摘要

A method for converting a communication channel when a mobile station moves from one service area to another is disclosed. The mobile station apparatus is configured to transmit the transmission phase of the frame synchronous signal received from the first base station apparatus having the actual communication channel with the mobile station apparatus and the transmission phase of the frame synchronous signal received from the second base station apparatus scheduled to newly set the communication channel with the mobile station apparatus And detects the phase difference between the transmission phases. The mobile station transmits the phase difference information indicating the phase difference to the first base station apparatus through the communication channel. The first base station device receiving the phase difference information transmits information to the second base station device to correct its data phase to be transmitted to the mobile station device. As a result, the phase synchronization of the frame transmitted from the two base station apparatuses is guaranteed, and the soft handover is successfully realized.
