Question: In inter-network settlement for charging and billing, as per 3GPP standards, what is the primary goal of allowing each party to meter charge flows independently?
Option 1: To enable real-time payment processing between interacting parties.
Option 2: To facilitate the matching of recorded values at both sides of an interface, minimizing imbalance in charge flow.
Option 3: To allow for the dynamic adjustment of billing rates based on network congestion.
Option 4: To simplify the process of auditing for regulatory compliance.
Explanation: The primary goal of independent metering in inter-network settlement is to ensure both parties can accurately track and match their recorded charge flows, identifying discrepancies or imbalances, thus maintaining billing and settlement integrity between interacting telecom network entities.
