Question: What is the primary purpose of using the 5G-S-Temporary Mobile Subscriber Identity (5G-S-TMSI) in radio signalling procedures?
Option 1: To enable more efficient radio signalling procedures, such as paging and Service Request.
Option 2: To provide a unique identifier for the User Equipment (UE) in the 5G network.
Option 3: To authenticate the UE before establishing a connection with the Access and Mobility Management Function (AMF).
Option 4: To encrypt data transmitted between the UE and the AMF.
Explanation: The 5G-S-TMSI is used to enable more efficient radio signalling procedures, such as paging and Service Request. This is because it provides a shortened form of the 5G-GUTI, which allows for faster and more efficient communication between the UE and the AMF.
