Abstract
A handoff method in a cellular network for switching from an old base transceiver station (BTS) to a target BTS in an uninterrupted manner is provided according to the invention. The method includes the steps of determining the target BTS, establishing communication between the mobile station and the target BTS, wherein the mobile station receives communications continuously from both the old BTS and the target BTS, and terminating the transmission to the old BTS. The terminating step does not occur until after establishing communication between the mobile station and the target BTS.
