Question: In a 5G system with satellite access employing Store and Forward (S&F) Satellite operation, what can be applied on a per UE and/or satellite basis by the operator or a trusted 3rd party, subject to operator’s policies?
Option 1: S&F Data Retention Period and S&F Data Storage Quota
Option 2: Only Store Priority for Authorized UEs
Option 3: Forwarding Protocol Selection (e.g., TCP, UDP)
Option 4: Satellite Constellation Configuration
Explanation: In the context of S&F Satellite operation in a 5G system with satellite access, the operator or a trusted 3rd party has the capability to manage data handling on a granular basis. This includes applying specific retention periods for stored data (to ensure compliance with regulatory requirements and operational efficiency) and setting storage quotas (to manage satellite resources effectively). These controls are essential for optimizing the S&F Satellite operation, making Option 1 the correct answer.
