Claim 28:
29. A method comprising:
generating a Non-Access Stratum (NAS) message having a container that includes a user equipment (UE) configuration parameter update for a 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 the UE, wherein the NAS message is operable to:
(i) cause the UE to perform a first security check to verify the secured packet in 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) of the UE, the USIM of the UE being configured to store UE configuration parameters for the UE,
(iii) cause the USIM of the UE to perform a second security check to verify the UE configuration parameter update encapsulated in the secured packet of the container of the NAS message, and
(iv) if the second security check is successful, cause the UE to 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 container of the NAS message.
