Method, femto base station and femto management system for load balancing

Serving femto BS forwards the subscriber's data traffic over the X2 interface is associated with the cell load if it exceeds a previously defined threshold value, the target femto base station. In this case, the serving femto base station and to lower the output power, reduced the coverage of serving femto cell, femto base station increases the target output power to enlarge the coverage of the target femtocell. Further, the target femto base station is thereby connected to the differential along the subscriber that transitions from the serving femto base station in the connected mode.
