    摘要: Disclosed are a method and a system for handover from a WCDMA network to a CDMA-2000 network by using a dummy pilot signal. The method comprises the steps of: a) a multimode terminal receiving a WCDMA signal level measurement message, turning on a CDMA-2000 modem mounted on the multimode terminal and transmitting a level value of the dummy pilot signal to a WCDMA system, when detecting the dummy pilot signal above a specific level from the WCDMA signal level measurement message; b) the WCDMA system determining whether to perform a handover or not based on the level value of the dummy pilot signal; c) the WCDMA system transmitting a handover request message to a CDMA-2000 system when it is determined to perform the handover; d) transmitting a handover command message from the WCDMA system to the multimode terminal; and e) allowing traffic to be switched to the CDMA-2000 modem of the multimode terminal.
