  • Publication number: 20150208378
    Abstract: An apparatus for an idle mode terminal is configured to perform a method for operating the idle mode terminal in a Machine to Machine (M2M) communication system. A paging message is received from the base station during a paging listening interval. The Apparatus determines whether an indicator indicating receipt of multicast group data is included in the paging message. When the indicator indicating the receiving of multicast group data is included, data transmitted via a downlink resource that uses an identifier mask of a multicast group to which a terminal belongs is received. Thereafter, a paging non-listening interval is entered.

  • Patent number: 9088890
    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.

  • Patent number: 9031036
    Abstract: An apparatus is capable of supporting an intra-BS handover of a Mobile Station (MS) that can distinguish a Relay Station (RS) and a Base Station (BS) in a multi-hop relay broadband wireless communication system. A handover of an MS in a multi-hop relay wireless communication system includes receiving a neighbor advertisement message. When a handover command message that initiates a handover to a target node is received, information on a target node is acquired, and an upper BS of the target node is identified. When the identified upper BS of the target node is the same as an upper BS of the serving node, control information that has been previously used in a serving node is used in the target node, and communication with the target node is performed.
