Question: In a 5G System with Service Based Architecture, what is the recommended approach for conveying updates to Load Control Information (LCI) by the sender to ensure effective load balancing?
Option 1: Convey every small variation in Load Metric (e.g., granularity of 1 unit) to target receivers as soon as possible.
Option 2: Update LCI only when the Load Metric remains static for a predefined duration (e.g., 5 minutes).
Option 3: Refrain from advertising minor variations (e.g., < 5 units in Load Metric), conveying updates only for significant changes to ensure useful improvement in NF service producer selection logic.
Option 4: Always convey LCI updates at fixed intervals (e.g., every hour), regardless of Load Metric fluctuations.
Explanation: This approach balances the need for timely updates with the processing efficiency of the receiver. Conveying only significant changes (> 5 units in Load Metric) ensures that the receiver's NF service producer selection logic benefits from the update, without overwhelming the system with minor, potentially inconsequential adjustments. This method aligns with the principle of achieving effective load balancing while considering the receiver's processing requirements.
