WiBro(Wireless Broadband) is an emerging technology for portable Internet to support high speed rate. The communication infrastructure is the cellular system and is designed to maintain communication connectivity of mobile terminal at speeds of up to 60 km/h. The WiBro provides handover to support seamless communication. When the signal strength, coming from neighbor BS, is stronger than the threshold, the handover procedure is initiated. But, it can't be predicted whether the MS will really go out of the current cell or not. If the moving direction and speed of MSs are considered, it is possible to discriminate unnecessary efforts for handover connections. In this paper, we propose an efficient direction and speed based handover connection control schemes for increasing the utilization of channels and reduce a probability of new connection blocking rate. Some results of computer simulation are evaluated to show the effectiveness of the proposed method.
