Abstract
A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller transitions the UE from a Radio Resource Control (RRC) idle state to an RRC connected state, and after transitioning the UE from the RRC idle state to the RRC connected state, sends an initial Non-Access Stratum (NAS) message comprising a limited set of Information Elements (IEs) in cleartext, which are required to establish security between the UE and the service network, and a container IE carrying an initial NAS message Protocol Data Unit (PDU) ciphered with NAS security context to the service network via the wireless transceiver.
