As the most potential way to improve the overall performance of the next generation wireless networks, femtocell has attracted much attention from vendors. To femtocell, hybrid access mode is a comprise access mode that operates between close access mode and open access mode. With this kind of access mode, not only the pre-registered users are able to access it, un-registered users could also gain benefits as long as there is available resources. In this paper, we propose a novel access control algorithm based on hybrid access mode. Simulation results show that this algorithm can decrease the outage rate of macro users without causing too much signaling overhead.
