FEMTOCELL, BASE STATION, FEMTO GATEWAY, AND COMMUNICATION METHOD THEREOF

摘要

A femtocell, a base station, a femto gateway, and communication methods thereof are provided. The femtocell is connected to the femto gateway via the base station. The femtocell turns off its RF transceiver when the RF transceiver is idle for a predetermined time interval. When the base station determines that a mobile station enters its signal coverage, the base station transmits a notification signal to the femto gateway. After receiving the notification signal, the femto gateway transmits a turn-on signal to the femtocell via the base station. After receiving the turn-on signal, the femtocell turns on its RF transceiver and transmits an acknowledgement signal to the femto gateway. Since the femtocell only turns on its RF transceiver when a mobile station needs its service, the femtocell consumes less power. In addition, interferences between femtocells can be reduced.
