Abstract :
The third generation (3G) communications will be a major move toward seamless high-quality wireless services that provides more and more data transmission capabilities using the IP packets. Therefore, the mobility management will enable different mobile networks to interoperate with each other to ensure terminal and personal mobility and global mobility services. In this paper, we will propose several mobility management schemes in two-tier cellular networks and compare the system performance. In addition, an overflow threshold is assumed in the mobility management scheme to avoid too many overflows occurred to reduce the blocking and dropping probabilities.
