Abstract: Based on the combination of instant method with statistical method, a target prediction scheme for handoff in NGI is designed by use of statistical prediction and historical handoff record to form a fuzzy decision tree. If there exist several target cells predicted, an instant prediction scheme runs to compute the accessing probability of each and all predicted target cells in accordance to the user's current information such as position, moving speed/direction and average call duration, then the maximum addressing probability is picked out as the handoff target cell. Simulation results showed that the proposed scheme has higher hitting rates at different users' movement speeds in comparison with those schemes simply based on statistical prediction or instant prediction, with a better overall performance provided.
