Abstract
Operation commences with the cellular network infrastructure setting up a forward link and a reverse link with a cellular mobile station. The cellular network infrastructure transmits signals to the cellular mobile station on the forward link and receives signals from the cellular mobile station on the reverse link. The cellular network infrastructure monitors the quality of the reverse link. When the reverse link quality level meets a reverse link lost criteria, the cellular network infrastructure enters reverse link recovery mode of operation in which the transmit power of the forward link is increased in an attempt to recover the reverse link. During the reverse link recovery mode of operation, the cellular network infrastructure may determine that the reverse link quality meets a reverse link recovered criteria. When the reverse link quality meets the reverse link recovery criteria, the cellular network infrastructure exits the reverse link recovery mode of operation for the cellular mobile station and resumes normal power control operations. When the cellular network infrastructure determines that the reverse link recovery mode of operations fail, the cellular network infrastr…
