Abstract: PURPOSE: A HSSCCH detection apparatus of a communication terminal and a method thereof are provided to decide decoding reliability of HSSCCH more accurately by comparing a difference value between a maximum value and a minimum value of the decoding reliability with a critical value. CONSTITUTION: A channel decoding unit proceeds Viterbi decoding of HSSCCH (High Speed Shared Control Channel)(613). The channel decoding unit checks decoding reliability of the HSSCCH(615). If a difference value between a maximum value and a minimum value of the decoding reliability by HSSCCH exceeds a critical value, the channel decoding unit detects the HSSCCH corresponding to the maximum value(625,627). The channel decoding unit proceeds demodulation about the second part of HS-SCCH and a HSPDSCH(High Speed Physical Downlink Shared Channel).

Abstract: A roaming service method for a fast and secure wireless network is provided. In an embodiment of the present invention, an AP, which an STA associates with, transmits security keys needed for roaming to neighbor APs of the AP. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key. In another embodiment of the present invention, an authentication server transmits security keys needed for roaming to neighbor APs to which the STA is likely to move, so that when the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key.

Abstract: A method for generating a security key in a wireless network is provided to perform a rapid communication between a mobile terminal and an access point by minimizing a time for a roaming service by simplifying roaming procedure in a wireless information communication network. A reception process is performed to receive a first level pairwise master key derived from a predetermined master key from a server(903-907). A first deriving process is performed to derive a pairwise master key from the first level pairwise master key(909). A second deriving process derives a second level pairwise master key for at least one adjacent access point from the first level pairwise master key(911). The adjacent access point is used for deriving a pairwise transient key from the second level pairwise master key.

Abstract: PURPOSE: A Doppler spread estimation method and a device in mobile communications networks are provided to effectively detect aliasing by using Bessel function in the process of Doppler frequency estimation based on PSD(Power Spectral Density) peak detection. CONSTITUTION: An estimation part(420) temporarily estimates a maximum Doppler frequency by using channel values sampled in a frame according to a first cycle. A judgment part(450) produces at least one correlation value among at least one channel value additionally sampled in the frame and at least one channel value sampled according to the first cycle. The judgment part judges the generation of aliasing by using the correlation value. A determination part(460) determines a final maximum Doppler frequency according to the generation of the aliasing.

Abstract: An error detecting device for detecting error in orthogonal frequency division multiple access system and a method thereof are provided to increase accuracy of error detecting by comparing a frame control header with fixed information. A decoder(300) decodes a frame control header, and outputs a decoded data. An error detector (320) confirms contradiction of the decoded data received from the decoder. If the contradiction exists in the decoded data, the error detector outputs error detection. A fixed information storage unit(310) stores fixed information, and reads the fixed information in the frame control header without decoding. The error detector confirms the fixed information, and compares the fixed information of the decoding data with the stored fixed information. If non-identical fixed information exists, the error detector outputs the error detection.
