    Abstract: A system and method for reassembling packets in a packet relay node are provided. A packet relay node located between a transmitting node (i.e., a source node) and a receiving node (i.e., a destination node) inspects received packets to see if they are fragmented packets and reassembles a series of packets decided to be fragmented packets into an original packet, thereby reducing overhead and radio resource waste caused by duplicate transmission of IP headers having the same fragmented-packet information.

    Abstract: Provided are a high-speed Discrete Fourier Transform (DFT) apparatus and a method thereof. The high-speed DFT apparatus includes a zero padding unit, a Fast Fourier Transform (FFT) unit, and a preamble index decision unit. The zero padding unit receives a first input signal having a length of a prime number and changes the first input signal into a second input signal having a length of an exponentiation of 2. The FFT unit performs a FFT on the second input signal outputted from the zero padding unit. The preamble index decision unit detects a preamble index from an output signal from the FFT unit.

    Abstract: The present invention relates to a security association negotiation method of extensible authentication protocol (EAP) for authenticating a subscriber station user in a wireless portable Internet system. An exemplary security association negotiation method using a user authentication in a wireless portable Internet system according to an embodiment of the present invention includes following steps. A base station generates an authentication key for authenticating a user of a subscriber station. The base station receives a security association capability request message including security association capability information of the subscriber station from the subscriber station after generating the authentication key. The base station determines whether the base station is able to accept a security association capability of the subscriber station included in the security association capability request message. The base station transmits a security association capability response message including the security association capability information which is selected for a security association with the subscriber station by the base station when the security association capability of the subscriber station can be accepted. According to the present invention, a subscriber authentication for EAP may be efficiently performed without an additional message after a handover.

    Abstract: The present invention relates to a vertical handoff method. According to the present invention, a serving network of a mobile station is determined. Herein, the mobile station that can access a first network having relatively wide service coverage and a second network having relatively narrow service coverage in an area where service coverages of heterogeneous networks are overlapped. When accessing the serving network of the first network, it is determined whether a received signal strength received from the second network is greater than a first threshold value. In addition, a first vertical handoff is decided by using a result of prediction of a transition pattern of the received signal strength that is greater than the first threshold value. When the serving network is the second network, it is determined whether the received signal strength received from the second network is less than a second threshold value. By using a result of prediction of a transition pattern of the received signal strength that is less than the second threshold value, a second vertical handoff is decided. Herein, the first threshold value is greater than the second threshold value.
