A new trigger mechanism of handover based on the regular mobile route and the handover invitation

For the traditional trigger mechanism of handover based on the received signal strength has uncertainty and low reliability under a high speed mobile environment, the quality of service for users is greatly declined. The cooperative cell-cluster is constructed according to the regular mobile route of the mobile terminal and the location information of its adjacent base station, and a new trigger mechanism based on based on the regular mobile route and the handover invitation is proposed in the paper. The handover is more timely, accurate and reliable by new mechanism in the communication environment which the mobile rout is relatively fixed and more regular, and mobile speed is relatively high. But also the mechanism can make the handover process to shorten the time of handover, and prevent the occurrence of “ping pong handover” phenomenon. Moreover, it can improve the speed and efficiency of handover, and the user quality of service.
