Question: In a 5G system, when utilizing subscription-based routing to forward all traffic from specific subscribers' UEs to a target Public Land Mobile Network (PLMN), what is the primary goal of the forwarding mechanism in relation to the Home PLMN (HPLMN)?
Option 1: To maximize traffic handling capabilities within the HPLMN for enhanced user experience.
Option 2: To minimize traffic within the HPLMN, utilizing efficient forwarding means for selected UEs.
Option 3: To establish direct billing relationships between the target PLMN and subscribers of the HPLMN.
Option 4: To enforce stricter security protocols for roaming UEs in the target PLMN.
Explanation: The correct answer, Option 2, aligns with the requirement that the forwarding mechanism should minimize traffic in the HPLMN to efficiently handle the forwarding of selected UEs' traffic to the target PLMN. This approach optimizes network resource utilization in the HPLMN, ensuring that only necessary traffic is processed locally while redirecting other traffic as per the subscription-based routing policy.
