Question: In the context of Lawful Interception for Home NodeB (HNB) networks, what is the primary purpose of transferring HNB location information from the location verifying node to the Delivery Function 2 (DF2)?
Option 1: To enable the DF2 to authenticate the HNB's identity
Option 2: To facilitate the DF2 in performing its lawful interception functionality
Option 3: To allow the DF2 to optimize network traffic routing based on geographical location
Option 4: To provide the DF2 with data for billing and subscription management
Explanation: The correct answer is Option 2 because transferring HNB location information to the DF2 enables it to perform lawful interception functionality, involving accurate location and identification of targeted communications, a key aspect of lawful interception in telecommunications networks.
