Question: In a 5G network, where are the 5G NAS security context parameters stored if the corresponding file is not present on the Universal Subscriber Identity Module (USIM)?
Option 1: On the Access and Mobility Management Function (AMF) server
Option 2: In a non-volatile memory in the Mobile Equipment (ME) along with the Subscription Permanent Identifier (SUPI) from the USIM
Option 3: Directly on the User Equipment's (UE) volatile memory for temporary use
Option 4: On an external secure element within the UE but outside the USIM
Explanation: If the corresponding file for storing 5G NAS security context parameters is not found on the USIM, these parameters are stored in a non-volatile memory within the Mobile Equipment (ME), ensuring persistence across power cycles, alongside the SUPI retrieved from the USIM, maintaining a secure association between the subscriber's identity and the security context.
