Question: What is the primary purpose of the Additional RRM Policy Index Information Element (IE) in the context of E-UTRAN?
Option 1: To provide additional information for RAT/Frequency priority independent of the Subscriber Profile ID, as complemented by overall E-UTRA and E-UTRAN stage 2 descriptions.
Option 2: To override Subscriber Profile ID settings for load balancing across different Radio Access Technologies (RATs).
Option 3: Exclusively for handover decisions based on QoS requirements without considering subscriber preferences.
Option 4: To manage the allocation of dedicated channels for high-priority subscribers in congested cells.
Explanation: The Additional RRM Policy Index IE is designed to offer supplementary information that does not rely on the Subscriber Profile ID, specifically for RAT/Frequency priority, enhancing network management and resource allocation without being directly tied to individual subscriber profiles.
