Question: What is the primary purpose of the Lawful Interception Mirror IMS State Function (LMISF) in a VPLMN when using S8HR as the roaming architecture?
Option 1: To manage EPS Bearer IDs for all UEs in the network.
Option 2: To support lawful interception of voice services by tracking and mirroring IMS state for inbound roamers with S8HR.
Option 3: To optimize media packet delivery for IMS sessions across different networks.
Option 4: To handle authentication procedures for roaming UEs.
Explanation: The LMISF's main function is to support lawful interception of voice services in S8HR roaming scenarios, involving mirroring and managing IMS state for inbound roamers with S8HR, to meet lawful intercept requirements for voice services in a visited network.
