Abstract
In a cellular mobile radio system, a handoff method allows a mobile station to be handed off from one base station to another base station when an alarm case occurs in an operator controlled manner in an attempt to save the connection. A cell border is defined where a handoff is allowed from a first base station to a second base station by comparing the radio transmissions between a mobile station and the first and second base stations. The handoff border is then moved by an offset value to form an alarm case cell border, wherein an alarm case handoff from the first base station to the second base station is allowed only when the mobile station experiences an alarm case and is in the area bounded by the handoff cell border and the alarm case handoff border.
