Question: How should an MME (Mobility Management Entity) respond if it receives a UE RADIO CAPABILITY INFO INDICATION message containing the UE Radio Capability for Paging – NR Format Information Element (IE) but missing the UE Radio Capability for Paging IE?
Option 1: Ignore the missing IE and process the received information.
Option 2: Request the UE to resend the complete information.
Option 3: Trigger a paging failure alert to the Operations and Maintenance (O&M) system.
Option 4: Consider it a logical error and handle according to predefined error handling procedures.
Explanation: In telecommunications, specifically within the context of E-UTRAN (Evolved Universal Terrestrial Radio Access Network), when an MME encounters inconsistencies in critical messages like UE RADIO CAPABILITY INFO INDICATION, it must adhere to strict protocols for error management. Given the scenario where a crucial IE (Information Element) is missing, the appropriate response aligns with treating the situation as a logical error. This approach ensures network integrity and functionality by triggering established error handling mechanisms, which could include notifications, retries, or specific corrective actions defined in the network’s operational guidelines (as hinted at in subclause 10.4 for general error handling, though not directly referenced here to maintain question independence).
