摘要： 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.

摘要： A signal converter having a memory bank and radix-2 Fast Fourier Transform (FFT) transforms an Orthogonal Frequency Division Multiplexing (OFDM) signal having a long preamble and data into an OFDM signal in the frequency domain, and outputs the transformed OFDM signal. The radix-2 FFT has a linear systolic array architecture, transforms the long preamble stored in the memory bank by FFT, then stores the transformed long preamble into the memory bank, transforms data input through a buffering process and data input directly by FFT, and stores the transformed data in the memory bank. The memory bank has four memories, stores the long preamble transformed or not transformed and outputs the stored long preambles or the transformed data for the purpose of demodulation as the transformed data is input. Data-processing delay and/or power consumption may be reduced during the operation of the FFT processor.

摘要： The present invention relates to a method of transmitting data in a handover between base stations. When a mobile terminal performs a handover between base stations in a wireless communication system, a gateway transmits data traffic to be transmitted to a mobile terminal by using an IGMP (Internet Group Management Protocol) to a serving base station being serviced to the mobile terminal and a target base station to which a handover of the mobile terminal is made in a bi-casting method. Accordingly, when the mobile terminal performs the handover between the base stations, the gateway transmits the data traffic in the bi-casting method. As a result, it is possible to efficiently use a resource of a user plane connection interval between the gateway and the base station, thereby minimizing the loss of data traffic transmitted in a downlink, that is, data.
