  • Method for securing handover data integrity in mobile communication system and system thereof
    Patent number: 9432888
    Abstract: A method of performing an uncontrolled handover data integrity of a target Base Station (BS) is provided. The method includes receiving an initial access request message from a Mobile Station (MS) by the target BS, performing a negotiation for establishing a handover data integrity path with a serving BS through a serving Access Service Network-Gateway (ASN-GW) by the target BS, and generating a main data path and a first handover data integrity path with the serving ASN-GW according to a result of the negotiation by the target BS.
    Type: Grant

  • Apparatus and method for synchronization between scanning interval and multicast interval in broadband wireless access system
    Patent number: 9326269
    Abstract: Scanning cycle synchronization of a multicast service in a broadband wireless access system is provided. Multicast group information of a multicast group to which a Mobile Station (MS) belongs is received at the MS from an application server. A scanning cycle pattern and a scan offset of a multicast service corresponding to the multicast group are determined. A scanning cycle of the multicast is set according to the scanning cycle pattern and the scan offset. Scanning and reception of multicast data are performed according to the scanning cycle.
