Question: In a 5G system using Service Based Interface (SBI) for charging, how does the ConvergedCharging service operate when invoking with quota management but without including an amount in the Quota Requested information element?
Option 1: Decentralized unit determination
Option 2: Centralized unit determination and rating
Option 3: Hybrid of both decentralized and centralized unit determination
Option 4: No quota management is applied
Explanation: According to the principles outlined for charging in a 5G system, when the ConvergedCharging service is invoked with quota management but no specific amount is included in the Quota Requested information element, it defaults to operating in centralized unit determination and rating. This approach ensures that all rating decisions are made centrally, providing a unified management of quotas when explicit amounts are not predefined.
