Question: In 5G System (5GS) Session Management Function (SMF), how are multiple Grouped Information Elements (IEs) of the same type but for the same purpose distinguished when sent within the same message level?
Option 1: By assigning a unique flag to each Grouped IE
Option 2: By ensuring they have exactly the same IE type to represent a list
Option 3: By using different length values in the TLV encoding for each
Option 4: By placing them in separate scope levels without changing the IE type
Explanation: According to the specifications for Grouped IEs in the context of 5GS SMF, when multiple Grouped IEs of the same type and purpose are sent within the same message level, they must have exactly the same IE type. This convention allows these IEs to be correctly interpreted as representing a list, ensuring consistency and clarity in message processing within the telecom network.
