Abstract
A private wireless system is configured for providing a call hand-off capability for a mobile station communicating with a private base station operating in the wireless system. The call in the wireless system is handed off to the public cellular system whenever the mobile station is moved near the fringe of the coverage area provided by the private base station. Once the hand-off is initiated in the private base station, a process is executed in which the private base station and a local exchange carrier cooperatively switch an active call from an existing wireless communications path established between the private base station and the mobile station to a newly created wireless communications path established between the mobile station and a public base station in the cellular system.
