starting a first timer based on the slice deregistration inactivity timer, wherein when the first timer expires, the UE locally removes the S-NSSAI from the Allowed NSSAI, and wherein when the UE does not trigger a Mobility Registration Update and an Allowed NSSAI becomes empty after expiry of the validity time, the UE enters deregistered state implicitly.
