Question: What is the primary purpose of the Subscription Profile Repository (SPR) in the Policy and Charging Control (PCC) architecture, as related to a User Equipment's (UE) connection?
Option 1: To store temporary IP-CAN bearer level PCC rules for each UE session.
Option 2: To manage the overall network capacity and allocate resources dynamically.
Option 3: To provide subscriber/subscription-related information for subscription-based policies and IP-CAN bearer level PCC rules to the Policy and Charging Rules Function (PCRF).
Option 4: To handle billing and charging processes directly for each UE's data usage.
Explanation: The SPR's key role is supplying crucial subscriber and subscription data, vital for the PCRF to make informed decisions regarding policy enforcement and charging rules at the IP-CAN bearer level, ensuring personalized service delivery and accurate billing based on individual subscriber profiles.
