Abstract
A mobile telecommunication system for performing a handoff from an asynchronous communication system to a synchronous communication system includes: at least one asynchronous base station; at least one synchronous base station neighboring to the asynchronous base station, wherein the synchronous base station transmits channel signals; at least one dual-mode mobile station for selectively communicating with the synchronous base station and the asynchronous base station; and a reception unit, coupled to the asynchronous base station, for receiving and decoding the channel signals to transmit decoded signals to the asynchronous base station, wherein the asynchronous base station transmits the decoded signals to the dual-mode mobile station, thereby performing a handoff operation.
