Abstract
A system and method for handing off a remote unit from a first base station to a second base station, in a cellular spread-spectrum communications network, without loss of data. The remote unit transmits data to the first base station at a first data rate, and receives a first spread-spectrum signal having a first signal quality from the first base station. The remote unit monitors the first signal quality and compares the first signal quality to a plurality of signal qualities of a respective plurality of received-spread-spectrum signals. The remote unit initiates handoff when any of a number of predetermined criteria are met. Upon initiating handoff to the second base station, the remote unit stores the data that would otherwise have been transmitted. Once handoff is complete, the remote unit transmits the stored data to the second base station at a second data rate, with the second data rate greater than the first data rate. Once the stored data has been transmitted, the remote unit transmits data to the second base station at a data rate and power level comparable to the first data rate and the first power level.
