Question: What two components are used to construct an S-Temporary Mobile Subscriber Identity (S-TMSI) for efficient radio signaling in mobile networks?
Option 1: MMEC (Mobility Management Entity Code) and AMF Region ID
Option 2: M-TMSI (Mobile-TMSI) and MCC (Mobile Country Code)
Option 3: MMEC (Mobility Management Entity Code) and M-TMSI (Mobile-TMSI)
Option 4: GUTI (Globally Unique Temporary UE Identity) and AMF Set ID
Explanation: The correct construction of an S-TMSI, as per telecom standards for efficient radio signaling (e.g., paging and Service Request), involves combining the Mobility Management Entity Code (MMEC) with the Mobile-TMSI (M-TMSI). This combination enables more streamlined network operations.
