Question: What action does the HLR (Home Location Register) take when the trace status is True during a Home Subscriber Trace deactivation process, and what message is sent to which entity?
Option 1: The HLR updates the tracedHomeSubscriberInHlr object instance and sends an UPDATE-TRACE-MODE message to the MSC (Mobile Switching Center).
Option 2: The HLR sends a MAP-DEACTIVATE-TRACE-MODE message to the VLR (Visitor Location Register) before deleting the tracedHomeSubscriberInHlr object instance.
Option 3: The HLR immediately deletes the tracedHomeSubscriberInHlr object instance without sending any messages and notifies the OSF (Operations System Function) of completion.
Option 4: The HLR changes the trace status to False in the tracedHomeSubscriberInHlr object instance and sends a TRACE-STATUS-CHANGE message to the SGSN (Serving GPRS Support Node).
Explanation: When deactivating a Home Subscriber Trace, if the trace status is True, the HLR initiates the deactivation by sending a MAP-DEACTIVATE-TRACE-MODE message to the VLR. This step synchronizes the trace status across network elements before the trace is fully deactivated, involving deleting the tracedHomeSubscriberInHlr object instance in the HLR, ensuring consistency and proper cleanup of trace configurations.
