  • Method and apparatus for error correction ciphering in mobile communication system
    Patent number: 8867391
    Abstract: A method for error correction deciphering of a receive apparatus in a mobile communication system includes receiving a Packet Data Convergence Protocol (PDCP) packet. The method also includes, when error correction ciphering is set, acquiring a partial Hyper Frame Number (HFN) from the PDCP packet. The method further includes comparing the partial HFN and the receive apparatus's own lower HFN of a constant bit count. The method still further includes, if the partial HFN and the receive apparatus's own lower HFN of the constant bit count are different from each other, performing an HFN correction function.

  • TCP RECOVERY METHOD AND APPARATUS
    Publication number: 20140204918
    Abstract: A method for Transmission Control Protocol (TCP) recovery in a transmitter for a wireless communication system is provided. The method includes detecting an event for releasing a Radio Resource Control (RRC) connection with a receiver, storing a TCP packet for the receiver when the RRC connection is released, reestablishing the RRC connection with the receiver, determining whether a session for the stored TCP packet exists, and transmitting the stored TCP packet to the receiver when determined that the session for the stored TCP packet exists.
