Abstract: Embodiments of the inventive concept herein provide a method and User Equipment (UE) for handling PLMN selection involving Proximity Based Services (ProSe) communication. The method includes detecting one of a PLMN selection due to the ProSe communication followed by a manual Closed Subscriber Group (CSG) cell selection, and a manual CSG cell selection followed by the PLMN selection due to the ProSe communication, when the UE has stored a duplicate value of a Registered PLMN (RPLMN) and a duplicate of a PLMN selection mode. Further, the method includes preserving the stored duplicate value of the RPLMN and a stored duplicate of the PLMN selection mode.

Abstract: A method and apparatus is capable of encrypting short data in a wireless communication system When a terminal generates a short data burst in idle mode, the apparatus generates a Traffic Encryption Key (TEK) using a Cipher-based Message Authentication Code (CMAC)-TEK prekey derived from an Authorization Key (AK) related to Security Association (SA) between the terminal and a Base Station (BS). A nonce is constructed with a Packet Number (PN) identical to an uplink CMAC PN (CMAC-PN_U) transmitted together with a Ranging Request (RNG-REQ) message carrying the short data burst The short data burst is encrypted using the TEK and the nonce. A Medium Access Control (MAC) Protocol Data Unit (PDU) is generated by attaching a MAC header and a CMAC digest for integrity protection to the RNG-REQ message carrying the encrypted short data burst. The MAC PDU is transmitted to the BS.
