20110128838 | OPTICAL PICKUP DEVICE - An optical pickup device capable of eliminating interlayer crosstalk which is responsible for fluctuation in control signals and error rate in data signals, thereby ensuring stable action for a multilayered recording disc with a narrow interlayer spacing.

The reflected beam coming from the active layer, which has been condensed, is reflected by the reflecting plane whose reflecting region is limited and the thus reflected beam is detected by the optical detector. The reflected beam coming from other layers is not reflected by the reflecting plane, so that interlayer crosstalk is reduced. | 2011-06-02 |

20110128934 | METHOD AND APPARATUS FOR SUPPORTING CO-LOCATED COEXISTENCE MODE - A method and apparatus for reducing interference between systems when a plurality of wireless access systems are co-located are disclosed. To support CLC mode, an MS in the CRC mode transmits a handover request message to a first Base Station (BS) to initiate a handover process, receives a handover command message acknowledging the handover request message from the first BS, transmits a ranging request message to second BS at network reentry after handover, and receives from the second BS a ranging response message including CRC start time information that set by the second BS. | 2011-06-02 |
20110128935 | APPARATUS AND METHOD FOR HANDOVER OF MS IN WIRELESS COMMUNICATION SYSTEM - An apparatus and method for handover of a Mobile Station (MS) in a wireless communication system are provided. The method includes, if a ranging request signal is received from the MS attempting access through a handover, determining if the BS and a serving BS of the MS are the same BS based on the ranging request signal, and, if the BS and the serving BS are the same BS, determining the effectiveness of a Cipher-based Message Authentication Code (CMAC) included in the ranging request signal using previous authentication information of the MS. The serving BS denotes a BS from which the MS has been serviced before the handover. The previous authentication information of the MS denotes authentication information that the serving BS has used for authenticating the MS. | 2011-06-02 |
20110128936 | METHOD AND APPARATUS FOR SUPPORTING IDLE MODE HANDOVER IN HETEROGENEOUS WIRELESS COMMUNICATION - A method for supporting an idle mode handover of an Single Radio Mobile Station (SR MS) by a target Access Service Network GateWay (ASN_GW) in a heterogeneous wireless communication system is disclosed. The method includes, upon detecting that an operation mode of the SR MS is to be changed from an idle mode to an active mode, acquiring an address of a Home Agent (HA) of the SR MS from a preregistered ASN_GW with which the SR MS has performed a preregistration operation, upon detecting that a Base Station (BS) is to set up a path with the preregistered ASN_GW, transmitting a message, including the address of the HA and requesting to set the target ASN_GW as a new Foreign Agent (FA) of the SR MS, to the preregistered ASN_GW, and upon receiving a message, requesting to register the target ASN_GW as the new FA of the SR MS, from the preregistered ASN_GW, setting up a data path with the HA, and then registering the target ASN_GW as the new FA of the SR MS. | 2011-06-02 |
