Question: What is the primary purpose of the Location Reporting Control procedure in UTRAN's Iu interface, as utilized by the Core Network (CN) in relation to User Equipment (UE)?
Option 1: To manage UE mobility between different Radio Access Networks (RANs)
Option 2: To establish or release dedicated bearer resources for a UE
Option 3: To authenticate a UE before granting network access
Option 4: To request location and optionally velocity information of a specific UE
Explanation: The correct answer aligns with the defined purpose of the Location Reporting Control procedure, allowing the Core Network (CN) to obtain a UE's location data, and if desired, velocity information, utilizing connection-oriented signalling over UTRAN's Iu interface for reliable communication.
