Claim 18:
19. An Access and Mobility Management Function (AMF) element comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the AMF element to perform at least:
generating a Non-Access Stratum (NAS) message having a container that includes a UE configuration parameter update for the UE, at least a portion of the UE configuration parameter update being encapsulated in a secured packet of the container of the NAS message; and
transmitting the NAS message towards a User Equipment (UE),
wherein the NAS message is operable to:
(i) cause the UE to perform a first security check to verify the secured packet of the NAS message,
(ii) if the first security check is successful, cause the UE to forward the secured packet to a Universal Subscriber Identify Module (USIM) in operable communication with the UE,
(iii) cause the USIM to perform a second security check to verify the portion of the UE configuration parameter update encapsulated in the secured packet of the NAS message, and
(iv) if the second security check is successful, update one or more of the UE configuration parameters in the USIM based on the UE configuration parameter update encapsulated in the secured packet of the NAS message.
