Abstract
In a communications network, a remote unit communicates with another user via at least one base station. The network has a plurality of base stations controlled by a mobile switching center. Each base station of the plurality of base stations transmits an identifying pilot signal. To defining an area in which communication between a set of the base stations and the remote unit is forbidden, an auxiliary antenna transmits a silent region identifying pilot signal. The remote unit measures a signal strength of a set of identifying pilot signals corresponding to a neighbor set of base stations and measures a signal strength of the silent region identifying pilot signal. The remote unit sends a pilot strength measurement report to the mobile switching center via a first base station with which the remote unit has established communication. A handoff of the established communication between the remote unit and the first base station is initiated if the pilot strength measurement report comprises an entry corresponding to the silent region identifying pilot signal.
