Dynamic switching Base Station (BS) to improve the utilization is very important for reducing the energy consumption. Most of existing dynamic switching BS schemes require the switching threshold to be set in advance. The fixed switching threshold, however, fails to apply in practical two-tier femtocell networks, for it is difficult to precisely model that it may result in different switching operations and subsequent worse system performance. In this paper, the authors propose an adaptive BS switching scheme to regulate the threshold considering the time varying characteristic of the traffic profile in the two-tier femtocell networks.
