  • Patent number: 8437753
    Abstract: There are provided a method for managing neighbor Base Station (BS) information in a mobile communication system, and a system thereof. A femto Access Service Network-Gateway (ASN-GW) controls at least one femto BS, manages scan information that an MS served by a macro BS requires in measuring at least one signal strength by scanning the at least one femto BS, creates the scan information in a format of Downlink Channel Descriptor (DCD) and Uplink Channel Descriptor (UCD) information, and transmits the scan information to the macro BS. The macro BS periodically broadcasts neighbor BS information of the femto BS, which includes the scan information, to MSs in its coverage using a Neighbor Advertisement (NBR-ADV) message.

  • Patent number: 8428603
    Abstract: A system and method for performing paging in an area where a macro Base Station (BS) and a femto Access Services Network (ASN) are linked in a mobile network are provided. The method includes, during handover of a Mobile Station (MS) between a macro ASN and a femto ASN, a first gateway of a current ASN acquires paging group information of a previous ASN. Upon request for paging from the MS in the current ASN, the first gateway requests a BS of the previous ASN to transmit paging information to the MS based on the paging group information of the previous ASN. By doing so, paging success rate may be improved for an MS in coverage of a macro ASN linked to a femto BS, and the high paging success rate may be guaranteed regardless of whether the handover scheme is a controlled handover scheme or an uncontrolled handover scheme.

  • Publication number: 20070115891
    Abstract: A method is provided for transmitting/receiving data in a communication system. If a base station has data to transmit to a mobile station, the base station detects a service flow for transmission of the data, sets an identifier of the detected service flow in a message, and transmits the message to the mobile station. The base station performs a specific operation of the service flow with the mobile station according to the transmitted message, and transmits the data to the mobile station.

  • Publication number: 20060079235
    Abstract: A system and a method for performing a handover in a broadband wireless access communication system including a serving BS, target BSs adjacent to the serving BS, and the MS currently communicating with the serving BS. The method includes receiving neighbor ranging code information from the serving BS, transmitting the neighbor ranging code information to at least one target BS, and receiving information for the handover from the serving BS.
