Abstract:
1. A femtocell base station comprising: a communication module operable to communicate with a wireless terminal; a monitoring module operable to directly monitor wireless signals transmitted by the wireless terminal to a macrocell base station; an information determination module operable to determine whether the monitored wireless signals comprise attempt-to-connect information indicating an attempt to connect to the macrocell base station; an analysis module operable to determine whether the wireless terminal is located in a femtocell coverage area periphery of the femtocell base station based on the monitored wireless signals, wherein the femtocell coverage area periphery of the femtocell base station is within a macrocell coverage area periphery of the macrocell base station; and a management module operable to transmit a presence checking signal to the wireless terminal, if the monitored wireless signals comprise the attempt to connect information and the wireless terminal is in the femtocell coverage area periphery, wherein the management module does not transmit the presence checking signal to the wireless terminal if the monitored wireless signals comprise the attempt-to-connect information and the wireless terminal is not in the femtocell coverage area periphery.
