21.9 Tracing macros<br />

21.9.1 Macro Trace_Subscriber_Activity_MSC<br />

The Trace_Subscriber_Activity_MSC is invoked in the MSC, when the MSC receives the<br />

MAP_TRACE_SUBSCRIBER_ACTIVITY indication from the VLR. The data of the primitive is checked and<br />

the tracing in the MSC is started if the content includes no errors. No response is returned to the VLR.<br />

The Trace_Subscriber_Activity_MSC macro is described in the figure 21.9/1.
