at the IMS NE
Figure 4.3.3 represents the high-level view of the architecture of Trace Reporting.
Figure 4.3.3 illustrates the reporting context for Service Level Tracing for IMS from the UE and is only showing the interfaces in principle. The reporting context for Service Level Tracing for IMS from the IMS NE is illustrated in Figure 4.2.3: Architecture for High-level view of Trace Reporting .
