The selection problem of an optimal accessing network for wireless heterogeneous networks handover

the existing studies focus mainly on selection handover between two networks. However

few research is done on 5G (5th Generation) ultra-dense network (UDN) handover selection. This paper studies the handoff technology of ultra-dense heterogeneous networks in 5G wireless communication system. We propose a method of joint vertical handoff based on area sensing Bayesian decision. This solution selects the optimal switching probability of each heterogeneous network to deal with ultra-dense network handover. The different scenarios are simulated for a mobile station (MS) which enters an ultra-dense network cell

moves in the cell and crosses the cells. Studies show that Bayesian decision method can accurately select the network

and therefore this solution can be applied to the application scenarios of ultra-dense heterogeneous networks.
