Mobility Prediction Handover Using User Mobility Pattern and Guard Channel Assignment Scheme

In the next generation of mobile communication networks, the radius of the cell will become smaller, causing more frequent handovers and disconnection of existing handover calls if the channel capacity for handover is insufficient. This paper proposes a mobility prediction handover scheme to prevent these phenomena. If the next cell into which a mobile user will move could be predicted, then the necessary bandwidth could be reserved to maintain the user’s connection. The proposed scheme predicts the next cell to which a mobile user will move, based on the user’s mobility pattern history and current mobility trace. In addition, this paper suggests a Mobility Prediction Guard Channel Reservation Scheme (MPGCRS) that adjusts guard channel size in accordance with the handover prediction ratio.
