Handover algorithm combined with location prediction in 3GPP LTE systems

Concerning the problem of the decline of 3GPP Long Term Evolution(LTE) system throughput caused by the frequent handover,a location prediction model based on user movement mechanism and changing probability of direction was proposed.The proposed model was combined with the standard handover algorithm of LTE.The model calculated the weight of each possible location using the changing probability of direction,then got the predicted received signal strength through summing.The simulation results show that the number of handover does not change obviously,but the system throughput is improved after using the combined algorithm.In addition,the proposed model is better than the traditional data mining prediction model.
