Abstract: The present invention relates to a method for managing a group traffic encryption key (GTEK) in a wireless portable Internet system. In the method, for higher security of a group traffic service such as a multicast service, a broadcast service, and a multicast-broadcast service (MBS), a base station periodically generates and distributes a GTEK to a subscriber station served with the group traffic service. A lifetime of a group key encryption key (GKEK) used for encrypting a GTEK is set greater than that of the GTEK. That is, the GKEK is updated once while the GTEK is updated several times. According to the present invention, security for the group traffic service is increased while reducing radio resource consumption.

Abstract: Disclosed is a method of detecting signals at a receiver of a communication system with a multiple input multiple output antenna. With the signal detection method, a square of the distance between a received signal vector and a channel status-considered transmission symbol vector is calculated first, and the square of the distance is then classified into first and second components. The first component is minimized to calculate a plurality of first soft symbol estimates. A solution set of the first component is calculated on the basis of the plurality of first soft symbol estimates. The second component is minimized to calculate a plurality of second soft symbol estimates. A solution set of the second component is calculated on the basis of the plurality of second soft symbol estimates. A final solution set is calculated by doing the sum of the first component solution set and the second component solution.

Abstract: An apparatus for providing vehicle accident information periodically collects vehicle travel information, and stores vehicle travel information that is collected during an accident of a vehicle, in a vehicle black box. The apparatus for providing vehicle accident information collects information about other vehicles through communication with the other vehicles during the accident of the vehicle, and stores the collected information in the vehicle black box. Since the information about the other vehicles is collected through communication with the other vehicles as described above, it is possible to provide more accurate and efficient information required for dealing with the accident. In addition, vehicle accident information, which includes time when an accident occurs, location where an accident occurs, and the type of accident, is transmitted to a related agency such as a police station and a traffic center, so that it is possible to quickly deal with the accident.
