Question: In the context of Lawful Interception in 3GPP networks, what type of information is explicitly excluded from Subscriber Controlled Input (SCI)?
Option 1: All network-initiated service modifications
Option 2: Information available in the Call Content (CC)
Option 3: Details of subscriber's device configuration
Option 4: Billing and charging related data
Explanation: Subscriber Controlled Input (SCI) does not include any information already available in the Call Content (CC), focusing on subscriber-initiated actions not reflected in CC, to accurately capture user-controlled inputs without redundantly processing call content data.
