Question: What is the primary purpose of transferring 'correlation information' over the X2-interface from the LI LCS Client to the DF2 in the context of Enhanced Location for IRI (Interception of IP related information) reporting?
Option 1: To provide a backup mechanism in case of positioning failure
Option 2: To enable billing based on location-specific services
Option 3: To correlate multiple location reports for a single target in IRI scenarios
Option 4: To authenticate the target's identity across different networks
Explanation: Correlation information is crucial for linking multiple location reports that pertain to the same target, especially in Enhanced Location scenarios for IRI reporting. This ensures that all relevant location data can be accurately associated with the target, facilitating comprehensive and coherent interception of IP-related information.
