Abstract:
In a radio communication system, a method for initiating communication between a base station and a mobile station, comprising the steps of:notifying a base station whether a mobile station requires support; determining, by the base station, whether the mobile station requires support for a call handoff or for a call set-up; determining a reduced initial power level for transmission from the base station to the mobile station, wherein the value of the reduced power level is a function of whether the mobile station requires support for a call handoff or for a call set-up, the reduced initial power level being a difference between a full power level of the base station and a sum of a handoff hysteresis zone value for a cell in which the base station is located and a handoff hysteresis zone value for a cell which is supporting the mobile station prior to the call handoff; and transmitting from the base station to the mobile station at the reduced power level.
