Abstract
Apparatuses, systems, and methods for refreshing a Global Unique Temporary Identifier GUTI of a user equipment UE.

The timer may be provided by the UE as a request for use by the AMF. Alternatively, the timer may be used by the UE and the UE may request the new GUTI upon expiry of the timer, e.g., using an existing message or a new message, as desired.
