Research On Heterogeneous Networks Location Management Based On Users Characteristics

With the rapid development of global mobile communication businesses, people propose the ever-increasing demands for the mobile communication technology. Mobile users in the process of moving, correspondent users want to be able to find the location of mobile users anytime, anywhere and communicate with them, so scholars have proposed location management technology. Now, heterogeneous networks consisting of various wireless technologies which can provide users with voice, data, multimedia and a wide variety of businesses, in heterogeneous networks environment, correspondent users want not only able to find the location of mobile users, but be able to find to the network which can meet QoS of users, so the research on heterogeneous networks location management has a certain significance.The research of this paper aims to reduce the total cost of heterogeneous networks location management. In this paper, the network model is heterogeneous networks consisting of the WiMAX network and WLAN network, WiMAX network covered the total network, WLAN network scattered in the WiMAX network. I analysis the three characteristics of the users speed, the call-arrival rate, call the type of business which can impact on the total cost of location management. My solution is that the mobile users always register location information on a network regardless of in which the network, the choice of this network is based on the different call businesses needs of correspondent users. Previous a solution of heterogeneous networks location management is to change the network structure itself, the first integration of the two networks, mobile users always register location information simultaneously on the two networks in the process of moving. Finally, in the MATLAB simulation, the simulation results show that, regardless of what the states of the mobile users which can always choose one of two programs, so that the total cost of location management will be the minimum.
