Question: When updating the 5GS NAS Security Context on a USIM, what additional consideration must the Mobile Equipment (ME) take to prevent excessive UICC memory wear out?
Option 1: Ensure the update is performed during a specific time window when network usage is low.
Option 2: Follow rules and procedures specified in the 5G System Security architecture and procedures document.
Option 3: Limit the number of updates based on a counter stored in another EF (Elementary File).
Option 4: Require explicit user confirmation for each update.
Explanation: To prevent UICC memory wear out due to excessive writing, the ME must adhere to specific guidelines when updating the 5GS NAS Security Context. These guidelines, outlining security architecture and procedures for the 5G System, ensure updates are managed to minimize memory degradation, highlighting the importance of standardized security protocols in maintaining both security and device integrity within telecom networks.
