  • Method and apparatus for transmitting and receiving paging message using band information in wireless communication system
    Patent number: 8634350
    Abstract: A method and an apparatus for transmitting and receiving a paging message in a wireless communication system are provided. A Base Station (BS) transmits, to a Mobile Station (MS) in an idle mode, a Paging Group IDentification Information (PGID_Info) message including paging group information for a paging group to which the BS belongs, and frequency band-specific paging carrier information for indicating at least one of paging carriers included in each of a plurality of frequency bands operated by the BS. The BS determines a paging carrier for transmitting the paging message among paging carriers included in a frequency band supported by the MS, and transmits the paging message to the MS using the determined paging carrier. By doing so, reception of the paging message in the frequency band supported by the MS is guaranteed, thereby preventing the unnecessary location update procedure.

  • Method and apparatus for encrypting short data in a wireless communication system
    Patent number: 8625798
    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.
