    Patent number: 5774809
    Abstract: In the method of this invention, a mobile station is constructed to receive predetermined signals from neighboring base stations as an indication of received signal strength. These signals are compared to the current traffic signal strength indicator and a resultant signal is calculated proportional to the differential signal strength. Only the current received signal strength indicator is transmitted to the base station in absolute value. All other indicators are reported as relative values.
