Abstract
The handover method includes the steps of the base stations of the synchronous mobile communication network transmitting dummy pilot signals for the asynchronous mobile communication network, the mobile communication terminal, for which call connection with the asynchronous mobile communication network is performed through the asynchronous wireless device, determining whether the dummy pilot signals for the asynchronous mobile communication network have been received through the asynchronous wireless device; the mobile communication terminal requesting handover from the asynchronous mobile communication network if it is determined that the dummy pilot signals for the asynchronous mobile communication network have been received; and the asynchronous mobile communication network determining that handover is possible, notifying the mobile communication terminal of the determination that handover is possible, and the asynchronous mobile communication network requesting handover to the synchronous mobile communication network, thus performing handover.
