Question: In a 5G System (5GS), when applying Lawful Interception to a Fixed Network user equipment (FN-RG) connected via Wireline-5G Access Network (W-5GAN), what key difference in implementation should be considered compared to traditional UE-based interception?
Option 1: The FN-RG requires additional 3GPP-based subscriber credentials for lawful intercept.
Option 2: The FN-RG may not have a globally unique PEI and lacks 3GPP-based subscriber identity information.
Option 3: Lawful Interception for FN-RG via W-5GAN is governed by different 3GPP specifications than those for UE.
Option 4: The presence of FN-RG necessitates dual-mode (wireless and wireline) interception capabilities.
Explanation: This option correctly highlights the key differences in applying Lawful Interception to an FN-RG connected via W-5GAN, as opposed to traditional User Equipment (UE). Specifically, it notes that an FN-RG may lack a globally unique PEI and does not hold any 3GPP-based subscriber credentials or identity information, which are crucial considerations for implementing lawful intercept in this scenario.
