  • Publication number: 20060130145
    Abstract: The provided method and system is a method and system for analyzing the malicious code protocol and generating harmful traffic. The harmful traffic generating method constructs packet protocol information for generating a first attack packet corresponding to the TCP/IP protocol for generating network traffic, and then sets network vulnerability scanning for generating a second attack packet for carrying out network vulnerability scanning. Subsequently, the method constructs attack information for generating a third attack packet in the form of denial of service, and generates harmful traffic using the packet protocol information, network vulnerability scanning and attack information. Accordingly, performance testing of the network security system against malicious code attacks such as the Internet worm can be performed.

  • Publication number: 20060067279
    Abstract: A method of transmitting a data packet based on a transport format combination set (TFCS) using a hybrid automatic repeat request (HARQ) is disclosed. In the method, a user equipment (UE) receives a TFCS from a base station (BS) to select a transport format combination (TFC) for retransmitting a data packet and selects from the TFCS a TFC which corresponds to a maximum transmission power by which the data packet is retransmitted. Thereafter, the UE retransmits the data packet using the TFC of an initial transmission and a transmission power that corresponds to the TFC with the maximum transmission power of the TFCS.

  • Publication number: 20060034216
    Abstract: Transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal in association with a packet transmitted on an uplink is disclosed. The method includes the steps of receiving a packet transmitted from a user equipment, decoding the packet, and determining whether the packet has been successfully decoded, transmitting an ACK signal or a NACK signal, based on the decoding result. Different transmission powers are allocated for the ACK signal and the NACK signal. Alternatively, the transmission power for the NACK signal selectively has an OFF level. The present invention optimizes the transmission powers for downlink ACK/NACK signals in accordance with the required reception quality of each of the ACK/NACK signals, and thus, enables the system to operate efficiently.
