As the growth of the technology, Internet has developed rapidly. For many people, Mobile Internet has become a necessity of life. This situation causes users to require higher transmission speeds on Mobile Networks. In order to solve this problem, the network standard agencies are proposing new network standards like LTE and WiMAX. The standard proposed by 3GPP, LTE is 4G technology and a major step forward for the communications industry. Many countries are developing in LTE Systems.
In wireless mobile network environment, users may have some move case during communication service. Handover enables users with ongoing communication to move to another base station without any interruption. By considering the random walk movement, usually lead to performing some unnecessary handovers. These cause the reduction of system capacity.
Therefore, in order to make full use of network resources, we proposed a handover technique based on user mobility in this paper. The simulation results show that the proposed algorithm can obviously reduce unnecessary handovers.
