A Novel Optimising Handover Method Based on User Behavior

Handover is the core procedure for assuring mobility of the users in any mobile network and its success rate is a key indicator of user satisfaction. In the current mobile networks, handover optimisation is done manually on a long timescale. In this paper, we introduce inter-NodeB coordination system and the parameters of user behavior and history data to optimise handover. First, we collect the data of user behavior, analyze the data and find the regular pattern with the help of history data. Then, signals are sent out to inform the eNodeBs along the regular path, so the eNodeBs along the regular path can make the handover preparation previously. When the user is coming, the mobile-phone can be switched to another cell quickly. If the user deviates from the regular path, the handover procedure is handled as traditional. We can use the history data to amend the handover process and make user return to the regular path. From simulation result, the advantage of saving time in handover procedure is significant.
