Abstract

In a handover from an asynchronous radio network to a synchronous system, long code state information and activation time are transmitted. The method of transmitting long code state information and activation time includes the step of acquiring handover-related information from a neighboring synchronous system by the asynchronous radio network. In the handover, the synchronous system transmit a first message including activation time information and long code state information to the mobile station by the asynchronous radio network and after receiving the activation time information and the long code state information, makes use of the long code state information based on the activation time information by the mobile station.
