Question: During GSM session termination, what action does the Mobile Equipment (ME) take with regards to subscriber-related information after receiving confirmation from the SIM that update procedures are completed?
Option 1: The ME retains all subscriber-related information elements in its memory for potential future use.
Option 2: The ME updates the subscriber-related information elements one last time before deactivating the ME/SIM link.
Option 3: The ME deletes all subscriber-related information elements from its memory.
Option 4: The ME transfers all subscriber-related information to an external storage device for backup.
Explanation: This is correct because, after the SIM confirms that all necessary update procedures are completed, the ME is required to delete all subscriber-related information elements from its memory, ensuring data security and alignment with the termination of the session.
