Question: What is the primary purpose of using an Area Session ID in conjunction with an MBS Session ID?
Option 1: To uniquely identify a UE within a specific MBS Service Area.
Option 2: To uniquely identify an MBS session in a specific MBS Service Area, particularly for location-dependent content.
Option 3: To differentiate between multiple MB-SMFs and/or MB-UPFs assigned to the same MBS service area.
Option 4: To provide additional security features for MBS sessions.
Explanation: The correct answer is Option 2 because an Area Session ID, when combined with an MBS Session ID (such as TMGI or Source Specific IP Multicast address), serves to uniquely identify an MBS session within a specific geographic area, especially relevant for content that varies by location.
