ABSTRACT:
The present invention discloses a method for improving a call quality by increasing the output of a mobile station over the reverse link by adjusting threshold range of a system's predetermined E.sub.b /N.sub.o value in the event that the transmission output of the mobile station is stopped in a reverse power control of a cellular system, and by comparing the measured E.sub.b /N.sub.o ratio to a predetermined threshold E.sub.b /N.sub.o ratio to increase/decrease the mobile station transmit power. The method includes steps of adjusting the predetermined threshold E.sub.b /N.sub.o ratio by monitoring the call quality in a forward frame, and repeatedly increasing/decreasing the mobile station transmit power accordingly.
